Niemann Pick type A is a very rare hereditary disease with an incidence 1 in 20000-40000 live birth, which is calassified as a shingolipidoses. The disease is marked by the abnormal accumulation of sphingomyelin in most tissues, secondary to sphingomylinase deficiency. The most clinical manifestations are: Splenohepatomegaly–cherry red maculae-neuropathologic findings . This is a ...

Aberrant Promoter Methylation Profile of Niemann-Pick Type C1 Gene in Cardiovascular Disease

Background: The protein of Niemann-pick type C1 (NPC1) gene promotes the egress of cholesterol from late endosomes and lysosomes to other cellular compartments and contributes to a process known as reverse cholesterol transport. This study aimed to examine whether promoter methylation of NPC1 is associated with risk of cardiovascular disease (CVD). Methods: Fifty CVD patients and 50 healthy sub...

Stem Cells in Niemann-Pick Disease

Neural stem cells are multi-potent and able to self renew to maintain its character throughout the life. Loss of self renewal ability of stem cells prevents recovery or replacement of cells damaged by disease with new cells. The Niemann-Pick type C1 (NPC1) disease is one of the neurodegenerative diseases, caused by a mutation of NPC1 gene which affects the function of NPC1 protein. We reported ...
