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.

Biochim Biophys Acta. 2006 Mar;1761(3):367-76. Epub 2006 Mar 10.

Sphingosine 1-phosphate (S1P) is a potent mitogenic signal generated from sphingosine by the action of sphingosine kinases (SKs).
The increased SK-1 protein expression is due to stimulated de novo synthesis since cycloheximide inhibited the delayed SK-1 protein upregulation.

Recently sphingosylphosphorylcholine (SPC), sphingosine-1-phosphate (S1P), and C2-ceramide (C2-Cer), sphingolipid containing acetic acid are emerging as melanogenic regulators.
Actinomycin D and cycloheximide, inhibitors of transcription and translation, respectively, inhibited PSL-induced tyrosinase activity and its protein expression showing decrease in melanogenesis, correspondingly.

Upregulation of Mig6 by lipid agonists such as LPA and S1P or actin drugs involved MAL and correlated with decreased activation of EGFR, MAPK/Erk, and c-fos.
