SIPA1L1 and Hepatic fibrosis: Following this discovery protocol, we were able to uncover signal-induced proliferation-associated 1 like 1 (SIPA1L1) as a new non-previously described early biomarker of liver fibrosis in CCl4-treated rats, thus providing scientific rational to design clinical studies assessing the diagnostic and/or prognostic utility of SIPA1L1 in patients with liver fibrosis.
