Abstract:
S1P (sphingosine 1-phosphate) is one of the metabolite products of membrane sphingomyelin, and it plays an important role in formation, transformation and progression of many malignant tumors as well as the regulation of cell proliferation, apoptosis and angiogenesis. Furthermore, S1P plays different roles in regulation of biological behaviors of malignant tumors depending on the types of the cells and S1PR (sphingosine 1-phosphate receptor). For ovarian cancer and colon cancer, S1P improves the growth of tumors cells by S1PR1/S1PR3, but for malignant melanoma, it inhibits the cell growth by S1PR2. There is a difference in the downstream pathways mediated by difficult receptors. This review summarizes the advances in research on the roles of S1P in regulating biological behaviors of tumor cells and different signal pathways of S1P mediated by various receptors.
