Overview of Gene Research
Trpm2, also known as transient receptor potential melastatin 2, is an oxidant-activated non-selective cation channel [2]. It functions as an endogenous redox sensor, mediating oxidative stress/ROS-induced Ca(2+) entry and subsequent Ca(2+)-dependent cellular reactions like endothelial hyperpermeability and apoptosis [2]. It is widely expressed in mammalian tissues, including the vascular endothelium [2]. Oxidative stress stimulates intracellular ADP-ribose formation which opens TRPM2 channels [2]. 2'-Deoxyadenosine 5'-diphosphoribose is an endogenous TRPM2 superagonist, which may act as a cell signaling molecule [3].
In the context of acute myocardial infarction (AMI), knockout of Trpm2 protected against myocardial injury and led to upregulation of clusterin (CLU) [1]. In H9C2 cells under hypoxic conditions, silencing of Trpm2 increased cell viability and decreased its own expression [1]. This indicates that Trpm2 may play a role in myocardial injury during AMI, and its knockout can have a protective effect [1].
In conclusion, Trpm2 is a crucial non-selective cation channel involved in redox-mediated Ca(2+) signaling. Its knockout in mouse models reveals its role in myocardial injury during AMI, suggesting that understanding Trpm2 function can potentially lead to new treatment strategies for AMI.
