Abstract
Cellular redox pathways are critical regulators of various biological processes, including the intricate modulation of intracellular signaling pathways. This review explores how major redox enzymes-such as catalase, superoxide dismutases, glutathione peroxidases, thioredoxins, and peroxiredoxins-interact with key cellular signaling pathways, including receptor tyrosine kinase, mTORC1/AMPK, Wnt/β-catenin, TGF-β/SMAD, NF-κB, Hedgehog, Notch, and GPCR signaling. By investigating mechanisms such as ROS-mediated activation, cysteine oxidation, spatial enzyme localization, and phosphatase regulation, we demonstrate the extensive influence of redox balance on cellular signaling dynamics. Understanding these redox-dependent interactions provides insights into pathophysiological conditions ranging from cancer to fibrosis, offering novel therapeutic opportunities.

期刊介绍：
Antioxidants (ISSN 2076-3921), provides an advanced forum for studies related to the science and technology of antioxidants. It publishes research papers, reviews and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
