Insights

This review highlights the role of Ether à-go-go (Eag) and Human ether à-go-go related gene (HERG) potassium channels in cancer. Inhibiting these channels shows potential for reducing tumor progression and offers new biomarker possibilities.

Area of Science:

  • Oncology
  • Molecular Biology
  • Channelopathies

Background:

  • Voltage-gated potassium channels are increasingly recognized for their involvement in cancer.
  • Specific channels, Ether à-go-go (Eag) and Human ether à-go-go related gene (HERG), are expressed across various cancer types.

Purpose of the Study:

  • To review the role of Eag and HERG potassium channels in cancer development.
  • To explore the therapeutic potential of targeting these channels for cancer treatment.
  • To assess the utility of Eag channels as potential tumor biomarkers.

Main Methods:

  • Literature review focusing on studies investigating Eag and HERG channels in cancer.
  • Analysis of in vitro and in vivo data on the effects of potassium channel inhibition on cancer cells.
  • Evaluation of expression patterns of Eag channels in normal versus cancerous tissues.

Main Results:

  • Eag and HERG channels are implicated in the cell cycle progression and proliferation of cancer cells.
  • Inhibition of Eag and HERG channels has demonstrated a reduction in cancer cell proliferation.
  • Potassium channel modulators are identified as potential inhibitors of tumor progression.
  • Eag channels exhibit restricted expression in normal tissues, suggesting potential as tumor biomarkers.

Conclusions:

  • Eag and HERG potassium channels play significant roles in cancer biology.
  • Targeting Eag and HERG channels represents a promising therapeutic strategy for cancer treatment.
  • Eag channels may serve as valuable novel biomarkers for early cancer detection and monitoring.

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.
Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Voltage-gated Ion Channels01:26

Voltage-gated Ion Channels

Voltage-gated ion channels are transmembrane proteins that open and close in response to changes in the membrane potential. They are present on the membranes of all electrically excitable cells such as neurons, heart, and muscle cells.
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several types of...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
