The miracle has happened at last – scientists have found a way to prevent aging. A group of American scientists from the University of Case Western Reserve claim that a group of proteins called KLFs, which is present in worms and mammals, as well as humans, regulates gene activity and its concentration can affect aging. The molecular mechanism responsible for the life span of worms and mammals is determined by a certain group of proteins, according to a new report published by scientists from the University of Case Western Reserve, published in the journal Nature Communications. In the course of the study, experts found that increasing or decreasing the concentration of Kruppel-like factors (KLFs) regulating gene activity allows for the prolonging or shortening of the life of Caenorhabditis elegans nematodes. It is noted that the KLF protein is present not only in worms, but also in mammals, including humans. These compounds inhibit gene expression, during which DNA information is used
