Abstract Introduction: Triple Negative Breast Cancer (TNBC) exhibits increased glycolysis, known as the Warburg effect. Recent research, including our own Nanostring nCounter studies, identify β-catenin as an oncoprotein linked to elevated glycolysis in TNBC tumors. Our current research explores the impact of β-catenin inhibitors on glycolysis in TNBC cell lines and an in vivo CDX model. Method: We employed immunohistochemistry to assess 98 TNBCs for the presence of β-catenin, PFKP, LDH-A, and MCT1 proteins, exploring their correlation with clinicopathological factors. In in-vitro experiments using MDA-MB-231, MDA-MB-468, and 4T1 cell lines, we investigated how β-catenin inhibitors (XAV939 Part 1 (Regular Abstracts) ; 2024 Apr 5-10; San Diego, CA.
