TNFSF10 and neoplasm: Treatment of orthotopic pancreatic cancer xenografts with either gemcitabine, JNKi or TRAIL alone for 4 weeks showed only modest effects compared to control, while the combination of JNKi and TRAIL resulted in significantly lower tumor burden (69%; p < 0.04), reduced numbers of circulating tumor cells, and less distant metastatic events, without affecting the general health of the animals.
