Caption: This is a fatty liver with SIRT7. The microscope images show the liver tissue of control animals (left) and mice that lack the SIRT7 gene magnified by a factor of 400. Whereas the control animals form large numbers of fat depots when fed a high-fat diet, the SIRT7-knockout mice do not develop fatty liver.
