B Down-regulating MICAL2PV enhances mitochondrial infiltration. Mitochondrial infiltration index was quantified as the ratio of the radial distance from the nucleus to the furthest mitochondria and the radial distance from the nucleus to the plasma membrane. Fifty cells were quantified for each group. Data information: data were analyzed using one-way ANOVA with Bonferroni post-test and shown as mean ± SEM; * P < 0.05, *** P < 0.001. Three independent experiments were conducted.
