Using reverse transcription–quantitative polymerase chain reaction (RT‐qPCR), we first confirmed that FoxP1 is increased in skeletal muscle of cachectic mice bearing C26 tumours, and further established that FoxP1 is elevated in several additional mouse models of cancer cachexia, including the subcutaneous LLC and L3.6pl models, as well as in the orthotopic L3.6pl model of pancreatic cancer cachexia (Figure1A). This evidence concerns the gene FOXP1 and familial pancreatic carcinoma.
