| الوصف: | Monocyte-chemoattractant protein-induced protein 1 (MCPIP1, or Regnase-1) is an endoribonuclease that degrades translationally active mRNA molecules. MCPIP1 is mostly known for its anti-inflammatory actions, but it is also an important regulator of adipogenesis and lipid metabolism. Its overexpression impairs adipogenesis by reducing mRNA levels of C/EBP$\beta$ and PPAR$\gamma$, key transcription factors regulating this process. Although adipocytes overexpressing MCPIP1 are characterised by impaired glucose uptake, the function of MCPIP1 in hepatocyte metabolism remains unknown. In this study, conditional deletion of Zc3h12a in murine liver epithelial cells was used to characterise the role of Mcpip1 in adaptation to 24-hour food restriction. We found that Mcpip1 deficiency in liver epithelial cells ($Mcpip^{1fl/fl}Alb^{Cre} mice$) resulted in higher blood glucose levels in response to fasting in comparison to $Mcpip1^{fl/fl}$ counterparts. Hepatic proteome analysis showed 26 down-regulated and 117 up-regulated proteins in $Mcpip1^{fl/fl}Alb^{Cre}$ animals that were involved in cellular adhesion, extracellular matrix and metabolic processes. In conclusion, our studies provide new insight into the hepatic function of Mcpip1 and its involvement in metabolic control. |
