Insights

Tumor growth relies on angiogenesis, the formation of new blood vessels. This review explores tumor angiogenesis signaling pathways and antiangiogenic therapies targeting cancer growth.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Angiogenesis, the formation of new blood vessels, is crucial for tumor growth, survival, and proliferation.
  • First proposed in 1971, the concept of targeting angiogenesis has significantly impacted cancer research and therapeutic strategies.
  • Despite decades of research and clinical application of antiangiogenic agents, the complex multistep process of angiogenesis remains incompletely understood.

Purpose of the Study:

  • To review the key signaling pathways involved in tumor angiogenesis.
  • To discuss antiangiogenic agents that have been approved or are under investigation for cancer therapy.
  • To provide an updated overview of the field for researchers and clinicians.

Main Methods:

  • Literature review of scientific publications on tumor angiogenesis.
  • Analysis of signaling pathways regulating angiogenesis in cancer.
  • Compilation of data on approved and investigational antiangiogenic agents.
  • Focus on agents approved by the U.S. Food and Drug Administration (FDA) or in clinical trials.

Main Results:

  • Identified critical signaling pathways, including VEGF, FGF, and angiopoietins, that drive tumor angiogenesis.
  • Summarized the mechanisms of action for various antiangiogenic drugs.
  • Highlighted the clinical success and limitations of current antiangiogenic therapies.
  • Presented a comprehensive list of FDA-approved and investigational antiangiogenic agents.

Conclusions:

  • Targeting tumor angiogenesis remains a promising strategy in cancer therapy.
  • Further elucidation of complex angiogenesis pathways is needed for developing more effective treatments.
  • Combination therapies involving antiangiogenic agents may overcome resistance and improve patient outcomes.
  • Continued research into novel antiangiogenic agents and targets is essential for advancing cancer care.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

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...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
