Gene Therapy mechanics of Action | Several approaches of Gene Therapy.

Treatment is all about curing the disorder affecting the normal health of a person. It includes a better understanding of causative factors for the onset of a health problem, the precautionary steps, and the important medication. Recent achievements in genetic medication have tiled the way for wide-ranging therapies positioning the foundation for next-generation technologies. Nowadays, there exist are many treatments to cure a patient having any disease. One among them is gene therapy. Let us have a glance at the technique in detail.

What is a gene?

A gene is the basic physical, functional and fundamental unit of heredity which is located on the DNA comprised in each of our living cells. The set of genes in any organism is defined as a genome with approximately 20,000 to 25,000 genes present in a normal genome. Every gene present in the human body is responsible for a specific function. Subsequently, any undesired alteration in these genes may lead to the disease. Many diseases like cancer, arthritis, color-blindness, sickle cell anemia, etc, are mainly caused as a result of gene variation.

About the Technique.

This technique provides a genetic level treatment to an individual. It serves its action by manipulating the gene expression, which thereby alters the natural characteristics of living cells to cure the disease.

Mechanism of action.

This therapeutic mechanism has become important to study and treat many genetic, infectious diseases including cancer. Gene therapy utilizes several contrivances to accomplish its task:

By inactivating the damaged or disease-causing gene from the cellular constituents.
By introducing a novel gene playing an efficient role in the treatment of disease.
By replacing a destructive gene with a healthy one.

Currently, the biological products required for the implementation of this technique are regulated by the Center for Biologics Evaluation and Research (CBER) along with their marketing requiring submission and consent of the biologics license application (BLA).

Several approaches.

Some of the important approaches of gene therapy are undertrial of various scientists that are mentioned as follows:

Insertion of the artificial gene with improved functioning into the human body.
Introduction of healthy gene with replacement of defected one.
Application of the “Knock-out” method in the selection of damaged genes from the genome.

Undoubtedly gene therapy is an apt and auspicious treatment option for many diseases comprising certain types of carcinomas, viral infections, and inherited disorders. But it remains at risk and is statically understudy over a long period thereby, considering it less reliable to be used for Convinence. Moreover, this practice is presently being tested only for few fully Uncurable diseases summarizing the advancement and prospects for a better future and easy treatment of all the diseases.
