Application

Sphingomyelin was used as exogenous treatment to study the effect on ATP depletion and Fe-mediated cell injury in human proximal tubular cell line, HK-2 cells.3 It was used to study the effect on Akt phosphorylation in obese mice.4

Biochem/physiol Actions

Sphingomyelin (SM) is a sphingolipid found in the myelin sheath and cell membranes of animals. The regulation of SM content by sphingomyelinase and SM synthase 2 affect the membrane properties and signaling.1 Excess oxysterols result in increased amount of SM and calcium ions that is the main reason for artery blockage and atherosclerosis.2

Other Notes

Contains primarily stearic, nevonic, and lignoceric acids.

Inhibition of thyroid gland function in rats with mercasolil sharply decreased thyroxine and triiodothyronine levels in blood serum and increased acid sphingomyelinase activity and sphingomyelin content in liver. Thyroxine injected into hypothyroid rats normalized the sphingomyelin content, reduced the free
