Similar to cachectic C26 mice, cachectic LLC tumour‐bearing mice had higher levels of plasma PAF‐AH activity than control PBS‐injected mice (Figures1N and S1N and Morigny et al. 19), and the circulating activity was also closely associated with loss of body weight, white adipose tissue, and skeletal muscle mass (Figures1O and S3A–S3C). The gene discussed is PLA2G7; the disease is neoplasm.
