Pathological and physiological significance of ERRα. (A) Regulation of mitochondrial energy production and oxidative phosphorylation, hepatic metabolism of glucose and lipids, distinctive control of type 2 diabetes in liver and skeletal muscles and implication as potential therapeutic target in the treatment of glucose excess, obesity and diabetes. (B) Significance of ERRs mediated signaling control in Krebs (TCA) cycle and oxidative phosphorylation, in which ERRα and ERRγ isoforms serve as central regulatory pillars of metabolic genes and cellular energy metabolism. ERRβ,has been reported to be vital for maintenance of embryonic stem cell pluripotency (110).
