Abstract:

The neuropeptide substance P (SP) and its receptor, neurokinin-1 receptor (NK-1R), play a critical role in the occurrence and development of tumors. As a member of the G protein-coupled receptor superfamily, aberrant activation of NK-1R is closely related to the proliferation and metastasis of lung cancer. Studies have shown that SP/NK-1R promotes the proliferation of tumor cells by regulating signal pathways such as MAPK and PI3K/Akt, and anticipates in the remodeling of the tumor microenvironment to drive angiogenesis. In recent years, an increasing number of preclinical studies have found that NK-1R antagonists not only serve as antiemetic drugs widely used for the prevention of chemotherapy-induced nausea and vomiting, but also have direct anti-tumor effects. Some of the mechanisms include reversing epithelial-mesenchymal transition and inhibiting the vascular endothelial growth factor pathway. The systematic elaboration of NK-1R's mechanisms in lung cancer and research progress of its antagonists can lay a foundation for exploring new treatment paths for lung cancer and ultimately improving therapeutic efficacy and the quality of patients′ lives.
