PKM and cancer: Some gene expression differences between cell lines were reflected in patients; genes manifesting equivalent profiles were DUSP4, SLC36A1, EPB41L1, PNMA2, YPEL3, SEC11C, FGGY, LSM2, IGFBP7, STOML2, PKM, and SYNPO. Their contribution to biological processes seems to clarify the cancer-related events that determined longer or shorter survival.
