Background:
Cancer is a genetic disease and mainly arises due to a number of reasons include activation of onco-genes, malfunction of tumor suppressor genes or mutagenesis due to external factors.
Methods:
This article was written from the data collected from PubMed, Nature, Science Direct, Springer and Elsevier groups of journals.
Results:
Oncogenes are deregulated form of normal proto-oncogenes required for cell division, differentiation and regulation. The conversion of proto-oncogene to oncogene is caused due to translocation, rearrangement of chromosomes or mutation in gene due to addition, deletion, duplication or viral infection. These oncogenes are targeted by drugs or RNAi system to prevent proliferation of cancerous cells. There have been developed different techniques of molecular biology used to diagnose and treat cancer, including retroviral therapy, silencing of oncogenes and mutations in tumor suppressor genes.
Conclusion:
Among all the techniques used, RNAi, zinc finger nucleases and CRISPR hold a brighter future towards creating a Cancer Free World.
Insights
Cancer arises from genetic mutations, including oncogene activation. Advanced techniques like RNA interference (RNAi), zinc finger nucleases, and CRISPR offer promising cancer treatment strategies for a cancer-free future.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Cancer is fundamentally a genetic disease.
- It stems from oncogene activation, tumor suppressor gene malfunction, or external mutagenesis.
- Understanding these genetic underpinnings is crucial for developing effective treatments.
Purpose of the Study:
- To review current understanding of cancer genetics and molecular mechanisms.
- To explore advanced molecular techniques for cancer diagnosis and treatment.
- To highlight future directions in cancer research and therapy.
Main Methods:
- Literature review of scientific journals (PubMed, Nature, Science Direct, Springer, Elsevier).
- Analysis of data on oncogene deregulation and its causes.
- Examination of molecular biology techniques for cancer intervention.
Main Results:
- Oncogenes are altered proto-oncogenes critical for cell regulation; their dysregulation drives cancer.
- Gene alterations (translocation, mutation, viral infection) convert proto-oncogenes to oncogenes.
- Molecular techniques like RNAi can target oncogenes to inhibit cancer cell proliferation.
Conclusions:
- RNA interference (RNAi), zinc finger nucleases, and CRISPR gene editing show significant promise.
- These advanced technologies are pivotal for future cancer treatment strategies.
- They offer a pathway towards achieving a cancer-free world.

Cancer Therapies
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...
