Moderate exercise has been reported to combat several diseases, including cardiovascular diseases and depressants. However, many patients do not have ability to undergo exercise therapy due to aging and severity of the symptoms. Therefore development of new drugs that can imitate exercise therapy is desired and actually studied worldwide. The heart is one of the physical load-responsive target organs such as skeletal muscles and vascular smooth muscles. The heart can adapt from environmental stress by changing its structure and morphology (i.e., remodeling). Physiological remodeling, caused by exercise or pregnancy, can be defined by compensative and reversible changes to the heart, whereas pathological remodeling can be defined by irreversible changes of the heart, through aberrant calcium ion (Ca2 ＋ ) signaling as well as production of reactive oxygen species (ROS). However, crosstalk between Ca2 ＋ and ROS remains obscure. In this review we will introduce our recent findings on the functional crosstalk between transient receptor potential canonical (TRPC) 3 and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (Nox) 2 as a novel molecular target to mimic exercise therapy.
