Expression of endothelin system genes increases in mouse experimental model and human AH. (a) Hepatic endothelin system gene expression was confirmed by qPCR from WT and Lcn2−/− mice exposed to CCl4 (n = 4–6). (b) Hepatic endothelin system gene expression from WT and Lcn2−/− mice after 8-week ethanol plus binge exposure. (n = 4 for each group). (c) Human liver biopsies for RNA-sequencing analysis of EDN1, ECE1 and EDNRA expression included multiple etiologies of liver tissues representing control liver (n = 10), NASH (n = 9), HCV (n = 10), compensated cirrhosis (n = 9) and AH (n = 29). (d) Correlation of hepatic LCN2 and EDN1, ECE1 and EDNRA expression in AH patients. (e) Circulating ET1 concentration was quantified by ELISA in serum of patients with multiple etiologies of liver disease. *p < 0.05; **p < 0.01 by one-way ANOVA.
