Redox regulation of Janus kinase
نویسنده
چکیده
The redox regulation of Janus kinases (JAKs) is a complex subject. Due to other redox-sensitive kinases in the kinome, redox-sensitive phosphatases, and cellular antioxidant systems and reactive oxygen species (ROS) production systems, the net biological outcomes of oxidative stress on JAK-dependent signal transduction vary according to the specific biological system examined. This review begins with a discussion of the biochemical evidence for a cysteine-based redox switch in the catalytic domain of JAKs, proceeds to consider direct and indirect regulatory mechanisms involved in biological experiments, and ends with a discussion of the role(s) of redox regulation of JAKs in various diseases.

Nitric oxide and thiol redox regulation of Janus kinase activity.
The activation of Janus kinases (JAKs) is crucial for propagation of the proliferative response initiated by many cytokines. The proliferation of various cell lines, particularly those of hematopoietic origin, is also modulated by mediators of oxidative stress such as nitric oxide and thiol redox reagents. Herein we demonstrate that nitric oxide and other thiol oxidants can inhibit the autokina...
متن کاملJAK-STAT pathway and JAK inhibitors: a primer for dermatologists
Background: All cellular events depend upon the DNA synthesis and gene expression involving complex interplay between ligands such as interleukins and interferons, with various cell membrane receptors. These ligand-receptors interactions transmit signals within the cell via numerous signal transduction pathways to affect gene expression. Janus kinase/signal transducer and activator of transcrip...
متن کاملInduction of Endothelial NO Synthase by Hydrogen Peroxide via a Ca/Calmodulin-Dependent Protein Kinase II/Janus Kinase 2–Dependent Pathway
We have recently demonstrated that hydrogen peroxide (H2O2) is an extremely potent stimulus of endothelial NO synthase (eNOS) gene expression. The present study was designed to identify the signaling mechanisms mediating this response. Induction of eNOS expression by H2O2 was found to be Ca 21 dependent, inasmuch as it was blocked by BAPTA-AM. Further studies have indicated that Ca/calmodulin-d...

We have recently demonstrated that hydrogen peroxide (H(2)O(2)) is an extremely potent stimulus of endothelial NO synthase (eNOS) gene expression. The present study was designed to identify the signaling mechanisms mediating this response. Induction of eNOS expression by H(2)O(2) was found to be Ca(2+) dependent, inasmuch as it was blocked by BAPTA-AM. Further studies have indicated that Ca(2+)...

Objective(s): The Janus kinase-signal transducers and activators of transcription signaling pathway (JAK/STAT pathway) play an important role in proliferation of breast cancer cells. Previous data showed that inhibition of STAT3 suppresses the growth of breast cancer cells, but the associated mechanisms are not well understood. This study aims to investigate the effect and associated mechanisms...
