Targeted Cancer Therapies

9.2K
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...

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 Medicine

6.4K
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...

Electron Transport Chain: Complex I and II

19.7K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Area of Science:

  • Biomedical Engineering
  • Nanomedicine
  • Cancer Therapy

Background:

  • Chemodynamic therapy (CDT) leverages the tumor microenvironment's unique conditions (high H2O2, mild acidity) for cancer treatment.
  • Iron-based catalysts are ideal for CDT due to biocompatibility, tumor targeting, and theragnostic potential.
  • Tumor microenvironment limitations can hinder iron-based CDT efficacy.

Purpose of the Study:

  • To review the mechanisms of iron-based CDT.
  • To summarize advanced iron-based nanomaterials designed to overcome CDT limitations.
  • To highlight strategies for enhancing CDT efficacy and discuss clinical translation challenges.

Main Methods:

  • Review of iron-based chemodynamic therapy mechanisms.
  • Analysis of tumor microenvironment limitations.
  • Summary of inorganic, organic-inorganic hybrid, and biomimetic nanostructures for CDT.
  • Discussion of strategies including TME modulation, external stimuli, and combination therapies.

Main Results:

  • Iron-based CDT generates hydroxyl radicals via Fenton reactions for selective tumor ablation.
  • Advanced nanomaterials (inorganic, hybrid, biomimetic) address TME challenges.
  • Strategies like TME remodeling, external stimuli, and synergistic therapies enhance CDT efficacy.
  • Key challenges and future directions for clinical translation are outlined.

Conclusions:

  • Iron-based CDT is a promising cancer treatment strategy.
  • Nanomaterial design and multidimensional strategies are crucial for overcoming limitations.
  • Further research is needed for successful clinical translation of iron-based CDT.
