1,25-Dihydroxyvitamin D₃ Suppresses Prognostic Survival Biomarkers Associated with Cell Cycle and Actin Organization in a Non-Malignant African American Prostate Cell Line.

ABSTRACT: Vitamin D₃ is a steroid hormone that confers anti-tumorigenic properties in prostate cells. Serum vitamin D₃ deficiency has been associated with advanced prostate cancer (PCa), particularly affecting African American (AA) men. Therefore, elucidating the pleiotropic effects of vitamin D on signaling pathways, essential to maintaining non-malignancy, may provide additional drug targets to mitigate disparate outcomes for men with PCa, especially AA men. We conducted RNA sequencing on an AA non-malignant prostate cell line, RC-77N/E, comparing untreated cells to those treated with 10 nM of vitamin D₃ metabolite, 1α,25(OH)₂D₃, at 24 h. Differential gene expression analysis revealed 1601 significant genes affected by 1α,25(OH)₂D
