Insights

Targeting tumor blood vessel growth (angiogenesis) is key for cancer therapy. Gene therapy offers sustained delivery of anti-angiogenic agents, with choices in inhibitors and delivery methods crucial for success.

Area of Science:

  • Oncology
  • Gene Therapy
  • Molecular Biology

Background:

  • Tumor growth and metastasis are dependent on angiogenesis.
  • Targeting tumor vasculature is a promising anticancer strategy.
  • Molecular insights have led to various antiangiogenic therapies.

Purpose of the Study:

  • To review gene therapy-mediated antiangiogenic strategies.
  • To discuss key variables in designing gene therapy approaches for cancer.
  • To provide examples from preclinical models.

Main Methods:

  • Review of antiangiogenic agents and gene delivery methods.
  • Analysis of target/site selection for transgene expression.
  • Illustrative examples from preclinical studies.

Main Results:

  • Gene therapy offers sustained expression of antiangiogenic agents.
  • Several antiangiogenic strategies and gene delivery methods are available.
  • Preclinical models demonstrate the potential of these approaches.

Conclusions:

  • Gene therapy is a viable approach for delivering antiangiogenic agents.
  • Careful consideration of inhibitor, delivery method, and target site is essential.
  • Further preclinical research is warranted to optimize these strategies.

Gene Therapy00:59

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be inserted. The...

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...
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...
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.
