Reduced sphingosine kinase-1 and enhanced sphingosine 1-phosphate lyase expression demonstrate deregulated sphingosine 1-phosphate signaling in Alzheimer’s disease
BACKGROUND The accumulation of beta amyloid (Aβ) peptides, a hallmark of Alzheimer's disease (AD) is related to mechanisms leading to neurodegeneration. Among its pleiotropic cellular effects, Aβ accumulation has been associated with a deregulation of sphingolipid metabolism. Sphingosine 1-phosphate (S1P) derived from sphingosine is emerging as a critical lipid mediator regulating various biolo...
متن کاملStructure and function of sphingosine-1-phosphate lyase, a key enzyme of sphingolipid metabolism.
Sphingosine-1-phosphate lyase (SPL), a key enzyme of sphingolipid metabolism, catalyzes the irreversible degradation of sphingoid base phosphates. Its main substrate sphingosine-1-phosphate (S1P) acts both extracellularly, by binding G protein-coupled receptors of the lysophospholipid receptor family, and inside the cell, as a second messenger. There, S1P takes part in regulating various cellul...

Inflammatory bowel disease is associated with an increased risk of colorectal cancer. Colitis-associated cancer is a classical inflammation-driven cancer in which constitutive NFκB and STAT3 activation drive tumorigenesis. Recent findings published by Liang et al. in Cancer Cell demonstrate that sphingosine kinase 1 (SphK1)-mediated upregulation of sphingosine-1-phosphate (S1P) drives a persist...
متن کاملSphingosine 1-phosphate signalling.
Sphingosine 1-phosphate (S1P) is a lipid mediator formed by the metabolism of sphingomyelin. In vertebrates, S1P is secreted into the extracellular environment and signals via G protein-coupled S1P receptors to regulate cell-cell and cell-matrix adhesion, and thereby influence cell migration, differentiation and survival. The expression and localization of S1P receptors is dynamically regulated...

Besides their structural role, sphingolipids including Sphingosine-1phosphate (S1P) have drawn attention as bioactive sphingolipid signaling molecules involved in the regulation of several processes, including cell growth, differentiation, survival, migration or immune response. It is now well established that S1P is involved in the onset or the progression of pathological conditions such as ca...
