In this study, we examined the role of autophagy in the initiation of lipid increases in renal epithelial HK2 cells. We found that trivalent chromium [Cr(III)] induced autophagy by activating sphingomyelin phosphodiesterase 2 (SMPD2). SMPD2 increases levels of ceramide and other lipids.

The mouse mutation fragilitas ossium (fro) leads to a syndrome of severe osteogenesis and dentinogenesis imperfecta with no detectable collagen defect. Positional cloning of the locus identified a deletion in the gene encoding neutral sphingomyelin phosphodiesterase 3 (Smpd3) that led to complete loss of enzymatic activity.

Type A and B forms of Niemann-Pick disease (NPD) are lipid storage disorders caused by deficient activity of the enzyme acid sphingomyelinase (aSMase) and the resulting accumulation of sphingomyelin in tissues. In the present study, we investigated two family members who had been diagnosed with Type B NPD and who had a severe decrease in plasma high ...

Niemann-Pick disease (NPD) is a lysosomal storage disorder that results from the deficiency of a lysosomal enzyme, acid sphingomyelinase. Niemann-Pick disease type A and B is caused by mutations in the sphingomyelin phosphodiesterase gene (SMPD1) coding for ASM.

Radiation-Induced Nephrotoxicity: Role of Sphingomyelin Phosphodiesterase Acid-like 3b
International Journal of Radiation Oncology Biology PhysicsRadiation nephropathy (RN) can be a significant late complication after radiation therapy (RT) for abdominal and paraspinal tumors. The mechanisms for the development of RN are thought to involve disruption of podocyte function, leading to podocyte cell death and, finally, impaired renal function.

AbstractAim: Sphingomyelin phosphodiesterase 1 (SMPD1) plays an essential role in initiating the female germ cell death signal. To evaluate whether RNA interference has potential as a new approach in germ cell protection, we tested the effect of SMPD1 knockdown on human granulosa cells in vitro.Methods: We designed and synthesized three small ...

Sphingomyelin phosphodiesterase acid-like 3A (SMPDL3A) is a recently identified phosphodiesterase, which is a secreted N-linked glycoprotein. SMPDL3A is highly homologous to acid sphingomyelinase (aSMase), but unlike aSMase cannot cleave sphingomyelin. Rather, SMPDL3A hydrolyzes nucleotide tri- and diphosphates and their derivatives.

Uncontrolled cardiac fibrosis following myocardial infarction (MI) is a critical pathological change leading to heart failure. Current pharmacotherapies are limited by unsatisfactory efficacy and undesired systemic side effects. Astaxanthin (ASX) is a natural carotenoid with strong antioxidant and anti-inflammatory activities.
