The undecapeptide substance P (SP) after binding to the neurokinin-1 receptor (NK-1R), regulates cancer cell proliferation, exerts an antiapoptotic effect, induces cell migration for invasion/metastasis, and triggers endothelial cell proliferation for neoangiogenesis.
The best-known TK is the vertebrate substance P, which in mammals, together with other TKs, has been implicated in health and disease with important roles in pain, inflammation, cancer, depressive disorder, immune system, gut function, hematopoiesis, sensory processing, and hormone regulation.
Cancer patients received moderately emetogenic chemotherapy (MEC) or highly emetogenic chemotherapy (HEC), and antiemetics palonosetron or granisetron extended-release subcutaneous (GERSC), neurokinin 1 receptor antagonist and dexamethasone.
These results reinforce the previously described activities of the fiscalin B (<b>3</b>) as substance P inhibitor and fumiquinazoline G (<b>1</b>) as antitumor agent showing potential as lead compounds for the development of drugs for treatment of neurodegenerative disorders and cancer, respectively.
While the SP/NK-1R signaling axis is involved in the pathogenesis of solid cancer, the role of this signaling pathway in hematological malignancy remains unknown.
The SP/NK-1R system plays an important role in the molecular bases of many human pathophysiologic processes, such as pain, infectious and inflammatory diseases, and cancer.
In this review, we focus on evidence supporting an association between the signaling pathways of the SP/NK1R system and cancer cell proliferation and development.
Substance P (SP) plays an important role in several types of cancer promotion and progression by binding to its preferential neurokinin 1 receptor (NK1R).
Rolapitant is a neurokinin-1 receptor antagonist that is approved in combination with other antiemetic agents in adults for the prevention of delayed nausea and vomiting (CINV) associated with initial and repeat courses of emetogenic cancer chemotherapy, including but not limited to highly emetogenic chemotherapy.
Intrigued by the contribution of neurokinin-1 receptor (NK1R) network in cancer pathogenesis, we investigated the antileukemic effects of aprepitant, a nonpeptide antagonist of NK1R, in a panel of hematological cell lines.
We aimed to evaluate the serum SP concentration and NK1R tissue distribution in endometrial cancer, and to study the relationship between these factors with tumor size, lymph node involvement, disease stage and cancer grade.
Neurokinin 1 receptor (NK1R) is expressed in gliomas and neuroendocrine malignancies and represents a promising target for molecular imaging and targeted radionuclide therapy.
Efficacy of the oral neurokinin-1 receptor antagonist aprepitant for nausea and vomiting induced by cisplatin and carboplatin in Japanese patients with gynecological cancer.
The substance P (SP)/neurokinin-1 receptor (NK1R) complex has been discovered to be pivotal in the development of a variety of human cancers, and NK1R antagonists, such as the clinical drug aprepitant, are promising future anticancer agents.
It seems that a common mechanism for cancer cell proliferation mediated by SP and the NK-1 receptor is triggered, as well as a common mechanism exerted by NK-1 receptor antagonists on tumor cells, i.e. apoptosis.
In this work, we found that the pain-associated tachykinin Substance P (SP) contributes to persistent transmodulation of the ERBB receptors, EGFR and HER2, in breast cancer, acting to enhance malignancy and therapeutic resistance.
The substance P (SP)/neurokinin-1 receptor (NK-1R) system plays an important role in the development of cancer: SP and NK-1R antagonists respectively induce cell proliferation and inhibition in human cancer cell lines.
Nkx2.8 (Nk2 homeobox 8), a novel member of the NK-2 gene family, was reported to play an important role in the development and progression of human cancer.
Thus, 1) the SP/NK-1 receptor system plays an important role in the development of cancer, angiogenesis, and metastasis; 2) a common mechanism for cancer cell proliferation mediated by the SP/NK-1 receptor system occurs; 3) NK-1 receptor antagonists act as a broad-spectrum antitumoral agent; 4) the NK-1 receptor could be a new promising target in the treatment of cancer; 5) NK-1 receptor antagonists could improve cancer treatment--the development of antagonist molecules of the NK-1 receptor represents an important opportunity for exploiting these molecules as novel therapeutic agents.
