The polymer molecule is packaged within a " vector ", which carries the molecule inside cells. ... Officially, their study was a failure, for their experiment did not show what the researchers hoped it would. The main aim of gene therapy is to cure a disease by providing the patient with a correct copy of the defective gene… 'It is important to make these reports promptly so that appropriate measures can be taken by other researchers to safeguard the health of their patients', an NIH official said. Keywords:gene therapy, stem cell, regeneration, chronic renal failure… Gene therapy has some potential risks. Hundreds of failed gene therapy experiments, including a number of deaths, have been revealed in the US. Title: Stem Cell Gene Therapy for Chronic Renal Failure VOLUME: 3 ISSUE: 5 Author(s):T. Yokoo, K. Sakurai, T. Ohashi and T. Kawamura Affiliation:Division of Nephrology and Hypertension, Department of Internal Medicine, Jikei University School ofMedicine, 3-25-8 Nishi-Shimbashi, Minato-ku, Tokyo, Japan 105-8461. 'Because of the commercialisation of this research there really is an incentive to keep secret anything that reflects badly on the progress of the work', said Professor Stuart Newman of the New York Medical College. … … Many viruses can insert their genes into the DNA of their hosts. In it, a group of researchers led by Patrick Yu-Wai-Man, an ophthalmologist at Cambridge University, investigated a promising new genetic therapy for a hereditary form of blindness. Gene therapy is a medical therapeutic process involving the delivery of the gene into cells to treat diseases. Doctors think gene therapy could be a solution. Rather, it usually has to be delivered using a carrier, called a vector.The most common gene therapy vectors are viruses because they can recognize certain cells and carry genetic material into the cells' genes. A story of gene therapy and happy accidents. Jesse Gelsinger (June 18, 1981 – September 17, 1999) was the first person publicly identified as having died in a clinical trial for gene therapy. Although the exact cause of her death is still unknown, the usually mild fungal infection found throughout Mrs Mohr's body... Two US institutions that ran a gene therapy trial in which a teenager died in 1999 agreed to pay more than $1 million in a civil settlement last week. In recent years, research on it has increased considerably. Gene therapy for the heart is one of the most relevant advances in medicine today, providing a new treatment strategy for heart failure. Gene therapy remains an obvious route to treat OTC. Researchers remove the original disease-causing genes from the viruses, replacing them with the genes needed to stop disease.This technique presents the following risks: 1. The Food and Drug Administration ordered Schering-Plough Corp. to temporarily halt new enrollments in two gene therapy studies last week after a teen-ager in a similar experiment died Sept. 16. Since most cases are caused by a mutation in a single gene, LHON is a good candidate for gene therapy, a form of genetic engineering which aims to replace the defective gene with a working one. Hundreds of failed genetic therapy experiments, including a number of deaths, came to light in the US this week. On the face of it, that was bizarre. Over the last few years, novel … Using two eyes in the same patient makes for a perfect control: their genetic make-up is identical, and any confounding lifestyle factors are removed from the equation. The disease in question is Leber hereditary optic neuropathy (LHON). But it was also a smashing success, for 29 of the 37 participants reported big improvements in their vision. Instead, in more than three-quarters of their patients, they saw substantial improvements in both eyes. They did not, and for that reason the study failed in its primary objective. It affects between one in 30,000 and one in 50,000 people. Representatives of the Food and Drug Administration (FDA) and the NIH told a senate hearing last week that they have no explanation for the late reports. Tissue and fluid samples from monkeys given the same treatment as the human patients showed viral DNA in both eyes, not just one. … A failed study shows a promising treatment for blindness, Sound engineers have better ways to trick listeners’ ears, Wheat absorbs phosphorus from desert dust, Fascinating science stories overlooked this year. Despite early failures, gene therapy trials for various diseases, most notably inherited blindness (whereby gene transfer by AAV vectors partially restored vision in a pediatric patient with Leber congenital amaurocis, a major cause of congenital blindness131), cancer, infectious diseases, monogenic diseases, and cardiovascular diseases are underway.
