This invention provides the application of agents that inhibit NNMT binding to FGFR1 in the prevention and treatment of tumors. Through mutation analysis and interactomics analysis, it reveals a previously unknown, non-enzyme-dependent role of NNMT in promoting aerobic glycolysis in breast cancer. It discovers that NNMT binds to FGFR1 and acts as a scaffold protein, promoting phosphorylation of PKM2 and LDHA at Y105 and Y10 sites, respectively. By positioning the FGFR1 binding interface to the 140-154 amino acid region of NNMT, this invention designs a competitive cell-penetrating peptide, NNMT-15, which can disrupt the NNMT-FGFR1 interaction, reduce the phosphorylation levels of PKM2 and LDHA, inhibit glycolysis, and suppress proliferation in NNMT-high-expressing cancer cells and cancer-associated fibroblasts. These findings reveal NNMT as a dual-function metabolic regulator and establish the NNMT-FGFR1 scaffolding effect as a targeted therapeutic axis in glycolysis-dependent tumors.
