Dynamic Redox Regulation of IL-4 Signaling
Quantifying the magnitude and dynamics of protein oxidation during cell signaling is technically challenging. Computational modeling provides tractable, quantitative methods to test hypotheses of redox mechanisms that may be simultaneously operative during signal transduction. The interleukin-4 (IL-4) pathway, which has previously been reported to induce reactive oxygen species and oxidation of...
متن کاملRecent advances in lymphocyte signaling and regulation.
The antigen receptor signaling pathway in lymphocytes is vital to their development and biological function. Recent studies have shown that protein tyrosine kinases and phosphatases are essential components in this receptor signaling pathway and therefore, are critical for the development of mature and functionally competent lymphocytes. The Src kinase family of protein tyrosine kinases coordin...
متن کاملRegulation of inflammation and redox signaling by dietary polyphenols.
Reactive oxygen species (ROS) play a key role in enhancing the inflammation through the activation of NF-kappaB and AP-1 transcription factors, and nuclear histone acetylation and deacetylation in various inflammatory diseases. Such undesired effects of oxidative stress have been found to be controlled by the antioxidant and/or anti-inflammatory effects of dietary polyphenols such as curcumin (...
متن کاملRedox regulation of auxin signaling and plant development in Arabidopsis.
Thioredoxin (NTR/TRX) and glutathione (GSH/GRX) are the two major systems which play a key role in the maintenance of cellular redox homeostasis. They are essential for plant development, cell division or the response to environmental stresses. In a recent article, we studied the interplay between the NADP-linked thioredoxin and glutathione systems in auxin signaling genetically, by associating...
متن کاملRedox Regulation of Pka Signaling: Kinase versus Phosphatase Inactivation
Many components of cellular signaling pathways are sensitive to regulation by oxidation and reduction. Previously, we described the inactivation of cAMP dependent protein kinase (PKA) by direct oxidation of a reactive cysteine in the activation loop of the kinase. In the present study, we demonstrate that in Hela cells PKA activity follows a biphasic response to thiol oxidation. Under mild oxid...
