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. The gene discussed is PTEN; the disease is Familial prostate cancer.
