AR and posterior cortical atrophy: These miRNAs are also known to be associated with specific aspects of PCa oncogenesis, including androgen receptor (AR) signaling [39,40], cell cycle regulation [40], cell proliferation and differentiation [26,41], epithelial–mesenchymal transition (EMT) [21,42,43,44], cell growth, apoptosis [45,46,47], adhesion and invasion [22], extraprostatic extension of the tumors [32], metastasis [38,42], biochemical failure [36,41], and hormone refractory [30,33].
