MSTN and cancer: This series of experiments aimed to evaluate the effects of anti-GDF-15 antibody treatment in combination with muscle anabolic (anti-myostatin antibody) or appetite stimulant (ghrelin receptor agonist anamorelin) modulators using mouse cancer cachexia models.<h4>Methods</h4>The effects of anti-GDF-15 monoclonal antibody alone and in combination with an anti-myostatin antibody or anamorelin fumarate were examined in GDF-15-dependent (HT-1080 and RENCA) and partially dependent (TOV21G) mouse tumour models.
