17. Activation of TRPM2 channels, however, caused intracellular release of not only Ca(2+) but also of Zn(2+) Intriguingly, elevation of intracellular Zn(2+) faithfully reproduced all of the effects of H2O2, whereas Ca(2+) showed opposite effects. Interestingly, H2O2 caused increased trafficking of Zn(2+)-enriched lysosomes to the leading edge of migrating cells, presumably to impart polarisation of Zn(2+) location.

18. neutrophils sense reactive oxygen species via the TRPM2 channel to arrest migration at their target site.

19. The inhibitory function of oxidant sensing by TRPM2 requires the oxidation of Cys549, which then induces TRMP2 binding to formyl peptide receptor 1 (FPR1) and subsequent FPR1 internalization and signaling inhibition

20. findings demonstrate the important function of TRPM2 in modulation of cell survival through mitochondrial ROS, and the potential of targeted inhibition of TRPM2 as a therapeutic approach to reduce cellular bioenergetics, tumor growth, and enhance susceptibility to chemotherapeutic agents.

Mouse (Murine) Transient Receptor Potential Cation Channel, Subfamily M, Member 2 (TRPM2) interaction partners

1. this study provides insight into the mechanism determining tumor cell susceptibility to neutrophil cytotoxicity. This mechanism depends on the expression of the H2O2-responsive Ca2+ channel TRPM2. TRPM2 expression is upregulated in cancerous tissues, making tumor cells more susceptible to neutrophil cytotoxicity.

2. TRPM2 silencing inhibits also lung cancer cells invasion ability and alters EMT processes and TRPM2 downregulation causes an increase in the intracellular levels of reactive oxygen (ROS) and nitrogen (RNS) species, which in turn causes DNA damage and JNK activation leading to G2/M arrest, and an ultimate cell death.
