Study TitleInvestigation of FGFR signaling controlled metabolism in FGFR2-fusion+ intrahepatic cholangiocarcinoma
Study SummaryGenomic alterations that activate FGFR2 are common in intrahepatic cholangiocarcinoma (ICC) and confer sensitivity to treatment with FGFR inhibitors. However, the depth and duration of responses are often limited. Elucidating the FGFR2-driven oncogenic program and the adaptions to FGFR inhibition is needed to gain insight into the biology of these tumors and inform future therapeutic development. Here, we conducted metabolomic analysis of patient-derived models to define the pathways that fuel tumor growth downstream of oncogenic FGFR2 signaling in ICC and to uncover compensatory mechanisms associated with pathway inhibition. We find FGFR2-fusion+ ICC maintains a highly glycolytic phenotype in FGFR2+ ICC. Conversely, FGFR inhibition blocks glucose uptake and glycolysis, while inciting a series of adaptive changes. Thus, we show that glycolysis is a key downstream effector of oncogenic FGFR2 signaling in ICC, and that pronounced metabolic reprogramming in response to FGFR inhibition confers new targetable vulnerabilities.

Project Title:FGFR inhibition blocks NF-ĸB-dependent glucose metabolism and confers metabolic vulnerabilities in cholangiocarcinoma
Project Summary:Genomic alterations that activate FGFR2 are common in intrahepatic cholangiocarcinoma (ICC) and confer sensitivity to FGFR inhibitor treatment. However, the depth and duration of responses are often limited. Here, we conducted integrative transcriptomics, metabolomics, and phosphoproteomics analysis of patient-derived models to define the pathways that fuel tumor growth downstream of oncogenic FGFR2 signaling in ICC and to uncover compensatory mechanisms associated with pathway inhibition. We find FGFR2-mediated activation of NF-kB maintains a highly glycolytic phenotype. Conversely, FGFR inhibition blocks glucose uptake and glycolysis while inciting a series of adaptive changes, including switching fuel source utilization to favor fatty acid oxidation and increasing mitochondrial fusion and autophagy. Accordingly, FGFR inhibitor efficacy is potentiated by combined mitochondrial targeting, an effect enhanced in xenograft models by intermittent fasting. Thus, we show that oncogenic FGFR2 signaling drives NF-kB-dependent glycolysis in ICC and that metabolic reprogramming in response to FGFR inhibition confers new targetable vulnerabilities.
