Quantitative proteomic analysis of co-cultured breast cancer cells

ABSTRACT: Aerobic glycolysis is a hallmark of cancer glucose metabolism. Here we suggest that extracellular vesicles (EVs) originating from cancer cells can modulate glucose metabolism in the recipient cancer cells and induce cell proliferation and aggressive cancer phenotypes. Two breast cancer cell lines with different levels of glycolytic activity, MDA-MB-231 and MCF7, were selected and co-cultured, as the originating and recipient cells. The change in 18F-fluorodeoxyglucose (FDG) uptake of the recipient MCF7 cells was assessed after co-culture with the MDA-MB-231 cells. Proteomics analysis was performed to investigate the changes in the protein expression patterns in the recipient MCF7 cells. FDG uptake by the recipient MCF7 cells was sig-nificantly increased after co-culture with the MDA-MB-231 cells.
