Figure 6. Mitochondrial content in control and PRKN-PD fibroblasts. Mitochondrial content was measured through mtDNA copy number (A), citrate synthase enzymatic activity (B) and mitochondrial network (C). Comparable mitochondrial content was observed between groups in both media. The results are expressed as means and standard error of the mean (SEM). CTL= Control fibroblasts. GAL= 10 mM galactose medium. GLC= 25 mM glucose medium. mtDNA= mitochondrial DNA. PRKN-PD= Parkin-associated PD fibroblasts.
