Current uses of gene therapy to treat cancer are still in experimental stages. A number of clinical trials to study the effects of genes in fighting cancer and prevention against cancer are underway. Several treatment approaches with genes are being used to increase the ability of healthy cells to fight off malignant cells, as well as to destroy the cancer cells with gene therapy.
Gene therapy is an experimental technique that uses genes to treat or prevent disease. In the future, this technique may allow doctors to treat a disorder by inserting a gene into a patient’s cells instead of using drugs or surgery. Researchers are testing several approaches to gene therapy, including:
Gene therapy may use the genetic material, DNA, itself as the means of treatment. DNA or deoxyribonucleic acid is the very long molecule that encodes the genetic information. A gene is a stretch of DNA required to make a functional product such as part or all of a protein. People have about 100,000 to 150,000 genes.
Gene therapy uses sections of DNA (usually genes) to treat or prevent disease.; The DNA is carefully selected to correct the effect of a mutated gene that is causing disease. The technique was first developed in 1972 but has, so far, had limited success in treating human diseases.
In the medicine field gene therapy (also called human gene transfer) is the therapeutic delivery of nucleic acid into a patient's cells as a drug to treat disease. The first attem
The eye turns out to be a convenient compartment for gene therapy. The retina, on the inside of the eye, is both easy to access and partially protected from the immune system. And viruses can't move from the eye to other places in the body. Most gene-therapy vectors used in the eye are based on AAV (adeno-associated virus).
Read all about gene therapy including current medical research on switching therapeutic genes on and off, light-activated gene therapy and gene silencing.
Gene therapy is an experimental form of treatment. It works by replacing a faulty disease-causing gene with a working version, or by introducing a new gene to cure a condition or modify its effects. The aim is to eliminate genetic diseases at their source. The challenge for nations experimenting ...
List of Disadvantages of Gene Therapy. 1. It can damage the gene pool. It is believed that gene therapy could possibly change the human gene pool permanently if it was done to a certain degree. Aside from this, this type of treatment will most likely be for the rich only, indefinitely making the rich richer and the poor poorer. 2.
Gene therapy holds promise for treating a wide range of diseases, such as cancer, cystic fibrosis, heart disease, diabetes, hemophilia and AIDS. Researchers are still studying how and when to use gene therapy. Currently, in the United States, gene therapy is available only as part of a clinical trial.
