Solid-phase synthesis of a small combinatorial library of dihydroceramide analogues as mixtures of erythro and threo diastereomers is described. Some dihydroceramide analogues cause growth arrest and apoptosis in a dose-dependent manner in human alveolar epithelial cells. This activity is likely

The present study reports the effect of ceramide generated by hydrolysis of membrane sphingomyelin with bacterial sphingomyelinase (SMase) and of cell-permeable ceramide analogues on the expression of manganese superoxide dismutase (MnSOD). Incubation of the rat primary astrocytes with SMase led
Metabolism of macrophage (MO) membrane phospholipids produces key mediators of inflammation and major second messengers that modulate inflammatory responses during sepsis. Sphingomyelin is a major class of phospholipid that releases ceramide and sphingosine. This study was designed to investigate the
Muscle atrophy associated with various pathophysiological conditions represents a major health problem, because of its contribution to the deterioration of patient status and its effect on mortality. Although the involvement of pro-inflammatory cytokines in this process is well recognized, the
Ceramide, a bioactive lipid and signaling molecule associated with cardiovascular disease, is known to activate extracellular signal regulated kinases 1 and 2 (ERK1/2). Here, we determined that the effect of ceramide on ERK1/2 is mediated by ceramide signaling on an
