| Project Title: | NMR-based lipidomics in Breast Cancer |
| Project Summary: | Recurrent and metastatic breast cancer is frequently treatment resistant. A wealth of evidence suggests that reprogrammed lipid metabolism supports cancer recurrence. Overexpression of the RON and DEK proteins in breast cancer is associated with poor outcome. Both proteins promote cancer metastasis in laboratory models, but effects on lipid metabolite levels remain unknown. To measure RON- and DEK-dependent steady-state lipid metabolite levels, an Nuclear Magnetic Resonance (NMR)-based approach was utilized. The observed differences were then used to identify a lipid metabolism-related gene expression signature that is prognostic of overall survival (OS), distant metastasis free survival (DMFS), post-progression survival (PPS), and recurrence free survival (RFS) in patients with breast cancer. RON loss led to decreased cholesterol and sphingomyelin levels, while DEK loss increased total fatty acid levels and decreased free glycerol levels. Lipid-related genes were then queried to define a signature that predicts breast, ovarian, and lung cancer patient survival. Taken together, RON and DEK differentially regulate lipid metabolism in a manner that predicts and may promote breast cancer metastasis and recurrence. |
