doi: 10.1186/s13020-025-01309-5

Figure Lengend Snippet: As illustrated in the figure, SNS activates hepatic FXR, inhibits the LDs transport protein GPAT4, and modulates the expression of proteins involved in lipolysis and lipophagy, including P62, Beclin1, LC3Ⅰ/Ⅱ, HSL, ATGL, and MAGL. Activation of hepatic FXR inhibits GPAT4 expression. Conversely, when FXR is inhibited, LDs deposition in liver cells worsens, leading to feedback upregulation of GPAT4 expression. The FXR-GPAT4 axis was validated using a DL
