Inhibition of endogenous miR-27a/b function increases human PINK1 expression. a Schematic diagram of sequence alignment of miR-27a/b and anti-miR-27a/b. Asterisks (*) indicate conserved nucleotides. b Inhibition of endogenous miR-27a/b function increased luciferase activities in HeLa cells. Cells were transfected with the reporter constructs containing the full-length 3′UTR of human PINK1 mRNA with wild-type (WT) or mutated (Mut) seed match sites downstream of Renilla luciferase gene. 48 h post-transfection, luciferase activities were measured (n = 4, t-test). c-f Inhibition of endogenous miR-27a/b increased PINK1 protein levels in HeLa (C-D) and M17 cells (E-F). Cells were transfected with 150 nM of anti-miR-27a/b or anti-control (anti-Ctl). 48 h post-transfection, cells were harvested for Western blot. PINK1 protein level was normalized to corresponding GAPDH level and quantified as a percentage of control (n = 4, t-test). Data are shown as a percentage of control. Values are mean ± SEM (n.s. = non-significant, **p < 0.01, ***p < 0.00)
