In addition, miRNA regulatory genes during stage-specific prostate cancer progression suggest the involvement of p53, EGFR-PI3K-Akt, IGF, interleukins, TGFB, VEGF, JAK/STAT, WNT signaling and their effectors as the most critical genes in prostate cancer via upregulation of growth factor receptors, specifically EGFR, or through PTEN inactivation. This evidence concerns the gene TGFB1 and Familial prostate cancer.
