miR-27a/b prevent pUbS65 accumulation upon mitochondrial damage. a, b Overexpression of PINK1 increased pUbS65 accumulation in HeLa cells only when incubated with CCCP. 48 h post-transfection, cells were incubated with 10 μM CCCP for 2 h and pUbS65 levels were determined by Western blot (n = 3, two-way ANOVA). c, d Overexpression of miR-27a/b inhibited pUbS65 accumulation by CCCP in HeLa cells (n = 4, two-way ANOVA). e, f Inhibition of endogenous miR-27a/b increased pUbS65 accumulation by CCCP in HeLa cells (n = 4, two-way ANOVA). PINK1 levels were normalized to corresponding GAPDH level and quantified as a percentage of control. Values are mean ± SEM (n.s. = non-significant, **p < 0.01, ***p < 0.001)
