16571380 Huwiler A, Doll F, Ren S, Klawitter S, Greening A, Romer I, Bubnova S, Reinsberg L, Pfeilschifter J: Histamine increases sphingosine kinase-1 expression and activity in the human arterial endothelial cell line EA.hy 926 by a PKC-alpha-dependent mechanism. Biochim Biophys Acta. 2006 Mar;1761(3):367-76. Epub 2006 Mar 10.

The increased SK-1 protein expression is due to stimulated de novo synthesis since cycloheximide inhibited the delayed SK-1 protein upregulation.

Sphingosine kinase (SPHK) and S1P were characterized in INS-1 insulinoma cells and isolated rat islets of Langerhans.
Cytokines increased endogenous S1P biosynthesis in 32P (i)-prelabeled INS-1 cells, and cycloheximide inhibited the response after 8 h, suggesting that protein synthesis mediated the response.
