RXFP1 and Hepatic fibrosis: To further explore the clinical relevance of RXFP1 as an antifibrotic target, we examined the expression and distribution of RXFP1 mRNA by in situ hybridization in liver biopsies from patients diagnosed with either early or advanced liver fibrosis due to non-alcoholic steatohepatitis (NASH; n = 2) and autoimmune hepatitis (AIH, n = 2).
