Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.6K
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...

Gene Therapy00:59

Gene Therapy

25.4K
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...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

13.1K
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...

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

7.6K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

4.9K
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...

In-vitro Mutagenesis01:16

In-vitro Mutagenesis

13.9K
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Area of Science:

  • Biomedical Engineering
  • Molecular Biology
  • Cancer Therapeutics

Background:

  • Targeting cancer cell mitochondria is a promising therapeutic strategy.
  • Current methods for specifically destroying cancer mitochondria in vivo are limited.

Approach:

  • Developed mLumiOpto, a mitochondrial-targeted luminoptogenetics gene therapy.
  • Engineered blue light-gated channelrhodopsin (CoChR) in the inner mitochondrial membrane (IMM) and Nanoluciferase (NLuc) in the cytosol.
  • Delivered mLumiOpto genes to cancer cells using adeno-associated virus (AAV) with cancer-specific promoters or exosome-associated AAV.

Key Points:

  • NLuc bioluminescence activation of mitochondrial CoChR disrupts IMM potential.
  • Induces mitochondrial damage and subsequent cancer cell death.
  • Demonstrated efficacy in reducing tumor burden in glioblastoma and triple-negative breast cancer models.

Conclusions:

  • mLumiOpto is a novel and effective therapeutic strategy for targeting cancer cell mitochondria in vivo.
  • This approach offers a new avenue for cancer treatment by selectively inducing cancer cell death.
