The impact of biotechnology development on medicine

Date of release:2018-06-23 Author: Click:

        Biotechnology is a technology that utilizes the basic principles of applied biology, chemistry and engineering to produce useful substances or to provide services to humans by using organisms (including microorganisms, animal cells and plant cells) or their components (organelles and enzymes). In recent years, with the rapid development of modern biotechnology, including the achievements of genetic engineering, cell engineering, protein engineering, enzyme engineering and biochemical engineering, chemical products are produced by utilizing the characteristics of biotransformation, especially new products that are difficult to be obtained by general chemical means, so as to change the existing technology and solve the long-term problems. The energy crisis and environmental pollution, which have been puzzled for a long time, have attracted more and more attention and have been put into practice. Ji'nan cell engineering

        In the first year of twenty-first Century, scientists completed the sequencing of human genes. The impact of this achievement on the development of biotechnology industry is immeasurable. In exploring the mysterious process of human genes, discovering some new drugs has become a focus of biotechnology.(Living cells

In May 2001, the FDA approved the launch of Gleevec, a good drug for chronic leukemia, developed by Novartis. This is the first anticancer drug designed and developed on the basis of the mechanism of cancer cell activity. Traditional anticancer drugs can affect normal cells during treatment, and have a great side effect on patients. Gleevec only kills mutated cancer cells. Recent studies have shown that Gleevec is effective against both blood cancers and tumors, and may become a new broad-spectrum anticancer drug.

Another biotechnological drug for cancer is monoclonal antibody. The targets of these antibodies are related to some specific molecules of cancer cells. Since 1980, the magic effect of monoclonal antibodies has attracted the attention of many pharmaceutical companies. After more than 10 years of research, monoclonal antibody as a new anticancer drug has been initially realized. At present, many pharmaceutical factories are developing monoclonal antibodies. Their applications have expanded from anti-cancer to treatment of other diseases. By 2000, the FDA approved nine monoclonal antibodies, and more than 60 other products are in clinical trials.

In anti-cancer, the role of monoclonal antibodies as the human body's autoimmune system, but in most cases, the human body's autoimmune system will not be cancer cells as harmful cells to stop, so that cancer cells in the body to multiply, endangering human life.

The role of monoclonal antibodies is to target cancer cells, kill or activate the immune system in vivo to attack cancer cells. Monoclonal antibodies can also be a "smart bomb" that carries radioactive or chemical agents to attack cancer cells.
