IFIT5 and posterior cortical atrophy: Thus, we examined both miR‐101 and miR‐128 levels in IFIT5‐elicited prostaspheres and found significant downregulation of both mature miRs in prostaspheres derived from different PCa lines (Figure 4A), which appear to be dose‐dependent suppression by IFIT5 overexpression (OE) (Figure S4A).
