The Monoamine Oxidase A gene promoter repeat and prostate cancer risk

Background Amine catabolism by Monoamine Oxidase A (MAOA) contributes to oxidative stress, which plays a role in prostate cancer (PCa) development and progression. An upstream variable-number tandem repeat (uVNTR) in the MAOA promoter influences gene expression and activity, and may thereby affect PCa susceptibility.
