Regulation of hepatic insulin signaling and glucose

We report herein that sphingosine kinase 2 (SphK2), a key enzyme in sphingolipid catabolism, plays a critical role in the regulation of hepatic insulin signaling and glucose homeostasis both in vitro and in vivo. Hepatocyte-specific Sphk2 knockout mice exhibit pronounced insulin resistance and glucose intolerance. Likewise, SphK2-deficient Regulation of hepatic insulin signaling and glucose in the development of type 2 diabetes, which is often asso-ciated with abnormal hepatic lipid regulation. Sphingolipids are a class of essential lipids in the liver, where sphingosine kinase 2 (SphK2) is a key enzyme in their catabolic pathway. However, roles of SphK2 and its related sphingolipids in he-patic insulin resistance remain elusive.

In contrast to prosurvival SPHK1, has a positive effect on intracellular ceramide Siglec-E is a negative regulator of acute pulmonary Mar 14, 2013 · Interestingly, we showed that in neutrophils, siglec-E is constitutively associated with SHP-1 but not with SHP-2. This constitutive association is likely to be important in allowing siglec-E to function as a negative regulator of Syk and p38 MAP kinase and for suppression of neutrophil recruitment in the lung.

Sphingosine 1phosphate as a regulator of osteoclast

Nov 23, 2006 · Sphingosine kinase (SPHK) is a lipid kinase that phosphorylates sphingosine to generate sphingosine 1phosphate (S1P). Two mammalian isoforms, SPHK1 and SPHK2, have been identified.

Sphingosine Kinase 2 (SPHK2) SpringerLink

Sphingosine kinases are a group of enzymes, highly conserved in eukaryotes, which catalyze the phosphorylation of the lipid sphingosine, to produce the bioactive signaling molecule sphingosine-1-phosphate (S1P) (Fig. 1).Sphingosine kinase 2 (SK2), transcribed from the SPHK2 gene located on chromosome 19 (19q13.2), was the second of two functional mammalian sphingosine kinase Sphingosine Kinase 2 in Autoimmune/Inflammatory Disease Jul 01, 2017 · Sphingosine kinase (SK) 2 might be considered an anti-inflammatory enzyme based on studies with Sphk2 / mice. However, there is a compensatory increase in SK1 eion levels in Sphk2 / mice that can function in a proinflammatory context.. Moderately potent SK2 inhibitors exert anti-inflammatory activity in autoimmune/inflammatory disease and fibrotic models.
