CYP7A1 and metabolic dysfunction-associated steatotic liver disease: Similarly, overexpression of CYP7A1 in a mice MASLD model effectively alleviated hepatic steatosis via activation of the hepatic BAs signaling pathway, inhibition of lipid synthesis, and decreased fatty acid uptake39-41, which was consistent with the downregulation of genes related to fatty acid transport and synthesis in Piezo1ΔIEC mice liver in this study.
