Cooperative behavior of the nuclear receptor superfamily and its deregulation in prostate cancer.

ABSTRACT: The current study aimed to assess the topology of the nuclear receptor (NR) superfamily in normal prostate epithelial cells and its distortion in prostate cancer. Both in vitro and in silico approaches were utilized to profile NRs expressed in non-malignant RWPE-1 cells, which were subsequently investigated by treating cells with 132 binary NR ligand combinations. Nine significant cooperative interactions emerged including both superadditive [22(R)-hydroxycholesterol and eicosatetraenoic acid] and subadditive [1α,25(OH)2D3 and chenodeoxycholic acid] cellular responses, which could be explained in part by cooperative control of cell-cycle progression and candidate gene expression. In addition, publicly available data were employed to assess NR expression in human prostate tissue. Common and
