Insights

Soluble endothelial cell-selective adhesion molecule (sESAM) predicts future atherosclerotic cardiovascular disease (ASCVD) events. Unlike other adhesion molecules, sESAM shows a significant association with incident ASCVD, highlighting its potential as a biomarker.

Area of Science:

  • Cardiovascular Medicine
  • Biomarkers
  • Atherosclerosis Research

Background:

  • Cell adhesion molecules regulate atherosclerotic plaque development.
  • Soluble intercellular adhesion molecule (sICAM-1) and vascular cell adhesion molecule (sVCAM-1) have conflicting associations with atherosclerotic cardiovascular disease (ASCVD).
  • Endothelial cell-selective adhesion molecule (ESAM) is expressed in platelets and endothelial cells; soluble ESAM (sESAM) is linked to subclinical atherosclerosis.

Purpose of the Study:

  • To investigate the association between soluble endothelial cell-selective adhesion molecule (sESAM) and incident atherosclerotic cardiovascular disease (ASCVD).
  • To compare the predictive value of sESAM with sICAM-1 and sVCAM-1 for ASCVD events.

Main Methods:

  • Measured sESAM, sICAM-1, and sVCAM-1 in 2,442 participants without prevalent CVD (Dallas Heart Study).
  • Followed participants for incident ASCVD events (myocardial infarction, stroke, revascularization, CV death) over 10.4 years.
  • Utilized Cox proportional hazards models and assessed model discrimination and reclassification.

Main Results:

  • Elevated sESAM levels were independently associated with a higher risk of incident ASCVD (HR Q4 vs Q1: 2.7).
  • This association remained significant after adjusting for traditional risk factors, renal function, sICAM-1, sVCAM-1, and coronary calcium.
  • sESAM addition improved risk prediction models for ASCVD (P = .009 for c-index, P = .001 for IDI, NRI = 0.42).
  • Neither sICAM-1 nor sVCAM-1 showed independent associations with incident ASCVD.

Conclusions:

  • Soluble endothelial cell-selective adhesion molecule (sESAM) levels are associated with incident atherosclerotic cardiovascular disease (ASCVD).
  • sESAM demonstrates predictive value for ASCVD events, independent of traditional risk factors.
  • Further research is needed to elucidate the specific role of sESAM in ASCVD pathogenesis.

Selectins

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,...

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Intracellular 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.
