TRAF6 and myeloid sarcoma: When we reviewed the effect of muscle mass, we observed that proteasomal gene expression was reduced in myotubes incubated with sera from severely sarcopenic HNC patients, as found for TCM (Murf 1 = 0.31 ± 0.26 for SS vs. 0.80 ± 0.43 for MS, p < 0.001; MafBx = 0.81 ± 0.14 for SS vs. 0.68 ± 0.03 for MS, p = 0.02; TRAF6 = 0.85 ± 0.19 for SS vs. 1.12 ± 0.24 for MS, p = 0.01; Fox O = 0.79 ± 0.17 for SS vs. 1.18 ± 0.25 for MS, p < 0.001 (Figure 6)).
