Insights

The NC1 domain of type XIX collagen inhibits melanoma cell migration, not proliferation. This finding may help explain how this collagen domain slows tumor growth.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Oncology

Background:

  • Type XIX collagen is a minor collagen found in basement membrane zones.
  • The C-terminal NC1 domain of type XIX collagen (NC1(XIX)) has previously shown in vivo tumor growth inhibition.

Purpose of the Study:

  • To investigate the effects of the NC1(XIX) collagen domain on melanoma cell migratory behavior.
  • To determine if NC1(XIX) impacts melanoma cell proliferation.

Main Methods:

  • Melanoma cell lines (B16F10 and UACC 903) were treated with varying concentrations of NC1(XIX).
  • Cell proliferation assays were performed.
  • Cell migration was assessed using the scratch wound model and Ibidi® devices.

Main Results:

  • NC1(XIX) did not inhibit melanoma cell proliferation.
  • NC1(XIX) significantly reduced melanoma cell migration speed in a dose-dependent manner.
  • Reduced migration was observed in both murine (B16F10) and human (UACC 903) melanoma cells.

Conclusions:

  • The NC1(XIX) domain inhibits melanoma cell migration.
  • This anti-migratory effect may contribute to the previously observed inhibition of tumor growth.
  • Further research is needed to elucidate the underlying molecular mechanisms of migration inhibition.

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...

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...
Cell Migration01:19

Cell Migration

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Cell Migration

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.
Role of Myosin in Cell Migration01:18

Role of Myosin in Cell Migration

Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common type in animal cells, which binds and cross-links actin filaments.
Myosin II  is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction. It is...
Fibril-associated Collagen01:11

Fibril-associated Collagen

Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...
