Summary: Reactive oxygen species (ROS) play important roles in health and disease, with both beneficial and harmful effects. Different sources of ROS have different roles in various pathologies. NOX1 is associated with hypertension through ROS production, making it a promising therapeutic target. NOX2 and NOX4 produce hydrogen peroxide, influencing cellular processes. Increased ROS production from NOX5 contributes to atherosclerosis.

Summary: The study found that oxidized HDL lipids were not significantly associated with lipoprotein subclass lipid concentrations and composition after adjusting for certain factors, while oxidized LDL lipids were associated with multiple markers of lipoprotein subclass lipid concentrations and composition. Additionally, HDL and LDL subclass measures, such as phospholipid and triglyceride composition, were directly associated with oxidized LDL lipids, while cholesterol ester and free cholesterol composition in HDL and LDL were inversely associated. These results suggest that LDL oxidation may play a role in atherogenesis.

Summary: The conversion of human SW872 preadipocytes to mature adipocytes involves time-dependent changes in differentiation markers' expression, morphological changes, and accumulation of lipid droplets. Reactive oxygen species (ROS) formation was significant at specific time points during differentiation, with NADPH oxidase (NOX)-2 playing a role. Mitochondrial ROS (mROS) were only detected in the late phase of differentiation, indicating potential mitochondrial dysfunction. These findings suggest a potential link between ROS, adipogenesis, and adipose tissue dysfunction in SW872 cells.

Summary: Simulating oxidative stress with gamma irradiation leads to shortened half-lives of neutrophils but pre-activates surviving cells to produce superoxide anions. Incomplete assembly of the NADPH oxidase complex after irradiation significantly enhances neutrophil reactivity.

Summary: This study evaluated the impact of Moroccan strains of L. major and L. tropica on PMNs. The results showed that L. tropica inhibited O-2(-) production, while L. major did not. Additionally, Leishmania soluble antigens from both species inhibited O-2(-) induction.

Summary: The study investigated the mechanism of podocyte apoptosis caused by COL4A3 mutations and found that NOX4 may induce podocyte apoptosis through the regulation of MMP-2 in patients with COL4A3 mutations. These findings provide new insights into the mechanism of ADAS.

Summary: This study investigates the role of ROS mediated by NADPH oxidase in the growth of F. solani. The results demonstrate that NCF2 gene plays a significant role in regulating the activity of NADPH oxidase and the expression of ROS metabolism enzyme genes, which affects colony growth in F. solani. Furthermore, exogenous H2O2 treatment also influences the growth and ROS metabolism of F. solani.

Summary: In this study, the function of NADPH oxidase in Chlorella pyrenoidosa was investigated. The results showed that NADPH oxidase actively participated in the production of intracellular ROS, and the ROS levels were higher under nitrogen and phosphorus-deficient conditions.

Summary: oxLDL is a biomarker and pathological factor in CVD, T2DM, obesity and other diseases, with a link to ER stress. The cellular response to ER stress involves a defensive mechanism known as UPR, which can switch to apoptosis under excessive stress to eliminate defective cells. ER stress is a major hallmark in metabolic syndromes and other diseases, with potential therapeutic interventions being explored.

Summary: Long-term treatment of schizophrenia with clozapine may lead to metabolic disorders, and this study found that clozapine can inhibit adipogenesis and reduce reactive oxygen species produced by NADPH oxidase. Clozapine also suppresses antioxidant responses and promotes mitochondrial superoxide formation, which may be associated with insulin resistance and metabolic syndrome. These cellular events may provide insights into the molecular mechanisms underlying the adverse metabolic effects of clozapine.

Summary: This study found that exposure to BPA exacerbates hypertension-induced pathological changes, including renal fibrosis, oxidative stress, elevated angiotensin-converting enzyme activity, dysfunction of antioxidant and tricarboxylic acid cycle enzymes, tissue lipid abnormalities, and expression of inflammatory factors. In addition, high levels of BPA have dose-dependent effects on kidney cells, including oxidative stress, mitochondrial dysfunction, and lipid peroxidation. Therefore, a precise investigation of BPA exposure in hypertensive populations is highly recommended during risk assessment.

Summary: This study investigated the antioxidant activity and toxicity of selenium-containing compounds in liver tissue. The results showed that these compounds have potential antioxidant effects, which can be attributed to their ability to scavenge free radicals and mimic enzyme activity. Additionally, one of the compounds exhibited low toxicity.
