Insecticide resistance seriously threatens efficient arthropod pest management. Arthropod glutathione S-transferases (GSTs) confer resistance via direct metabolism or sequestration of chemicals, but also indirectly by providing protection against oxidative stress induced by insecticide exposure. To date, GST activity has been associated with resistance to all main classes of insecticides. However, recent advances in genome and transcriptome sequencing, together with modern genetic, functional and biochemical techniques, facilitate the unraveling of specific GST-mediated resistance mechanisms. Recently, the role of a number of GSTs (BdGSTe2, BdGSTe4, AfGSTe2) has been validated by (reverse) genetic methods in vivo, while a number of GSTs (BmGSTu2, TuGSTd05, AfGSTe2) have now been shown to metabolize insecticides in vitro.

Glutathione S-transferases (GSTs) are promising pharmacological targets for developing antiparasitic agents against helminths, as they play a key role in detoxifying cytotoxic xenobiotics and managing oxidative stress. Inhibiting GST activity can compromise parasite viability. This study reports the successful identification of two selective inhibitors for the mu-class glutathione S-transferase of 25 kDa (Ts25GST) from , named and , using a computationally guided approach.

Asthma has been extensively studied in humans and animals, but the molecular mechanisms underlying asthma in Meishan pigs, a breed with distinct genetic and physiological characteristics, remain elusive. Understanding these mechanisms could provide insights into veterinary medicine and human asthma research. We investigated asthma pathogenesis in Meishan pigs through transcriptomic and metabolomic analyses of blood samples taken during autumn and winter.

Background: The resurgence of Anopheles funestus, a dominant vector of human malaria in western Kenya was partly attributed to insecticide resistance. However, evidence on the molecular basis of pyrethroid resistance in western Kenya is limited. Here, we reported metabolic resistance mechanisms and demonstrated that multiple non-coding Ribonucleic Acids (ncRNAs) could play a potential role in An.

Responses of biological characteristics and detoxification enzymes in the fall armyworm to methoxyfenozide stress.

Methoxyfenozide is an insecticide with a unique mode of action on the insect ecdysone receptor and has been registered for the control of insect pests all over the world. In the present work, Spodoptera frugiperda was exposed to sublethal and lethal concentrations of methoxyfenozide to determine its impact on specific biological traits, metabolic enzyme activity, and the expression of detoxification enzymes. The result showed that 72-h posttreatment with LC50 and LC70 of methoxyfenozide significantly reduced the fecundity (eggs/female) of the F0 generation compared to those of the control group.

Aedes albopictus (Ae. albopictus) is widely distributed and can transmit many infectious diseases, and insecticide-based interventions play an important role in vector control. However, increased insecticide resistance has become a severe public health problem, and the clarification of its detailed mechanism is a matter of urgence.
