Biotechnology in Medicine and Agriculture

Biotechnology in Medicine and Agriculture Biotechnology in Medicine and Agriculture Bởi: OpenStaxCollege It is easy to see how biotechnology can be used for medicinal purposes Knowledge of the genetic makeup of our species, the genetic basis of heritable diseases, and the invention of technology to manipulate and fix mutant genes provides methods to treat diseases Biotechnology in agriculture can enhance resistance to disease, pests, and environmental stress to improve both crop yield and quality Genetic Diagnosis and Gene Therapy The process of testing for suspected genetic defects before administering treatment is called genetic diagnosis by genetic testing In some cases in which a genetic disease is present in an individual’s family, family members may be advised to undergo genetic testing For example, mutations in the BRCA genes may increase the likelihood of developing breast and ovarian cancers in women and some other cancers in women and men A woman with breast cancer can be screened for these mutations If one of the high-risk mutations is found, her female relatives may also wish to be screened for that particular mutation, or simply be more vigilant for the occurrence of cancers Genetic testing is also offered for fetuses (or embryos with in vitro fertilization) to determine the presence or absence of disease-causing genes in families with specific debilitating diseases Concept in Action See how human DNA is extracted for uses such as genetic testing 1/6 Biotechnology in Medicine and Agriculture Gene therapy is a genetic engineering technique that may one day be used to cure certain genetic diseases In its simplest form, it involves the introduction of a non-mutated gene at a random location in the genome to cure a disease by replacing a protein that may be absent in these individuals because of a genetic mutation The non-mutated gene is usually introduced into diseased cells as part of a vector transmitted by a virus, such as an adenovirus, that can infect the host cell and deliver the foreign DNA into the genome of the targeted cell ([link]) To date, gene therapies have been primarily experimental procedures in humans A few of these experimental treatments have been successful, but the methods may be important in the future as the factors limiting its success are resolved This diagram shows the steps involved in curing disease with gene therapy using an adenovirus vector (credit: modification of work by NIH) Production of Vaccines, Antibiotics, and Hormones Traditional vaccination strategies use weakened or inactive forms of microorganisms or viruses to stimulate the immune system Modern techniques use specific genes of microorganisms cloned into vectors and mass-produced in bacteria to make large quantities of specific substances to stimulate the immune system The substance is then used as a vaccine In some cases, such as the H1N1 flu vaccine, genes cloned from the virus have been used to combat the constantly changing strains of this virus Antibiotics kill bacteria and are naturally produced by microorganisms such as fungi; penicillin is perhaps the most well-known example Antibiotics are produced on a large scale by cultivating and manipulating fungal cells The fungal cells have typically been genetically modified to improve the yields of the antibiotic compound 2/6 Biotechnology in Medicine and Agriculture Recombinant DNA technology was used to produce large-scale quantities of the human hormone insulin in E coli as early as 1978 Previously, it was only possible to treat diabetes with pig insulin, which caused allergic reactions in many humans because of differences in the insulin molecule In addition, human growth hormone (HGH) is used to treat growth disorders in children The HGH gene was cloned from a cDNA (complementary DNA) library and inserted into E coli cells by cloning it into a bacterial vector Transgenic Animals Although several recombinant proteins used in medicine are successfully produced in bacteria, some proteins need a eukaryotic animal host for proper processing For this reason, genes have been cloned and expressed in animals such as sheep, goats, chickens, and mice Animals that have been modified to express recombinant DNA are called transgenic animals ([link]) It can be seen that two of these mice are transgenic because they have a gene that causes them to fluoresce under a UV light The non-transgenic mouse does not have the gene that causes fluorescence (credit: Ingrid Moen et al.) Several human proteins are expressed in the milk of transgenic sheep and goats In one commercial example, the FDA has approved a blood anticoagulant protein that is produced in the milk of transgenic goats for use in humans Mice have been used extensively for expressing and studying the effects of recombinant genes and mutations Transgenic Plants Manipulating the DNA of plants (creating genetically modified organisms, or GMOs) has helped to create desirable traits such as disease resistance, ...MOLECULAR CLONING – SELECTED APPLICATIONS IN MEDICINE AND BIOLOGY Edited by Gregory G.

The NATO SPS Programme supports meetings in the following Key Priority areas: (1) Defence Against Terrorism; (2) Countering other Threats to Security and (3) NATO, Partner and Mediter- ranean Dialogue Country Priorities. The types of meeting supported are generally "Advanced Study Institutes" and "Advanced Research Workshops". The NATO SPS Series collects together the results of these meetings. The meetings are coorganized by scientists from NATO countries and scientists from NATO's "Partner" or "Mediterranean Dialogue" countries. The observations and recommendations made at the meetings, as well as the contents of the volumes in the Series, refl ect those of participants and contributors only; they should not necessarily be regarded as refl ecting NATO views or policy. Advanced Study Institutes (ASI) are high-level tutorial courses intended to convey the latest developments in a subject to an advanced-level audience Advanced Research Workshops (ARW) are expert meetings where an intense but informal exchange of views at the frontiers of a subject aims at identifying directions for future action Following a transformation of the programme in 2006 the Series has been re-named and re-organised. Recent volumes on topics not related to security, which result from meetings supported under the programme earlier, may be found in the NATO Science Series. The Series is published by IOS Press, Amsterdam, and Springer, Dordrecht, in conjunction with the NATO Public Diplomacy Division. Sub-Series A. Chemistry and Biology Springer B.
