Proliferation And Migration

Prostate cancer (PCa) has a high incidence worldwide. One of the major causes of PCa resistance is intratumoral hypoxia. In solid tumors, hypoxia is strongly associated with malignant progression and resistance to therapy, which is an indicator of poor prognosis. The antiproliferative effect and induced death caused by doxorubicin, epirubicin, cisplatin, and flutamide in a hormone-independent PCa cell line will be evaluated. The hypoxia effect on drug resistance to these drugs, as well as cell proliferation and migration, will be also analyzed. All drugs induced an antiproliferative effect and also cell death in the cell line under study. Hypoxia made the cells more resistant to all drugs. Moreover, our results reveal that long time cell exposure to hypoxia decreases cellular proliferation and migration. Hypoxia can influence cellular resistance, proliferation, and migration. This study shows that hypoxia may be a key factor in the regulation of PCa.

Natural Sources

AbstractObjectivesRecently, phenolic compounds (quercetin, kaempferol, ellagic acid (EA), and myricetin) as natural sources have been suggested to be used for treatment and chemoprevention of prostate cancer. Since rosehip includes the above molecules in high concentration, we set out to investigate possible anti-proliferative effect of rosehip tea on the prostate cancer cell line.MethodsThe flavonol content of rosehip tea prepared at different temperatures and time intervals was determined first and then the antiproliferative effect of tea samples was established by adding tea samples to the prostate cancer cell line (VCaP and LNCaP).ResultsQuercetin was more effective in LNCaP cell than in VCaP cell (IC50 = 20 and 200 μM, respectively). The boiled fruit shredded at minute 7 showed the highest levels of quercetin, EA and kaempferol and the boiled fruit at minute 7 had the highest levels of kaempferol and EA. The tea samples were prepared in concentrations relevant to their IC50 values, added to the VCaP and LNCaP cell lines. The antiproliferative effect of rosehip tea on VCaP cells was slightly greater than that of LNCaP cells.ConclusionEach of the flavonols exhibits an antiproliferative effect. Our data clearly indicated that rosehip as a natural source of all flavonols had an antiproliferative effect on androgen-sensitive prostate cancer. Now that it is important to use natural sources in cancer, rosehip seems to be a promising natural product to be used to treat the prostate illness.
