NSD2 and metabolic dysfunction-associated steatohepatitis: Furthermore, no significant abnormalities were detected in fecal output, energy absorption, and expression levels of lipid absorption‐related genes in Nsd2∆IE mice (Figure S3D–F, Supporting Information), providing additional evidence that the alleviation of NASH resulting from NSD2 knockout occurs primarily through the amelioration of intestinal barrier impairment, rather than affecting intestinal energy and lipid absorption.
