Targeted Cancer Therapies

9.0K
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...

Tumor Immunotherapy

2.0K
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.

Combination Therapies and Personalized Medicine

6.2K
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...

Background:

  • Tumorigenesis involves abnormal cell proliferation, posing significant clinical challenges.
  • Conventional cancer treatments like radiotherapy, chemotherapy, and surgery have notable limitations.
  • Certain anaerobic bacteria, including Salmonella typhimurium, exhibit anti-tumor properties and can selectively colonize tumors.

Purpose of the Study:

  • To review the anti-tumor mechanisms of Salmonella.
  • To summarize research progress in genetically modified Salmonella for tumor therapy.
  • To discuss current challenges and potential solutions in Salmonella-mediated tumor treatment.

Main Methods:

  • Review of existing literature on Salmonella and its anti-tumor applications.
  • Analysis of genetic modifications in Salmonella to enhance tumor specificity and therapeutic delivery.
  • Evaluation of experimental data from animal models using engineered Salmonella.

Main Results:

  • Attenuated Salmonella strains demonstrate selective tumor colonization and growth inhibition.
  • Genetically modified Salmonella serve as effective carriers for anti-tumor therapeutic molecules.
  • Numerous animal experiments show promising anti-tumor effects of engineered Salmonella.

Conclusions:

  • Genetically modified Salmonella offer a promising avenue for advanced tumor therapy.
