Proteolysis-inducing factor is expressed in tumours of patients with gastrointestinal cancers and correlates with weight loss
Abstract
Proteolysis-inducing factor (PIF), a novel cachectic factor, is detectable in the urine of cancer patients experiencing weight loss. We report the expression of PIF in gastrointestinal cancers, and a correlation between PIF expression in tumours, its detection in urine and weight-loss. These data provide the first direct evidence that tumours are the source of PIF in humans.
