CYP7A1 and metabolic syndrome: The quantitative PCR results showed that SLKDT extract upregulated the mRNA expressions of peroxisome proliferator‐activated receptor (PPAR)‐α, lipoprotein lipase, carnitine palmitoyltransferase 1, and cholesterol 7 alpha hydroxylase and downregulated PPAR‐γ and CCAAT/enhancer‐binding protein‐alpha mRNA expressions in the obese mouse livers to reduce adipocyte differentiation and fat accumulation, promote fat oxidation, and improve dyslipidemia, thereby inhibiting the immune response and alleviating liver injury.
