Eldorado Posted February 11, 2021 #1 Share Posted February 11, 2021 Researchers from the UCLA School of Dentistry have identified the role a critical enzyme plays in skeletal aging and bone loss, putting them one step closer to understanding the complex biological mechanisms that lead to osteoporosis, the bone disease that afflicts some 200 million people worldwide. The findings from their study in mice, published online today in the journal Cell Stem Cell, could hold an important key to developing more effective treatments for osteoporosis and improving the lives of an aging population, they say. Cells in the bone marrow known as mesenchymal stem cells serve as the building blocks of the body’s skeletal tissues, but whether these stem cells ultimately develop into bone or fat tissues is controlled in part by what are known as epigenetic factors — molecules that regulate genes, silencing some and activating others.
