TRPC6

TRPC6 is a member of the canonical transient receptor potential (TRPC) subfamily of proteins that are expressed in various tissues and play a role in receptor-operated Ca2+ channels. TRPC6 is encoded by the TRPC6 gene in humans.

Function

TRPC6 is a non-selective cation channel that is activated in response to signals from G-protein coupled receptors. It is involved in various physiological processes, including the regulation of systemic blood pressure, pulmonary artery smooth muscle cell proliferation, and glomerular filtration rate.

Clinical significance

Mutations in the TRPC6 gene have been associated with several diseases, including focal segmental glomerulosclerosis (FSGS) and pulmonary arterial hypertension (PAH). In FSGS, mutations in TRPC6 lead to an increase in calcium influx, which results in podocyte injury and proteinuria. In PAH, TRPC6 overexpression contributes to the proliferation of pulmonary artery smooth muscle cells, leading to vascular remodeling and increased pulmonary vascular resistance.

Research

Research on TRPC6 has focused on its role in disease pathogenesis and potential as a therapeutic target. Studies have shown that inhibiting TRPC6 activity can reduce proteinuria in animal models of FSGS, suggesting that TRPC6 inhibitors could be a potential treatment for this disease. Similarly, TRPC6 inhibitors have been shown to reduce pulmonary artery smooth muscle cell proliferation in PAH, suggesting a potential therapeutic role in this condition as well.
