Core Tip
Core tip: In portal hypertension patients, endogenous hydrogen sulfide (H2S) levels were significantly lower than those in healthy controls. H2S plasma level reductions correlated with portal vein diameter and Child-Pugh score. In a rabbit hepatic schistosomiasis portal hypertension model, liver tissue H2S concentrations and cystathionine γ-lyase expression were significantly reduced and phosphorylated extracellular signal regulated kinase 1/2 expression gradually increased. Increasing H2S levels led to increased apoptosis of portal vein smooth muscle cells, while B-cell lymphoma-2 (Bcl-2) and Bcl-XL expression decreased. We suggest that H2S prevents portal hypertension though apoptosis induction of otherwise excessive proliferating smooth muscle cells.
