Insights

Tocotrienol, a vitamin E compound, effectively inhibits endothelial cell proliferation and network formation. This suggests tocotrienol

Area of Science:

  • Biochemistry
  • Cell Biology
  • Nutritional Science

Background:

  • Angiogenesis, the formation of new blood vessels, is crucial for development and implicated in various diseases.
  • Modulating angiogenesis is a therapeutic strategy for angiogenesis-mediated disorders.
  • Vitamin E compounds, including tocopherols and tocotrienols, are investigated for their biological activities.

Purpose of the Study:

  • To investigate the anti-angiogenic properties of vitamin E compounds, specifically tocotrienol.
  • To compare the effects of tocotrienol and tocopherol on endothelial cell behavior.

Main Methods:

  • Utilized well-characterized in vitro systems.
  • Assessed the proliferation of bovine aortic endothelial cells.
  • Evaluated the formation of endothelial cell networks in 3D collagen gels.

Main Results:

  • Tocotrienol significantly inhibited endothelial cell proliferation in a dose-dependent manner at low micromolar concentrations.
  • Tocopherol did not exhibit similar inhibitory effects on cell proliferation.
  • Tocotrienol markedly reduced the formation of endothelial cell networks within 3D collagen gels.

Conclusions:

  • Tocotrienol demonstrates potent anti-angiogenic properties in vitro.
  • Tocotrienol is a potential candidate for therapeutic agents or preventive food factors targeting tumor angiogenesis.

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...
