Linking the ceramide synthases (CerSs) 4 and 5 with apoptosis, endometrial and colon cancers.
Dlamini et al., Johannesburg, South Africa. In Exp Mol Pathol, Jun 2015
Although knowledge of the role that CerSs play in cancer biology is advancing, the precise roles of distinct CerSs in different cancers are not yet fully understood, especially the roles of CerS4 and CerS5 in endometrial and colon cancers.

Perera et al., College Park, United States. In Biochim Biophys Acta, Feb 2015
Moreover, mitochondria isolated from cells overexpressing the ceramide synthase responsible for the production of C16-ceramide (CerS5) are permeabilized faster upon the exogenous addition of C16-ceramide whereas they are resistant to permeabilization with added C24-ceramide.
Sortilin deficiency improves the metabolic phenotype and reduces hepatic steatosis of mice subjected to diet-induced obesity.
Zvibel et al., Tel Aviv-Yafo, Israel. In J Hepatol, 2015
Sortilin deficiency led to attenuated hepatic steatosis, reduced expression of genes involved in lipogenesis, ceramide synthesis and inflammatory cytokine production and reduced activity of ceramide synthase 5/6 (CerS5/6).
Ceramide synthases CerS4 and CerS5 are upregulated by 17β-estradiol and GPER1 via AP-1 in human breast cancer cells.
Grösch et al., Frankfurt am Main, Germany. In Biochem Pharmacol, 2015
Only the activities of CerS4 and CerS5 promoter Luc constructs, as well as CerS2- and CerS5-3'-UTR Luc constructs increased after estradiol treatment in MCF-7 cells, and this could be inhibited by the anti-estrogen fulvestrant.
Impact of insulin deprivation and treatment on sphingolipid distribution in different muscle subcellular compartments of streptozotocin-diabetic C57Bl/6 mice.
Nair et al., Rochester, United States. In Am J Physiol Endocrinol Metab, 2014
The alternations were accompanied by an increase in protein expression in LCFa-CoA and Cer synthesis (FATP1/ACSVL5, CerS1, CerS5), a decrease in the expression of genes implicated in muscle insulin sensitivity (GLUT4, GYS1), and inhibition of insulin signaling cascade by Aktα and GYS3β phosphorylation under acute insulin stimulation.
Limited density of an antigen presented by RMA-S cells requires B7-1/CD28 signaling to enhance T-cell immunity at the effector phase.
Zhang et al., New Orleans, United States. In Plos One, 2013
Our experiments in vivo and in vitro indicated that reactivity of antigen-specific monoclonal and polyclonal T-cell effectors against a Lass5 epitope presented by RMA-S cells is increased when the cells expressed B7-1.
Ceramide accumulation in L6 skeletal muscle cells due to increased activity of ceramide synthase isoforms has opposing effects on insulin action to those caused by palmitate treatment.
Schmitz-Peiffer et al., Australia. In Diabetologia, 2013
METHODS: CerS isoforms CerS1, CerS2, CerS4, CerS5 and CerS6 were overexpressed in L6 myotubes using adenovirus, and cells were treated with palmitate and stimulated with insulin.
Ceramide synthases expression and role of ceramide synthase-2 in the lung: insight from human lung cells and mouse models.
Futerman et al., Indianapolis, United States. In Plos One, 2012
We now show that C24- and C16-ceramides are the most abundant lung ceramide species, paralleled by high expression of their synthetic enzymes, ceramide synthase 2 (CerS2) and CerS5, respectively.
Modulation of ceramide synthase activity via dimerization.
Futerman et al., Israel. In J Biol Chem, 2012
Under suitable conditions, high M(r) CerS complexes can be detected by Western blotting, and various CerS co-immunoprecipitate. CerS5 activity is inhibited in a dominant-negative fashion by co-expression with catalytically inactive CerS5, and CerS2 activity is enhanced by co-expression with a catalytically active form of CerS5 or CerS6.
Acyl chain specificity of ceramide synthases is determined within a region of 150 residues in the Tram-Lag-CLN8 (TLC) domain.
Futerman et al., Israel. In J Biol Chem, 2012
We now explore CerS structure-function relationships by constructing chimeric proteins combining sequences from CerS2, which uses C22-CoA for ceramide synthesis, and CerS5, which uses C16-CoA.
D,L-Threo-1-phenyl-2-decanoylamino-3-morpholino-1-propanol (DL-PDMP) increases endoplasmic reticulum stress, autophagy and apoptosis accompanying ceramide accumulation via ceramide synthase 5 protein expression in A549 cells.
Yamane et al., Tokyo, Japan. In Biochimie, 2011
Since an increase in LASS5 protein expression in subcellular fraction occur in preference to the variation of LC3B-II protein expression via CHOP expression after the addition and Cer accumulation induced by the addition contributes to ER stress, it is thought that an elevation of Cer synthase activity via LASS5 protein expression associate to autophagy via CHOP expression (ER stress) with the addition.

Hannun et al., Charleston, United States. In J Biol Chem, 2007
accumulation of C(16)-ceramide in mitochondria formed from the protein kinase C-dependent salvage pathway results at least in part from the action of longevity-assurance homologue 5, and the generated ceramide modulates the p38 cascade via PP1
