Integrated multi-omics analysis of liver metabolic dysregulation in ACE2 knockout mice

This study reveals the molecular mechanisms of liver metabolic dysregulation in ACE2 knockout (ACE2KO) mice through multi-omics analysis. ACE2 deficiency exacerbates lipid accumulation, disrupts RAS balance, and induces hepatocyte injury and inflammation. Integrated multi-omics analysis identified numerous differentially expressed genes, proteins, and metabolites, highlighting the PPAR signaling pathway as a central regulatory hub. ACE2 deletion also impairs detoxification and antioxidant balance, creating a self-reinforcing oxidative injury cycle. These findings provide new insights into the mechanisms and therapeutic targets of ACE2-related liver diseases.
