Invasion & Metastasis
|January 1, 1994
Summary
Melanoma progression involves significant changes in cell adhesion receptors. Key adhesion molecules like E-cadherin and Mel-CAM, along with integrins, are altered during the development of melanoma from precursor lesions.
Area of Science:
- Dermatology
- Cancer Biology
- Cell Biology
Background:
- Melanoma develops from precursor lesions with distinct histological features.
- Cell adhesion molecules play crucial roles in regulating cell-cell interactions and tissue organization.
- Alterations in adhesion receptor expression are implicated in cancer progression.
Purpose of the Study:
- To review major changes in adhesion receptor expression during melanoma progression.
- To highlight the role of adhesion molecules in the transition from normal melanocytes to melanoma.
- To understand the molecular mechanisms underlying melanoma development.
Main Methods:
- Literature review of studies on melanoma and cell adhesion.
- Analysis of changes in adhesion receptor expression at different stages of melanoma development.
- Focus on key adhesion molecules like E-cadherin, Mel-CAM, and integrins.
Main Results:
- Loss of E-cadherin and gain of Mel-CAM during melanocyte to benign nevus transition.
- Upregulation of integrin subunit beta 3 in late-stage melanomas.
- Downregulation of integrins alpha 6 beta 1 and alpha V beta 1 during melanoma progression.
Conclusions:
- Adhesion receptor expression undergoes significant alterations throughout melanoma development.
- These changes in adhesion molecules are critical for melanoma progression and tumorigenesis.
- Targeting adhesion pathways may offer therapeutic strategies for melanoma.

01:35Cancer 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...
01:10Integrins
Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...

01:17Intracellular Signaling Affects Focal Adhesions
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

01:20Cell Adhesion Molecules - Types and Functions
Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).

01:25Selectins
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...
01:31Immunoglobulin-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...
