Long Live Living

Long Live Living Scientists are testing the possible action of reversing the senescent process, not just looks, but also the internal health such as organ health. In an obligate post in Medical News, French researchers have man hop ond to narrow grey cells into any and all kinds of cells. They are able to reprogram, in a sense, adult cells back into embryonic cells. But forwards the scientists nifty success, reprogramming the cells had a limit, called senescence, or simply put, cells that reach their age limit, foreswear dividing, and die. The reason the cells reached a state of senescence was because of desoxyribonucleic acid units, cognize as telomeres, which acted like the plastic caps at the ends of a shoelace, preventing the chromosomes from fraying and the genes inner(a) them from unraveling. (3) Ronald A. DePinho, M.D., president of The University of Texas MD Anderson Cancer Center in Houston began a study in which reactivating telomerase in mice might actuall y splitor possibly reversethe shortening of telomeres, and thus distort back the clock on some aspects of aging. Thus Dr. DePinho uprise a team that made genetically engineered mice that aged prematurely. The animals had short, nonadaptive telomeres and suffered a range of age-related problems. Their spleens were atrophied, their intestines were damaged, and the sense of smell was impaired. The researchers had devised an estrogen-based drug that would free on the animals dormant telomerase gene, known as TERT. The drug, in the soundbox of a time-release pellet, was inserted under the skin of some mice. A supply pellet without the active drug was given to a severalise group of control mice. (3) A month later, the treated mice showed affect signs of rejuvenation. Overall, their telomeres had lengthened and the levels of telomerase had increased. This woke up the dormant brain stem cells, producing invigorated neurons. The spleen, testes and brain grew in size. (3) One worry is cancer. Tumors somehow exalta! tion on the telomerase gene, allowing...If you want to get a full essay, line of battle it on our website: BestEssayCheap.com
