Mitochondrial diseases are a large class of human hereditary diseases, accompanied by the dysfunction of mitochondria and the disruption of cellular energy synthesis, that affect various tissues and organ systems. Mitochondrial DNA mutation-caused disorders are difficult to study because of the insufficient number of clinical cases and the challenges of creating appropriate models. There are many cellular models of mitochondrial diseases, but their application has a number of limitations. The most proper and promising models of mitochondrial diseases are animal models, which, unfortunately, are quite rare and more difficult to develop. The challenges mainly arise from the structural features of mitochondria, which complicate the genetic editing of mitochondrial DNA. This review is devoted to discussing animal models of human mitochondrial diseases and recently developed approaches used to create them. Furthermore, this review discusses mitochondrial diseases and studies of metabolic disorders caused by the mitochondrial DNA mutations underlying these diseases.

The lack of knowledge about the mechanism of hyperoxia-induced intestinal injury has attracted considerable attention, due to the potential for this condition to cause neonatal complications. This study aimed to explore the relationship between hyperoxia-induced oxidative damage and ferroptosis in intestinal tissue and investigate the mechanism by which hyperoxia regulates inflammation through ferroptosis. The study systematically evaluated the effects of hyperoxia on oxidative stress, mitochondrial damage, ferroptosis, and inflammation of intestinal epithelial cells both in vitro and in vivo.

Outer mitochondrial membrane (OMM) proteins communicate with the cytosol and other organelles, including the endoplasmic reticulum. This communication is important in thermogenic adipocytes to increase the energy expenditure that controls body temperature and weight. However, the regulatory mechanisms of OMM protein insertion are poorly understood.

The opioid epidemic endangers not only public health but also social and economic welfare. Growing clinical evidence indicates that chronic use of prescription opioids may contribute to an elevated risk of ischemic stroke and negatively impact post-stroke recovery. In addition, NLRP3 inflammasome activation has been related to several cerebrovascular diseases, including ischemic stroke.

Complement factor H (CFH) common genetic variants have been associated with age-related macular degeneration (AMD). While most previous in vitro RPE studies focused on the common p.His402Tyr CFH variant, we characterized rare CFH variants that are highly penetrant for AMD using induced pluripotent stem-cell-derived retinal pigment epithelium (iPSC-RPE).

The widespread use of disinfectants, particularly during the coronavirus disease (COVID-19) pandemic, has significantly increased human exposure to biocides, raising concerns about their potential health risks, especially when inhaled. Benzalkonium chloride (BKC), a quaternary ammonium compound commonly used as a disinfectant and preservative, is a notable example because it is frequently used in household products and medical settings. Despite its broad usage, limited research has been conducted on the respiratory and systemic toxicities of BKC.
