Summary
Radiation therapy resistance in cancer is a major challenge. Nucleic acid-based therapies show promise in restoring cancer cell sensitivity to radiation by targeting key resistance mechanisms.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Radiation therapy is a common cancer treatment, but tumor cells can develop resistance.
- Mechanisms of resistance include hypoxia, cell cycle deregulation, apoptosis evasion, and enhanced DNA repair.
- This resistance leads to treatment failure and disease recurrence.
Purpose of the Study:
- To review nucleic acid-based strategies for overcoming radioresistance.
- To evaluate the potential of these therapies in combination with radiotherapy.
Main Methods:
- Focus on five classes of nucleic acid-based approaches: gene transfer, immune-stimulating oligonucleotides, antisense oligonucleotides, siRNA/shRNA, and siDNA.
- Targeting specific proteins or pathways involved in radioresistance.
Main Results:
- Review of preclinical studies and clinical trials combining nucleic acid therapies with radiotherapy.
- Assessment of the efficacy of these combined approaches in preclinical models and early-phase human trials.
Conclusions:
- Nucleic acid-based molecular therapies offer promising strategies to enhance radiotherapy efficacy.
- Further research and clinical trials are needed to fully realize the potential of these combined treatments.

02:57Targeted 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.

02:49Cancer 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...

01:27Tumor 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.
02:50Combination 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...
