What is Genome Editing?
Genome editing technology is a scientific process in which a specific part of the genome i.e. DNA is changed. This process takes place inside the cells. Genome Editing Technology in Healthcare: Genome editing is an emerging technology that is bringing revolutionary changes in the medical field. This technology provides the ability to modify the genes present in the human genome. Through this, gene-related diseases can be cured, for which no treatment was possible till now. In simple words, with genome editing, scientists can correct any kind of mistake or defect within the gene.
It is used to control the subtle activities that take place. DNA is present in every cell of our body, which determines our physical structure and properties. Genome editing technology can be used to cure diseases, develop new medical methods and enhance the natural capabilities of the body by changing DNA.
CRISPR-Cas9
There are many techniques of genome editing, but the most special and popular technique among them is CRISPR-Cas9. With the help of this technique, scientists can cut and change a particular part of DNA with great precision. The full form of CRISPR is “Clustered Regularly Interspaced Short Palindromic Repeats”, and Cas9 is a type of enzyme that cuts DNA. This technique has made genome editing even easier and more effective.
Use of Genome Editing in Healthcare
Genome editing technology is being used in healthcare to diagnose and treat diseases. Some of the main areas where it is being widely used are:
Treatment of Genetic Diseases: Genetic diseases are those that are passed from parents to offspring through genes. such as Huntington’s disease, sickle cell anemia, and cystic fibrosis. Genome editing can treat these diseases by modifying the genes responsible for them.
Treatment of Cancer:Uncontrolled cell proliferation is a complicated aspect of cancer. By restoring the altered genes in cancer cells, genome editing aids in the therapy of cancer. This can also increase the immunity of patients against cancer.
Dealing with antibiotic resistance: At present, many bacteria have developed resistance to antibiotics. With the help of genome editing, antibiotic resistance can be reduced by changing the structure of bacteria, which can make the treatment of serious infections effective.
Immunotherapy: Immunotherapy is a new treatment method, in which the immune system of the body is prepared in such a way using genome editing that it can fight diseases on its own. This technique is proving to be particularly effective in the treatment of diseases like cancer.
Benefits of genome editing technology
- Genome editing technology is very accurate, which helps in curing potential diseases from the root.
- Once the gene is corrected by genome editing, the risk of reappearance of the disease is reduced.
- This technology has the ability to completely eliminate genetic diseases, so that these diseases do not remain in future generations as well.
Challenges of genome editing
Although this technology is full of immense possibilities, it also has some challenges.
- Ethical and legal questions are being raised regarding the use of genome editing. Such as is it right to change human genes? And how to prevent misuse of this technology?
- The processes of genome editing are still expensive, making it a challenge to provide its benefits to the common people.
- Sometimes some unexpected results can also occur during genome editing, which can cause other diseases.
Conclusion
Genome editing technology is emerging as a new hope in healthcare. This technology has opened new paths in the medical field, making it possible to treat many serious and genetic diseases. Although there are challenges, its benefits and possibilities are unlimited. If the right solution to ethical and legal issues is found, then this technology can prove to be a major revolution in human health.
