FAS and neoplasm: This data set comprises tumour- and non-tumour-matched samples obtained from 36 pancreatic cancer patients at the time of surgery.17 After normalization, we found that CD95 expression is significantly higher in tumour samples compared with non-tumour samples (Figure 1a), and that most patients show an increase in the expression of CD95 as compared with surrounding non-tumour tissue (Figure 1b).
