PPARA and Disorder of lipid metabolism: Specifically, LLPK intervenes in biological processes such as lipogenesis, fatty acid oxidation, and fatty acid transport in mice livers by regulating the expression of key downstream factors of PPARα (Scd1, Acox1, Acaa1b, Slc27a1, Acsl1, and Ehhadh), thus improving lipid metabolic disorders (Figure 7).
