AB  - While the effect of gut microbiota and/or inflammation on a distant body site, including the lungs (gut–lung axis), has been well characterized, data about the influence of lung microbiota and lung inflammation on gut homeostasis (lung–gut axis) are scarce. Using a well-characterized model of pulmonary infection with the fungus Aspergillus fumigatus, we investigated alterations in the lung and gut microbiota by next-generation sequencing of the V3–V4 regions of total bacterial DNA. Pulmonary inflammation due to the fungus A. fumigatus caused bacterial dysbiosis in both lungs and gut, but with different characteristics. While increased alpha diversity and unchanged bacterial composition were noted in the lungs, dysbiosis in the gut was characterized by decreased alpha diversity indices and modified bacterial composition. The altered homeostasis in the lungs allows the immigration of new bacterial species of which 41.8% were found in the feces, indicating that some degree of bacterial migration from the gut to the lungs occurs. On the contrary, the dysbiosis occurring in the gut during pulmonary infection was a consequence of the local activity of the immune system. In addition, the alteration of gut microbiota in response to pulmonary infection depends on the bacterial composition before infection, as no changes in gut bacterial microbiota were detected in a rat strain with diverse gut bacteria. The data presented support the existence of the lung–gut axis and provide additional insight into this mechanism.

AB  - Mitohondrijska DNK (mtDNK) se odlikuje nizom osobina koje je čine pogodnom za istraživanja evolutivne
istorije ljudskih populacija koja se zasniva na molekularnim markerima ženske linije nasleđivanja. Tokom
poslednje decenije publikovano je više naučnih radova u kojima je analizirana varijabilnost mtDNK u populaciji Srbije primenom markera različite rezolucije uključujući i kompletne genome. U skladu sa očekivanjima zasnovanim na istorijskim, arheološkim i drugim izvorima koji govore u prilog veoma kompleksne istorije populacija na Balkanskom poluostrvu, mtDNK podaci su potvrdili da se srpska populacija odlikuje visokim nivoom raznovrsnosti mtDNK koji je posledica izuzetno složene dinamike ove populacije tokom vremena. Današnji mtDNK profil populacije Srbije ne odstupa od matrilinealnog profila karakterističnog za druge evropske populacije, a genetičke distance pokazuju da ova populacija zauzima centralnu poziciju unutar grupe južnoslovenskih populacija koje se odlikuju visokom heterogenošću. Srpska populacija deli najveći procenat mtDNK haplotipova sa geografski bliskim populacijama Balkanskog poluostrva koje pripadaju južnoslovenskoj grupi, gde su uočeni i potencijalno privatni haplotipovi. Na osnovu filogenetske i filogeografske analize kompletnih mitogenoma u srpskoj populaciji detektovane su retke mtDNK linije,karakteristične za druge regione, poput Bliskog istoka (N1b, HV2), istočne Azije (D4) i Afrike (L2a1), kao i one koje su potencijalno specifične za Balkansko poluostrvo, poput K1a13a1, U4c1b1 i H6a2b. Pored toga, srpska populacija deli određeni broj mtDNK podhaplogrupa sa istočno- i zapadnoslovenskim populacijama kao i sa germanskim populacijama severne i srednje Evrope. Istraživanja varijabilnosti mtDNK su pokazala da se izuzetno velika raznovrsnost mtDNK savremene populacije Srbije može objasniti genetičkim doprinosom kako slovenskih i germanskih, tako i pre-slovenskih populacija koje su naseljavale Balkansko poluostrvo pre Velike seobe naroda.
AB  - The mitochondrial DNA (mtDNA) is characterized by a number of features that make it suitable for study-
ing the evolutionary history of human populations based on molecular markers with the female-specific
line of inheritance. During the last decade, several scientific papers were published in which the mtDNA
variability in the population of Serbia was analyzed using markers of different resolution including com-
plete mitogenomes. In accordance with expectations based on historical, archaeological and other sources
that speak in favor of a very complex history of populations on the Balkan Peninsula, mtDNA data con-
firmed that Serbian population is characterized by a high level of mtDNA diversity, which is a consequence
of the exceptionally complex dynamics of this population over time. Today’s mtDNA profile of the Serbian
population does not differ from the matrilineal landscape characteristic of other European populations,
and according to genetic distances, this population occupies a central position within the group of South-
Slavic populations characterized by high heterogeneity. The Serbian population shares the highest per-
centage of mtDNA haplotypes with the geographically close populations of the Balkan Peninsula
belonging to the South-Slavic group, where potentially private haplotypes were also observed. Phyloge-
netic and phylogeographic analysis of complete mitogenomes in the Serbian population revealed rare
mtDNA lines, characteristic of other regions, such as the Middle East (N1b, HV2), East Asia (D4) and Africa
(L2a1), as well as those that are potentially specific for Balkan Peninsula, like K1a13a1, U4c1b1 and H6a2b.
In addition, Serbian population shares a certain number of mtDNA subhaplogroups with East- and West-
Slavic populations as well as with the Germanic populations of Northern and Central Europe. Studies of
mtDNA variability have shown that the exceptionally high mtDNA diversity in contemporary Serbian pop-
ulation may be associated with the genetic contribution of both Slavic and Germanic, as well as pre-Slavic
populations that inhabited the Balkan Peninsula before the Great Migration.

sistemom i gastrointestinalnim traktom. Toksične supstance ostvaruju direktan štetni efekat na sastav

EPS-AN8 na ublažavanje takvih štetnih efekata.

GST). Oralni unos EPS-AN8 je značajno ublažio sve navedene promene. Oralna izloženost kadmijumu
uzrokuje nedvosmislene promene u sastavu mikrobiote, koje mogu biti praćene i pojačanim nivoima

AB  - The gut microbiota has important role in maintaining homeostasis via its effect on the immune system
and healthy gastrointestinal tract. Environmental toxicants directly influenced the changes in gut microbiota
composition. Cadmium (Cd) is a hazard, world widely distributed metal. We have proposed
the putative mechanism of protection against Cd harmful effect in the organism by using exopolysaccharides
derived from Lactiplantibacillus plantarum BGAN8 (EPS-AN8) which has great ability to sequester Cd ions.
Aims of our study were to examine Cd related changes in the gut microbiota of Dark agouti (DA) rats after
prolonged oral exposure (30 days) to this metal and to determine impact of EPS-AN8 in preventing
those changes.
Rats were given via water lower (5 ppm) and higher (50 ppm) Cd’s dose. In paralel, EPS-AN8 was administrated
through food (100 μg/ml). Total DNA from duodenum was isolated and PCR amplicon for 16SrRNA was
sequenced on Illumina NovaSeq paired end platform. Moreover, we have followed changes in
oxidative stress and inflammation in duodenum. Cd favored growth of opportunistic pathogen bacteria
genera (Blautia, Prevotella, Alloprevotela, Bacteroides) while the relative abundance of lactobacilli was
decreased. The both doses of Cd increased production of inflammatory cytokines (IL-1β, TNF-α, and
IFN-γ). Also, parameters of oxidative stress were significantly upregulated (MDA, CAT, and GST).
All the mentioned changes were alleviated by EPS-AN8. Oral exposure to Cd lead to inevitable changes
in the microbiota structure followed by inflammation and oxidative stress of surrounding tissue, while
administration of EPS-AN8 reversed those changes.

Hence, the impact of sugars and their substitutes used in diet on the development of virulence in Pseudomonas aeruginosa PAO1 was investigated. Sugars (fructose, demerara, coconut sugar, and cane sugar) and sugar substitutes (erythritol and stevia) were selected. The genes from three P. aeruginosa QS networks (las - lasI, lasR; rhl - rhlI, rhlR; PQS - pqsA, mvfR) were used for RT-qPCR analysis in order to investigate whether the expression of these genes changes. In this work, the focus is on the expression of genes involved in QS and the ability to form biofilms (a type of structured community of microorganisms that is attached to the surface and connected by an exopolysaccharide matrix), as well as determining minimal inhibitory concentration of antibiotics in presence of tested compounds.
Methods: Microdiltuion assay, Antibiofilm assay, RT- qPCR
Results: In the presence of tested sugars and their substitutes, the minimum inhibitory concentration of commercial antibiotics increased, as well as the percentages of biofilm formation (for instance, the percentage of biofilm formation is 171% in the presence of coconut sugar). Furthermore, exposure of P. aeruginosa to tested compounds caused the greatest increase in expression of virulence associated with the lasI and pvdF genes.
Conclusion: More awareness and research is needed to highlight the effects sugars can have on P. aeruginosa and to propose new strategies to reduce this negative aspect.

AB  - Since the realization that the lungs are not sterile but are normally inhabited by various bacterial species, studies have been conducted to define healthy lung microbiota and to investigate whether it changes during lung diseases, infections, and inflammation. Using next-generation sequencing, we investigatedbacterial microbiota from whole lungs in two rat strains (previously shown to differ in gut microbiotacomposition) in a healthy state and during pulmonary infection caused by the opportunistic fungusAspergillus fumigatus. No differences in alpha diversity indices and microbial composition between DAand AO rats before infection were noted. Fungal infection caused dysbiosis in both rat strains, characterizedby increased alpha diversity indices and unchanged beta diversity. The relative abundance ofgenera and species was increased in DA but decreased in AO rats during infection. Changes in lungmicrobiota coincided with inflammation (in both rat strains) and oxidative stress (in DA rats). Disparateresponse of lung microbiota in DA and AO rats to pulmonary fungal infection might render these two ratstrains differentially susceptible to a subsequent inflammatory insult.

AB  - Introduction: Cigarette smoke exposure is a known risk factor for development of lung diseases and
electronic cigarettes (e-cigarettes) were introduced as a popular and safer alternative to combustible tobacco products. Increasing number of studies are reporting their adverse biological effects both in vivo
and in vitro. Aim of this study was to evaluate the effect of e-cigarettes on mitochondrial function in
lung bronchial epithelial cells.
Methods: Electronic cigarette vapor condensate (ECC) was generated using an e-cigarette device on a
suction trap cooled in a dry ice/ethanol bath. We used unflavoured and flavoured e-cigarette liquids with
and without nicotine. Human bronchial epithelial BEAS2B cells were seeded in 96well plates and treated
with 2% e-cigarette vapour condensate for 24h. Mitochondrial membrane potential was measured using
50nM TMRE (Tetramethyl rhodamine ethyl ester) and cells were visualized on ImageXpress® Pico Automated Cell Imaging System (Molecular Devices, San Jose, CA, USA) with a 10x objective.
Results: We found a significant reduction of TMRE fluorescence in treated cells compared to the control. Imaging of treated cells also revealed changes in cell morphology and the presence of mitochondria in TNT-like structures.
Conclusion: Mitochondrial dysfunction has been associated with various pathological conditions including lung diseases such as asthma, COPD and lung cancer. Due to their relative novelty, the role of
electronic cigarette use in development of chronic lung diseases is still relatively unknown. Our findings
contribute to the growing list of studies pointing to their adverse biological effects and imply their involvement in processes contributing to chronic lung diseases.

AB  - Abstract

Data obtained with the use of massive parallel sequencing (MPS) can be valuable in population genetics studies. In particular, such data harbor the potential for distinguishing samples from different populations, especially from those coming from adjacent populations of common origin. Machine learning (ML) techniques seem to be especially well suited for analyzing large datasets obtained using MPS. The Slavic populations constitute about a third of the population of Europe and inhabit a large area of the continent, while being relatively closely related in population genetics terms. In this proof-of-concept study, various ML techniques were used to classify DNA samples from Slavic and non-Slavic individuals. The primary objective of this study was to empirically evaluate the feasibility of discerning the genetic provenance of individuals of Slavic descent who exhibit genetic similarity, with the overarching goal of categorizing DNA specimens derived from diverse Slavic population representatives. Raw sequencing data were pre-processed, to obtain a 1200 character-long binary vector. A total of three classifiers were used—Random Forest, Support Vector Machine (SVM), and XGBoost. The most-promising results were obtained using SVM with a linear kernel, with 99.9% accuracy and F1-scores of 0.9846–1.000 for all classes.

AB  - Objective:
The little data of the effect of pulmonary fungal infection on lung and
gut microbiota exist, thus aim of our study was to examine the effect of
Aspergillus fumigatus infection on bacterial homestasis in these organs in
Dark Agouti (DA) and Albino Oxford (AO) rats known to develop different
immune responce to the fungus.
Methods:
16S rRNA amplicon sequencing of the V3-V4 hypervariable region.
Enzyme-linked immunosorbent assay for cytokine content (IL-10, IL-6, TNF,
IL-1beta, IL-17 i IFN-gamma) in lung and gut homogenats, and plasma (IL-
6, IL-17, TNF). Myeloperoxidase, catalase, glutathione S-transferase and
content of reduced glutathione in lung homogenates.
Results:
No initial differences in lung bacterial microbiota between healthy DA
and AO rats exists, but A. fumigatus infection resulted in increase in
alpha diversity (without effect on bacterial composition) in both strains.
Changes in relative abundance at genus and species level were expressed
differently (increased in DA, decreased in AO). Dysbiosis in lung coincided
with increase of IFN-gamma, IL-17 and MPO in both strains, and increase
oxidative stress solely in DA. Gut inflammation was noted in both strains,
while bacterial dysbiosis only in DA.
Conclusions:
Pulmonary fungal infection resulted in bacterial dysbiosis in lung (in both
rat strains), and gut (solely in DA). Noted lung and gut inflammation in
these two rat strains, coexisted with different effects on bacterial
homeostasis, which could be due to different genetic background or

abstract = "Objective:
The little data of the effect of pulmonary fungal infection on lung and
gut microbiota exist, thus aim of our study was to examine the effect of
Aspergillus fumigatus infection on bacterial homestasis in these organs in
Dark Agouti (DA) and Albino Oxford (AO) rats known to develop different
immune responce to the fungus.
Methods:
16S rRNA amplicon sequencing of the V3-V4 hypervariable region.
Enzyme-linked immunosorbent assay for cytokine content (IL-10, IL-6, TNF,
IL-1beta, IL-17 i IFN-gamma) in lung and gut homogenats, and plasma (IL-
6, IL-17, TNF). Myeloperoxidase, catalase, glutathione S-transferase and
content of reduced glutathione in lung homogenates.
Results:
No initial differences in lung bacterial microbiota between healthy DA
and AO rats exists, but A. fumigatus infection resulted in increase in
alpha diversity (without effect on bacterial composition) in both strains.
Changes in relative abundance at genus and species level were expressed
differently (increased in DA, decreased in AO). Dysbiosis in lung coincided
with increase of IFN-gamma, IL-17 and MPO in both strains, and increase
oxidative stress solely in DA. Gut inflammation was noted in both strains,
while bacterial dysbiosis only in DA.
Conclusions:
Pulmonary fungal infection resulted in bacterial dysbiosis in lung (in both
rat strains), and gut (solely in DA). Noted lung and gut inflammation in
these two rat strains, coexisted with different effects on bacterial
homeostasis, which could be due to different genetic background or
bacterial composition prior infection.",

AB  - Cadmium (Cd) is a highly toxic metal that is distributed worldwide. Exposure to it is
correlated with a vast number of diseases and organism malfunctions. Exopolysaccharides (EPS)
derived from Lactiplantibacillus plantarum BGAN8, EPS-AN8, previously showed great potential for
the in vitro protection of intestinal cells from this metal. Here, we investigated the potential of food
supplemented with EPS-AN8 to protect rats from the hazardous effects of Cd exposure. After thirty
days of exposure to lower (5 ppm) and higher (50 ppm)-Cd doses, the administration of EPS-AN8 led
to decreased Cd content in the kidneys, liver, and blood compared to only Cd-treated groups, whereas
the fecal Cd content was strongly enriched. In addition, EPS-AN8 reversed Cd-provoked effects on
the most significant parameters of oxidative stress (MDA, CAT, GST, and GSH) and inflammation
(IL-1 , TNF- , and IFN-
) in the duodenum. Moreover, micrographs of the duodenum were in line
with these findings. As the gut microbiota has an important role in maintaining homeostasis, we used
16S rRNA amplicon sequencing and investigated the effects of Cd and EPS-AN8 on one part of the
microbiota presented in the duodenum. Although Cd decreased the growth of lactobacilli and mostly
favored the blooming of opportunistic pathogen bacteria, parallel intake of EPS-AN8 reversed those
changes. Therefore, our results imply that EPS-AN8 might be extremely noteworthy in combatting
this toxic environmental pollutant.

AB  - Despite the significant advances in drug development we are witnessing the inability of health systems to combat both neurodegenerative diseases and cancers, especially glioblastoma. Hence, natural products are comprehen-sively studied in order to provide novel therapeutic options. This study aimed to explore anti-neurodegenerative and anti-glioblastoma potential of extract of Phlomis fruticosa L. using in vitro model systems. It was found that the methanol extract of P. fruticosa was able to efficiently reduce activities of enzymes linked to neurodegenera-tive disease including acetylcholinesterase, butyrylcholinesterase and tyrosinase. Furthermore, P. fruticosa extract has shown excellent antioxidant potential, as evidenced by six different methods. Analysis of cytotoxic effect of P. fruticosa extract on A172 glioblastoma cell line revealed that the concentration of the extract necessary for 50 % inhibition of A172 growth (IC50) was 710 μg/mL. The extract did not induce changes in proliferation and morphology of A172 glioblastoma cells. On the other side, production of ROS was increased in A172 cells treated with the extract. Observed cytotoxic effect of P. fruticosa extract might be based on increase in ROS generation upon treatment. Quantitative chemical analysis revealed the presence of twelve different polyphenols with the cis 3-O-caffeoylquinic acid being the most abundant. This study provided scientific evidence for further exploration of P. fruticosa as a promising natural anti-neurodegenerative therapeutic option.

AB  - Genetic markers for the prediction of biogeographical ancestry have proved to be effective tools for law enforcement agencies for many years now. In this study, we attempted to assess the potential of insertion-deletion markers (InDel) and microsatellites (STRs) as subsidiary polymorphisms for inference of Slavic population ancestry. For that purpose, we genotyped Slavic-speaking populations samples from Belarus, the Czech Republic, Poland, Serbia, Ukraine and Russia in 46 InDels and 15 STRs by PCR and capillary electrophoresis and analyzed for between-population differentiation with the use of distance-based methods (FST, principal component analysis and multidimensional scaling).
Additionally, we studied a sample from a Polish individual of well-documented genealogy whose biogeographic ancestry had previously been inferred by commercial genomic services using autosomal single nucleotide polymorphisms (SNPs), mitochondrial DNA and Y-SNP markers. For comparative purposes, we used genotype data collected in the “forInDel” browser and allele frequencies from previously published papers. The results obtained for InDels and STRs show that the Slavic populations constitute a genetically homogeneous group, with the exception of the Czechs differing clearly from the other tested populations. The analysis of the known Polish sample in the Snipper application proves the usefulness of the InDel markers on the continental level only. Conversely, microsatellites not only improve prediction, but are also informative if considered as an independent set of ancestry markers.

AB  - Identification of the signature molecular profiles involved in therapy resistance is of vital importance in developing new strategies for treatments and disease monitoring. Protein alpha-1 antitrypsin (AAT, encoded by SERPINA1 gene) is an acute-phase protein, and its high expression has been linked with unfavorable clinical outcome in different types of cancer; however, data on its involvement in therapy resistance are still insufficient. We analyzed SERPINA1 mRNA expression in three different multidrug-resistant (MDR) cell lines—U87-TxR, NCI-H460/R, and DLD1-TxR—and in U87 cells grown in alginate microfibers as a 3D cellular model of glioblastoma. Expression of IL-6 as a major modulator of SERPINA1 was also analyzed. Additionally, AAT protein expression in MDR cells was analyzed by immunofluorescence. SERPINA1 gene expression and AAT protein expression were significantly upregulated in all the tested MDR cell lines compared with their sensitive counterparts. Moreover, SERPINA1 was significantly upregulated in 3D models of glioblastoma, previously found to have upregulated drug-resistance-related gene expression compared with 2D cells. With the exception of NCI-H460/R, in all cell lines as well as in a 3D model of U87 cells, increase in SERPINA1 expression correlated with the increase in IL-6 expression. Our results indicate that AAT could be utilized as a biomarker of therapy resistance in cancer; however, further studies are needed to elucidate the mechanisms driving AAT upregulation in therapy resistance and its biological significance in this process.

AB  - BACKGROUND Although still considered a safer alternative to classical cigarettes, growing body of work points to harmful effects of electronic cigarettes (e-cigarettes) affecting a range of cellular processes. The biological effect of e-cigarettes needs to be investigated in more detail considering their widespread use. METHODS In this study, we treated V79 lung fibroblasts with sub-cytotoxic concentration of e-cigarette liquids, with and without nicotine. Mutagenicity was evaluated by HPRT assay, genotoxicity by comet assay and the effect on cellular communication by metabolic cooperation assay. Additionally, comprehensive proteome analysis was performed via high resolution, parallel accumulation serial fragmentation-PASEF mass spectrometry. RESULTS E-cigarette liquid concentration used in this study showed no mutagenic or genotoxic effect, however it negatively impacted metabolic cooperation between V79 cells. Both e-cigarette liquids induced significant depletion in total number of proteins and impairment of mitochondrial function in treated cells. The focal adhesion proteins were upregulated, which is in accordance with the results of metabolic cooperation assay. Increased presence of posttranslational modifications (PTMs), including carbonylation and direct oxidative modifications, was observed. Data are available via ProteomeXchange with identifier PXD032071. CONCLUSIONS Our study revealed impairment of metabolic cooperation as well as significant proteome and PTMs alterations in V79 cells treated with e-cigarette liquid warranting future studies on e-cigarettes health impact.

AB  - Drug resistance presents a major obstacle to the successful treatment of glioblastoma. Autophagy plays a key role in drug resistance, particularly in relation to targeted therapy, which has prompted the use of autophagy inhibitors to increase the effectiveness of targeted therapeutics. The ability of two Src tyrosine kinase inhibitors, Si306 and its prodrug pro-Si306, to induce autophagy was evaluated in the human glioblastoma cell line U87 and its multidrug-resistant counterpart U87-TxR. Autophagy markers were assessed by flow cytometry, microscopy, and Western blot, and induction of autophagy by these compounds was demonstrated after 3 h as well as 48 h. The effects of Si306 and pro-Si306 on cell proliferation and cell death were examined in the presence or absence of autophagy inhibition by bafilomycin A1. Combined treatments of Si306 and pro-Si306 with bafilomycin A1 were synergistic in nature, and the inhibition of autophagy sensitized glioblastoma cells to Src tyrosine kinase inhibitors. Si306 and pro-Si306 more strongly inhibited cell proliferation and triggered necrosis in combination with bafilomycin A1. Our findings suggest that modulation of Si306- and pro-Si306-induced autophagy can be used to enhance the anticancer effects of these Src tyrosine kinase inhibitors and overcome the drug-resistant phenotype in glioblastoma cells.

AB  - Tspan14 is a transmembrane protein of the tetraspanin (Tspan) protein family. Different members of the Tspan family can promote or suppress tumor progression. The exact role of Tspan14 in tumor cells is unknown. Earlier, mutational inactivation of the TSPAN14 gene has been proposed to coincide with a low survival rate in NSCLC patients. This study aimed to investigate the correlation of TSPAN14 lack of function with clinicopathological features of NSCLC patients, and to elucidate the role TSPAN14 might have in NSCLC progression. TSPAN14 expression was lower in tumor cells than non-tumor cells in NSCLC patients’ samples. The decreased gene expression was correlated with a low survival rate of patients and was more frequent in patients with aggressive, invasive tumor types. Additionally, the role of decreased TSPAN14 expression in the metastatic potential of cancer cells was confirmed in NSCLC cell lines. The highly invasive NSCLC cell line (NCI-H661) had the lowest TSPAN14 gene and protein expression, whereas the NSCLC cell line with the highest TSPAN14 expression (NCI-H460) had no significant metastatic potential. Finally, silencing of TSPAN14 in these non-metastatic cancer cells caused an increased expression of matrix-degrading enzymes MMP-2 and MMP-9, followed by an elevated capacity of cancer cells to degrade gelatin. The results of this study propose TSPAN14 expression as an indicator of NSCLC metastatic potential and progression.

AB  - Sdox is a hydrogen sulfide (H2S)-releasing doxorubicin effective in P-glycoprotein-overexpressing/doxorubicin-resistant tumor models and not cytotoxic, as the parental drug, in H9c2 cardiomyocytes. The aim of this study was the assessment of Sdox drug-like features and its absorption, distribution, metabolism, and excretion (ADME)/toxicity properties, by a multi- and transdisciplinary in silico, in vitro, and in vivo approach. Doxorubicin was used as the reference compound. The in silico profiling suggested that Sdox possesses higher lipophilicity and lower solubility compared to doxorubicin, and the off-targets prediction revealed relevant differences between Dox and Sdox towards several cancer targets, suggesting different toxicological profiles. In vitro data showed that Sdox is a substrate with lower affinity for P-glycoprotein, less hepatotoxic, and causes less oxidative damage than doxorubicin. Both anthracyclines inhibited CYP3A4, but not hERG currents. Unlike doxorubicin, the percentage of zebrafish live embryos at 72 hpf was not affected by Sdox treatment. In conclusion, these findings demonstrate that Sdox displays a more favorable drug-like ADME/toxicity profile than doxorubicin, different selectivity towards cancer targets, along with a greater preclinical efficacy in resistant tumors. Therefore, Sdox represents a prototype of innovative anthracyclines, worthy of further investigations in clinical settings.

AB  - Salvia nemorosa L. is a rich source of bioactive constituents. We have used different solvents to obtain 14 different extracts in order to evaluate solvents impact on S. nemorosa inflorescences bioactivities. Firstly, the extraction yield, chemical composition and cytotoxic properties towards HaCaT cell line were elaborated. Afterwards, we have studied the extracts bioactivity in terms of wound healing, antioxidant and antidiabetic potentials as well as antimicrobial and antibiofilm capacities; followed by the determination of the antimicrobial mechanism. The extracts yield ranged from 3.03% to 15.75% and they were dominated by epigallocatechin gallate and rosmarinic acid. The majority of extracts did not possess cytotoxic properties towards human keratinocytes. Butanol was the most appropriate solvent for the improvement of wound healing capacity. Combined extraction with ethanol and water resulted in the highest antioxidant potential of the extracts that could be attributed to the high abundance of detected polyphenols. Extraction with butanol led to the increased inhibition towards enzymes linked to type 2-diabetes and increase in antimicrobial capacities. The extracts have shown antibiofilm potential towards Staphylococcus lugdunensis biofilms with more than 90% inhibition for the most active ones. The selected extract EB7 reduced bacterial ability to adhere to human keratinocytes and provided immunomodulatory action in HaCaT cells exposed to S. lugdunensis. The antibacterial mechanism of action of the same extract was associated with moderate perturbation in the cell membrane integrity and with the reduction in bacterial mitochondrial activity. S. nemorosa inflorescences were abundant sources of bioactive polyphenols and with different extraction solvents their bioactivities were further improved. This study reported for the first time the effects of extraction solvents on various bioactivities of S. nemorosa inflorescences, supporting S. nemorosa role as a natural bioactive therapeutic agent with possible antioxidant, antidiabetic and antimicrobial applications.

AB  - Investigating membrane properties of plants is a challenging task, considering that success of
experiments is highly dependent on the possibility to isolate metabolically active protoplasts that
can withstand membrane current recordings. The aim of the present work is to obtain viable
protoplasts derived from root cells of Pisum sativum that can be used for the whole-cell patchclamp. We designed the procedure of the pea protoplasts isolation that delivers stable protoplasts
with preserved membrane integrity suitable for electrophysiological experiments. We applied a
custom approach for patch-clamping protoplasts using a microscope with a movable microscope
stage. We recorded prominent inward and prominent outward types of membrane current profiles of
protoplasts. Obtained data indicate that optimized isolation protocol and custom system for patchclamping, can be applied to study membrane properties of root protoplasts.

Инхибитори тирозин-киназа могу индуковати аутофагију која делује протективно на туморске ћелије. Способност инхибитора
Срц тирозин-киназе, деривата пиразоло[3,4-д]пиримидина Si306 и његовог пролека pro-Si306, да индукују аутофагију испитана је на ћелијској линији хуманог глиобластома U87 и њеној варијанти са вишеструком резистенцијом на лекове U87-TxR. Третман овим једињењима узроковао је појаву аутофагозома у ћелијама након 3 сата, а ефекат на индукцију аутофагије опстао је и након 48 сати што је утврђено анализом маркера аутофагије LC3 и p62. Инхибиција аутофагног флукса бафиломицином А1 значајно је увећала постојеће анти-пролиферативно дејство Si306 и pro-Si306. Такође, комбиновани третмани Срц инхибитора са бафиломицином А1 довели су до некрозе након 48 сати. Добијени резултати сугеришу да аутофагија индукована овим једињењима има заштитну улогу у ћелијама глиобластома и да се модулација аутофагије може користити за сензитизацију ћелија глиобластома на инхибиторе Срц тирозин-киназе. Поред тога, поменути ефекти Si306 и pro-Si306 нису умањени присуством вишеструкорезистентног фенотипа, што овим једињењима даје потенцијал за лечење резистентних тумора.

Herein, we studied chemical profile and biological activities of Phlomis fruticosa L. after plant material storage for 20 years. Chemical analyzes were performed by UHPLC-LTQ-Orbitrap/MS, and revealed presence of 44 compounds: including 13 phenolic acids, 9 phenylethanoids, 20 flavonoids and 2 phenolic related compounds (a phenolic acid derivative and an aliphatic alcohol). The extract showed antimicrobial activity, being the most potent against Aspergillus fumigatus with minimum inhibitory concentration of 0.31 mg/mL. Also, the extract was able to inhibit biofilm formed by Candida species and to inhibit biofilm formation by Staphylococcus aureus. Obtained results revealed that the extract has potential to interfere with the cell membrane permeability of Candida albicans and to suppress production of virulence factor staphyloxanthin in S. aureus. Furthermore, the extract inhibited the activity of α-amylase which is one of the therapeutic targets for diabetes type II. Also, the antiproliferative effect of the extract was demonstrated on human cancer cell lines, while the extract did not exhibit any cytotoxic effect on primary human cells. Based on the obtained results, P. fruticosa could be an interesting source of biologically active compounds even after long term storage.

AB  - Two newly synthesized 4-hydroxycoumarin bidentate ligands (L1 and L2) and their palladium(II) complexes (C1 and C2) were screened for their biological activities, in vitro and in vivo. Structures of new compounds were established based on elemental analysis, 1H NMR, 13C NMR, and IR spectroscopic techniques. The obtained compounds were tested for their antioxidative and cytotoxic activities and results pointed to selective antiradical activity of palladium(II) complexes towards •OH and -•OOH radicals and anti-ABTS (2,2 ′ -Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) cation radical) activity comparable to that of ascorbate. Results indicated the effect of C1 and C2 on the enzymatic activity of the antioxidative defense system. In vitro cytotoxicity assay performed on different carcinoma cell lines (HCT166, A375, and MIA PaCa-2), and one healthy fibroblast cell line (MRC-5) showed a cytotoxic effect of both C1 and C2, expressed as a decrease in carcinoma cells’ viability, mostly by induction of apoptosis. In vivo toxicity tests performed on zebrafish embryos indicated different effects of C1 and C2, ranging from adverse developmental effect to no toxicity, depending on tested concentration. According to docking studies, both complexes (C1 and C2) showed better inhibitory activity in comparison to other palladium(II) complexes.

According to docking studies, both complexes (C1 and C2) showed better inhibitory activity in comparison to other palladium(II) complexes.",

AB  - Phenolic compounds and biopotential (antioxidant, cellular antioxidant and cytotoxic activity) of grape pomace (GP) skin, seed, stem and whole GP originating from indigenous red grape variety Prokupac were evaluated. The UHPLC-Orbitrap MS4 analysis showed the presence of 75 phenolic compounds (57 non-anthocyanins and 18 anthocyanins), among which considerable content of ethyl gallate was observed and malvidin-3-O-hexoside-(8,8)-methylmethyne-(epi)catechin was identified. The stem had significant content of stilbenoids. The GP seed and the whole GP showed the highest antioxidant activity estimated by ABTS•+ DPPH• and H2O2 scavenging assays that were strongly correlated with the presence of flavan-3-ols, phenolic acids and ethyl gallate. The GP skin exerted cellular antioxidant activity on adenocarcinoma cells (EC50 = 56.4 mg TPCs/mL) which was strongly correlated with the presence of flavonols and anthocyanins. These by-products of Prokupac red grape variety are a notable source of phenolic compounds with good antioxidant activity that can be extensively used in food and pharmaceutical industry.

AB  - The aim of research was to determine polyphenols bioaccessibility and antioxidant properties of thermally-treated skimmed goat milk enriched with sunflower bee-collected pollen through in vitro digestion. HPLC analysis confirmed that pollen-enriched milk contained flavonols as the main phenolic fraction (80.7-76.2%) followed by phenolic acids (14.2-17.4%). Among individual compounds quercetin-3-O-glucoside (155.1-197.2 μg/L) and p-coumaric acid (29.5-30.7 μg/L) were the main quantified flavonols and phenolic acids, respectively. After digestion of milk/pollen sample, total polyphenols recovery was 30.71% with higher phenolic acids recovery (40.1%) compared to flavonols (28.3%) indicating strong interactions between caprine milk casein micelles and pollen polyphenols. Applied antioxidant assays (phosphomolybdenum, ABTS•+scavenging activity and ferrous-ion-chelating capacity) have confirmed complexity of prepared product- it had high ability to quench ABTS•+ radicals and to form chelating complexes with Fe2+ ions. Digestion provoked 20% reduction in total antioxidant capacity compared to the initial sample. TTSG milk/pollen powder could be good functional ingredient.

AB  - Anthriscus cerefolium (L.) Hoffm. is a plant traditionally used around the globe since antiquity. Although widely used in many traditional medicines in different cultures, from the scientific point of view it is poorly investigated. Glioblastoma, a tumor type with poor prognosis, is the most common and lethal brain tumor in adults. Current therapeutic strategies for glioblastoma include surgery, radiation and chemotherapy. On the other hand, it has been revealed that patients with cancers are highly susceptible to microbial infections due to the invasive nature of cancer treatment approaches. This study was designed to investigate the chemical profile of herba Anthriscii cerefoli methanolic extract by applying UHPLC-LTQ OrbiTrap MS4 analysis and to analyze its anti-glioblastoma and antimicrobial activities. This study revealed that methanolic extract of herba Anthrisc cerefolii contained phenolic acids and flavonoids, with 32 compounds being identified. Anti-glioblastoma activity was investigated in vitro using A172 glioblastoma cell line. The cytotoxic effects of the extract on A172 cells were compared to the same effect on primary human gingival fibroblast (HGF-1) cells. Decreased rate of proliferation and changes in cell morphology were detected upon treatment of A172 cells with the extract. The antimicrobial activity of extract was tested against Staphylococcus aureus and Candida species. The extract was active against the tested bacterium and yeasts, inhibiting free floating cells and microbial biofilms. This study is the first one to provide a detailed description of the chemical profile of A. cerefolium extract dealing with scientific insights into its anti-glioblastoma and antimicrobial activities.
