TRPC Channels in Cardiac Plasticity

TRPC channels as effectors of cardiac hypertrophy.

Transient receptor potential (TRP) channels of multiple subclasses are expressed in the heart, although their functions are only now beginning to emerge, especially for the TRPC subclass that appears to regulate the cardiac hypertrophic response. Although TRP channels permeate many different cations, they are most often ascribed a specific biological function because of Ca(2+) influx, either fo...

TRPC channels are necessary mediators of pathologic cardiac hypertrophy.

Pathologic hypertrophy of the heart is regulated through membrane-bound receptors and intracellular signaling pathways that function, in part, by altering Ca(2+) handling and Ca(2+)-dependent signaling effectors. Transient receptor potential canonical (TRPC) channels are important mediators of Ca(2+)-dependent signal transduction that can sense stretch or activation of membrane-bound receptors....

TRPC Channels in Sensory Systems

The mammalian TRPC cation channels.

Transient Receptor Potential-Canonical (TRPC) channels are mammalian homologs of Transient Receptor Potential (TRP), a Ca(2+)-permeable channel involved in the phospholipase C-regulated photoreceptor activation mechanism in Drosophila. The seven mammalian TRPCs constitute a family of channels which have been proposed to function as store-operated as well as second messenger-operated channels in...

TRPC channels in smooth muscle cells.

Transient receptor potential canonical (TRPC) proteins constitute a family of seven (TRPC1-7) nonselective cation channels within the wider TRP superfamily. TRPC1, TRPC3, TRPC4, TRPC5 and TRPC6 channels are expressed in vascular smooth muscle cells from human vessels of all calibers and in smooth muscle from organs such as the uterus and the gastrointestinal tract. TRPC channels have recently e...
