Genetic Engineering And Immunotherapy Of Cancer - 1394 Words

Genetic Engineering and Immunotherapy of Cancer Genetic engineering is a highly controversial but incredibly powerful and significant branch of biotechnology that will heavily impact the future of human life, if we choose to utilize it. Humans have utilized the engineering of life for thousands of years through selective breeding, which has strengthened the traits in plants and animals that are helpful to humans. Even though we as a species have employed this for ages, it was not until recently that the specific mechanisms were discovered and studied. Once Deoxyribonucleic Acid (DNA)* was discovered as the molecule that acts as the blueprint for all living organisms, researchers have been searching for ways to alter it. In the 1960s,†¦show more content†¦Cells also contain a gene called Proto-Oncogenes*, which does the exact opposite as TSG when activated and turned into Oncogenes. How and when these genes are switched on and off determine the cell’s growth, and ultimately the development of cancer. If the TSG is s witched off, this can cause problems. Furthermore if the Oncogenes are activated, the cells can become antisocial and ignore the tissue growth regulation mechanisms and begin to proliferate uncontrollably. When this happens, it usually forms a tumor*. This structure then continues to grow and mutate, since many regulatory genes and their promoters have been damaged or changed. The tumor is now even more vulnerable to mutation. This can then deactivate DNA repair genes, causing further problems and susceptibility. Cancerous cells that reach tumor status are able to because they are not recognized by T-Cells* of the immune system. T-Cells are critical for removing harmful or infected cells from the body. T-Cell protein receptors bind to foreign protein receptors expressed on harmful cells to identify the dangerous cells. After identification, the T-Cell destroys the harmful cell. However, since T-Cells can only identify â€Å"non-self† cells, they are often unable to target the cancerous cells that are â€Å"self†. This allows most cancers to escape detection by T-Cells and proliferate. However, if human T-Cells were made to be able to detect andShow MoreRelatedHuman Genetic Engineering : Is It Good?1242 Words   |  5 PagesHuman Genetic Engineering: Is It Good? Ciabhan Moore Bellevue Big Picture Student s-moorec@bsd405.org Abstract – Human Genetic Engineering has always been an idea to enhance humans, whether that is to remove life-threatening diseases or give humans different abilities. To accomplish these tasks at hand, one needs to know the science behind what it takes to modify a human and both the positive and negative effects To know how Human Genetic Engineering works, one needs to know specific topics suchRead MoreBenefits of Immunotherapy from Advances in Immunology and Recombinant Dna Technology3196 Words   |  13 PagesBenefits of Immunotherapy from advances in immunology and recombinant DNA technology. Immunotherapy is a form of medical treatment intended to stimulate or restore the ability of the immune system to fight infection and disease. This can be by inducing, enhancing, or suppressing an immune response. Immunotherapies designed to elicit or amplify an immune response are classified as activation immunotherapies, while those that reduce or suppress immune response are suppression immunotherapies. ActiveRead MoreGenetic Engineering Essay1556 Words   |  7 PagesGenetic Engineering Genetic engineering is the alteration of genetic code by artificial means, and is therefore different from traditional selective breeding. Genetic engineering (GE) is used to take genes and segments of DNA from one species, e.g. fish, and put them into another species, e.g. tomato. To do so, GE provides a set of techniques to cut DNA either randomly or at a number of specific sites. Once isolated one can study the different segments of DNA, multiplyRead MoreCauses And Treatment Of Pancreatic Cancer1385 Words   |  6 PagesINTRODUCTION Pancreatic cancer is the fourth leading cause of cancer death Worldwide. It is the eighth most common cause of death from cancer in both individuals. Higher incidence is noted as thirteen because of the very poor prognosis. Less than 5% of all patients are still alive only for 5 years after initial diagnosis. It is rarely detected in the early stages and conventional cancer treatment failed due to high resistance to chemotherapy. Pancreatic cancer develops gradually in a series of stepsRead MoreEssay on Gene Therapy and Its Effect on Cancer3614 Words   |  15 PagesGene Therapy and Its Effect on Cancer The era of scientific advancement in the twentieth century has encouraged several scientific fields to merge into a new, futuristic science called Biotechnology. One idea behind Biotechnical science is taking advantage of molecular biology. At the forefront of this advancement is gene therapy which attempts to treat disease at its origin on the molecular level(Kreeger,1996). Essentially, this therapy deliberately introduces genes into the human cellsRead MoreGsk Annual Report 2010135604 Words   |  543 Pagesincreased value for shareholders of 2012, we expect phase III data on around 15 assets, including as well as deliver better outcomes to patients and consumers. potential new treatments for type 1 and 2 diabetes, several rare diseases and multiple cancer types.
