In a model of C26 colon carcinoma‐bearing mice, the administration of IL‐4 (1.3 μg per mouse, every day) improved cachexia, as shown by increased muscle mass, fibre CSA, and SC pool.S39 Moreover, in a mouse muscle atrophy model, the combined administration of HGF and LIF6 significantly increased the weight of the TA (9%), extensor digitorum longus (EDL) (18%), and CSA of EDL (22%).52 Here, IL4 is linked to colon carcinoma.
