Men of African Ancestry are primed for aggressive prostate cancer by high prostate androgens driven by vitamin D deficiency and megalin - SUMMARY Studies have demonstrated an increased risk of aggressive prostate cancer (PCa) with vitamin D deficiency. Mounting evidence from my lab demonstrates that vitamin D deficiency alters the hormone levels of the prostate, which may contribute to the increased risk of aggressive PCa in vitamin D-deficient men. Our recent publications and preliminary data show that vitamin D status regulates dihydrotestosterone levels in the prostate, providing a mechanism by which vitamin D affects PCa aggressiveness. We further implicate megalin as mediating the effect of vitamin D on prostate androgens. Our long-term goal is to thoroughly examine the relationship between vitamin D and androgen hormones systemically. Here, we propose to examine megalin as a critical protein involved in prostate hormone regulation. The project includes three complementary, yet independent aims and the approach combines analysis of patient-derived models and mouse studies with clinical samples. This proposal aims to test the hypothesis that vitamin D deficiency leads to increased prostatic androgens via megalin, resulting in an increased risk of aggressive PCa. In contrast to serum levels, there is a paucity of information regarding the regulation of intra-tissue levels of hormones. Given that megalin regulates prostate T levels AND that megalin is regulated by vitamin D, further understanding this mechanism will provide crucial new insight into the consequences of vitamin D deficiency. New insight that directly links vitamin D status to prostate androgens has the potential to move the needle for general practitioners who would then take vitamin D deficiency seriously. Our findings may lead to increased screening for and treatment of vitamin D deficiency, ultimately decreasing the burden of aggressive and lethal PCa.
