The Role of Signaling Pathways in Pancreatic Cancer Targeted Therapy

Signaling pathways play significant roles in the occurrence, development, and treatment of pancreatic cancer (PC). The main treatment options are surgery, chemotherapy, radiotherapy, arterial infusion chemotherapy in interventional therapy, and immunotherapy. Many studies have shown that signaling pathways perform a function in the occurrence and development of PC, for instance, phosphoinositide 3-kinase (PI3K)/AKT, nuclear factor-kappa B, Ras, interleukin (IL)-17B/IL-17RB, Wnt, and hepatocyte growth factor/c-MET, which play roles in the proliferation, metastasis, invasion, inhibition of apoptosis, promotion of angiogenesis, and drug resistance of PC. Interaction of signaling pathways has an impact on the biological behavior of PC; for example, activation of the neurotensin/NTSR1 pathway, which can activate mitogen-activated protein kinase, nuclear factor-kappa B, and other pathways related to PC stem cells, play an important role in PC, and an increase in their number is associated with the Wnt/beta-catenin and PI3K pathways. Chemotherapy is the main method for the treatment of PC, but drug resistance limits its use. In addition, abnormal activation of IL-17B/IL-17RB signaling pathway is associated with drug resistance. This article discusses the signaling pathways that play different roles in the occurrence and development of PC, as well as current research on signaling pathways in PC treatment.

Automated summary

Signaling pathways, including phosphoinositide 3-kinase (PI3K)/AKT, nuclear factor-kappa B, Ras, interleukin (IL)-17B/IL-17RB, Wnt, and hepatocyte growth factor/c-MET, play important roles in the occurrence, development, and treatment of pancreatic cancer (PC). Chemotherapy is the main treatment method, but drug resistance is a major limitation. Abnormal activation of IL-17B/IL-17RB signaling pathway is associated with drug resistance. This article discusses the different roles of signaling pathways in PC and current research on their treatment.
