found that the ratio of gene expression levels of pro‐apoptotic Bax to anti‐apoptotic Bcl‐2 is elevated in skeletal muscle of rats with hepatocellular carcinoma and that IL‐15 administration attenuates this increase, suggesting that IL‐15 inhibits tumour‐mediated apoptosis in skeletal muscle fibres.8 The gene discussed is IL15; the disease is hepatocellular carcinoma.
