| pubmed-article:10670688 | pubmed:abstractText | Ceramide, ceramide-1-phosphate (C1P) sphingosine (SPH) and sphingosine-1-phosphate (S1P) effects on proliferation and extracellular-signal regulated kinases, ERKs (also known as MAPKs), activation were investigated in human and rat osteoblastic cells. MAPK activation was sphingolipid-specific in cells from both species. In human osteoblastic cells, S1P and C1P markedly stimulated ERK2 phosphorylation with a slight increase in phosphorylation of ERK1. SPH nor ceramide induced phosphorylation of either ERK isoform. In rat osteoblastic cells, SIP, ceramide and SPH stimulated phosphorylation of both isoforms. C1P did not induce phosphorylation of ERK1 but produced a mild increase in phosphorylation of ERK2. In human cells, only S1P significantly (P<0.05) increased osteoblastic cell proliferation, while in the rat cells all four sphingolipids significantly (P<0.05) induced proliferation. The calcium channel blocker verapamil blocked (P<0.05) these effects in both cell types. The MAPK inhibitor, PD98059, inhibited (P<0.05) the mitogenic effect of SIP in human cells. In rat cells, PD98059 effects were less substantial but significant for S1P and C1P. This study demonstrates that sphingolipids are mitogens for both human and rat osteoblastic cells with the MAPK pathway and calcium mediating in part these effects in a species specific manner. | lld:pubmed |
