Sex- and hepatocyte PPARγ-dependent effects of an obesogenic dietary approach to induce MASH with fibrosis in mice
This study demonstrates that a specific high-fat, high-cholesterol, and fructose-supplemented diet successfully induces obesity and MASLD in both male and female mice, but progression to MASH with fibrosis occurs exclusively in males through a hepatocyte PPARγ-dependent mechanism involving the downregulation of methionine metabolism.
