The Role of Nrf2 and PPARγ in the Improvement of Oxidative Stress in Hypertension and Cardiovascular Diseases
2020
Reactive oxygen species are an important element of redox regulation in cells and tissues. During physiological processes, molecules undergo chemical changes caused by reduction and oxidation reactions. Free radicals are involved in interactions with other molecules, leading to oxidative stress. Oxidative stress works two ways depending on the levels of oxidizing agents and products. Excessive action of oxidizing agents damages biomolecules, while a moderate physiological level of oxidative stress (oxidative eustress) is necessary to control life processes through redox signaling required for normal cellular operation. High levels of reactive oxygen species (ROS) mediate pathological change…

Molecular evolution of antioxidant and hypoxia response in long-lived, cancer-resistant blind mole rats: The Nrf2-Keap1 pathway.
2015
The Nrf2-Keap1 pathway is crucial for the cellular antioxidant and hypoxia response in vertebrates. Deciphering its modifications in hypoxia-adapted animals will help understand its functionality under environmental stress and possibly allow for knowledge transfer into biomedical research. The blind mole rat Spalax, a long-lived cancer-resistant rodent, lives in burrows underground and is adapted to severely hypoxic conditions. Here we have conducted a bioinformatical survey of Spalax core genes from the Nrf2-Keap1 pathway on the coding sequence level in comparison to other hypoxia-tolerant and -sensitive rodents. We find strong sequence conservation across all genes, illustrating the pathw…
Redox regulation of genome stability by effects on gene expression, epigenetic pathways and DNA damage/repair
2015
Reactive oxygen and nitrogen species (e.g. H2O2, nitric oxide) confer redox regulation of essential cellular signaling pathways such as cell differentiation, proliferation, migration and apoptosis. In addition, classical regulation of gene expression or activity, including gene transcription to RNA followed by translation to the protein level, by transcription factors (e.g. NF-κB, HIF-1α) and mRNA binding proteins (e.g. GAPDH, HuR) is subject to redox regulation. This review will give an update of recent discoveries in this field, and specifically highlight the impact of reactive oxygen and nitrogen species on DNA repair systems that contribute to genomic stability. Emphasis will be placed …
