Cytoskeletal regulation of TRPC channels in the cardiorenal system.
Transient receptor potential canonical (TRPC) channels have been implicated in several aspects of cardiorenal physiology including regulation of blood pressure, vasoreactivity, vascular remodeling, and glomerular filtration. Gain and loss of function studies also support the role of TRPC channels in adverse remodeling associated with cardiac hypertrophy and heart failure. This review discusses TRP channels in the cardiovascular and glomerular filtration systems and their role in disease pathogenesis. We describe the regulation of gating of TRPC channels in the cardiorenal system as well as the influence on activation of these channels by the underlying cytoskeleton and scaffolding proteins. We then focus on the role of TRP channels in the pathogenesis of adverse cardiac remodeling and as potential therapeutic targets in the treatment of heart failure.
