Insights

Diamond nanoparticles and multi-wall nanotubes effectively inhibit blood vessel growth, showing promise for anti-angiogenic tumor therapies. Other carbon nanomaterials had varied effects on angiogenesis.

Area of Science:

  • Biomedical Engineering
  • Materials Science
  • Oncology

Background:

  • Angiogenesis is crucial for tumor growth and metastasis.
  • Carbon nanomaterials are being investigated for their potential anti-angiogenic properties.
  • Understanding the specific effects of different carbon nanomaterials on angiogenesis is essential for therapeutic development.

Purpose of the Study:

  • To compare the anti-angiogenic activities of various carbon nanomaterials.
  • To evaluate the impact of diamond nanoparticles, graphite nanoparticles, graphene nanosheets, multi-wall nanotubes, and C60 fullerenes on blood vessel development.
  • To investigate the molecular mechanisms underlying the observed angiogenic effects.

Main Methods:

  • Utilized the in ovo chick embryo chorioallantoic membrane model to assess angiogenic activity.
  • Quantified blood vessel development in response to different carbon nanomaterials.
  • Analyzed protein levels of pro-angiogenic growth factor receptors, specifically vascular endothelial growth factor receptor.

Main Results:

  • Diamond nanoparticles and multi-wall nanotubes demonstrated significant anti-angiogenic properties.
  • C60 fullerenes promoted blood vessel development, while graphite nanoparticles and graphene had no discernible effect.
  • Diamond nanoparticles were found to decrease the expression of vascular endothelial growth factor receptor.

Conclusions:

  • Diamond nanoparticles and multi-wall nanotubes exhibit potent anti-angiogenic effects.
  • These findings highlight the potential of diamond nanoparticles and multi-wall nanotubes for anti-angiogenic tumor therapy.
  • The differential biological activity of carbon nanomaterials warrants further investigation for targeted therapeutic applications.

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

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...
