Allergen‑removed Rhus verniciflua Stokes suppresses invasion and migration of pancreatic cancer cells through downregulation of the JAK/STAT and Src/FAK signaling pathways.

Pancreatic cancer is a leading cause of mortality and morbidity worldwide. Due to drug resistance, and the high toxicity and adverse side effects of existing chemotherapeutic drugs, the current treatment of highly aggressive pancreatic cancer is considered inadequate. Allergen‑removed Rhus verniciflua Stokes (aRVS) has a strong antiproliferative effect in various cancer cells, and due to its low toxicity, it has emerged as an attractive candidate for cancer treatment. However, the potential use of aRVS as a treatment for pancreatic cancer is relatively unexplored. The present study examined the effects of aRVS on the invasion and migration of pancreatic cancer cells, and identified the molecular mechanisms underlying its anticancer effects. aRVS inhibited the Janus kinase/signal transducer and activator of transcription pathway in pancreatic cancer cells, and decreased the protein expression of mucin 4. In addition, it inhibited the activation of focal adhesion kinase and Src signaling, and decreased the expression of matrix metalloproteinase 9, which may reduce the migration and invasion of pancreatic cancer cells. In conclusion, the present study suggested that aRVS may be a potential treatment for aggressive pancreatic cancer.
