Recently, scientists from the MDI biological laboratory, research Institute of aging Tank, and the University of Nanjing shocked the medical world by announcing that they were able to extend lifespan in worms-the nematode Caenorhabditis elegans at 500%. The worms C. elegans are often used in studies of aging. Despite the fact that biologically they are far from human, these organisms share many genetic paths with people. As they say in their work, scientists, nature does not waste main mechanisms of protection of cells. Instead, similar biological pathways again and again occur in many organisms and some of them develop into more advanced and complex animals. A study published in the journal Cell Reports.
How are worms and people?
Worms Caenorhabditis elegans live only 2-3 weeks, and their body is designed to a disgrace simply. These qualities make them ideal subjects for a genetic studies, especially in the field of aging. The fact that to see the result of the worms C. elegans can be directly. Anyway, this is another indication that aging is the cumulative work of several genetic programs. Today, researchers agree on the fact that there is no separate “gene of longevity”, because aging is the result of joint work of the genes for a long time.
The increased longevity of the worms-nematodes, however, does not mean that we are going to live 400 years. At the same time, the work is stunning in itself. As the researchers write, nothing in nature does not exist in a vacuum. To develop the most effective anti-aging treatments, need to pay attention for “networks of longevity,” not on specific paths. The fact that the main problems with aging is the development of diseases such as cancer, Alzheimer’s and Parkinson’s, diabetes, arthritis, cardiovascular disease, etc. These diseases today can be prevented or significantly improve the health status of patients due to the genetic manipulations and various medications.
As writes the edition Forbes, in the opinion of the authors of the study, the scientists approaching the moment when they will be able to understand what actions or medications are the most effective ways to combat age-related changes.
