Summary
Transient receptor potential melastatin 2 (TRPM2) channels sense oxidative stress. This review highlights TRPM2
Area of Science:
- Molecular biology
- Cell physiology
- Ion channel function
Background:
- The Transient Receptor Potential (TRP) superfamily comprises seven subfamilies of cation channels.
- TRPM2, a member of the TRPM subfamily, forms a Ca(2+)-permeable cation channel.
- TRPM2 is expressed in various cell types, regulating diverse cellular functions.
Purpose of the Study:
- To review recent advancements concerning the TRPM2 channel.
- To explore TRPM2's role as a sensor for oxidative stress.
- To discuss TRPM2's potential as a therapeutic target for oxidative stress-related diseases.
Main Methods:
- Literature review of recent scientific publications.
- Analysis of studies on TRPM2 channel activation and function.
- Examination of evidence linking TRPM2 to oxidative stress and disease pathology.
Main Results:
- TRPM2 channels are activated by ADP-ribose (ADPR), Ca(2+), and reactive oxygen species (ROS) like H2O2.
- TRPM2 functions as a cellular sensor for oxidative stress, mediating calcium influx.
- TRPM2 activity contributes to pathological processes in numerous cell types.
Conclusions:
- TRPM2 plays a critical role in cellular responses to oxidative stress.
- Dysregulation of TRPM2 contributes to various diseases.
- TRPM2 represents a promising therapeutic target for treating oxidative stress-related conditions.

01:43Thermosensation
29.7K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

01:31Regulation of the Unfolded Protein Response
2.2K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

01:12Mechanically-gated Ion Channels
6.6K
Mechanically-gated ion channels are proteins found in eukaryotic and prokaryotic cell membranes that open in response to mechanical stress. Tension, compression, swelling, and shear stress can alter the conformation of the protein, opening a transmembrane channel that allows the passage of ions for signal transmission. In eukaryotes, mechanically-gated channels are distributed in several regions like the neurons, lungs, skin, bladder, and heart, where they play critical roles in numerous...

01:46Electron Transport Chain: Complex I and II
11.9K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.

2.5K
Most organisms use photoreceptors to sense and respond to light. Examples of photoreceptors include bacteriorhodopsins and bacteriophytochromes in some bacteria, phytochromes in plants, and rhodopsins in the photoreceptor cells of the vertebral retina. The light-sensitive property of these receptors is because of the bound chromophores, such as bilin in the phytochromes and retinal in the rhodopsins.
Rhodopsins belong to the family of cell surface proteins called G-protein coupled receptors,...

Bacteria have global regulatory systems that control several types of stress mechanisms. These include Pho regulon and the heat shock response, which are essential systems for environmental adaptation, such as nutrient limitation and proteotoxic stress. The Pho regulon and the heat shock response exemplify bacterial resilience, enabling rapid adaptation to fluctuating environmental conditions.Pho RegulonBacteria require phosphorus for essential cellular processes, including nucleic acid...
