Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

3.6K
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...

Overview of the Vascular System

3.6K
The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

7.0K
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

Endothelial cell metabolism fuels blood vessel formation (angiogenesis) and vascular health. Disruptions in this metabolism can lead to vascular disorders, offering new therapeutic targets.

Area of Science:

  • Cellular Metabolism
  • Vascular Biology
  • Biochemistry

Background:

  • Endothelial cells (ECs) are crucial for blood vessel formation (angiogenesis) in both health and disease.
  • Emerging evidence highlights the role of EC metabolism in driving angiogenesis, complementing known growth factors.
  • Understanding EC metabolic pathways is key to comprehending vascular homeostasis and disease.

Purpose of the Study:

  • To provide a comprehensive overview of endothelial cell metabolism.
  • To elucidate the role of specific metabolic pathways (glycolysis, fatty acid oxidation) in EC behavior during angiogenesis.
  • To explore the implications of EC metabolic dysregulation in vascular disorders.

Main Methods:

  • Review of established and novel research on EC metabolism.
  • Analysis of metabolic pathways like glycolysis and fatty acid oxidation in ECs.
  • Discussion of metabolite-driven epigenetic regulation and cell-cell crosstalk.

Main Results:

  • 6-Phosphofructo-2-kinase/fructose-2,6-bisphosphatase-3 (PFKFB3)-driven glycolysis supports ECs at the tip of growing sprouts.
  • Carnitine palmitoyltransferase 1a (CPT1a)-controlled fatty acid oxidation regulates proliferation in stalk ECs.
  • ECs exhibit intricate metabolic wiring, including compartmentalization, epigenetic regulation, and subtype-specific traits.

Conclusions:

  • Endothelial cell metabolism is a critical determinant of angiogenesis and vascular homeostasis.
  • Maladaptation of EC metabolism contributes to vascular disorders, presenting anti-angiogenic therapeutic opportunities.
  • Targeting EC metabolism offers a promising strategy for treating vascular diseases.
