Crosstalk Between Vitamin D₃- And Testosterone-Mediated Signaling In Prostate Cancer Cells, Wei-Lin Winnie Wang

Legacy Theses & Dissertations (2009 - 2024)

Contrary to the common belief that prostate cancer is a hormone dependent disease, the incidence of prostate cancer and associated mortality actually increases significantly after serum androgen levels decline. This led us to hypothesize that androgen depletion in elder men is an underlying cause for the development and progression of prostate cancer. In addition, serum vitamin D₃ levels also decline in older men. Epidemiological and experimental data support an anti-neoplastic activity of vitamin D₃ in colorectal and breast cancers through regulation of cell proliferation, apoptosis, cell differentiation and metastasis. The effects of vitamin D₃ on prostate cancer …
