Antimicrobial cetylpyridinium chloride disrupts the mitochondrial electron transport chain as potently as cyanide, via cardiolipin interference at cytochrome C
CPC exhibits mitotoxicity as potent as cyanide, and the precise biochemical mechanism of action of this ubiquitous compound is determined to aid epidemiology, risk analysis, and predictive toxicology.
NLRX1 is established as an essential, CypD-independent regulator of mitochondrial permeability transition and provide brain-penetrant chemical tools to interrogate this biology.

Non-communicable diseases (NCDs) are increasing globally. Numerous studies have associated pesticide exposure with metabolic alterations in skeletal muscle and the development of related NCDs. Transfluthrin (TF), a volatile type-I pyrethroid insecticide, is widely used as a household mosquito repellent. Although effect...
The molecular basis by which BHT is converted from an innocuous antioxidant into a highly toxic quinone methide is elucidated and CYP2B10-catalyzed BHT bioactivation may provide a strategy for future targeted cell ablation technologies or environmental remediation of BHT.

Copper is a redox-active transition metal that is essential for the assembly and catalytic function of cytochrome c oxidase (Complex IV), the terminal enzyme of the mitochondrial electron transport chain and a principal site of physiological oxygen reduction. Elevated Complex IV activity and respiratory chain uncouplin...

Metabolic reprogramming is a hallmark of cancer cells, and stem-like populations often upregulate aldehyde dehydrogenases (ALDHs). Functional studies have established essential roles for individual ALDH isoforms in tumor initiation, progression, and metastasis; however, the mechanisms by which these enzymes promote mal...

Triclosan (TCS) is a broad-spectrum antimicrobial agent that has raised public health concerns due to its continuous environmental release and human exposure. Previous studies suggest that TCS may disrupt endocrine function. Nonetheless, the toxicological effects on the female reproductive system, notably on ovarian gr...
