| Study Summary | Genomic 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. Here, we conducted integrative transcriptomic and 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-mediated activation of NF-B 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. |

| MS Comments: | Data was acquired on the ID-X in switching polarities at 120000 resolution, with an AGC target of 1e5, and a m/z range of 65 to 1000. MS1 data is acquired in switching polarities for all samples.Data is analyzed in Compound Discoverer 3.3 (CD, ThermoFisher Scientific). A mix of standard of each target was run along the samples and used as the unlabeled reference for the CD labelling workflow. Isotopomer distribution is found in the exchange column, as % of 0 labelled carbon, 1 labelled carbon, 2 labelled carbon, etc. Those are corrected for natural abundance. For the compounds that couldn’t be analyzed by CD, the areas have been extracted with Tracefinder manually. |
