TRPC3 and pulmonary arterial hypertension: Given the resistance to RV dilation observed in transient receptor potential canonical 3(Trpc3)−/− mice during a pulmonary hypertension model induced by phenylephrine (PE), we hypothesized that TRPC3 also plays a role in chronic intermittent hypoxia (CIH) conditions, which lead to RV dilation and dysfunction.
