Abstract

Insights

Targeting connexins (Cxs) and gap junctional intercellular communications (GJICs) offers novel cancer therapies. Restoring Cxs expression and leveraging their functions show promise for eliminating cancer cells and enhancing treatment efficacy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Biology

Background:

  • Connexins (Cxs) and gap junctional intercellular communications (GJICs) are implicated in cancer progression.
  • Targeting Cxs presents a novel strategy for cancer treatment, potentially inhibiting tumor growth or sensitizing cells to therapy.

Purpose of the Study:

  • To review therapeutic strategies involving connexins and gap junctions in cancer treatment.
  • To explore the role of Cxs in gene therapy, chemosensitization, apoptosis, and microenvironment interactions.

Main Methods:

  • Literature review focusing on therapeutic aspects of Cxs in cancer.
  • Analysis of strategies to restore connexin expression (transcriptional and post-transcriptional).

Main Results:

  • Connexins facilitate cancer cell elimination through bystander effects, chemosensitization, and modulation of apoptosis.
  • Strategies to restore connexin expression and leverage their functions are being explored.
  • The potential and limitations of these connexin-based therapeutic approaches are discussed.

Conclusions:

  • Connexins exhibit diverse roles in cancer, acting individually, in complexes, or interacting with other proteins.
  • Selective manipulation of Cxs expression remains challenging due to unresolved regulatory mechanisms.
  • Further research into connexin regulation and function is crucial to fully realize their therapeutic potential.

Gap Junctions01:37

Gap Junctions

Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...
Gap Junctions01:27

Gap Junctions

The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...

Overview of Cell-Cell Junctions

The complex three-dimensional arrangement of cells in any multicellular organism is defined and maintained by interactions of cells with each other and the extracellular matrix. Cell-cell junctions are specialized structures where the multi-protein complexes on one cell interact with the multi-protein complexes on another  cell. These cell junctions are classified  into three main types based on their function — occluding, anchoring, and gap junctions.

Contact-dependent Signaling01:19

Contact-dependent Signaling

Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

Targeted Cancer Therapies02:57

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...
