AB  - Background: Shikonin is a naturally occurring naphthoquinone found in the roots of several genera of the Boraginaceae family, widely known for its numerous biological activities, such as antiinflammatory, antioxidant, antimicrobial and anticancer. In this study, the antitumor effect of six naphthoquinones isolated from the roots of Onosma visianii was evaluated using two cell lines, mouse melanoma B16 and highly aggressive rat glioma cell line C6. 
Methods and results: All examined shikonins dose-dependently decreased the viability of tested cells, with compounds 5 and 6 being the most potent ones and hence subjected to further analysis. The diminished viability of B16 melanoma cells was in correlation with detected caspase-mediated apoptosis. Importantly, observed altered cell morphology along with the loss of dividing potential upon exposure to both shikonins implied reprogram of B16 cell phenotype. Elevated expression of myelin basic protein indicated the acquirement of Schwann‐like cell phenotype, while detected autophagy might be connected to this phenomenon. On the contrary, upon exposure to both agents, C6 cells underwent specific cell death—anoikis, provoked by detachment from the extracellular matrix and compromised integrin signaling. Oppositely to compound 5, compound 6 realized anoikis in a caspase-independent manner and under sustained ERK1/2 activation, indicating the deviation from standard proanoikis signaling. 
Conclusions: Herein, we have pointed out the diversity and novelty in the mode of action of shikonin derivatives depending on the tumor cell features, which represents a good platform for new investigations of these promising natural compounds.

AB  - Multidrug resistance is a major challenge in clinical cancer therapy. In particular, overexpression of certain ATP-binding cassette (ABC) transporter proteins, like the efflux transporter ABCG2, also known as breast cancer resistance protein (BCRP), has been associated with the development of resistance to applied chemotherapeutic agents in cancer therapies, and therefore targeted inhibition of BCRP-mediated transport might lead to reversal of this (multidrug) resistance (MDR). In a previous study, we have described the introduction of a boron-carbon cluster, namely closodicarbadodecaborane or carborane, as an inorganic pharmacophore into a polymethoxylated 2-phenylquinazolin-4-amine backbone. In this work, the scope was extended to the corresponding amide derivatives. As most of the amide derivatives suffered from poor solubility, only the amide derivative QCe and the two amine derivatives DMQCc and DMQCd were further investigated. Carboranes are often considered as sterically demanding phenyl mimetics or isosteres. Therefore, the organic phenyl and sterically demanding adamantyl analogues of the most promising carborane derivatives were also investigated. The studies showed that the previously described DMQCd, a penta-methoxylated N-carboranyl-2phenylquinazolin-4-amine, was by far superior to its organic analogues in terms of cytotoxicity, inhibition of the human ABCG2 transporter, as well as the ability to reverse BCRP-mediated mitoxantrone resistance in MDCKII-hABCG2 and HT29 colon cancer cells. Our results indicate that DMQCd is a promising candidate for further in vitro as well as in vivo studies in combination therapy for ABCG2-overexpressing cancers.

AB  - Melanoma is considered the most aggressive type of skin cancer. Due to initial or
acquired resistance and numerous side effects, existing therapeutic regimens for metastatic
melanoma are not sufficiently effective. Therefore, melanoma remains associated with a
high mortality rate. Despite extensive therapeutic protocols, the curation rate for invasive
forms of tumors is quite low, and the question arises as to what is wrong with the current
approach in oncotherapy. The main criterion for the selection of new antitumor drugs is
primarily based on their ability to induce apoptosis. However, numerous literature data
link aggressive therapeutic approaches based on the induction of apoptosis in high grade
tumors, which are characterized by the presence of cells with a low-differentiated
phenotype, with tumor progression that occurs due to compensatory proliferation. The
solution to the problem lies in increasing the level of tumor differentiation, which will
decrease proliferation induced by apoptosis. Differentiation therapy represents a new
concept in the therapy of aggressive malignancies. Many differentiation agents are of
natural origin. In order to increase the efficacy and reduce the toxicity of conventional
therapies, standard therapeutic protocols are often combined with complementary
medicine, where the leading position is occupied by natural products isolated from
plants. Flavonoids are one of the largest and most diverse classes of secondary plant
metabolites, well-known for their pronounced anticancer potential. Prenylflavonoids
from the hop plant have a great potential to trigger a change of the malignant phenotype
into a quiescent, more functionally defined form, closer to the healthy counterpart of the
same or different tissue. This approach has mainly been unexplored, opening up many
possibilities in both scientific and commercial terms. The focus of this lecture will be
on prenylflavonoid - isoxanthohumol in the context of possible melanoma therapy and
the creation of protocols that would increase the effectiveness of existing conventional
chemotherapy.

plants. Flavonoids are one of the largest and most diverse classes of secondary plant
metabolites, well-known for their pronounced anticancer potential. Prenylflavonoids
from the hop plant have a great potential to trigger a change of the malignant phenotype
into a quiescent, more functionally defined form, closer to the healthy counterpart of the
same or different tissue. This approach has mainly been unexplored, opening up many
possibilities in both scientific and commercial terms. The focus of this lecture will be
on prenylflavonoid - isoxanthohumol in the context of possible melanoma therapy and
the creation of protocols that would increase the effectiveness of existing conventional
chemotherapy.",

AB  - The human body contains 60–70% water, depending on age. As a body fluid, it is not
only a medium in which physical and chemical processes take place, but it is also one of the active
mediators. Water is the richest substance with non-covalent hydrogen bonds. Water molecules, by
themselves (in vacuum), are diamagnetic but when organized into clusters, they become diamagnetic
or paramagnetic. Also, biomolecules (DNA, collagen, clathrin, and other proteins) have non-covalent
hydrogen bonds in their structure. The interaction, as well as signal transmission, between water
and biomolecules is achieved through the vibrations of covalent and non-covalent hydrogen bonds,
which determine the state and dynamics of conformational changes in biomolecules. Disruptive
conformational changes in biomolecules, cells, and tissues lead to their dysfunctionality, so they are a
frequent cause of many disorders and diseases. For example, the rearrangement of hydrogen bonding
due to mitochondrial disease mutation in cytochrome bc1 disturbs heme bH redox potential and spin
state. In order to prevent and repair the dysfunctional conformational changes, a liquid substance
was developed based on the second derivative of the C60 molecule (SD-C60), which has classical and
quantum properties. The characterization of SD-C60 by UV-VIS-NIR, FTIR, TEM, and AFM/MFM
was performed and it is shown that SD-C60 water layers generate vibrations with near-zero phase
dispersion which are transmitted through Fibonacci’s water chains to biomolecules. In comparison
with previously published SD-C60 derivate (3HFWC, size until 10 nm, and 1–5 water layers), the
improved formulation (3HFWC-W, size 10–25 nm, and 6–9 water layers) showed multiplied cytotoxic
activity against melanoma cell lines of different aggressiveness. Apart from this, the mode of action
was preserved and based on an induction of senescence rather than cell death. Importantly, high
selectivity towards malignant phenotypes was detected. Observed effects can be ascribed to a
machinery of hydrogen bonds, which are generated in SD-C60 and transmitted through water to
biomolecules. This approach may open a new field in science and healthcare—a “water-based
nanomedicine”.

AB  - Background: Shikonins are naturally occurring naphthoquinones found in the roots of several genera of the Boraginaceae family, widely known for their antiinflammatory, antioxidant, antimicrobial, and anticancer properties. This study aimed to investigate the antitumor potential of six shikonins isolated from the roots of Onosma visianii against highly aggressive rat glioma cell line C6 and to explore the mechanisms involved. Material and Methods: Cell viability was estimated by MTT and CV assays. Cell death, proliferation rate, and caspase activity were assessed using flow cytometric analysis of annexin V-FITC/propidium iodide, CFSE, and ApoStat staining, respectively. Fluorescent microscopy of propidium iodide-stained cells was employed for the detection of nuclear morphology. To evaluate the viability of detached cells, an acidic phosphatase assay was used. The cells’ property to adhere was assessed by cell adhesion assay while western blot was engaged to measure the expression of relevant proteins responsible for the observed phenomenon. Results and Conclusions: All examined shikonins dose-dependently decreased the viability of C6 cells, with compounds 5 and 6 being the most potent ones. Compound 5 had a more profound effect on the proliferation rate of C6 cells than compound 6, resulting in almost 70% of inhibition of cell division. Additionally, compound 5, but not compound 6 generated a significant number of early and late apoptotic cells in treated cultures as detected by flow cytometry. In collision with this, typical morphological signs of apoptotic cells were not observed, and fluorescent microscopy revealed only the presence of enlarged nuclei. This paradox was resolved by the discovery of massive detached cell presence, indicating that glioma cells underwent anoikis, a cell attachment-dependent programmed cell death, in response to treatment with both agents. Decreased ability of C6 cells to adhere to the extracellular matrix and compromised integrin signaling was further confirmed by adhesion assay and western blot, respectively. Interestingly, while compound 5 triggered caspase-mediated anoikis, compound 6 realized anoikis in a caspase-independent manner and under sustained ERK1/2 activation, indicating the deviation from standard proanoikis signaling. This study represents the first proof of shikonin derivatives’ strong anticancer potential realized through the induction of anoikis of highly proliferative and invasive malignant glioma cells.

morphology together with the loss of dividing potential upon exposure to both shikonins
implied reprogramming of the B16 cell phenotype. The absence of melanogenesis
enhancement coupled with an elevated level of myelin basic protein in response to
treatment with both tested agents suggested that the cells transdifferentiated into a
Schwann-like phenotype, with possible involvement of the autophagic process in this
conversion. Differentiation of malignant cells has become favourable in cancer treatment,
bearing in mind the phenomenon of apoptosis-induced proliferation. Hence, the specific
antitumor mode of action of shikonin derivatives on melanoma in vitro shown here
provides a good platform for new investigations of these promising natural compounds.

Moreover, upon applying moMSCORS in an  in vivo  full-thickness wound model in the syngeneic C57BL/6 mice, the treated wounds displayed different morphology to that of the untreated wound beds. Quantitative evaluation of angiogenesis, granulation and wound closure involving clinical scoring and software-based quantification indicated a lower degree of inflammation in the treated wounds. Histological staining of treated wounds by the means of H&E, Alcian Blue, PicroSirius Red and αSMA immune labelling showed lower cellularity, less collagen filaments as well as thinner dermal and epidermal layers compared with the untreated wounds, indicating a general reduction of hypertrophic scars. The decreased inflammation, accelerated wound closure and non-hypertrophic scarring, which were facilitated by moMSCORS, hereby address a common problem of hypertrophic scars and non-physiological tissue properties upon wound closure, and additionally offer an  in  vivo  model  for  the  autologous  cell-based  wound  healing.

AB  - Xanthohumol (XN) and isoxanthohumol (IXN), prenylated flavonoids from Humulus lupulus, have been shown to possess antitumor/cancerprotective, antioxidant, antiinflammatory, and antiangiogenic properties. In this study, mesoporous silica (SBA-15) was loaded with different amounts of xanthohumol and isoxanthohumol and characterized by standard analytical methods. The anticancer potential of XN and IXN loaded into SBA-15 has been evaluated against malignant mouse melanoma B16F10 cells. When these cells were treated with SBA-15 containing xanthohumol, an increase of the activity correlated with a higher immobilization rate of XN was observed. Considering the amount of XN loaded into SBA-15 (calculated from TGA), an improved antitumor potential of XN was observed (IC50 = 10.8 ± 0.4 and 11.8 ± 0.5 µM for SBA-15|XN2 and SBA-15|XN3, respectively; vs. IC50 = 18.5 ± 1.5 µM for free XN). The main mechanism against tumor cells of immobilized XN includes inhibition of proliferation and autophagic cell death. The MC50 values for SBA-15 loaded with isoxanthohumol were over 300 µg/mL in all cases investigated.

AB  - (1) Background: Their unique structure and electron deficiency have brought fullerenes
into the focus of research in many fields, including medicine. The hyper-harmonized hydroxylated
fullerene water complex (3HFWC) formulation has solved the limitations of the poor solubility
and bioavailability of fullerenes. To achieve better antitumor activity, 3HFWC was combined with
short-term irradiation of cells with hyperpolarized light (HPL) generated by the application of a
nanophotonic fullerene filter in a Bioptron® device. The benefits of HPL were confirmed in the
microcirculation, wound healing and immunological function. (2) Methods: B16, B16-F10 and A375
melanoma cells were exposed to a wide spectrum of 3HFWC doses and to a single short-term HPL
irradiation. (3) Results: Apart from the differences in the redox status and level of invasiveness, the
effects of the treatments were quite similar. Decreased viability, morphological alteration, signs of
melanocytic differentiation and cellular senescence were observed upon the successful internalization
of the nanoquantum substance. (4) Conclusions: Overall, 3HFWC/HPL promoted melanoma cell
reprogramming toward a normal phenotype.

AB  - Fullerene C60 is the third allotropic modification of carbon in nature. Exceptional physical and
structural features of C60 molecule make it attractive for biomedical research in a wide spectrum of
applications from imaging, drug delivery, to therapy of different disorders. However, its low
solubility in water or polar solvents, and genotoxic potential represent serious barriers for its usage.
To overcome mentioned limits the second derivative of fullerene C60 (Hyper harmonized
hydroxylated fullerene water complex - 3HFWC) is created through functionalization of the first
fullerene C60 derivative (fullerol - C60(OH)x) by the addition of paired OH groups in water layers
surrounding the solid phase of substance. The solid phase consists of the C60 molecule, covalent OH
groups and 3-6 water layers with strong hydrogen bonds. The liquid phase consists of additional
water layers bonded by moderate to weak hydrogen bonds. In addition, the third derivative of
fullerene is made when 3HFWC was integrated with nano-gold particles (nAu@3HFWC). The aim
of this study was to evaluate fullerene C60 derivatives uptake and their intracellular distribution in
mouse 3T3 fibroblasts. Cells were exposed to 30 μg/ml C60(OH)x, or 30 μg/ml 3HFWC, or 5μg/ml
nAu@3HFWC during 30 min, 1h or 2h and analysis was done by Philips FEI CM12 transmission
electron microscope. Ultrastructural analysis showed mainly cytoplasmic localization of C60(OH)x
and its derivatives, and also a sporadic presence in mitochondria and nuclei. The concentration of
fullerene derivatives in these cells was time-dependent, i.e., more concentration was observed in
cells with longer exposition to these fullerenes. Furthermore, C60(OH)x is also localized in lysosomes
in higher concentrations. These results suggest that novel C60 fullerene derivatives show better
biocompatibility in mouse 3T3 fibroblasts compared to C60(OH)x, which mainly ends in lysosomes,
the waste disposal system of the cell.

AB  - Tubulisins are natural peptide compounds isolated from mycobacterial genera.
They belong to the group of antimitotic agents, since they achieve their antitumor
effect disrupting the function of mitotic spindle. The object of this study was to investigate
anticancer potential of synthetic analogue of tubulysins, tubugi 1, on mouse
melanoma model, in vitro and in vivo. Tubugi 1 decreased dose-dependently viability
of B16 cells. The experimental compound induced atypical apoptosis without the externalization
of phosphatidylserines (PS). Although apoptosis was accompanied with
strong intracellular production of reactive oxygen and nitrogen species, decrease in
malonyldyaldehyde content showed that membrane lipids were not subjected to oxidation,
what is a prerequisite for the externalization of PS. Although PS plays a key
role in the removal of apoptotic cells, this did not affect the phagocytic activity of
macrophages in vitro, implying PS-independent apoptotic cells removal. The effect of
the experimental agent was confirmed in vivo. Мacrophages isolated from peritoneal
exudate of treated animals showed cytotoxic activity, what was in line with demonstrated
expression of M1 phenotype markers, as well as production of nitric oxide.
Additonally, the phagocytic activity of these cells was preserved. Having in mind lack
of data in the literature concerning the effects of this group of agents on components
of the innate immune system, tubugi 1 remains worthy of further research in the field
of experimental oncology.

AB  - A prenylflavonoid from hops, isoxanthohumol (IXN) is gaining a lot of attention
nowadays due to its broad spectrum of biological activities. This study aimed to investigate
its potential antimetastatic properties in vitro against the highly invasive melanoma
cell line B16-F10 and in a murine metastatic model in vivo, in the context of
independent action and interaction with chemotherapy. The treatment with IXN diminished
cell viability in a dose-dependent manner, which is a consequence of induced
combined cell death by autophagy and caspase-dependent apoptosis. Additionally, the
dividing potential of highly proliferative melanoma cells was dramatically affected by
IXN, and is in line with an abrogated clonogenic potential in the population of survived
cells, indicating changes in their metastatic features. Concordantly, IXN strongly diminished
cell metastatic features down-regulating adhesion, migration, and invasion
through disrupted integrin signaling. Separate application of IXN inhibited the development
of lung metastatic foci in tumor-challenged animals. Although IXN potentiated
the action of chemotherapeutic drug paclitaxel (PCT) in vitro, the concomitant
treatment of these two agents did not exert statistically significant suppression of lung
metastases formation. Nonetheless, the change in the regime of drugs’ application to
7-day treatment with IXN prior to PCT made the subtherapeutic dose of PCT effective,
indicating IXNs’ capacity to trigger the differentiation of B16-F10 cells toward a less
invasive phenotype, thus sensitizing them to chemotherapy. Along with histopathological
confirmation of changes in cell phenotype in metastases, this data underlines the
important impact of the differentiation process on chemotherapy efficacy. This study
represents the first proof of IXNs’ antimetastatic activity in vivo and significantly contributes
to the development of the differentiation therapy concept as a support in the
treatment of metastatic malignancies.

AB  - Prenylflavonoid from hops - xanthohumol (XN) has been shown to possess diverse biological properties, including strong anticancer activity. One of the possibilities for improving delivery and effectiveness of drugs is the use of mesoporous silica nanoparticles such as nontoxic SBA-15. The aim of this study was the evaluation of the in vitro anticancer potential of XN loaded with different amounts into SBA-15 particles against malignant mouse melanoma B16-F10 cells. Our data indicate that SBA-15 containing XN showed a loading rate–activity dependence. Importantly, immobilization of XN into SBA-15 preserved and even potentiated its antitumor potential, in comparison to its free form. Also, by loading into SBA-15 carrier, XNs’ anticancer mode of action converted from predominantly cytotoxic to cytostatic, resulting in a reduction of dividing potential. In addition, contrasting the previously observed apoptotic-inducing property of free XN, immobilized XN induced autophagic cell death that might be important for disabling tumor repopulation in response to apoptotic-induced cell proliferation, a mechanism often asscociated with therapy failure of advanced forms of cancer1.

AB  - Izoksantohumol (IXN), prenilflavonoid iz hmelja, poseduje spektar bioloških aktivnosti značajnih za tretman brojnih patoloških stanja. U ovoj studiji ispitivan je njegov uticaj na modelima solidnog i metastatskog melanoma in vitro i in vivo, u kontekstu samostalnog delovanja na ćelije melanoma različite agresivnosti i interakcije sa hemioterapijom. Pokazano je da su efekti IXN bili postojani na svim ćelijskim linijama melanoma ‒ od nisko invazivne forme B16 poreklom iz miša, preko visoko invazivne linije humanog porekla A-375, do metastatskog klona B16-F10. Pored inhibicije proliferacije uočene na svim linijama, tretman IXN doveo je do diferencijacije i gubitka pluripotentnih svojstava B16 i A-375 ćelija, uz prisustvo apoptoze i značajne promene u signalnim putevima relevantnim za ove procese. Sa druge strane, IXN je uz indukciju programirane ćelijske smrti tipa I i II na klonu B16-F10, smanjio klonogeni potencijal populacije preživelih ćelija i, narušavajući integrinsku signalizaciju, redukovao adhezivnost, migratornost i invazivnost. Pored jasnog trenda u supresiji solidnog, a posebno metastatskog melanoma, IXN je potencirao delovanje paklitaksela (PCT) in vitro i in vivo. Za razliku od paralelnog tretmana, aplikovanje IXN 7 sukcesivnih dana pre početka hemioterapije učinilo je efikasnom subterapeutsku dozu PCT u modelu singenog metastatskog melanoma. Ovaj podatak je, uz histopatološku potvrdu promene fenotipa ćelija u metastazama, podvukao važnost indukcije diferencijacije u kasnijem učinku hemioterapije. Opisani rezultati predstavljaju prvi dokaz antitumorske aktivnosti IXN in vivo, kao i značajan doprinos novom konceptu diferencijacione terapije u lečenju solidnih i metastatskih maligniteta.
AB  - Isoxanthohumol (IXN), a prenylflavonoid from hops, owns a spectrum of biological activities important for the therapy of numerous pathological conditions. In this study, its influence on solid and metastatic melanoma models in vitro and in vivo was investigated, in the context of independent action on melanoma cells of different aggressiveness and interaction with chemotherapy. The effects of IXN were consistent in all cell lines ‒ from the low-invasive mouse-derived B16 form and highly invasive line of human origin A-375 to metastatic clone B16-F10. In addition to proliferation inhibition observed in all cell lines, IXN treatment led to differentiation and loss of pluripotent properties of B16 and A-375 cells, with the presence of apoptosis and significant changes in signaling pathways relevant to these processes. On the other hand, along with induction of apoptosis and autophagy in B16-F10 clones, IXN decreased the clonogenic potential in the population of surviving cells and, by disrupting integrin signaling, reduced adhesion, migration and, invasiveness. Aside from a clear trend in the suppression of solid and metastatic melanoma, IXN potentiated the action of paclitaxel (PCT) in vitro and in vivo. Unlike concomitant treatment, the 7-days application of IXN before the start of chemotherapy made the subtherapeutic dose of PCT effective in the metastatic melanoma model. This data, along with histopathological confirmation of changes in cells’ phenotype in metastases, underlined the importance of induction of differentiation for chemotherapy outcome. The described results represent the first proof of IXN antitumor activity in vivo, as well as a significant contribution to a new concept of differentiation therapy in the treatment of solid and metastatic malignancies.

abstract = "Izoksantohumol (IXN), prenilflavonoid iz hmelja, poseduje spektar bioloških aktivnosti značajnih za tretman brojnih patoloških stanja. U ovoj studiji ispitivan je njegov uticaj na modelima solidnog i metastatskog melanoma in vitro i in vivo, u kontekstu samostalnog delovanja na ćelije melanoma različite agresivnosti i interakcije sa hemioterapijom. Pokazano je da su efekti IXN bili postojani na svim ćelijskim linijama melanoma ‒ od nisko invazivne forme B16 poreklom iz miša, preko visoko invazivne linije humanog porekla A-375, do metastatskog klona B16-F10. Pored inhibicije proliferacije uočene na svim linijama, tretman IXN doveo je do diferencijacije i gubitka pluripotentnih svojstava B16 i A-375 ćelija, uz prisustvo apoptoze i značajne promene u signalnim putevima relevantnim za ove procese. Sa druge strane, IXN je uz indukciju programirane ćelijske smrti tipa I i II na klonu B16-F10, smanjio klonogeni potencijal populacije preživelih ćelija i, narušavajući integrinsku signalizaciju, redukovao adhezivnost, migratornost i invazivnost. Pored jasnog trenda u supresiji solidnog, a posebno metastatskog melanoma, IXN je potencirao delovanje paklitaksela (PCT) in vitro i in vivo. Za razliku od paralelnog tretmana, aplikovanje IXN 7 sukcesivnih dana pre početka hemioterapije učinilo je efikasnom subterapeutsku dozu PCT u modelu singenog metastatskog melanoma. Ovaj podatak je, uz histopatološku potvrdu promene fenotipa ćelija u metastazama, podvukao važnost indukcije diferencijacije u kasnijem učinku hemioterapije. Opisani rezultati predstavljaju prvi dokaz antitumorske aktivnosti IXN in vivo, kao i značajan doprinos novom konceptu diferencijacione terapije u lečenju solidnih i metastatskih maligniteta., Isoxanthohumol (IXN), a prenylflavonoid from hops, owns a spectrum of biological activities important for the therapy of numerous pathological conditions. In this study, its influence on solid and metastatic melanoma models in vitro and in vivo was investigated, in the context of independent action on melanoma cells of different aggressiveness and interaction with chemotherapy. The effects of IXN were consistent in all cell lines ‒ from the low-invasive mouse-derived B16 form and highly invasive line of human origin A-375 to metastatic clone B16-F10. In addition to proliferation inhibition observed in all cell lines, IXN treatment led to differentiation and loss of pluripotent properties of B16 and A-375 cells, with the presence of apoptosis and significant changes in signaling pathways relevant to these processes. On the other hand, along with induction of apoptosis and autophagy in B16-F10 clones, IXN decreased the clonogenic potential in the population of surviving cells and, by disrupting integrin signaling, reduced adhesion, migration and, invasiveness. Aside from a clear trend in the suppression of solid and metastatic melanoma, IXN potentiated the action of paclitaxel (PCT) in vitro and in vivo. Unlike concomitant treatment, the 7-days application of IXN before the start of chemotherapy made the subtherapeutic dose of PCT effective in the metastatic melanoma model. This data, along with histopathological confirmation of changes in cells’ phenotype in metastases, underlined the importance of induction of differentiation for chemotherapy outcome. The described results represent the first proof of IXN antitumor activity in vivo, as well as a significant contribution to a new concept of differentiation therapy in the treatment of solid and metastatic malignancies.",

AB  - The main focus of this study is exploring the effect and mechanism of two HIV-protease inhibitors: Ritonavir and Ritonavir-nitric oxide (Ritonavir-NO) on in vitro growth of melanoma cell lines. NO modification significantly improved the antitumor potential of Ritonavir, as the IC50 values of Ritonavir-NO were approximately two times lower than IC50 values of the parental compound. Our results showed for the first time, that both compounds induced senescence in primary and metastatic melanoma cell lines. This transformation was manifested as a change in cell morphology, enlargement of nuclei, increased cellular granulation, upregulation of β-galactosidase activity, lipofuscin granules appearance, higher production of reactive oxygen species and persistent inhibition of proliferation. The expression of p53, as one of the key regulators of senescence, was upregulated after 48 hours of Ritonavir-NO treatment only in metastatic B16F10 cells, ranking it as a late-response event. The development of senescent phenotype was consistent with the alteration of the cytoskeleton-as we observed diminished expression of vinculin, α-actin, and β-tubulin. Permanent inhibition of S6 protein by Ritonavir-NO, but not Ritonavir, could be responsible for a stronger antiproliferative potential of the NO-modified compound. Taken together, induction of senescent phenotype may provide an excellent platform for developing therapeutic approaches based on selective killing of senescent cells.

AB  - BACKGROUND/AIM Tubugi-1 is a more stable and accessible synthetic counterpart of natural tubulysins. This study aimed to evaluate its cytotoxic potential against anaplastic human melanoma cells. MATERIALS AND METHODS The viability of A-375 cells was determined by 3-(4,5-dimethythiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and crystal violet assay. The type of cell death and proliferative rate were investigated using flow cytometry and fluorescent microscopy, while the molecular background was evaluated by western blot. RESULTS Tubugi-1 reduced the viability of A-375 cells, inducing massive micronucleation, followed by augmented expression of inhibitor of nuclear factor-κB and caspase-2, typical of a mitotic catastrophe. Disturbed proliferation and G2M block with prominent caspase activity, weakened the expression of B-cell lymphoma 2 and B-cell lymphoma 2-associated X transient up-regulation, coexisted with intensive autophagy. Specific inhibition of autophagy by chloroquine resulted in conversion from mitotic catastrophe to rapid apoptosis. CONCLUSION Multilevel anticancer action of tubugi-1 is extended by co-application of an autophagy inhibitor, giving a new dimension in further preclinical advancement of this potential agent.

AB  - The biological quality and chemical composition of alloys used in dental practice change during heat treatment. Often the residues of the previous cast are not disposed of but are reused and recycled until consumed. Thus, manufactured dental restorations have modified biological quality and chemical composition, and compromised biocompatibility. The aim of this study was to investigate the influence of repeated casting on the cytotoxicity of the silver-palladium (Ag-Pd) alloy. Our results showed that repeated casting of the Ag-Pd dental alloy affected its biocompatibility by promoting toxicity against transformed fibroblasts in a contact-independent manner. A strong decrease in cell proliferation, induction of senescence and massive cell death were observed in cultures exposed only to a medium previously incubated with dental alloy samples. The obtained data indicated that toxicity mediated by the accumulation of the Ag, Pd, Cu and Zn cations released from the Ag-Pd material was enhanced by recasting. The induction of cell senescence and subsequent apoptotic and necrotic death were accompanied by amplified intracellular production of reactive oxygen and nitrogen species, suggesting their involvement in the cell destruction process. Therefore, compromised biocompatibility after recasting with the Ag-Pd alloy can be the cause of serious local cell destruction, as observed in clinical practice

AB  - Synthetic tubugis are equally potent but more stable than their natural forms. Their anticancer potential was estimated on a solid melanoma in vitro and in vivo. Tubugi-1 induced the apoptosis in B16 cells accompanied with strong intracellular production of reactive species, subsequently imposing glutathione and thiol group depletion. Paradoxically, membrane lipids were excluded from the cascade of intracellular oxidation, according to malondialdehyde decrease. Although morphologically apoptosis was typical, externalization of phosphatidylserine (PS) as an early apoptotic event was not detected. Even their exposition is pivotal for apoptotic cell eradication, primary macrophages successfully eliminated PS-deficient tubugi-1 induced apoptotic cells. The tumor volume in animals exposed to the drug in therapeutic mode was reduced in comparison to control as well as to paclitaxel-treated animals. Importantly, macrophages isolated from tubugi-1 treated animals possessed conserved phagocytic activity and were functionally and phenotypically recognized as M1. The cytotoxic effect of tubugi-1 is accomplished through its ability to polarize the macrophages toward M1, probably by PS independent apoptotic cell engulfment. The unique potential of tubugi-1 to prime the innate immune response through the induction of a specific pattern of tumor cell apoptosis can be of extraordinary importance from fundamental and applicable aspects.

Tubugi-1 induced the apoptosis in B16 cells accompanied with strong intracellular production of reactive species, subsequently imposing glutathione and thiol group depletion. Paradoxically, membrane lipids were excluded from the cascade of intracellular oxidation, according to malondialdehyde decrease.

AB  - Isoxanthohumol (IXN), a prenylflavonoid from hops and beer, gained increasing attention as a potential chemopreventive agent. In the present study, IXN antimetastatic potential in vitro against the highly invasive melanoma cell line B16-F10 and in vivo in a murine metastatic model was investigated. Melanoma cell viability was diminished in a dose-dependent manner following the treatment with IXN. This decrease was a consequence of autophagy and caspase-dependent apoptosis. Additionally, the dividing potential of highly proliferative melanoma cells was dramatically affected by this isoflavanone, which was in correlation with an abrogated cell colony forming potential, indicating changes in their metastatic features. Concordantly, IXN promoted strong suppression of the processes that define metastasis- cell adhesion, invasion, and migration. Further investigation at the molecular level revealed that the abolished metastatic potential of a melanoma subclone was due to disrupted integrin signaling. Importantly, these results were reaffirmed in vivo where IXN inhibited the development of lung metastatic foci in tumor-challenged animals. The results of the present study may highlight the beneficial effects of IXN on melanoma as the most aggressive type of skin cancer and will hopefully shed a light on the possible use of this prenylflavonoid in the treatment of metastatic malignancies.

AB  - In this study mesoporous silica SBA-15 was evaluated as a vehicle for the transport of cytotoxic natural product emodin (EO). SBA-15 was loaded with different quantities of EO (SBA-15|EO1⁻SBA-15|EO5: 8⁻36%) and characterized by traditional methods. Several parameters (stabilities) and the in vitro behavior on tumor cell lines (melanoma A375, B16 and B16F10) were investigated. SBA-15 suppresses EO release in extremely acidic milieu, pointing out that EO will not be discharged in the stomach. Furthermore, SBA-15 protects EO from photodecomposition. In vitro studies showed a dose dependent decrease of cellular viability which is directly correlated with an increasing amount of EO in SBA-15 for up to 27% of EO, while a constant activity for 32% and 36% of EO in SBA-15 was observed. Additionally, SBA-15 loaded with EO (SBA-15|EO3) does not disturb viability of peritoneal macrophages. SBA-15|EO3 causes inhibition of tumor cell proliferation and triggers apoptosis, connected with caspase activation, upregulation of Bax, as well as Bcl-2 and Bim downregulation along with amplification of poly-(ADP-ribose)-polymerase (PARP) cleavage fragment. Thus, the mesoporous SBA-15 is a promising carrier of the water-insoluble drug emodin.

AB  - Glioblastoma (GBM) is the most frequent and deadly form of primary malignant brain tumor among adults. A promising emerging approach for GBM treatment may be offered from HIV protease inhibitors (HIV-PIs). In fact, in addition to their primary pharmacological activity in the treatment of HIV infection, they possess important anti-neoplastic effects. According to previous studies, the addition of a nitric oxide (NO) donating group to parental compounds can reduce their toxicity and enhance the anticancer action of various compounds, including HIV-PIs. In this study we compared the effects of the HIV-PI Lopinavir (Lopi) and of its NO-derivative Lopinavir-NO (Lopi-NO) on the in vitro growth of LN-229 and U-251 human GBM cell lines. Lopi-NO reduced the viability of LN-229 and U-251 cells at significantly lower concentrations than the parental drug. In particular, Lopi-NO inhibited tumor cell proliferation and induced the differentiation of U-251 cells toward an astrocyte-like phenotype without triggering significant cell death in both cell types. The anticancer effect of Lopi-NO was persistent even upon drug removal. Furthermore, Lopi-NO induced strong autophagy that did not appear to be related to its chemotherapeutic action. Overall, our results suggest that Lopi-NO could be a potential effective anticancer drug for GBM treatment.

AB  - Synthesis of platinum(II) conjugate with acetylated betulinic acid tris(hydroxymethyl)aminomethane ester (BATRIS) is presented (BATRISPt). HR-ESI-MS and multinuclear NMR spectroscopy, as well as elemental analysis were used for characterization of BATRISPt. Cytotoxicity (3-(4,5-dimethythiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), crystal violet (CV), and sulforhodamine B (SRB) assays) of BA, BATRIS, BATRISPt, and cisplatin were assessed on seven different tumor cell lines: melanoma B16, colon HCT116 and DLD-1, adenocarcinoma HeLa, breast MCF-7, and anaplastic thyroid tumor 8505C and SW1736; as well as normal MRC-5 fibroblasts. Furthermore, the effect of the mentioned compounds on the apoptosis (Annexin V/PI assay) and autophagy induction (acridine orange (AO) assay) as well as caspase 3, 8, and 9 activation were investigated on the selected B16 melanoma cell line. BATRISPt showed lower activity than BA, BATRIS, or cisplatin. All tested compounds triggered apoptosis in B16 cells. Induction of autophagy was observed in B16 cells exposed only to BATRIS. On the other hand, new conjugate activates caspases 8 and 9 in B16 cells with higher impact than BATRIS or cisplatin alone.
