Treatment of cancer-cachexia rats with formoterol significantly attenuated the decrease in MyHC-I and MyHC-II isoforms, and total MyHC protein content, while it did not modify the content of the other study muscle proteins (Figs. 4A–4C, 5A–5C and Figs. S9–S13, respectively). The gene discussed is MYH6; the disease is Cachexia.
