Furthermore, in order to investigate how adropin could affect hepatocyte inflammation and injury in nonalcoholic steatohepatitis (NASH), immunohistochemistry using the inflammation markers F4/80, CD45 and MCP-1, and a gene expression analysis for TNFα and IL-6 genes, were performed using liver tissues from adropin knockout C57BL/6J mice and the control wild-type, which were fed a methionine-choline deficient diet [111]. The gene discussed is IL6; the disease is metabolic dysfunction-associated steatohepatitis.
