Abstract Acute-on-chronic liver failure (ACLF) is characterized predominantly by non-apoptotic forms of hepatocyte cell death. Necroptosis a form programmed lytic death in which receptor interacting protein kinase (RIPK) 1, RIPK3 and phosphorylated mixed lineage domain-like (pMLKL) are key components. This study was performed to determine the role RIPK1 mediated ACLF. plasma levels hepatic expression RIPK1, RIPK3, pMLKL were measured healthy volunteers, stable patients with cirrhosis,...

Abstract FGF19/FGFR4 autocrine signaling is one of the main targets for multi-kinase inhibitors (MKIs). However, molecular mechanisms underlying in antitumor effects to MKIs hepatocellular carcinoma (HCC) remain unclear. In this study, impact FGFR4/ERK inhibition on HCC following MKI treatment was analyzed vitro and vivo assays. Serum FGF19 patients treated using MKIs, such as sorafenib (n = 173) lenvatinib 40), measured by enzyme-linked immunosorbent assay. Lenvatinib strongly inhibited...
