The purpose of this research was to examine the impact of glycine on intestinal injury caused by oxidative stress in piglets. A 2 × 2 factorial experiment with diets (basic diet vs. 1% glycine diet) and oxidative stress (saline vs. diquat) was conducted on 32 weanling piglets. On day 21, all piglets received an injection of either saline or diquat. After 7 days, all pigs were slaughtered and intestinal samples were collected. Dietary glycine supplementation improved intestinal mucosal morphology, increased the activities of disaccharidases and enhanced intestinal mucosal antioxidant capacity, while regulating the expression of ferroptosis mediators in the piglets under oxidative stress. These findings suggested that dietary glycine supplementation improved the morphology and function of the intestinal mucosa, which was involved in regulating antioxidant capacity and ferroptosis.

Activation of bone morphogenetic protein (BMP) 4 signaling promotes the survival of retinal ganglion cell (RGC) after acute injury. In this study, we investigated the role of the BMP4 signaling pathway in regulating the degeneration of retinal ganglion cells (RGCs) in a mouse glaucoma model and its potential application in retinal stem cell. Our results demonstrate that BMP4-GPX4 not only reduces oxidative stress and iron accumulation but also promotes neuroprotective factors that support the survival of transplanted RSCs into the host retina.

Purpose: In vitro, oocyte development is susceptible to oxidative stress, which leads to endoplasmic reticulum (ER) stress. This study investigated whether the antioxidant melatonin attenuates ER stress and maintains oocyte-cumulus cell communication during the in vitro growth (IVG) of bovine oocytes.

Methods: Oocyte-granulosa cell complexes (OGCs) were harvested from slaughterhouse-derived ovaries and grown in vitro for 5 d at 38.

Introduction: Heavy metal soil pollution is a global issue that can be efficiently tackled through the process of phytoremediation. The use of rapeseed in the phytoremediation of heavy metal-contaminated agricultural land shows great potential. Nevertheless, its ability to tolerate heavy metal stress at the molecular level remains unclear.

Drought stress inhibits Bunge () seedling growth and yield. Here, we studied the effects of drought stress on the different parts of seedlings through physiological, transcriptomic, and metabolomics analyses, and identified key genes and metabolites related to drought tolerance. Physiological analysis showed that drought stress increased the accumulation of hydrogen peroxide (HO), enhanced the activity of peroxidase (POD), decreased the activity of catalase (CAT) and the contents of chlorophyll b and total chlorophyll, reduced the degree of photosynthesis, enhanced oxidative damage in seedlings, and inhibited the growth of plants.
