Insights

Targeting inflammation offers a novel strategy to inhibit tumor angiogenesis. By understanding how immune cells promote blood vessel growth, we can develop new treatments to prevent cancer progression.

Area of Science:

  • Oncology
  • Immunology
  • Vascular Biology

Background:

  • Tumor growth relies heavily on angiogenesis, the formation of new blood vessels.
  • Current antiangiogenic therapies target endothelial cells, showing some success in improving cancer patient survival.
  • Immune cells within tumors also stimulate endothelial cells, contributing to tumor vascularization through inflammation-dependent pathways.

Purpose of the Study:

  • To explore the role of inflammation-driven angiogenesis in tumor growth.
  • To identify novel therapeutic targets beyond endothelial cells for antiangiogenic therapy.
  • To propose chemoprevention of inflammatory angiogenesis as a strategy to control cancer progression.

Main Methods:

  • Literature review on angiogenesis, tumor vascularization, and anti-inflammatory drug mechanisms.
  • Analysis of the interplay between immune cells, endothelium, and tumor growth.
  • Conceptualization of chemoprevention strategies targeting inflammatory angiogenesis.

Main Results:

  • Tumor vascularization is not solely dependent on direct endothelial cell targeting; immune cells play a crucial indirect role.
  • Inflammation is a key driver of tumor angiogenesis, suggesting anti-inflammatory approaches are viable.
  • Nonsteroidal anti-inflammatory drugs demonstrate angiogenesis inhibition, supporting the link between inflammation and vascularization.

Conclusions:

  • Targeting inflammation-dependent angiogenesis presents a promising avenue for cancer therapy and prevention.
  • Utilizing agents with anti-inflammatory properties offers a strategy for angioprevention.
  • Chemoprevention of inflammatory angiogenesis could be an effective method for early cancer control.

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...

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...
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.
Cancer02:18

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
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...
