We found that 20 mg/kg CA decreased mRNA levels of Grp78, Ire-1, and Perk. Moreover, CA supplementation prevented TM-induced liver injury through changes in lipid accumulation and lipogenesis markers of steatosis (Srebp-1c, Ppar-α, and Fas), and exerted an inhibitory effect on inflammatory (NF-κB, Tnf-α, and Il-6) and apoptotic markers (caspase 3, p53, Bax, and Bcl2), of liver tissue in ER stress mice. This evidence concerns the gene PPARA and steatosis.
