Functional analysis of quorum sensing-mediated pathogenicity in Burkholderia contaminans SK875 using transposon mutagenesis.

Burkholderia contaminans SK875, a member of Burkholderia cepacia complex (Bcc), are known to cause lung infections in cystic fibrosis patients.

Reproductive toxicity and transgenerational effects of co-exposure to polystyrene microplastics and arsenic in zebrafish.

Microplastics (MPs) are ubiquitous environmental pollutants that have garnered significant attention due to their small particle size, resistance to degradation and large specific surface area, which makes it easy to adsorb various pollutants, particularly heavy metals. Arsenic (As), a common metal poisons, poses significant risks due to its widespread industrial use. When MPs and As co-exist in the environment, they can exert combined toxic effects on organisms, affecting various systems, including the nervous system.

TET1 participates in oxaliplatin-induced neuropathic pain by regulating microRNA-30b/Nav1.6.

Chemotherapy-induced neuropathic pain poses significant clinical challenges and severely impacts patient quality of life. Sodium ion channels are crucial in regulating neuronal excitability and pain. Our research indicates that the microRNA-30b (miR-30b) in rat dorsal root ganglia (DRG) contributes to chemotherapy-induced neuropathic pain by regulating the Nav1.

Predicting metal-binding proteins and structures through integration of evolutionary-scale and physics-based modeling.

Metals are essential elements in all living organisms, binding to approximately 50% of proteins. They serve to stabilize proteins, catalyze reactions, regulate activities, and fulfill various physiological and pathological functions. While there have been many advancements in determining the structures of protein-metal complexes, numerous metal-binding proteins still need to be identified through computational methods and validated through experiments.
