Description :
Sphingosine kinase (SPHK) is an important enzyme in the sphingolipid metabolic pathway. SPHKs phosphorylate D-erythro-sphingosine to yield sphingosine-1-phosphate (S1P). To date, two isoforms of SPHK, SPHK 1 and SPHK 2, have been identified and characterized from mammalian cells. Among them, SPHK 1 has been implicated to play a role in signalling pathways in mast cells and in TNF-α-triggered responses of fibroblasts and epithelial cells. Recent findings also indicate that SPHK 1 mRNA levels are increased in a variety of human tumors. Brain tumors with high SPHK 1 expression correlated with poor survival of patients and high expression of SPHK 1 appears to be an oncogenic event required for erythroleukaemia progression. Thus SPHK is a potential therapeutic target for the control of cancer and inflammation.
