Insights

Anti-angiogenic therapies target tumor blood vessels to treat cancers like colon and lung cancer. However, understanding tumor resistance mechanisms is crucial for improving treatment efficacy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Context:

  • Anti-angiogenic therapies are a novel treatment for solid tumors, improving survival in various cancers.
  • Tumor resistance significantly limits the efficacy of these therapies.

Purpose:

  • To review the molecular and cellular mechanisms of tumor angiogenesis.
  • To describe the factors controlling angiogenesis activation and maturation.
  • To discuss the efficacy, limits, and resistance mechanisms of current anti-angiogenic therapies.

Summary:

  • This review details tumor angiogenesis, focusing on hypoxia, vascular endothelial growth factor (VEGF), and endothelial tip cells.
  • It explains the mechanisms of angiogenesis activation and maturation.
  • The review also covers the effectiveness and limitations of existing anti-angiogenic drugs and explores emerging resistance mechanisms.

Impact:

  • Provides a comprehensive overview of tumor angiogenesis and anti-angiogenic therapy resistance.
  • Highlights the need for further research into overcoming therapeutic limitations.
  • Informs the development of more effective cancer treatment strategies.

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...
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...
The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
Targeted Cancer Therapies02:57

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...
Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
