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 Supply01:24

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...

Summary

Malignant gliomas grow by forming new blood vessels (angiogenesis). Understanding this process is key to developing new treatments for these deadly brain tumors.

Area of Science:

  • Oncology
  • Molecular Biology
  • Vascular Biology

Background:

  • Malignant gliomas are aggressive brain tumors with poor patient prognosis despite standard treatments.
  • Tumor growth and progression in gliomas are significantly driven by angiogenesis, the formation of new blood vessels.
  • Current therapeutic strategies have limited impact on extending survival for glioma patients.

Purpose of the Study:

  • To elucidate the molecular mechanisms underlying glioma angiogenesis.
  • To review current and emerging anti-angiogenic therapeutic strategies for malignant gliomas.

Main Methods:

  • Review of scientific literature focusing on glioma biology and angiogenesis.
  • Analysis of molecular pathways involved in tumor-induced blood vessel formation.
