Talking About Application Of Genetic Engineering In Medicine

Genetic engineering means that the DNA of different organisms is digested and connected in vitro to form arecombinant DNA molecule, and then transferred into the recipient cell, so thatthe exogenous gene is expressed in the recipient cell. The application ofgenetic engineering in medicine has been very extensive, and the applicationfield has been continuously expanded, and surprising achievements have beenmade.

Genetically engineered pharmaceuticals

The application of geneticengineering in medicine has opened up a new era in the pharmaceutical industryand solved the problem of drugs that could not be produced or economicallyproduced in the past. Now, human beings have been able to produce a largenumber of cheap and high-quality new drugs and diagnostic reagents throughgenetic engineering, such as human growth hormone, human insulin, urokinase,erythropoietin, interleukin, interferon, and colony-stimulating factor. ,epidermal growth factor, etc. It is exciting that the advent of drugs withhighly specific and targeted genetically engineered protein peptides has notonly changed the product structure of the pharmaceutical industry, but alsoprovided effective drugs for the treatment of various diseases such asdiabetes, kidney failure, cancer, dwarfism and so on.

Genetically engineered antiviralvaccines

Genetically engineered hepatitis Bvaccine, rabies vaccine, epidemic hemorrhagic fever virus vaccine, rotavirusvaccine, etc. have been used in clinical practice to improve human resistanceto various viral diseases. For example, the advent of the hepatitis B virusvaccine, so that our newborns will no longer be attacked by the hepatitis Bvirus, and also reduce the incidence of liver cancer in the population. Humanshave also produced vaccines against various germs, schistosomiasis, andprotozoa through genetic engineering to improve the body's immunity to variousinfectious diseases. The advent of deoxyribonucleic acid or genetic vaccines hastransformed the body's immune system. The development of application of geneticengineering in medicine has overcome the instability of monoclonal antibodyproduction cell lines in the production process, and provided an advancedproduction process for the production of a large number of highly effectiveantiviral vaccines.

Genetic engineering to treatdiseases

Clinical practice has shown thatthe application of genetic engineering in medicine has transformed the entirefield of prevention and treatment of medicine. The meticulously designedgenetic engineering operation by humans has overcome the immune rejectioncaused by organ transplantation between different individuals and even species,and the transplantation between human beings has been successful. Successfulsolid organ transplantation includes kidney, heart, liver, pancreas, Lungs,intestines, and dual-organ and multi-organ combined transplants. And organtransplantation between humans and animals has become a reality, and clinicalapplication is just around the corner. The perfection and automation of thechemical synthesis of deoxyribonucleic acid and the optimization of thedeoxyribonucleic acid amplification technology to synthesize gene"probes" and improve the quality of clinical diagnosis are what humanbeings are eagerly looking forward to. There are two ways of gene therapy, oneis gene therapy of somatic cells, and the other is gene therapy of germ cells.Gene therapy of somatic cells is to introduce normal genetic genes into thefertilized egg cells, so that this genetic material enters the genome of thefertilized egg, and as the fertilized egg divides, it is distributed to eachdaughter cell, and finally corrects the future individual. genetic defect. Thegene therapy of germ cells is to introduce the "target gene" designedby humans into the germ cells of patients with genetic diseases. The operationtechnique of this method is extremely complicated, and it involves ethics.

Genetic engineering diagnosis

Using genetic methods to diagnose diseasesand find the root cause of diseases from genes, aims to eradicate hereditarydiseases and find new diagnostic channels for "incurable diseases"such as cancer, AIDS, and idiots. At present, the gene diagnosis technology ofpolymerase chain reaction is the latest technology to diagnose human diseasesat the gene level. In principle, as long as doctors have the appropriate tool"probes", they can correctly diagnose any genetic disease, regardlessof whether the disease gene produces the corresponding protein. This method ofdiagnosis is not limited to the diagnosis of cancer, but also used for prenataldiagnosis and presymptomatic diagnosis. Genetic engineering is the greatestachievement in the field of life sciences in the 20th century, opening up a newera of life sciences. The application of genetic engineering in medicine is notonly extensive, but also advanced. It provides products with continuous andhigh practical value for the well-being of human beings, health and longevity,and the development prospect is extremely broad.

The application of geneticengineering in medicine makes human medical research into a new stage,scientists in the development of new drugs, the diagnosis of common diseasesand the exploration of new therapeutics and other aspects have achievedfruitful results. In the process of the research and utilization of geneticengineering, we must adhere to the scientific attitude of dialecticalmaterialism, make full use of the advantages and circumvent the disadvantages,so that genetic engineering can ultimately benefit mankind!
