AB  - Glioblastoma (GBM), as the most aggressive brain tumor, displays a high expression of Src tyrosine kinase, which is involved in the survival, migration, and invasiveness of tumor cells. Thus, Src emerged as a potential target for GBM therapy. The effects of Src inhibitors pyrazolo[3,4-d]pyrimidines, Si306 and its prodrug pro-Si306 were investigated in human GBM cell lines (U87 and U87-TxR) and three primary GBM cell cultures. Primary GBM cells were more resistant to Si306 and pro-Si306 according to the 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. However, the ability of all GBM cells to degrade the extracellular matrix was considerably compromised after Si306 and pro-Si306 applications. Besides reducing the phosphorylation of Src and its downstream signaling pathway components, both compounds decreased the phosphorylated form of focal adhesion kinase (FAK) and epidermal growth factor receptor (EGFR) expression, showing the potential to suppress the aggressiveness of GBM. In vivo, Si306 and pro-Si306 displayed an anti-invasive effect against U87 xenografts in the zebrafish embryo model. Considering that Si306 and pro-Si306 are able to cross the blood-brain barrier and suppress the spread of GBM cells, we anticipate their clinical testing in the near future. Moreover, the prodrug showed similar efficacy to the drug, implying the rationality of its use in clinical settings.

AB  - Methanol extracts of three endemic Nepeta species were analyzed for their main secondary metabolites, terpenes and phenolics, and further investigated for antioxidant capacity and embryonic toxicity in zebrafish. UHPLC/DAD/(±) HESI-MS/MS analysis showed that the dominant compound in N. rtanjensis was trans,cis-nepetalactone, the cis,trans isomer of this monoterpene lactone was dominant in N. sibirica, while nepetalactone was detected only in traces in N. nervosa. In all investigated species, rosmarinic acid was the dominant phenolic compound, while other identified phenolic acids (chlorogenic, neochlorogenic and caffeic) were present in considerably lower amounts. ABTS and DPPH assays showed that the methanol extracts of N. rtanjensis, N. sibirica and especially N. nervosa possessed strong antioxidant activities, with the FRAP assay revealing high ferric-reducing abilities for all three tested species. Such a strong antioxidant potential, especially as manifested in the DPPH and FRAP assays, can be attributed to phenolic acids, and in the first place to rosmarinic acid. Increased lethality of zebrafish embryos in any of the treatments was not observed, but several toxic effects on embryonic development were recorded, such as pericardial and yolk sac edema. As in other Nepeta species, the three studied endemic species possessed a great potential for food conservation or as medicinal supplements if applied in optimized concentrations; however, alternative sources of plant material (e.g. field cultivation) should be established bearing in mind their vulnerability in nature.

AB  - Cancer drug resistance and poor selectivity towards cancer cells demand the constant search for new therapeutics. PI3K-Akt-mTOR and RAS-MAPK-ERK signaling pathways are key mechanisms involved in cell survival, proliferation, differentiation, and metabolism and their deregulation in cancer can promote development of therapy resistance. We investigated the effects of targeted inhibitors (wortmannin, GSK690693, AZD2014 and tipifarnib) towards these two pathways on early zebrafish and sea urchin development to assess their toxicity in normal, fast proliferating cells. PI3K inhibitor wortmannin and RAS inhibitor tipifarnib displayed highest toxicity while GSK690693, a pan-Akt kinase inhibitor, exhibited a less significant impact on embryo survival and development. Moreover, inhibition of the upstream part of the PI3K-Akt-mTOR pathway (wortmannin/GSK690693 co-treatment) produced a synergistic effect and impacted zebrafish embryo survival and development at much lower concentrations. Dual mTORC1/mTORC2 inhibitor AZD2014 showed no considerable effects on embryonic cells of zebrafish in concentrations substantially toxic in cancer cells. AZD2014 also caused the least prominent effects on sea urchin embryo development compared to other inhibitors. Significant toxicity of AZD2014 in human cancer cells, its capacity to sensitize resistant cancers, lower antiproliferative activity against human normal cell lines and fast proliferating embryonic cells could make this agent a promising candidate for anticancer therapy.

AB  - Cucumber (Cucumis sativus) fruit has been used in cuisine worldwide, while its leaves are rich in immunomodulatory compounds. Cucumber leaf extract (CLE) was characterized by the predominance of triterpenoids cucurbitacins and significant levels of phenolics. Effects of CLE on CD4 + T helper (Th) cells and macrophages, as the major encephalitogenic cells in the autoimmunity of the central nervous system were investigated in our study. CLE potently inhibited production of major pathogenic Th cytokines: interferon-gamma and interleukin-17, as well as of nitric oxide and reactive oxygen species in macrophages. Antigen-presenting activity of macrophages and dendritic cells was also affected by CLE. The effects of CLE were co-incident with modulation of NFκB and p38 MAPK signaling. Concentrations of CLE used in vitro did not show toxic effects on zebrafish embryos. Moreover, CLE inhibited generation of encephalitogenic cells in vivo. These results demonstrate that CLE deserve further investigation on its anti-encephalitogenic therapeutic properties.

AB  - Autophagy is linked to multiple cancer-related signaling pathways, and represents a defense mechanism for cancer cells under therapeutic stress. The crosstalk between apoptosis and autophagy is essential for both tumorigenesis and embryonic development. We studied the influence of autophagy on cell survival in pro-apoptotic conditions induced by anticancer drugs in three model systems: human cancer cells (NCI-H460, COR-L23 and U87), human normal cells (HaCaT and MRC-5) and zebrafish embryos (Danio rerio). Autophagy induction with AZD2014 and tamoxifen antagonized the pro-apoptotic effect of chemotherapeutics doxorubicin and cisplatin in cell lines, while autophagy inhibition by wortmannin and chloroquine synergized the action of both anticancer agents. This effect was further verified by assessing cleaved caspase-3 and PARP-1 levels. Autophagy inhibitors significantly increased both apoptotic markers when applied in combination with doxorubicin while autophagy inducers had the opposite effect. In a similar manner, autophagy induction in zebrafish embryos prevented cisplatin-induced apoptosis in the tail region while autophagy inhibition increased cell death in the tail and retina of cisplatin-treated animals. Autophagy modulation with direct inhibitors of the PI3kinase/Akt/mTOR pathway (AZD2014 and wortmannin) triggered the cellular response to anticancer drugs more effectively in NCI-H460 and zebrafish embryonic models compared to HaCaT suggesting that these modulators are selective towards rapidly proliferating cells. Therefore, evaluating the autophagic properties of chemotherapeutics could help determine more accurately the fate of different cell types under treatment. Our study underlines the importance of testing autophagic activity of potential anticancer agents in a comparative approach to develop more rational anticancer therapeutic strategies.

AB  - Increased circulating alpha-1-antitrypsin (AAT) correlates with cancer stage/aggressiveness, but its role in cancer biology is unclear. We revealed antagonistic effect of AAT to cisplatin-induced cytotoxicity in prostate (PC3) and melanoma (A375) cancer cell lines. Moreover, AAT abrogated cytotoxicity of MEK inhibitor U0126 in PC3 cell line. Weaker antagonistic effect of AAT on cytotoxicity of PI3/Akt and NF-kB inhibitors was also observed. In addition, cisplatin increased AAT gene expression in transfected PC3 cells. However, AAT derived from transfected PC3 cells did not antagonize cisplatin-induced cytotoxicity. In conclusion, these results suggest possible association between high circulating AAT and cisplatin resistance.

AB  - Cucurbitacin E (CucE) is a highly oxidized steroid consisting of a tetracyclic triterpene. It is a member of a Cucurbitacin family of biomolecules that are predominantly found in Cucurbitaceae plants. CucE has already been identified as a potent anti-inflammatory compound. Here, its effects on CD4(+) T helper (Th) cells and macrophages, as the major encephalitogenic cells in the autoimmunity of the central nervous system, were investigated. Production of major pathogenic Th cell cytokines: interferon-gamma and interleukin-17 were inhibited under the influence of CucE. The effects of CucE on CD4(+) T cells were mediated through the modulation of aryl hydrocarbon receptor, STAT3, NFκB, p38 MAPK, and miR-146 signaling. Further, production of nitric oxide and reactive oxygen species, as well as phagocytic ability, were inhibited in macrophages treated with CucE. These results imply that CucE possesses powerful antiencephalitogenic activity.

AB  - Alpha-1-antitrypsin (AAT), an acute phase protein, is the principal circulatory anti-protease. This multifunctional protein is encoded by the SERPINA1 gene. Although AAT was recognised as a potential tumour marker, its role in cancer biology remains unknown. Given that it has been demonstrated that AAT has an anti-apoptotic property against non-malignant cells, we aimed to investigate whether AAT affects apoptosis in a colon cancer cell line (HCT116). The presence of AAT in the HCT116 cell culture antagonized cytotoxicity of blockers of MEK1/2, PI3K/Akt pathways as well as NF-κB. The dominantly recovered cell viability was observed in the co-treatment with MEK1/2 inhibitor U0126. In addition, it was revealed that AAT almost completely abolished U0126-induced apoptosis through maintenance of the autophagy process. Our study revealed for the first time that the observed cyto-protection triggered by AAT was accompanied by sustained autophagy which opposed apoptosis. These results may contribute to understanding of the role of AAT in cancer development and evaluation of efficacy of cancer therapy.

AB  - Background: The mutant CCR5Δ32 allele confers resistance to HIV infection. Several hypotheses regarding its origin and persistence in the human population have been proposed. It is assumed that the Δ32 mutation was introduced in Northern or Eastern Europe and that it spread to the south. Although the frequency of CCR5Δ32 was determined in numerous European nations and regions, further data are needed to complete the puzzle of CCR5Δ32 distribution within the continent. Methods: To this end, CCR5Δ32 frequency was determined in a Serbian population (sample size 352). DNA was extracted from peripheral whole blood and polymerase chain reaction specific for CCR5 gene was performed. A reaction product of 263 bp was obtained from the wild­type CCR5 sequence and a product of 231 bp was obtained from the truncated CCR5Δ32 sequence. Results: Overall allele frequency of CCR5Δ32 is 4.55%; 0.57% of individuals in the examined population are homozygous and 8.52% are heterozygous for CCR5Δ32. Conclusions: The determined frequency of the CCR5Δ32 allele in a Serbian population is unexpectedly low, considering ethnically related populations.
AB  - Uvod: Nosioci alela CCR5Δ32 su relativno rezistentni na infekciju HIV-om. Postoji nekoliko hipoteza o poreklu i održanju ovog alela u ljudskoj populaciji. Pretpostavlja se da je mutacija Δ32 nastala u populaciji severne ili istočne Evrope i da se potom proširila ka jugu. Iako je učestalost CCR5Δ32 određena u mnogim evropskim populacijama, dodatni podaci su neophodni za formiranje sveobuhvatne slike o distribuciji CCR5Δ32 u Evropi. Zbog toga smo u našoj studiji odredili učestalost CCR5Δ32 u srpskoj populaciji, za koju do ovog rada nisu postojali takvi podaci. Metode: DNK je izolovana iz periferne krvi 352 osobe. U reakciji lančanog umnožavanja korišćeni su prajmeri specifični za gen CCR5. Dobijen je proizvod od 263 bp na osnovu matrice 'wild type', sekvence CCR5 gena, a proizvod od 231 bp na osnovu okrnjene sekvence gena CCR5 (CCR5Δ32). Ukupna učestalost alela CCR5Δ32 u srpskoj populaciji iznosi 4,55%. Rezultati: Od ukupnog broja analiziranih osoba, identifikovano je 8,52% heterozigotnih i 0,57% homozigotnih nosilaca za ovaj alel.
