ACOT12 and renal fibrosis: Moreover, the restoration of peroxisome proliferator-activated receptor α (PPARα) in Acot12−/−Pparα−/− kidneys with UUO exacerbated lipid accumulation and renal fibrosis, whereas the restoration of Acot12 in Acot12−/−Pparα−/− kidneys with UUO significantly reduced lipid accumulation and renal fibrosis, suggesting that, mechanistically, Acot12 deficiency exacerbates renal fibrosis independently of PPARα.
