Abstract:Cachexia, progressive loss of fat and muscle mass despite adequate nutrition, is a devastating complication of cancer associated with poor quality of life and increased mortality. Myostatin is a potent tonic muscle growth inhibitor. We tested how myostatin inhibition might influence cancer cachexia using genetic and pharmacological approaches in mice. First, myostatin null mice were challenged with Lewis lung carcinoma or B16F10 melanoma. Although hypermuscular at baseline, myostatin null mice were more sensit… Show more
