| Study Title | Metabolomics analysis of AsPC-1 PDAC cells treated with Porcupine inhibitor (LGK974) |
| Study Summary | WNT signaling promotes pancreatic ductal adenocarcinoma (PDAC) through diverse effects on proliferation, differentiation, survival, and stemness. A subset of PDAC with inactivating mutations in ring finger protein 43 (RNF43) have growth dependency on autocrine WNT ligand signaling, which renders them susceptible to porcupine inhibitors (PORCNi) that block WNT ligand acylation and secretion. For this study, non-targeted metabolomic analyses were performed to explore the therapeutic response of RNF43-mutant PDAC to the PORCNi LGK974. AsPC-1 (RNF43-mutant) PDAC cells were treated with 25 nM LGK974 to explore stable isotope-resolved metabolomics with uniform 1, D-glucose [U13-C6] labeling. |

| MS Comments: | Metabolites were detected and quantified as area under the curve based on retention time and accurate mass (≤ 3 p.p.m.) using the TraceFinder 3.1 (Thermo Fisher Scientific). Relative amounts of metabolites between various conditions, as well as percentage of [13C6] glucose labeling, were calculated and corrected for naturally occurring 13C abundance. |
