Wilms' tumor 1 (WT1) encoding a transcription factor involved in the differentiation of granulosa cells (GCs) regulates androgen receptor in the development of male genitalia.
Conversely for two prostate growth control genes, androgen receptor (AR) and vascular endothelial growth factor (VEGF), known to be transcriptionally regulated by WT1, regulatory sequence conservation was observed and TF binding in vivo was confirmed by ChIP.
In contrast, intermediate filament vimentin expression was up-regulated in 6-48 h. Androgen receptor (AR) and Wilms' tumor gene 1 expression dramatically decreased after heat treatment.
We have recently demonstrated that the Wilms' tumor suppressor gene product, WT1, binds to multiple sites in the androgen receptor (AR) promoter and transcriptionally represses the AR gene promoter in vitro.
