Insights

CD146 molecule is crucial for blood vessel formation and tumor growth. Blocking CD146 with siRNA significantly suppressed endothelial cell activity, indicating its potential as an anti-angiogenesis therapy target.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Oncology

Background:

  • CD146 molecule identified as a biomarker on vascular endothelium.
  • CD146's involvement in angiogenesis and tumor growth previously suggested.
  • The precise mechanism of CD146's function remained unclear.

Purpose of the Study:

  • To investigate the functional role of CD146 in endothelial cells.
  • To develop a novel CD146 blockade system using siRNA.
  • To assess the impact of CD146 inhibition on endothelial cell activity and angiogenesis.

Main Methods:

  • Development of a CD146 siRNA system for targeted gene silencing.
  • Assessment of CD146 expression at both mRNA and protein levels.
  • Evaluation of human umbilical vein endothelial cell (HUVEC) proliferation, adhesion, and migration.

Main Results:

  • CD146 siRNA effectively and specifically blocked CD146 expression.
  • Significant suppression of HUVEC proliferation observed.
  • Inhibition of HUVEC adhesion and migration demonstrated.

Conclusions:

  • CD146 plays a critical role in vascular endothelial cell function and angiogenesis.
  • CD146 siRNA effectively inhibits endothelial cell activity.
  • CD146 siRNA presents a potential therapeutic strategy for anti-angiogenesis therapy.

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 hydroxylase and factor...

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, which...
