| Outline of Final Research Achievements |
A pleiotropic bioactive lipid mediator, sphingosine-1-phosphate (S1P), produced by sphingosine kinases (SphK1 and SphK2) regulates many physiological and pathological processes. We hypothesized that SphKs regulates cancer cell-specific metabolism, which related to the cancer cell proliferation and survival. Metabolomics profiles of both SphK1KO and SphK2KO breast cancer cells were dramatically changed in the glycolysis pathway and TCA cycle compared to the control cells. Our data suggests that SphKs play an important role in cancer specific metabolism.
