Insights

Transient receptor potential melastatin (TRPM) channels are implicated as oncogenes in various cancers. This review details their roles in cancer progression and potential therapeutic targets.

Area of Science:

  • Ion channel biology
  • Molecular oncology
  • Cancer research

Background:

  • Transient receptor potential (TRP) proteins are crucial ion channels regulating cellular responses.
  • The TRPM (melastatin) subfamily comprises eight members controlling cation fluxes (K+, Na+, Ca2+, Mg2+).
  • Emerging evidence links TRPM channels and their associated noncoding RNAs to oncogenesis.

Purpose of the Study:

  • To review recent findings on TRPM channels in human malignancies.
  • To elucidate the functions and mechanisms of TRPM channels in cancer.
  • To summarize physiological roles and pharmacological inhibitors of TRPM channels.

Main Methods:

  • Literature review of recent studies on TRPM channels in cancer.
  • Analysis of TRPM channel functions, mechanisms, and signaling pathways in malignancies.
  • Compilation of data on TRPM channel physiological roles and therapeutic agents.

Main Results:

  • TRPM channels are implicated as oncogenes in cancer cell growth, proliferation, autophagy, invasion, and epithelial-mesenchymal transition.
  • Dysregulation of TRPM channels is associated with poor clinical outcomes in cancer patients.
  • TRPM channels play significant roles in various types of cancer.

Conclusions:

  • TRPM channels are critical regulators in cancer development and progression.
  • Understanding TRPM channel functions offers potential for novel cancer therapies.

Ion Channels

The movement of ions like sodium, potassium, and calcium into and out of the cell is essential to maintain the electrochemical gradient in living cells. The ion channels—a class of membrane transport proteins—help maintain this ionic gradient for the smooth functioning of physiological activities such as maintaining cell size and volume, conducting nerve impulses, and gas and nutrient exchange.
Ion channels are specialized integral membrane proteins on the plasma membrane that allow...

The Role of Ion Channels in Neuronal Computation

A postsynaptic neuron usually receives numerous impulses from several other presynaptic neurons. The axon hillock of the postsynaptic neuron integrates all these signals and determines the likelihood of firing an action potential.
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....

Non-gated Ion Channels01:24

Non-gated Ion Channels

Ion channels are specialized proteins on the plasma membrane that allow charged ions to pass down their electrochemical gradient. Their main function is to maintain the membrane potential which is critical for cell viability. These channels are either gated or non-gated and can transport more than a thousand ions within milliseconds for the cellular event to occur.
Compared to the gated ion channels, the non-gated channels, also known as leakage or passive channels, have no gating mechanism....

Mechanically-gated Ion Channels01:12

Mechanically-gated Ion Channels

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...

G-Protein Gated Ion Channels

GPCRs are primarily responsible for our sense of smell, taste, and vision.  The binding of a sensory stimulus activates GPCR to stimulate effector proteins, many of which are ion channels in the sensory organs. GPCRs modulate the opening and closing of the target ion channels either directly by binding them, or by releasing second messengers that activate these channels. As ions move across the membrane, the membrane potential is altered, which induces an appropriate response.
