Abstract

Non-alcoholic fatty liver disease (NAFLD) is characterized by excessive accumulation of lipids in hepatocytes. Among NAFLD patients, in 25% of them this disease progress to nonalcoholic steatohepatitis, which is characterized additionally by the development of inflammation and fibrosis of liver. Currently, it is estimated that 24% of the world’s population suffers from NAFLD. MCPIP1 protein is an RNase described as a negative regulator of inflammation. Also, MCPIP1 plays a role in lipid metabolism because it inhibits the process of adipogenesis and mice with a deletion of Zc3h12a gene are characterized by dyslipidemia and reduced body fat content. In the case of ischemia-reperfusion injury in liver, MCPIP1 is protective against the inflammation and damage of this organ. Lipid accumulation by hepatocytes is associated with a decrease of Mcpip1 level. In addition, MCPIP1 may influence the PPARγ-mediated lipogenesis process. Presence of Mcpip1 in both myeloid leukocytes and liver epithelial cells is crucial for the maintenance of liver homeostasis.
