Insights

Targeting the E-cadherin/catenin complex offers a promising strategy for anti-cancer invasion therapy. This complex

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Biology

Background:

  • Cancer invasion is a significant obstacle in effective cancer therapy.
  • The balance between molecular invasion-promoter and invasion-suppressor complexes dictates cancer cell invasiveness.
  • The E-cadherin/catenin complex acts as a key invasion-suppressor complex with multifactorial regulation.

Purpose of the Study:

  • To explore the E-cadherin/catenin complex as a therapeutic target for anti-invasion strategies.
  • To understand the mechanisms regulating the E-cadherin/catenin complex's function in cancer invasion.

Main Methods:

  • Review of molecular mechanisms regulating E-cadherin/catenin complex stability and function.
  • Analysis of genetic and posttranslational modifications affecting E-cadherin/catenin complex activity.
  • Investigation of extracellular and intracellular interactions involving the E-cadherin/catenin complex.

Main Results:

  • E-cadherin/catenin complex downregulation can be irreversible (gene mutations) or reversible (beta-catenin phosphorylation).
  • Tyrosine phosphorylation of beta-catenin and transmembrane receptor signaling impact complex function.
  • Extracellular homophilic E-cadherin interaction via the HAV sequence is crucial for cell adhesion.
  • Insulin-like growth factor-I and tamoxifen have demonstrated potential to upregulate the complex and inhibit invasion in vitro.

Conclusions:

  • The E-cadherin/catenin complex is a viable and attractive target for developing novel anti-invasion therapies.
  • Targeting the reversible regulatory mechanisms of the E-cadherin/catenin complex holds therapeutic potential.
  • Further research into modulating this complex could lead to effective anti-invasive cancer treatments.

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However, invadopodia can...
Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
Catenins01:23

Catenins

Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
Catenins in Cell Junctions
Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the adherens...
Adherens Junctions01:24

Adherens Junctions

Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types –  adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as  epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as  heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Tension Response at Adherens Junctions01:26

Tension Response at Adherens Junctions

The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.
α-Catenin as a Mechanosensory Protein
The α-catenin of adherens junctions is an allosteric protein with three VH (vinculin homology) domains...
