STK25 and steatosis: Morphological investigation of H&E-stained liver sections and colorimetric analysis of liver homogenates revealed an equal reduction in micro- and macrovesicular steatosis and TAG content, respectively, in all groups of mice depleted of STK25, MST3, or STK25/MST3 relative to their respective controls, while no difference was observed in hepatic glycogen levels (Fig. 2A–B, Additional File 2: Supplementary Fig. S4).
