Insights

Distant metastasis in renal cell carcinoma is a major challenge. Loss of cell adhesion molecules called cadherins may facilitate tumor cell detachment and spread, impacting patient prognosis.

Area of Science:

  • Oncology
  • Cell Biology
  • Molecular Pathology

Background:

  • Distant metastasis presents a significant clinical challenge in renal cell carcinoma (RCC).
  • Tumor cell detachment and circulation are critical early steps in the metastatic cascade.
  • Cadherins, cell adhesion molecules, are hypothesized to play a role in tumor cell detachment.

Purpose of the Study:

  • To investigate the role of cadherins in renal cell carcinoma pathogenesis.
  • To understand how cadherin expression influences tumor cell detachment and metastasis.
  • To clarify the specific functions of N-cadherin, E-cadherin, ksp-cadherin, and cadherin 6 in RCC.

Main Methods:

  • Analysis of cadherin expression in normal kidney and renal cell carcinoma tissues.
  • Review of existing literature on cadherin function in metastasis.
  • Correlation of cadherin expression with clinical data and patient prognosis (implied).

Main Results:

  • Loss of E-cadherin has been linked to invasion and metastasis in animal models.
  • E-cadherin downregulation is associated with poor prognosis in cancer patients.
  • Four cadherins (N-cadherin, E-cadherin, ksp-cadherin, cadherin 6) are present in kidney and RCC.

Conclusions:

  • Cadherin-mediated cell adhesion is a critical factor in renal cell carcinoma metastasis.
  • Understanding the specific roles of different cadherins is essential for developing targeted therapies.
  • Further research is needed to elucidate the precise mechanisms by which cadherins contribute to RCC progression.

Structure of Cadherins01:25

Structure of Cadherins

The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins”   is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This diversity of cadherins...
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.
Adherens Junctions are Dynamic
The endothelial cells...
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.

Immunoglobulin-like Cell Adhesion Molecules01:31

Immunoglobulin-like Cell Adhesion Molecules

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...
Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal01:22

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
