2. Nishida M, Ohba M, Nakaya M & Kurose H., Heart Failure: Symptoms, Causes and Treatment Options, NOVA Publishers (New York), 2011.03, Structural remodeling of the heart, including myocardial hypertrophy and fibrosis, is a key determinant for the clinical outcome of heart failure. A variety of evidence indicates the importance of neurohumoral factors, such as endothelin-1, angiotensin II, and norepinephrine for the initial phase of the development of cardiac remodeling. These agonists stimulate seven transmembrane spanning receptors that are coupled to heterotrimeric GTP-binding proteins (G proteins) of the Gi, Gq and G12 subfamilies. The pathophysiological roles of each G protein-mediated signaling have been revealed by studies using transgenic and knockout mice. Using specific pharmacological tools to assess the involvement of G protein signaling pathways, we have found that diacylglycerol-activated transient receptor potential canonical (TRPC) channels (TRPC3 and TRPC6), one of the downstream effectors regulated by Gαq, work as a key mediator in the development of cardiac hypertrophy. In contrast, we also revealed that activation of Gα12 family proteins in cardiomyocytes mediates pressure overload-induced cardiac fibrosis. Stimulation of purinergic P2Y6 receptors by extracellular nucleotides released by mechanical stretch is a trigger of Gα12-mediated fibrotic responses of the heart. Although cardiac fibrosis is believed to accompany with Gαq-mediated pathological hypertrophy that eventually results in heart failure, our results clearly show that cardiac fibrosis and hypertrophy are independent processes. These findings will provide a new insight into the molecular mechanisms underlying pathogenesis of heart failure..

In our investigation of how Ang II signals are converted by the AT1R from physiological to pathological outputs, we found that the purinergic P2Y6 receptor (P2Y6R), an inflammation-inducible G protein (heterotrimeric guanine nucleotide–binding protein)–coupled receptor (GPCR), promoted Ang II–induced hypertension in mice. In mice, deletion of P2Y6R attenuated Ang II–induced increase in blood pressure, vascular remodeling, oxidative stress, and endothelial dysfunction. AT1R and P2Y6R formed stable heterodimers, which enhanced G protein–dependent vascular hypertrophy but reduced β-arrestin–dependent AT1R internalization. Pharmacological disruption of AT1R-P2Y6R heterodimers by the P2Y6R antagonist MRS2578 suppressed Ang II–induced hypertension in mice. Furthermore, P2Y6R abundance increased with age in vascular smooth muscle cells. The increased abundance of P2Y6R converted AT1R-stimulated signaling in vascular smooth muscle cells from β-arrestin–dependent proliferation to G protein–dependent hypertrophy. These results suggest that increased formation of AT1R-P2Y6R heterodimers with age may increase the likelihood of hypertension induced by Ang II..
