In subnetwork of the 4 miRNAs, peroxisome proliferative activated receptor, alpha (PPARA) and cyclic AMP-responsive element modulator (CREM) were the critical regulated TFs.Four up-regulated miRNAs (hsa-miR-1207-5p, hsa-miR-1184, hsa-miR-182, and hsa-miR-183) and 2 TFs (PPARA and CREM) were identified as key regulators in PC progression.
We identified ARA70, a coactivator of the androgen receptor and PPARgamma, as a ligand-enhanced coactivator of PPARalpha in the prostate cancer cell line DU145.
Using the mRNA differential display technique and Northern blot analysis, we have shown that chronic exposure of the prostate cancer epithelial cell line LNCaP to the synthetic androgen mibolerone results in the down-regulation of PPARalpha mRNA.
