Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage. Disturbances in the normal redox state of cells can cause toxic effects through the production of peroxides and free radicals that damage all components of the cell, including pr… WebFeb 3, 2024 · Oxidative stress and calcium dysregulation by palmitate in type 2 diabetes Luong Dai Ly, Shanhua Xu, Seong-Kyung Choi, Chae-Myeong Ha, Themis Thoudam, Seung-Kuy Cha, Andreas Wiederkehr, Claes B...
WebApr 26, 2024 · Pathophysiology of oxidative stress. Free radicals are highly reactive atoms or molecules with one or more unpaired electron(s) in their external shell and can be formed when oxygen interacts with certain molecules. 1 These radicals can be produced in cells by losing or accepting a single electron, therefore, behaving as oxidants or reductants. 2 The … WebMar 27, 2024 · In addition, PLB-induced G2/M cell cycle arrest, oxidative stress, and DNA damage was detected, which could be almost blocked by NAC pretreatment. PLB could trigger a DNA damage response by activating cell cycle checkpoints such as ATM, checkpoint kinase 1 (Chk1), checkpoint kinase 2 (Chk2) and p53. Meanwhile, the key …
WebJul 5, 2024 · Oxidative stress is a phenomenon caused by an imbalance between production and accumulation of oxygen reactive species (ROS) in cells and tissues and the ability of a biological system to detoxify these reactive products.
