Summary: This study investigated the toxic effects of Cu-NPs and Cu2+ on Takifugu fasciatus, showing organ injuries, abnormal enzyme activities, and significant changes in the expression of TfCRT gene. Both Cu-NPs and Cu2+ had negative impacts on the health of T. fasciatus, with Cu-NPs exhibiting toxic effects similar to dissolved Cu.

Summary: This study reports the synthesis, characterisation, and anti-breast cancer stem cell (CSC) properties of a series of copper(ii)-terpyridine complexes containing aryl sulfonamide groups. One of these complexes, with p-toluene sulfonamide, is more potent than established anti-CSC drug salinomycin and anticancer drug cisplatin. The complexes enter breast CSCs, generate intracellular reactive oxygen species (ROS), induce endoplasmic reticulum stress, and trigger apoptosis.

Summary: Nonalcoholic fatty liver disease (NAFLD) can cause serious liver damage, and early diagnosis and treatment of NAFLD can greatly improve treatment success rates. A new near-infrared (NIR) fluorescence imaging probe, Er-V, successfully monitored increased viscosity in the livers of mice with NAFLD, offering a new approach for early detection and diagnosis of NAFLD.

Summary: This study established a NAFLD model using HFD-fed rats and FFA-stimulated THP-1 cells to examine the role of hesperidin in ERS-induced inflammation in NAFLD pathogenesis. The results showed that hesperidin reduced hepatic steatosis and inflammatory response, as well as the expression of ERS-related biomarkers.

Summary: This study found that fenofibrate can alleviate ER stress and improve the pathology of NAFLD by regulating the expression of let-7 miRNA and SERCA2b. This provides new insights into the specific mechanism of fenofibrate in treating NAFLD and improving lipid metabolism disorders.

Summary: The study identified FOXA3 as a key bridging molecule connecting ER stress and NAFLD progression, with its deficiency alleviating fatty liver. Increased levels of FOXA3 were found in the livers of obese mice and patients with NAFLD, suggesting FOXA3 as a potential therapeutic target for fatty liver disease.

Summary: Copper (Cu) at high levels can cause harm to the host physiology, specifically resulting in nephrotoxicity, although the exact mechanism remains unclear. This study explored the relationship between mitochondria-associated ER membranes (MAM) and Cu-induced kidney mitochondrial dysfunction and ER stress. The findings revealed that excessive Cu disrupted MAM integrity, leading to MAM dysfunction, mitochondrial dysfunction, and ER stress, contributing to Cu-induced nephrotoxicity.

Summary: This study investigates the role of IKK beta signaling in obesity. The results show that the deletion of IKK beta in the liver and leukocytes is not tolerated in obese mice exposed to TLR3 agonists. However, selective hepatic IKK beta ablation improves fatty liver and insulin sensitivity.

Summary: High concentrations of copper pose a threat to aquatic animals, but the response mechanisms of crustaceans to Cu2+ exposure are not well understood. This study investigated the physiological and molecular changes in Chinese mitten crabs after Cu2+ exposure. The results showed that Cu2+ exposure decreased antioxidative capacity and promoted lipid peroxidation in different tissues. It also induced apoptosis and autophagy, and triggered an immune response. The toxicity of Cu2+ may be associated with the activation of ERK, AMPK, and TLR2-MyD88-NF-kappa B pathways.

Summary: This study demonstrated that an overdose of copper can induce mitophagy and ER stress-mediated apoptosis in the chicken cerebrum. These findings revealed an important potential connection between copper toxicity and cerebrum damage, which provided a new insight into copper neurotoxicity.

Summary: Icariin (ICA) can attenuate non-alcoholic fatty liver disease (NAFLD) by reducing liver lipid deposition and improving insulin sensitivity, glucose tolerance, etc. The main metabolite of ICA, icaritin (ICT), inhibits hepatic lipid accumulation and lipogenesis by reducing endoplasmic reticulum (ER) stress.

Summary: This study investigated the mechanism of copper toxicity in the cardiomyocytes of large mammal pigs. The results showed that excessive copper intake caused oxidative damage, activated antioxidant pathways and endoplasmic reticulum stress, disrupted mitochondrial balance, and induced cell apoptosis.
