Ans: Biotechnology has revolutionised cancer treatment, with recent advancements focusing on precision medicine, gene therapy, and immunotherapy. One of the most promising breakthroughs is CAR-T cell therapy, which harnesses the body’s immune system to target and destroy cancer cells. The integration of biotechnology in cancer research is leading to more effective, personalised, and less invasive treatments.

Approaches of Biotechnology Research in Cancer Treatment

CAR-T Cell Therapy: A cutting-edge immunotherapy where T-cells (a type of white blood cell) are genetically engineered to recognise and attack cancer cells. It has shown remarkable success in treating blood cancers like leukaemia and lymphoma.
Gene Editing (CRISPR-Cas9): This technique allows precise modifications in DNA to eliminate cancer-causing mutations or enhance immune system response.
Monoclonal Antibodies: Lab-engineered antibodies that bind to cancer-specific antigens, blocking their growth and marking them for immune destruction.
Oncolytic Virus Therapy: Uses genetically modified viruses to selectively infect and kill cancer cells while stimulating an immune response.
Personalised Cancer Vaccines: Tailored to an individual’s tumour profile, these vaccines enhance immune recognition and attack of cancer cells.

Applications of Biotechnology in General

Healthcare and Medicine:
1. Genetic engineering for treating genetic disorders like cystic fibrosis and sickle cell anaemia.
2. Stem cell therapy for regenerative medicine, aiding in tissue repair and organ regeneration.
3. Biopharmaceuticals like insulin, growth hormones, and vaccines.
Industrial Biotechnology:
1. Biofuels derived from microorganisms and agricultural waste.
2. Biodegradable plastics replacing petroleum-based products.
3. Enzymes in detergents and food processing improve efficiency and sustainability.
Environmental Biotechnology:
1. Bioremediation using microorganisms to clean oil spills and detoxify pollutants.
2. Waste management through bio-composting and sewage treatment.

Applications of Biotechnology in Agriculture

Genetically Modified (GM) Crops: Crops like Bt-cotton and Golden Rice are engineered for higher yield, pest resistance, and improved nutritional value.
Biofertilizers and Biopesticides:
1. Nitrogen-fixing bacteria (e.g., Rhizobium) enhance soil fertility naturally.
2. Biopesticides (e.g., Bacillus thuringiensis) offer an eco-friendly alternative to chemical pesticides.
Marker-Assisted Breeding: Helps in developing drought-resistant and disease-resistant crops without genetic modification.
Animal Biotechnology:
1. Genetic improvement of livestock for better disease resistance and productivity.
2. In-vitro fertilisation and cloning for preserving endangered species and enhancing breeding.

Biotechnology has significantly advanced cancer treatment, particularly with CAR-T cell therapy and gene editing techniques. Beyond healthcare, its applications in agriculture, environment, and industry are driving sustainability and innovation. In the agricultural sector, biotechnology is enhancing food security, sustainability, and resistance to climate change. To fully harness these benefits, further research, ethical considerations, and policy support are essential for responsible biotechnological advancements.
