A University at Buffalo-led analysis crew has proven that a protein named for the legendary land of youth in Irish folklore is efficient at reversing aging in skeletal muscle cells.
Published Sept. 3 in Science Advances, the examine facilities on the protein NANOG, which is derived from Tír na nÓg, a spot in Irish lore famend for eternal youth, health and beauty.
In a sequence of experiments, researchers overexpressed NANOG in myoblasts, that are the embryonic precursors to muscle tissue. The myoblasts have been senescent, which means they have been now not in a position to divide and develop.
The overexpression ameliorated some of the first traits related to age-related deterioration of cells, together with autophagy, power homeostasis, genomic stability, nuclear integrity and mitochondrial perform.
Most notably, NANOG elevated the quantity of muscle stem cells within the muscle of prematurely aging mice. This demonstrated the feasibility of reversing mobile aging within the physique with out the necessity to reprogram cells to an embryonic pluripotent state, a course of that’s usually utilized in stem cell remedy however runs the chance of tumorigenesis.
“Our work focuses on understanding the mechanisms of NANOG’s actions in hopes of discovering druggable targets in signaling or metabolic networks that mimic the anti-aging effects of NANOG. Ultimately, the work could help lead to new treatments or therapies that help reverse cellular senescence, and aid the many people suffering from age-related disorders,” says the examine’s corresponding writer Stelios T. Andreadis, PhD, SUNY Distinguished Professor within the Department of Chemical and Biological Engineering on the UB School of Engineering and Applied Sciences.
