Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

2.8K
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.

Adhesion01:14

Adhesion

40.6K
Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.
Capillary action is a result of water’s adhesive tendencies. When a narrow...

Adherens Junctions

5.0K
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

3.1K
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.

Cell Adhesion Molecules - Types and Functions

7.1K
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).
CAM Families
The Integrin family of proteins is primarily  involved...

Activation of Integrins01:15

Activation of Integrins

3.5K
Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...

Background:

  • Post-operative adhesions are a significant cause of morbidity.
  • Epigenetic modifications are implicated in adhesion development.

Purpose of the Study:

  • To investigate epigenetic differences in fibroblasts from normal peritoneum versus adhesion tissues.
  • To identify specific genes with altered DNA methylation patterns.

Main Methods:

  • Fibroblast DNA isolation using Qiagen's EZ1 Advanced Kit.
  • DNA methylation profiling via the Infinium Human Methylation 27 BeadChip system.
  • Comparative analysis of methylation patterns between normal and adhesion fibroblasts.

Main Results:

  • 7364 genes showed significant DNA methylation differences (P<0.01).
  • 1685 genes had increased methylation in adhesion fibroblasts, enriched in glycoprotein and defense response categories.
  • 1287 genes had decreased methylation, enriched in homeobox and transcription factor activity categories.

Conclusions:

  • Significant epigenetic variations exist between normal peritoneal and adhesion fibroblasts.
  • These identified genes represent potential targets for therapeutic interventions.
  • Further research will elucidate the precise role of these epigenetic changes in adhesion formation.
