Possible involvement of transient receptor potential channels in electrophile-induced insulin secretion from RINm5F cells.

abstract：:The N-methyl-D-aspartate (NMDA) receptor plays a key role in learning and memory. Our recent studies have shown that nobiletin from citrus peels activates the cAMP response element-binding protein (CREB) signaling pathway and ameliorates NMDA receptor antagonist-induced learning impairment by activating extracellular ...
