Abstract excerpt
1,25-Dihydroxyvitamin D (1,25D) inhibits growth of prostate cancer cells and has been proposed to play a protective role in prostate cancer. However, 25-hydroxyvitamin D 1alpha-hydroxylase (CYP27B1), the enzyme responsible for the cellular synthesis of 1,25D, is repressed in prostate cancer cells. Recently, we have identified a role for the transcription factor, Growth Factor Independent-1 (GFI1) in the...
