Core Tip
Core Tip: Spontaneous portosystemic shunts (SPSS) are strongly associated with adverse outcomes in hepatitis B virus-related cirrhosis, including more frequent decompensation and higher mortality. By integrating multicenter clinical data with proteomic, metabolomic, and animal studies, this work identifies dysregulation of the AKT-eNOS-nitric oxide pathway as a potential mechanism underlying SPSS formation. Pharmacologic activation of AKT with SC79 reduced the incidence of SPSS and alleviated cirrhosis severity in vivo, suggesting that this pathway may represent a promising therapeutic target in cirrhosis with portal hypertension.
