MC1R Arg(160)/Arg(160) homozygotes were at increased risk (P = 0.027, odds ratio = 1.94) while TYR A2/A2 homozygotes were at reduced risk of prostate cancer (P = 0.033, odds ratio = 0.48).
Polymorphic variants in genes associated with pigmentation including melanocyte stimulating hormone receptor and tyrosinase are also associated with prostate cancer risk.
Cytotoxic activities against MCF-7 (breast cancer), PC-3 (prostate cancer), and 3T3 (nontumor) of the extracts and cytotoxic, antioxidant, cholinesterase, and tyrosinase inhibitory activities of all isolated compounds were evaluated.
