Insights

Vascular targeted therapy offers a novel anticancer strategy by disrupting tumor blood vessels, potentially enhancing traditional treatments. This approach shows broad applicability for solid tumors by selectively targeting their unique vasculature.

Area of Science:

  • Oncology
  • Vascular Biology
  • Drug Discovery

Background:

  • Solid tumors rely on the circulatory system for nutrients and waste removal.
  • Tumor vasculature exhibits molecular differences compared to normal blood vessels.
  • Vascular targeted therapy exploits these differences to selectively attack tumor blood supply.

Purpose of the Study:

  • To explore vascular targeted therapy as an anticancer strategy.
  • To investigate methods for developing selective chemotherapies that target tumor vasculature.
  • To identify potential therapeutic applications by targeting tumor vessel endothelial cells.

Main Methods:

  • Utilizing molecular heterogeneity between normal and tumor vasculature.
  • Developing angiogenesis inhibitors and vascular disrupting agents.
  • Employing expression profiling, gene expression analysis, and phage display libraries to identify targeting peptides.

Main Results:

  • Identification of candidate peptides that bind to tumor vessel endothelial cells.
  • Demonstration of the potential for targeted delivery of chemotherapeutic agents.
  • Validation of vascular targeted therapy as a complementary approach to traditional cancer treatments.

Conclusions:

  • Vascular targeted therapy presents a promising and broadly applicable strategy against solid tumors.
  • Combining vascular targeted therapy with conventional treatments could yield powerful new anticancer regimens.
  • Targeted peptide identification is a key step towards effective vascular targeted drug delivery.

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 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.
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...
Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
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...
