Insights

Targeting tumor angiogenesis, the growth of tumor blood vessels, is key for cancer control. Combining anti-angiogenesis with radiation may enhance anti-tumor effects and minimize drug resistance.

Area of Science:

  • Oncology
  • Cancer Biology
  • Radiation Oncology

Background:

  • Tumor growth and progression are critically dependent on tumor angiogenesis.
  • Tumor vasculature plays a vital role in radiation response, independent of oxygen levels.
  • Anti-angiogenic therapies face challenges with potential drug resistance due to induced hypoxia.

Purpose of the Study:

  • To explore the potential of combining anti-angiogenesis with ionizing radiation.
  • To investigate synergistic anti-tumor effects and overcome resistance mechanisms.
  • To target both endothelial and tumor cells for enhanced therapeutic outcomes.

Main Methods:

  • Review of current findings on anti-angiogenesis and radiation therapy.
  • Analysis of mechanisms leading to drug resistance in anti-angiogenic therapies.
  • Hypothesizing combination strategies for improved cancer treatment.

Main Results:

  • Anti-angiogenesis can lead to tumor hypoxia, selecting for resistant cells.
  • Combining anti-angiogenesis with radiation may counteract resistance.
  • This combination strategy holds promise for synergistic anti-tumor effects.

Conclusions:

  • Targeting tumor angiogenesis is a crucial strategy in cancer therapy.
  • Combining anti-angiogenesis with radiation offers a promising approach to enhance efficacy.
  • This combined modality may minimize the development of drug resistance and improve tumor regression.

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...

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...
Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
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...
