FBXO32 and cancer: To confirm that muscles from these cancer‐bearing mice had atrophy typical of cachexia, we used quantitative real‐time polymerase chain reaction (qPCR) to analyse the muscle mRNA expression of Fbxo32/atrogin 1 and MuRF1, the main ubiquitin ligases involved in protein degradation during cancer‐mediated muscle atrophy.13
