Bifenthrin Under Scrutiny: Revisiting Toxicological Evidence Amid Regulatory Gaps

Journal of Applied Toxicology, EarlyView.
ABSTRACT Despite growing health concerns, bifenthrin (BF) remains widely used for controlling agricultural and residential pests. However, different perspectives on its toxicological profile and regulatory framework warrant a revisit and update on BF regulation towards a robust risk‐safety assessment.

P4‐ATPases as Phospholipid Flippases: From Membrane Dynamics to Human Disorders

Medicine Bulletin, EarlyView.
ABSTRACT P4‐ATPases (P4 subfamily of P‐type ATPases) flippase complex includes an α‐subunit responsible for catalysis and a supporting β‐subunit, which consumes energy by catalyzing the hydrolysis of ATP, thereby facilitating the translocation of aminophospholipids from the outer to the inner leaflet of cellular membranes to maintain the asymmetric ...

Role of Acid‐Sensing Ion Channels 1a in the Regulation of Obesity and the Gut Microbiota

Obesity, EarlyView.
ABSTRACT Objective Acid‐sensing ion channels are proton‐activated ion channels predominantly found in the nervous system. They are well known to affect metabolic and neurological health, yet their role in obesity and gut physiology remains unclear. This study investigates how systemic deletion of Asic1a influences obesity, metabolic, and gut‐based ...

Regulation of gene expression in ovarian cancer cells by luteinizing hormone receptor expression and activation

BMC Cancer, 2011
Background Since a substantial percentage of ovarian cancers express gonadotropin receptors and are responsive to the relatively high concentrations of pituitary gonadotropins during the postmenopausal years, it has been suggested that receptor ...
