PPARGC1A and acute kidney injury: Formoterol, a selective β(2)-AR agonist, significantly increased the copy number of mtDNA and upregulated the expression of PGC-1α and several other genes involved in the mitochondrial electron transport chain in an I/R-induced AKI mouse model [594], thereby accelerating the recovery process of podocyte from glomerular injury and improving brain function following traumatic brain injury [682, 683].
