PPARA and obesity due to melanocortin 4 receptor deficiency: LF-CQPC07 upregulated the mRNA expression of PPAR-α, LPL, CPT1, and CYP7A1 and downregulated the mRNA expression of PPAR-γ and C/EBP-α to inhibit the differentiation and proliferation of adipocytes, promote the β-oxidation of fatty acid and decomposition of triglyceride and cholesterol, thereby ameliorating obesity and dyslipidemia.
