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...
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...

Summary

Indirubin derivative E804 (IDR-E804) effectively inhibits angiogenesis by reducing endothelial cell proliferation, migration, and tube formation. This compound also demonstrates anti-tumor efficacy by suppressing tumor growth and vascularization in vivo.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Biology

Background:

  • Indirubin derivative E804 (IDR-E804) previously shown to inhibit STAT-3 signaling and Src kinase.
  • IDR-E804's role in angiogenesis requires further investigation.

Purpose of the Study:

  • To evaluate the anti-angiogenic potential of IDR-E804 using human umbilical vein endothelial cells (HUVECs).
  • To analyze the effects of IDR-E804 on cellular and molecular events critical for angiogenesis.
  • To assess the in vivo efficacy of IDR-E804 in inhibiting tumor growth.

Main Methods:

  • Assessed HUVEC proliferation, migration, and capillary tube formation induced by vascular endothelial growth factor (VEGF) with varying IDR-E804 concentrations.
  • Investigated IDR-E804's effect on angiogenesis and tumor growth in a mouse model (CT-26 colon cancer cells).

Main Results:

  • IDR-E804 significantly reduced VEGF-induced HUVEC proliferation, migration, and tube formation.
  • Observed decreased phosphorylation of VEGFR-2, AKT, and ERK in HUVECs treated with IDR-E804.
  • IDR-E804 treatment led to reduced tumor growth, decreased microvessel density (CD31), and proliferation (Ki-67), with increased apoptosis in tumors.

Conclusions:

  • IDR-E804 acts as a potent inhibitor of angiogenesis.
  • IDR-E804 shows promise as an effective anti-tumor therapeutic agent.
