TRIM63 and neoplasm: Besides that, to explore whether muscle wasting was specific in GA muscles or it was a more generalized process, we examined the mRNA levels of MAFbx and MURF1 in other muscle types including tibialis anterior (TA), quadriceps, soleus and cardiac muscles, and found that MAFbx and MURF1 expression was consistently elevated in all of these muscles when compared YES2‐bearing mice with non‐tumour‐bearing mice (Fig. S1E).
