More recently, it has been reported that DR5 displays pro-metastatic activity in KRAS derived non-small-cell lung cancers and pancreatic ductal adenocarcinoma (PDAC), and high expression levels of DR5 are correlated with increased invasion and reduced metastasis-free survival in KRAS mutated patients suffering from PDAC or colorectal cancer, respectively [8]. This evidence concerns the gene KRAS and non-small cell lung carcinoma.
