Phytic acid alleviates ochratoxin A-induced renal damage in chicks by modulating ferroptosis and the structure of the intestinal microbiota.

Phytic acid (PA) is a natural antioxidant with various biological activities, providing protective effects in multiple animals. Ochratoxin A (OTA) is a mold toxin commonly found in feed, which induces multi-organ damage, with kidney being the target organ of its toxicity. This study investigates the protective effects of PA on OTA-induced renal damage and its potential mechanisms in chicks.

Cadmium aggravates liver injury by activating ferroptosis and neutrophil extracellular traps formation in Nile tilapia (Oreochromis niloticus).

Cadmium (Cd) is a pervasive environmental contaminant and a significant risk factor for liver injury. The present study was undertaken to evaluate the involvement of ferroptosis and neutrophil extracellular traps (NETs) in Cd-induced liver injury in Nile tilapia (Oreochromis niloticus), and to explore its underlying mechanism. Cd-induced liver injury was associated with increased total iron, malondialdehyde (MDA), and Acyl-CoA synthetase long-chain family member 4 (ACSL4), together with reduced levels of glutathione, glutathione peroxidase-4a (Gpx4a), and solute carrier family 7 member 11 (SLC7A11), which are all hallmarks of ferroptosis.

β-Carotene Protects Mice against Lipopolysaccharide and D-Galactosamine Induced Acute Liver Injury via Regulation of NF-κB, MAPK, and Nrf2 Signaling.

Acute liver injury (ALI), posing a serious threaten to our life, has emerged as a public health issue around the world. β-carotene has plenty of pharmacologic effects, such as anti-inflammatory, antioxidant, and antitumor activities. In this study, we focused on studying the protective role and potential molecular mechanisms of β-carotene against D-galactosamine (D-GalN) and lipopolysaccharide (LPS) induced ALI.

Exposure to ZnO nanoparticles induced blood-milk barrier dysfunction by disrupting tight junctions and cell injury.

Zinc oxide nanoparticles (ZnO-NPs) are one of the most widely used nanomaterials with excellent chemical and biological properties. However, their widespread application has led to increased risk to the natural environment and public health. A growing number of studies have shown that ZnO-NPs deposited in target organs interact with internal barriers to trigger injurious responses.

Quercetin Alleviates Deoxynivalenol-Induced Intestinal Damage by Suppressing Inflammation and Ferroptosis in Mice.

Deoxynivalenol (DON), one of the most prevalent mycotoxins found in food and feed, can cause gastrointestinal inflammation and systemic immunosuppression, presenting a serious hazard to human and animal health. Quercetin (QUE) is a plant polyphenol with anti-inflammatory and antioxidant properties. In this research, we investigated the potential function of QUE as a treatment for DON-induced intestinal damage.

Saxitoxin induces the release of human neutrophil extracellular traps.

Saxitoxin (STX) is a potent shellfish toxin found in freshwater and marine ecosystems which threatens human health by contaminating drinking water and shellfish. The formation of neutrophil extracellular traps (NETs) is a defense mechanism employed by polymorphonuclear leukocytes (PMNs) to destroy invading pathogens, and also plays a critical role in the pathogenesis of various diseases. In this study, we aimed to investigate the role of STX on human NET formation.
