SMARCD1 and posterior cortical atrophy: On the other hand, overexpression of miR-99b-5p (i.e. via transfection of miR-99b-5p mimic) targets/inhibits AR, mTOR and SMARCD1 simultaneously and blocks the translocation of mTOR/AR/SMARCD1 complex from cytoplasm to nucleus, consequently suppressing cell proliferation/survival and enhancing the cell apoptosis in PCa (especially AA PCA and CRPC).
