Recently, scientists have discovered that there is a type of cell that are called senescent cells, and are bad cells that participate in the aging of the tissues. Scientists are trying to determine if there is a drug that will be able to stop these cells so that people will age less and the tissue will be able to continue being healthy. Seeing if the drug will make people live longer is something that must be tested and is highly unlikely. In order to continue out some of the experiments a research team led by Darren J. Baker and Jan M. van Deursen at the Mayo Clinic in Rochester, Minn., has generated a strain of mouse in which all the senescent cells can be purged by giving the mice a drug that forces the cells to self-destruct. Researchers reported online Wednesday in the journal Nature, the mice’s tissues showed a major improvement in the usual burden of age-related disorders. They did not develop cataracts, avoided the usual wasting of muscle with age, and could exercise much longer on a mouse treadmill. They retained the fat layers in the skin that usually thin out with age and, in people, cause wrinkling.
I thought that this article could have improved by first letting us know the mice’s condition with aging. Learning more about the mice’s precondition would’ve helped me get a better perspective of how the mice respond to the tests. I also would’ve liked to have more information on the drug that is being tested to help with the aging tissue. I think that if we were able to know what effects the drug have and how long the process usually takes. Unfortunately the facts aren’t available to readers due to the fact that tests have not yet been completed.
I overall thought that this article was extremely interesting. I thought that it was an awesome fact that scientists are working on preventing old age and keeping aging tissues. I also thought that the results of the mice was a remarkable discovery and I look forward to hearing about what effects this drug will have on people themselves.
One of the aspects that I liked that Grace did summarizing this article was that she really focused on the main points in the article which really helped me understand this article. The summary was very easy to read and easy to understand because she organized the article very well. She also gave good specific details of the whole article.
ReplyDeleteThere were some things that Grace could have done to improve this article summary like that she should have gave some background information of this cell. She also should have been more specific in the details of the article like including some examples to help me understand about the cell and experiments.
I was very impressed that the scientists have found out this cell that harms our tissues. It’s very interesting that if the scientists find a way to stop to this cell to produce, people would then live longer.
