Advanced Science, EarlyView.CDGSH iron sulfur domain 1 (CISD1) mitigates oxidative stress by promoting NADH oxidation and Coenzyme Q (CoQ) reduction. Under chronic stress, elevated CISD1 expression in microglia enhances NAD⁺ production, thereby increasing GAPDH activity and glycolytic flux, while reducing ATP synthesis by inhibiting proton transfer from mitochondrial complexes I ...

Effects of heme oxygenase isozymes on Leydig cells steroidogenesis [PDF]
, 2009 In the present study, we demonstrate the expression of heme oxygenase (HO) isozymes, HO-1 and HO-2 (listed as HMOX1 and HMOX2 in the MGI Database), in MA-10 Leydig tumor cells and its effect on steroidogenesis. The well-known HO inducer, hemin, increased

Advanced Science, EarlyView.This study develops gallium‐doped V2C MXene nanozymes (Ga‐V2C) to treat acetaminophen‐induced liver injury through multi‐death pathway blockade and hepatocyte regeneration. Unlike conventional single‐target therapies like N‐acetylcysteine, Ga‐V2C nanozymes enable oxidative stress suppression, apoptosis, and ferroptosis inhibition, and enhanced ...

Advanced Science, EarlyView.BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Protective Effects of Inducible HO-1 on Oxygen Toxicity in Rat Brain Endothelial Microvessel Cells [PDF]
Endocrinology and Metabolism, 2014 BackgroundReperfusion in ischemia is believed to generate cytotoxic oxidative stress, which mediates reperfusion injury. These stress conditions can initiate lipid peroxidation and damage to proteins, as well as promote DNA strand breaks.

Oxygen Activation by Mononuclear Mn, Co, and Ni Centers in Biology and Synthetic Complexes [PDF]
, 2017 The active sites of metalloenzymes that catalyze O2-dependent reactions generally contain iron or copper ions. However, several enzymes are capable of activating O2 at manganese or nickel centers instead, and a handful of dioxygenases exhibit activity ...

Advanced Science, EarlyView.Esketamine and ketamine are widely used for perioperative analgesia and anesthesia. Despite their established roles in analgesia, sedation, and anesthesia, as well as emerging antidepressant, anti‐tumor, and anti‐inflammatory effects, their clinical use is limited due to side effects and addiction potential.

Oxidative stress markers induced by hyperosmolarity in primary human corneal epithelial cells. [PDF]
PLoS ONE, 2015 Oxidative stress has been known to be involved in pathogenesis of dry eye disease. However, few studies have comprehensively investigated the relationship between hyperosmolarity and oxidative damage in human ocular surface.
