Mice with hyperactive Wnt10b gene eat all they want, but have half the body fat of normal mice
...experimental mice. Wnt10b is one of a family of 19 related proteins. Wnts (pronounced "wints") regulate the complex changes that take place as an embryo grows. Part of this process is the development of fatty adipose tissue, which contains fat cells called adipocytes. Ormond A.
