Noteworthy, muscles of pre-cachectic and cachectic cancer patients showed ~3-fold increase (p < 0.05) in RAGE amounts and reduced Akt-GSK-3β-PGC-1α pathway, compared with healthy control subjects.<h4>Conclusions</h4>Our data provide evidence that RAGE engagement at myofibre level drives loss of body and muscle weights and inflammation in cancer conditions. Here, GSK3B is linked to cancer.
