Immunoglobulin-like Cell Adhesion Molecules01:31

Immunoglobulin-like Cell Adhesion Molecules

3.2K
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...

Intracellular Signaling Affects Focal Adhesions

2.6K
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.

MicroRNAs01:22

MicroRNAs

21.3K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Cancer Biology

Background:

  • The IgLON family (LSAMP, OPCML, neurotrimin, NEGR1, IgLON5) are cell adhesion molecules crucial for neuronal development and synapse maintenance.
  • Emerging evidence highlights their tumor suppressor functions via modulation of oncogenic pathways.

Purpose of the Study:

  • To review the current understanding of non-coding RNAs, specifically long non-coding RNAs and microRNAs, in regulating IgLON family member expression.
  • To explore the impact of this regulation on both physiological functions and pathological conditions.

Main Methods:

  • Literature review of studies investigating non-coding RNA interactions with IgLON members.
  • Analysis of findings related to LSAMP, OPCML, neurotrimin, NEGR1, and IgLON5 expression and function.

Main Results:

  • Non-coding RNAs significantly modulate LSAMP expression in senescence, cancer, addiction, and pulmonary hypertension.
  • MicroRNAs are implicated in OPCML and neurotrimin regulation in tumorigenesis and nerve injury.
  • MicroRNA involvement in NEGR1 is studied in ischemic injury, tumorigenesis, and endothelial dysfunction.
  • Limited data exist for IgLON5, with microRNAs linked to myocardial infarction.

Conclusions:

  • Non-coding RNAs play a critical role in controlling IgLON expression.
  • This modulation impacts essential physiological functions and contributes to various pathologies.
  • Further research is needed to fully elucidate these complex regulatory networks.
