Zinc is an essential micronutrient that serves as a cofactor in a wide variety of enzymes, including Cu-Zn Superoxide Dismutase 1 (Sod1). We have discovered in Schizosaccharomyces pombe that Sod1 mRNA and protein levels are regulated in response to cellular zinc availability. We demonstrate that lower levels of Sod1 mRNA and protein accumulate under low zinc conditions, and that this regulation does not require the sod1 promoter or known factors that regulate transcription of sod1 in response to zinc and other environmental stresses.

Intrauterine growth restriction (IUGR) induced by utero-placental insufficiency (UPI) results in delayed neural development and impaired brain growth. This study investigates the effects of Naringin (Nar) on memory, learning, cholinergic activity, oxidative stress markers, hippocampal CREB/BDNF signal pathway and cell damage in offspring of rats exposed to UPI. Twenty pregnant Wistar rats were randomly assigned to four groups: control, sham surgery, UPI + NS (UPI + normal saline as a vehicle), and UPI + Nar (UPI + Nar at 100 mg/kg/day).

The aim of this study was to decipher the reprogramming of protective machineries and sulfur metabolism, as responses to time-dependent effect of fluoride stress for 10 and 20days in two indica rice (Oryza sativa ) varieties. Unregulated accumulation of fluoride via chloride channels (CLC1 and CLC2) in 10-day-old (cv. Khitish) and 20-day-old (cv.

Using autologous orthotopic liver transplantation (AOLT) model in rats, the effect of lipid reactive oxygen species (L-ROS) inhibitor Ferrostain-1 on ferroptosis signal pathway was observed to determine whether ferroptosis occurred in rat liver injury after cold ischemia-reperfusion (I/R). Thirty-two healthy adult SPF male SD rats, 8 ~ 10 weeks old, weight 240 ~ 260 g, were divided into four groups by the method of random number table (n = 8): sham group, I/R group, I/R + Fer-1 group, I/R + DFO group. In the I/R + Fer-1 group, ferristatin-1(5 mg /kg) was intraperitoneally injected 30 min before surgery; in the I/R + DFO group, DFO 100 mg/kg was injected intraperitoneally 1 h before operation and 12 h after operation.

Reactive oxygen species (ROS) generated by oxidative stress have emerged as critical factors in the pathophysiology of malignancies. This study investigated the antioxidant and anticancer properties of zinc (Zn), selenium (Se), and silver (Ag) nanoparticles (NPs) against the A2780 human ovarian cancer cell line. Here, the bioinformatics approach was used to determine the top differentially expressed genes associated with oxidative stress.
