- W2079058522 abstract "Prostate cancer (PCa) affects nearly 80% of men worldwide and is the second leading killer after lung cancer. The efficacy of current treatments offered in the clinics is highly compromised due to indolent nature of PCa, which provides large window of opportunity for prevention. Hence, the major focus of this study is to determine the chemo-preventive effects of Quercetin, a bioflavonoid, on prostate cancer. Effect of Quercetin on cell viability and IC50 was determined by MTT assay. The effect of Quercetin on cell motility was determined by wound healing assay. Potential role of Quercetin on cell cycle, apoptosis as well as genes involved in cell motility and invasion was determined using flow cytometry, Real-time qPCR and ELISA. Furthermore, Quercetin induced changes in signaling molecules involved in cell survival/apoptosis, cell cycle and cytoskeletal rearrangement was determined using antibody microarray. Prostate cancer cells treated with Quercetin showed dose and time dependent inhibition of proliferation/viability, and induction of apoptosis as compared to normal prostatic epithelial cells and untreated controls. Prostate cancer cell motility was inhibited in Quercetin treated cells. Prostate cancer cells were arrested in G2 phase of the cell cycle following Quercetin treatment. In addition to these, we found differential expression of caspases, matrix metalloproteinases (MMPs) and tissue inhibitor of MMPs in different PCa cell lines compared to untreated controls. Furthermore, antibody microarray analysis demonstrated selective modulation of genes and associated signaling cascades responsible for apoptosis induction, cellular motility, adhesion and invasion in Quercetin treated cells compared to controls. These findings suggest Quercetin as a potent chemo-preventive agent. In addition to this it can be also used with chemotherapeutic agents directed to G2 phase of the cell cycle, which may improve the efficacy of chemotherapeutics offered in clinics to treat advance prostate cancer.
