However, its function(s) in osteoclasts, cells that slowly breakdown bone (a process known as resorption), has not been determined. In addressing this issue, Sakae Tanaka and colleagues, at The University of Tokyo, Japan, have discovered that not only does Bcl-xL prevent osteoclast apoptosis in mice, it also negatively regulates the bone-resorbing activity of osteoclasts. http://phys.org/news172168808.html Medicine & Health Mon, 14 Sep 2009 18:30:01 EST news172168808
