Insights

Targeting tumor angiogenesis, particularly vascular endothelial growth factor (VEGF), has shown success. New angiogenesis inhibitors are being developed to overcome therapy resistance by targeting endothelial cell behaviors.

Area of Science:

  • Oncology
  • Cancer Biology
  • Molecular Medicine

Background:

  • Tumor growth depends on angiogenesis (new blood vessel formation).
  • Vascular Endothelial Growth Factor (VEGF)-targeted therapies have achieved clinical success in oncology.
  • Resistance to VEGF-targeted antiangiogenic therapy is a significant clinical challenge.

Purpose of the Study:

  • To provide a conceptual framework for developing novel antiangiogenic agents.
  • To discuss molecular discoveries and principles relevant to clinical antiangiogenesis strategies.
  • To identify new therapeutic targets beyond VEGF for cancer treatment.

Main Methods:

  • Review of molecular discoveries related to endothelial cell behavior in angiogenesis.
  • Analysis of endothelial 'tip, stalk, and phalanx' cell functions.
  • Integration of basic science findings with clinical opportunities.

Main Results:

  • Identification of endothelial cell behaviors as promising targets for complementary antiangiogenic mechanisms.
  • Understanding of how endothelial tip, stalk, and phalanx cells contribute to sprout formation.
  • Framework for developing next-generation antiangiogenic drugs.

Conclusions:

  • New antiangiogenic agents targeting endothelial cell dynamics offer potential to overcome VEGF-inhibitor resistance.
  • A deeper understanding of angiogenesis mechanisms can guide the development of more effective cancer therapies.
  • Clinical translation of novel molecular targets is crucial for advancing antiangiogenic medicine.

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...
Cell Migration01:19

Cell Migration

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.
Cell Migration01:09

Cell Migration

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.
Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Chemotaxis and Direction of Cell Migration01:21

Chemotaxis and Direction of Cell Migration

Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon towards...
