AB  - Introduction: Astrocytoma and glioblastoma are the most agressive type of brain tumor. Glioblastoma IDH wild-type is a primary tumor which develops de novo, while Astrocytoma IDH mutant progresses from lower grade tumors. They are characterized by high heterogeneity and resistance to therapy which develop as a consequence of accumulation of mutations that lead to genomic instability.
Methods: We analysed genomic instability in 66 patients with malign brain tumors using arbitrarily primed PCR as DNA profiling method. Comparing DNA profiles of tumor and normal (blood) tissues, we detected quantitative and qualitative differences. Quantitative differences are represented by different band intensities and correspond to chromosomal instability (CIN). Qualitative changes seen as band shifts represent microsatellite instability (MIN). We correlated frequencies of genomic instability with tumor gradus and histophatological data.
Results: In patients with Glioblastoma IDH wild-type, percentages of high total genomic instability, MIN and CIN were 65%, 32% and 57%, respectfully. In patients with Astrocytoma IDHmutant, percentages of high total genomic instability, MIN and CIN for gradus 3 were 45%, 36% and 72%, respectfully while they were 40%, 40% and 40%, for gradus 4. In patients with NOS (not otherwise specified glioblastoma) percentages are 50%, 50% and 70%, respectfully.
Conclusion: Our results show that Glioblastoma IDH wild-type and Astrocytoma IDH mutant gradus 3 have higher genomic instability, while it is lower in Astrocytoma IDH mutant gradus 4. These results are in line with evolutionary theory of origin of cancer. Genomic instability in NOS tumors could be used as a prognostic marker.

AB  - Рак дојке је најчешћи облик рака код жена са приближно 70% случајева који су
позитивни на хормонске рецепторе (HR+). Прекомерна експресија естрогенског

AB  - Breast cancer is the most prevalent form of cancer in women, with approximately
70% of cases being hormone receptor positive (HR+). While overexpression of estrogen
receptor (ER) is closely related with tumor proliferation, anti-estrogen therapies,
e.g., with tamoxifen, are common and effective approaches. Although treatment with
tamoxifen belongs to the group of targeted therapies, its effectiveness has also been
proven in hormone-independent types of breast cancer, which indicates the presence
of intracellular off-targets. Apart of the fact that tamoxifen showed significant
efficiency in the treatment of ER+ breast cancers, numerous patients developed resistance
towards it. With an aim to amplify its potential and overcome resistance, tamoxifen
has been modified with transition metals such as platinum (Pt) and palladium
(Pd). Pt-based compounds have traditionally been used in cancer chemotherapy,
while Pd complexes may lower the toxicity and be more effective against certain types
of cancer. The aim of this study was to evaluate the efficacy of tamoxifen modified
with Pt and Pd on a panel of breast cancer cell lines with different receptor expression
status. The tamoxifen derivative used as ligand diminished the viability of tumor cells
independently of ER expression, indicating that its antitumor action can be dominantly
ascribed to a ER-independent action. The experimental drugs induced caspase
independent apoptosis, with a more pronounced effect in the case of the Pd-based
derivatives. The efficacy of the Pd derivate can be further increased by abolishment
of the autophagic process. Taken together, derivatization of tamoxifen is a promising
strategy for hybrid molecule design.

AB  - Background: Estrogen receptor-positive (ER+) breast cancer accounts for approximately 70% of all cases and, concordantly, anti-estrogen therapies present a leading therapeutic choice. Interestingly, tamoxifen, which is the most commonly used drug, has also been proven effective in hormone-independent forms of breast cancer, suggesting the existence of intracellular off-targets. Frequent acquisition of therapy resistance presents a platform for the design of tamoxifen derivatives with a 2,2’-bipyridine unit enabling the coordination of transition metal moieties, such as copper(II) dichloride. Copper (Cu) is an essential element involved in the regulation of cellular growth and development. Disruption of its delicate homeostasis results in severe toxicity and hard medical conditions. Increased demand of cancer cells for this micronutrient makes it a valuable candidate for drug design in cancer treatment. The mechanism of action of Cu complexes is typically based on their ability to induce deadly oxidative stress. This study evaluated the efficacy of a copper–tamoxifen hybrid drug on a panel of breast cancer cell lines with varying receptor expression status. Material and Methods: The viability of breast adenocarcinoma cell lines MCF-7, MDA-MB-361, MDA-MB-231, 4T1 and glioma U251 was estimated by MTT and CV assays. Flow cytometric analysis of cells stained with annexin V-FITC/propidium iodide, ApoStat, acridine orange, dihydrorhodamine 123 (DHR),  dihydroethidium (DHE) or 4-amino-5-methylamino-2',7'-difluorofluorescein diacetate (DAF) was used to evaluate cell death, caspase activity, autophagy, production of reactive oxygen and nitrogen species (ROS/RNS), respectively. Results: The Cu-tamoxifen hybrid drug displayed substantially higher hormone-receptor (HR) independent cytotoxic activity compared to previously reported metal complexes with a similar tamoxifen vector.  Massive caspase-dependent apoptotic cell death is partially attenuated by an autophagic process that counteracts death signals. In contrast to the platinum analogue, the copper-based tamoxifen derivative reduces ROS/RNS that may be associated with the intracellular accumulation of the reduced form of CuI which is important for cuproptosis. Conclusion: This study demonstrates the potential of the copper–tamoxifen hybrid drug as an intriguing alternative to commonly used platinum complexes in treatment of cancer. Its safety and efficiency will be further estimated in vivo.

AB  - Lipoxygenases convert polyunsaturated fatty acids into biologically active metabolites such as inflammatory mediators-prostaglandins and leukotrienes. The inhibition of lipoxygenases is increasingly employed in the treatment of cancer. We evaluated the anticancer potential of two novel 5-lipoxygenase inhibitors, named CarbZDNaph and CarbZDChin, which are analogues of the commercially available inhibitor Rev-5901. The in vitro segment of this study was conducted on a mouse colorectal carcinoma cell line-CT26CL25. For an in vivo model, we induced tumors in BALB/c mice by the implantation of CT26CL25 cells, and we treated the animals with potential inhibitors. A 48 h treatment resulted in diminished cell viability. Calculated IC50 values (half-maximal inhibitory concentrations) were 25 μM, 15 μM and 30 μM for CarbZDNaph, CarbZDChin and Rev-5901, respectively. The detailed analysis of mechanism revealed an induction of caspase-dependent apoptosis and autophagy. In the presence of chloroquine, an autophagy inhibitor, we observed an increased mortality of cells, implying a cytoprotective role of autophagy. Our in vivo experiment reports tumor growth attenuation in animals treated with CarbZDChin. Compounds CarbZDNaph and Rev-5901 lacked an in vivo efficacy. The results presented in this study display a strong effect of compound CarbZDChin on malignant cell growth. Having in mind the important role of inflammation in cancer development, these results have a significant impact and are worthy of further evaluation.

AB  - Breast cancer (BC) is the most frequent type of malignancy and the leading cause
of cancer related death among women worldwide. More than 70% of all diagnosed invasive
BCs express steroid receptors and, as such, are subjected to endocrine therapy.
BC is exceptionally heterogeneous disease and therefore distinct treatment modalities
are necessary to address these differences. The aim of our study was to investigate
the impact of TP53 and PTEN tumor suppressor genes (TSGs) inactivation on BC
response to different treatment modalities, as well as, their possible cooperation, on
post-operative BC samples. To that end the patients were classified, based on applied
adjuvant therapy, into four distinct groups: those that received hormonal therapy
(HT) only, hormonal therapy combined with chemotherapy (HT/CHT), hormonal
therapy combined with chemo and biological therapy (HT/CHT/H), and other systemic
therapies that exclude HT (for example CHT or H). Functional inactivation of
TP53 and PTEN TSG’s were studied by mutation, loss of heterozygosity (LOH) and
hypermethylatyon analysis. Our results revealed that TP53 gene was altered in 63 out
of 90 specimens (70%), while the frequency of PTEN alterations was slightly lower,
54 out of 90 (60%) patients had inactivated PTEN. Simultaneous inactivation was
detected in 43 tested samples (48%) with significant association between two analyzed
TSGs. Further, we found that TP53 status has significant influence on patients’
therapy response. Patients with wild type TP53 show significantly better therapy response
regardless of the type of therapy, compared to carriers of altered p53 gene. In
support of this we showed that hormonally treated women with intact (wt) TP53 gene
had significantly longer survival rate (p=0.000001) when compared to: (i) hormonally
treated women with aberrant TP53gene, (ii) women with intact (wt) p53 subjected to
any of remaining three therapy combinations, and (iii) women with altered TP53 that
belong to second (HT/CHT), third (HT/CHT/H) or forth (systemic Th that exclude
HT) therapy group. Contrary to this, no significance was found between mutational status of PTEN and various treatment modalities. However, significant association
was found between the type of applied therapy and simultaneous alterations of these
two TSGs (p=0.00001).
AB  - Рак дојке је најчешћи тип малигнитета и водећи узрок смрти од канцера код
жена широм света. Више од 70% свих дијагностикованих инвазивних карцинома
дојке експримира стероидне рецепторе и као такви су подобни за ендокрину терапију. Канцер дојке је изузетно хетерогена болест и стога су неопходни различити модалитети лечења да би се превазишле ове разлике. Циљ нашег истраживања
био је да се испита утицај инактивације ТП53 и ПТЕН тумор супресорских гена
(ТСГ) у одговору на различите модалитете лечења на постоперативним узорцима
карцинома дојке. Са тим циљем пацијенткиње су класификоване, на основу примењене ађувантне терапије, у четири различите групе: оне које су примале само
хормонску терапију (ХТ), хормонску терапију у комбинацији са хемиотерапијом
(ХТ/ЦХТ), хормонску терапију у комбинацији са хемиотерапијом и биолошком
терапијом (ХТ). /ЦХТ/Х) и друге системске терапије које искључују ХТ (на пример ЦХТ или Х). Функционална инактивација ТП53 и ПТЕН тумор супресора
је студирана анализом мутационог статуса, губитка хетерозиготности (ЛОХ) и
анализом метилационог статуса. Наши резултати су показали да је ТП53 ген измењен код 63 од 90 узорака (70%), док је учесталост промена ПТЕН гена била
нешто нижа, 54 од 90 (60%) пацијената је имало инактивиран ПТЕН. Симултана
инактивација је детектована у 43 тестирана узорка (48%) са значајном повезаношћу инактивације два анализирана тумор супресор гена.
Даље, показали смо да статус ТП53 има значајан утицај на одговор пацијената
на терапију. Пацијенти са дивљим типом (wt) ТП53 показују значајно бољи терапијски одговор без обзира на врсту терапије, у поређењу са носиоцима измењеног TП53. У прилог овоме показали смо да су хормонски лечене жене са интактним (wt) ТП53 геном имале значајно већу стопу преживљавања (п=0,000001) у
поређењу са: (1) женама леченим хормонсом теерапијом са аберантним ТП53 геном, (2) женама са интактним (wt) TП53 подвргнутим било којој од преостале три терапијске комбинације, и (3) женама са измењеним ТП53 које припадају другој
(ХТ/ЦХТ), трећој (ХТ/ЦХТ/Х) или четвртој (системска терапија која искључује ХТ) терапијској групи. Супротно овоме, нисмо утврдили значајну асоцијацију
између мутационог статуса ПТЕН-а и различитих модалитета лечења. Међутим,
утврђена је значајна повезаност између врсте примењене терапије и истовремених промена ова два тумор супресор гена (п=0,00001).

AB  - Lung cancer is the most frequently diagnosed and lethal malignancy in the
world. Lung adenocarcinoma (LAC) and lung squamous cell carcinoma (LSCC)
are two subtypes of non-small cell lung cancer (NSCLC) which differ markedly in
key clinical and biological features. Despite this, they are usually treated similarly.
It is imperative to elucidate the mechanisms behind these differences in order to
implement better therapeutic modalities and biomarkers. Increased expression of
carbonic anhydrases Ca9 and Ca12 was observed in a broad array of tumors. Ca9
and Ca12 have a crucial role in the maintenance of the neutral intracellular pH and
the acidic extracellular microenvironment which stimulates the proliferation and
metastasis of tumor cells. Our aim was to detect possible difference in expression
level of Ca9 and Ca12 in LAC and LSCC, and to investigate whether the expression
of Ca9 and Ca12 was associated with the clinical course and outcome. We evaluated
the Ca9 and Ca12 expressions in 71 lung cancers, 35 (49%) LAC and 36 (51%)
LSCC. After RNA isolation and reverse transcription, relative RNA expression level
was evaluated using Real Time PCR and TaqMan technology. Ca9 and Ca12 expression
status was calculated according to the 2-ΔΔCT method. We used median value
of expression to designate low and high expression groups. High level of Ca9 and
Ca12 expression were detected in 49% (35/71) and 48% (34/71) of NSCLC samples,
respectively. Low levels of expression were identified in the rest of the specimens.
High expression of Ca12 was associated with LSCC subtype (p<0.0001). No associations
between Ca9 or Ca12 expression and clinicopathological parameters were
detected when assessed independently. However, patients with high expression of
both Ca9 and Ca12 lived significantly shorter compared to the Ca9/Ca12 low expression
group, (p=0.02). Our results suggest that Ca12 expression contributes to
the differences observed between LAC and LSCC tumors. The upregulation of Ca12 may promote the aggressive behavior of NSCLC. Ca9-high/Ca12-high expression
constitutes a ‘high risk’ profile in NSCLC.
AB  - Карцином плућа је најчешће дијагностикована и најсмртоноснија малигна болест у свету. Аденокрацином плућа (енг. lung adenocarcinoma, LAC) и карцином сквамозних ћелија плућа (енг. lung squamous cell carcinoma, LSCC) су два подтипа неситноћелијског карцинома плућа са израженим разликама у кључним клиничким и биолошким карактеристикама. Упркос томе, ови подтипови се најчешће лече на врло сличан начин. Изузетно је важно да се разјасне механизми у основи ових разлика како би се успоставили бољи биомаркери и приступи у лечењу. У бројним типовима тумора примећена је повећана експресија карбонске анхидразе (Са) 9 и 12. Са9 и Са12 имају круцијалну улогу у одржавању неутралне унутарћелијске вредности рН и киселе ванћелијске микросредине што стимулише пролиферцију и метастазирање ћелија тумора. Наши циљеви су били да детектујемо могуће разлике у нивоу експресије Са9 и Са12 у LAC и LSCC, и да истражимо да ли је експресија Са9 и Са12 асоцирана са клиничким током и исходом болести. Испитали смо експресију Са9 и Са12 у 71 узорку карцинома плућа, 35 (49%) LAC и 36 (51%) LSCC. Након изолације РНК и реверзне транскрипције, релативни ниво експресије РНК утврђен је коришћењем квантитативног РСR-а у реалном времену базираног на TaqMan технологији. За израчунавање статуса експресије Са9 и Са12 коришћена је 2-ΔΔCT метода. Употребили смо медијану вредности експресије да дефинишемо групе са високом, односно ниском експресијом. Висок ниво експресије Са9 детектован је у 49% (35/71), а Са12 у 48% (34/71) узорака. Низак ниво експресије је идентификован у преосталим узорцима. Висока експресија Са12 била је асоцирана са LSCC подтипом (р<0.0001). Када су експресија Са9 и Са12 посматране независно, није уочена њихова асоцијација са клиничко-хистопатолошким параметрима. Међутим, пацијенти који су истовремено имали високу експресију и Са9 и Са12 су живели значајно краће у односу на пацијенте са ниском експресијом Са9/Са12, (р=0.02). Наши резултати сугеришу да експресија Са12 доприноси разликама уоченим између LAC и LSCC тумора. Појачана експресија Са12 можда подстиче агресивно понашање неситноћелијског карцинома плућа. Са9 висока/Са12 висока експресија представља профил “високог ризика” у неситноћелијском карциному плућа.

AB  - Introduction. Breast cancer (BC) is the most frequent type of malignancy and the leading cause of cancer related death among women worldwide. BC is exceptionally heterogeneous disease and therefore distinct treatment modalities are necessary to address these differences. The aim of our study was to investigate the impact of TP53 and PTEN tumor suppressor genes (TSGs) inactivation on BC response to different treatment modalities and their possible cooperation, on post-operative BC samples.
Methods. Patients were classified, based on applied adjuvant therapy, into four distinct groups: those that received hormonal therapy (HT) only, hormonal therapy combined with chemotherapy (HT/CHT), hormonal therapy combined with chemo and biological therapy (HT/CHT/H), and other systemic therapies that exclude HT. Functional inactivation of TP53 and PTEN TSG’s were studied by mutation, loss of heterozygosity (LOH) and hypermethylation analysis.
Results. Our results revealed that TP53 gene was altered in 63 out of 90 specimens (70%), while the frequency of PTEN alterations was slightly lower, 54 out of 90 (60%). Simultaneous inactivation was detected in 43 tested samples (48%) with significant association between two analyzed TSGs. Further, we found that TP53 status has significant influence on patients’ therapy response. Contrary to this, no significance was found between mutational status of PTEN and various treatment modalities. However, significant association was found between the type of applied therapy and simultaneous alterations of these two TSGs (p = 0.00001). 
Conclusion. Patients with wtTP53 show significantly better therapy response regardless of the type of therapy, compared to carriers of altered TPp53 gene.

je izuzetno heterogena bolest i stoga su neophodni različiti modaliteti lečenja da bi se pokrile ove
razlike. Cilj našeg istraživanja je bio da se ispita uticaj inaktivacije TP53 i PTEN tumor supresorskih
gena (TSG) na odgovor RD na različite modalitete lečenja, kao i njihova moguća saradnja u tome, na
postoperativnim uzorcima RD.
Metode. Pacijentkinje su klasifikovane, na osnovu primenjene adjuvantne terapije, u četiri različite
grupe: one koje su primale samo hormonsku terapiju (HT), hormonsku terapiju u kombinaciji sa hemoterapijom (HT/CHT), hormonsku terapiju u kombinaciji sa hemoterapijom i biološkom terapijom
(HT/CHT/H) i druge sistemske terapije koje isključuju HT. Funkcionalna inaktivacija TP53 i PTEN TSG
je proučavana analizom mutacionog statusa, gubitka heterozigotnosti (LOH) i metilacionog statusa.
Rezultati. Naši rezultati su pokazali da je TP53 gen izmenjen kod 63 od 90 pacijenata (70%), dok je
učestalost promena PTEN gena bila nešto niža, 54 od 90 (60%). Simultana inaktivacija je detektovana
u 43 testirana uzorka (48%) sa značajnom povezanošću između dva analizirana TSG-a. Dalje, pokazali
smo da status TP53 ima značajan uticaj na odgovor pacijenata na terapiju. Suprotno ovome, nismo
pokazali značajnu asocijaciju između mutacionog statusa PTEN-a i različitih modaliteta lečenja. Međutim, utvrđena je značajna povezanost između primenjenih terapija i simultanih inaktivacija ova
dva TSG-a (p = 0,00001).
Zaključak. Pacijenti sa wtTP53 pokazuju značajno bolji terapijski odgovor bez obzira na vrstu terapije u poređenju sa nosiocima mutiranog TP53 gena.

AB  - Background: Breast cancer (BC) is the most frequent type of malignancy and the leading cause of cancer related death among women worldwide. Multiple interconnected factors determine BC response to therapy and clinical outcome. TP53 and PTEN are the most frequently altered tumor suppressor genes (TSGs) in human cancers. Material and methods: To determine the potential influence of TSGs on the response to therapy we analyzed alterations of TP53 and PTEN in 90 BC specimens. The specimens were stratified based on systemic adjuvant therapy (hormonal therapy only (HT), HT and chemotherapy (HT/CHT), HT/CHT and biological therapy (HT/CHT/H). Functional inactivation of TP53 by mutations and/or loss of heterozygosity (LOH) and PTEN by LOH and/or promoter hypermethylation, were tested using single-strand conformational polymorphism (SSCP) analysis, gene sequencing, fragment analysis and methylation-specific PCR (MS-PCR) methods respectively. Results: Altered TP53 was found in 63/90 specimens (70%) while 54/90 (60%) had inactivated PTEN. Inactivation of PTEN was more frequent in tumors with altered TP53. Patients with altered TP53, lived shorter (p=0.0007) compared to those with wild type (wt) gene. The survival of patients with both TSGs altered was shorter compared to wt genes (p=0.024). Patients with wtTP53 treated with HT had longer survival (p=0.000001) when compared to all other groups. Women with both TSGs altered who received tamoxifen lived shorter than those on HT with both/one TSGs intact (p = 0.03). Conclusion: Patients with wtTP53 showed significantly better therapy response regardless of type of therapy, compared to carriers of altered TP53.

AB  - Owing to the involvement of cyclooxygenase-2 (COX-2) in carcinogenesis, COX-2-selective inhibitors are increasingly studied for their potential cytotoxic properties. Moreover, the incorporation of carboranes in structures of established anti-inflammatory drugs can improve the potency and metabolic stability of the inhibitors. Herein, we report the synthesis of carborane-containing derivatives of rofecoxib that display remarkable cytotoxic or cytostatic activity in the micromolar range with excellent selectivity for melanoma and colon cancer cell lines over normal cells. Furthermore, it was shown that the carborane-modified derivatives of rofecoxib showed different modes of action that were dependent on the cell type.

AB  - Ketoprofen is a widely used nonsteroidal anti-inflammatory drug (NSAID) that also exhibits cytotoxic activity against various cancers. This makes ketoprofen an attractive structural lead for the development of new NSAIDs and cytotoxic agents. Recently, the incorporation of carboranes as phenyl mimetics in structures of established drugs has emerged as an attractive strategy in drug design. Herein, we report the synthesis and evaluation of four novel carborane-containing derivatives of ketoprofen, two of which are prodrug esters with an nitric oxide-releasing moiety. One of these prodrug esters exhibited high cytostatic activity against melanoma and colon cancer cell lines. The most pronounced activity was found in cell lines that are sensitive to oxidative stress, which was apparently induced by the ketoprofen analogue.

AB  - 5-Lipoxygenase converts arachidonic acid into leukotrienes, which are involved in inflammation and angiogenesis. The introduction of carboranes can improve the pharmacokinetic behavior of metabolically less stable pharmaceutics. Herein we report the syntheses of several carborane-based inhibitors of the 5-lipoxygenase pathway. The isosteric replacement of phenyl rings by carboranes leads to improved cytotoxicity toward several melanoma and colon cancer cell lines. For the colon cancer cell line HCT116, the co-inhibition of heat shock protein 90 was observed.

AB  - The progression of cancer is accelerated by increased proliferation, angiogenesis, and inflammation. These processes are mediated by leukotrienes. Several cancer cell lines overexpress 5-lipoxygenase, an enzyme that converts arachidonic acid into leukotrienes. An early inhibitor of the 5-lipoxygenase pathway is Rev-5901, which, however, lacks in invivo efficacy, as it is rapidly metabolized. We investigated the introduction of carboranes as highly hydrophobic and metabolically stable pharmacophores into lipoxygenase inhibitors. Carboranes are icosahedral boron clusters that are remarkably stable and used to increase the metabolic stability of unstable pharmaceutics without changing their biological activity. By introduction of meta-carborane into Rev-5901, the first carborane-based inhibitor of the 5-lipoxygenase pathway was obtained. We report the synthesis and inhibitory and cytotoxic behavior of these compounds toward several melanoma and colon cancer cell lines and their related anticancer mechanisms.
