OPA1 Exon-4b and Exon4 partially recover mitochondrial respiration activity. (A) OCR measurements in WT MEF cells expressing Flag and Opa1 KO cells expressing Flag, OPA1-iso1-Flag, or OPA1-iso5-Flag. (B) Relative ATP production, basal, and maximal respiration using OCR measurements in WT MEF cells expressing Flag and Opa1 KO cells expressing Flag, OPA1-iso1-Flag or OPA1-iso5-Flag (n = 2, biological replicates). WT MEF cells were used as control, whose ATP production, basal, and maximal respiration were normalized to 1. (C) Cellular ATP levels in WT MEF cells expressing Flag and Opa1 KO cells expressing Flag, OPA1-iso1-Flag, or OPA1-iso5-Flag, with or without oligomycin treatment (n = 3, biological replicates). *p < 0.05, **p < 0.01, one-way ANOVA.
