Insights

Anti-angiogenic drugs targeting the vascular endothelial growth factor system show unconvincing efficacy in advanced breast cancer. Further research and biomarkers are needed to identify suitable patients for these cancer therapies.

Area of Science:

  • Oncology
  • Cancer Biology
  • Pharmacology

Background:

  • Neo-angiogenesis, the formation of new blood vessels, is crucial for tumor growth and metastasis.
  • Targeting the vascular endothelial growth factor (VEGF) system is a key strategy in anti-cancer therapy.

Purpose of the Study:

  • To review the efficacy of three anti-angiogenic agents (bevacizumab, ramucirumab, sorafenib) targeting the VEGF system in advanced breast cancer.
  • To assess the role of these agents in adjuvant and neo-adjuvant settings.

Main Methods:

  • Review of clinical trials evaluating anti-angiogenic drugs in advanced breast cancer.
  • Analysis of treatment outcomes and tumor response variability.

Main Results:

  • Observed clinical improvements with anti-angiogenic drugs in advanced breast cancer have been unconvincing to date.
  • Outcomes of anti-angiogenic therapy show significant variability in tumor response.

Conclusions:

  • Further research is required to establish the efficacy of anti-angiogenic drugs in breast cancer treatment.
  • Development of biomarkers and molecular profiling is essential to identify patients who will benefit from anti-angiogenic therapy, improving cost-effectiveness.

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...

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...

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...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...
