Surrounding the Breast Cancer Genes The process of unraveling the mysteries of the human genome creates enormous possibilities in the world of science. Knowing where on our chromosomes a specific gene lies allows scientists to look inside the human body with more intensity than any X-ray could ever achieve. By analyzing the genetic make-up of human beings, scientists can track diseases back to their most fundamental stages. In recent years, scientists have discovered two genes that play a role in

Cancer occurrs by the production of multiple mutations in a single cell that causes it to proliferate out of control. Cancer cells often different from their normal neighbors by a host of specific phenotypic changes, such as rapid division rate, invasion of new cellular territories, high metabolic rate, and altered shape. Some of those mutations may be transmitted from the parents through the germ line. Others arise de novo in the somatic cell lineage of a particular cell. Cancer-promoting mutations

Gene Therapy and Cancer In 1997, an estimated 1.38 million Americans will be newly diagnosed with cancer (Blaese, 1997). The treatments available only cure half of them. Many new strategies, including gene therapy are in developmental stages for treating cancer. Nearly half of all gene therapy trials currently under way deal with cancer and experts believe a number of these applications will be in use within the next three to five years (Lyon, 1997). Cancer is considered a genetic disorder

Gene therapy is a relatively new discovery in the world of science. For years, doctors and researchers have been developing biological tools that are used in gene altering today. However, in recent years, doctors have begun to investigate the possibility of healing diseases through the process of gene therapy. Gene therapy is an experimental medical process that through which, doctors seeks to strengthen the body by replacing missing and damaged genes. Some people believe that replacing the

Gene 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 cells

Cancer Treatment With Gene Therapy Gene therapy has been progressing over the past half-century and has led to many discoveries pertaining to the treatment of cancer. Normal body cells can either become cancerous by losing or gaining a function. To treat cancer, scientists can either replace damaged genes (such as a damaged tumor suppressing gene) in the malignant cells or stop the cells from overexpressing genes (such as oncogenes, or genes that have been altered and can cause the development of

Cancer and Gene Therapy Gene therapy is an experimental technique that allows doctors to insert a gene into a patient’s cell rather than using drugs or surgery. Gene therapy is a process of which defective or undesired genes in the body with “normal” genes. A vector is re-engineered to deliver the gene to a target cell. Then the gene is transferred to the cell’s nucleus and must be activated in order to function. The main focus of gene therapy is to replace a lost or improper gene with a new functional

Breast cancer is the most common cancer that affects women in the United States. There are at least two majors genes (BRCA1 and BRCA2) that when they mutate can cause breast cancer. These genes can be passed from parent to child, increasing the risk of developing cancer in those child that have parent carrying these genes. BRCA1 and BRCA2 genes are located on chromosome 17 and chromosome 13 respectively. There is a 90% chance of developing breast cancer for a woman that has these mutated genes. In contrast

Cancer is perhaps one of the most irksome diseases whose causes are often elusive and unrecognizable. The etiological agents of cancer are difficult to estimate and it is not attributed to purely genetic or purely environmental factors, and therefore, cancer research has been largely focused on the interaction between genes and the environment (Mucci et al., 2001). A large number of studies have investigated the possible causes of various types of cancers, implicating diet, heredity and environment

Genetics Research Paper The Mutation of the p53 Gene and Its Impact on Lung Cancer Cancer occurs when new cells are born to replace old cells but the old cells do not undergo apoptosis, as they normally should. Instead, the new cells come together to form tumors that can potentially become malignant, meaning they have the ability to chew through the basal lamina and enter the bloodstream to spread to new environments throughout the body. Cancer could also occur due to cell overproliferation because
