Blockade of Transient Receptor Potential Vanilloid 4 Enhances Antioxidation after Myocardial Ischemia/Reperfusion

Transient Receptor Potential Vanilloid

Transient Receptor Potential Vanilloid 1

Background and structure Transient receptor potential vanilloid receptor 1 (TRPV1) is one of 6 members of the subfamily of vanilloid receptors that belongs to the family of transient receptor potential (TRP) channels. TRP channels are an intrinsic part of the mammalian sensory system responding to a broad range of stimuli such as temperature, touch, pain, osmolarity, pheromones, and taste (8). ...

Transient Receptor Potential Vanilloid 2 Regulates Myocardial Response to Exercise

The myocardial response to exercise is an adaptive mechanism that permits the heart to maintain cardiac output via improved cardiac function and development of hypertrophy. There are many overlapping mechanisms via which this occurs with calcium handling being a crucial component of this process. Our laboratory has previously found that the stretch sensitive TRPV2 channels are active regulators...

Blockage of transient receptor potential vanilloid 4 alleviates myocardial ischemia/reperfusion injury in mice

Transient receptor potential vanilloid 4 (TRPV4) is a Ca2+-permeable nonselective cation channel and can be activated during ischemia/reperfusion (I/R). This study tested whether blockade of TRPV4 can alleviate myocardial I/R injury in mice. TRPV4 expression began to increase at 1 h, reached statistically at 4 h, and peaked at 24-72 h. Treatment with the selective TRPV4 antagonist HC-067047 or ...

Transient receptor potential vanilloid gene deletion exacerbates inflammation and atypical cardiac remodeling after myocardial infarction.

The transient receptor potential vanilloid (TRPV1) channels expressed in sensory afferent fibers innervating the heart may be activated by protons or endovanilloids released during myocardial ischemia (MI), leading to angina. Although our previous in vitro data indicate that TRPV1 activation may preserve cardiac function after ischemia-reperfusion injury, the underlying mechanisms are largely u...
