Sphingolipid Regulation of Tissue Fibrosis
Bioactive sphingolipids, such as sphingosine 1-phosphate (S1P), dihydrosphingosine 1-phosphate (dhS1P) and ceramide, regulate a diverse array of cellular processes. Many of these processes are important components of wound-healing responses to tissue injury, including cellular apoptosis, vascular leak, fibroblast migration, and TGF-β signaling. Since over-exuberant or aberrant wound-healing res...
متن کاملRegulation of Tissue Fibrosis by the Biomechanical Environment
The biomechanical environment plays a fundamental role in embryonic development, tissue maintenance, and pathogenesis. Mechanical forces play particularly important roles in the regulation of connective tissues including not only bone and cartilage but also the interstitial tissues of most organs. In vivo studies have correlated changes in mechanical load to modulation of the extracellular matr...
متن کاملRegulation of PP2A by Sphingolipid Metabolism and Signaling
Protein phosphatase 2A (PP2A) is a serine/threonine phosphatase that is a primary regulator of cellular proliferation through targeting of proliferative kinases, cell cycle regulators, and apoptosis inhibitors. It is through the regulation of these regulatory elements that gives PP2A tumor suppressor functions. In addition to mutations on the regulatory subunits, the phosphatase/tumor suppressi...
متن کاملSterol-dependent regulation of sphingolipid metabolism in Saccharomyces cerevisiae.
We had previously isolated the temperature-sensitive erg26-1 mutant and characterized the sterol defects in erg26-1 cells (Baudry, K., Swain, E., Rahier, A., Germann, M., Batta, A., Rondet, S., Mandala, S., Henry, K., Tint, G. S., Edlind, T., Kurtz, M., and Nickels, J. T., Jr. (2001) J. Biol. Chem. 276, 12702-12711). We have now determined the defects in sphingolipid metabolism in erg26-1 cells...
متن کاملRegulation of epidermal sphingolipid synthesis by permeability barrier function.
A mixture of sphingolipids, cholesterol, and free fatty acids forms the intercellular membrane bilayers of the stratum corneum which are presumed to regulate epidermal barrier function. Prior studies have shown that both cholesterol and fatty acid synthesis are rapidly regulated by epidermal barrier requirements. In contrast, the importance of sphingolipids in barrier function has not been dire...
