NK1 receptor antagonistic effect of 17-trifluoromethyl phenyl trinor prostaglandin F2α on the growth of human breast cancer cell line

Abstract

BackgroundA growing number of genetic and cancer biology investigations have found that the tachykinin NK1 Receptor plays an important role in cancer cell proliferation and survival. In this study. The present study was designed to evaluate the inhibition of cell growth by 17-trifluoromethyl phenyl trinor prostaglandin F2α with NK1 receptor in breast cancer cell lines. Materials and methodsMDB-MB-468 and MCF-7 breast cancer cell lines were used in the experiment were blocked with PGF2a. Cell proliferation and apoptosis were analyzed to evaluate the cytotoxic effect. Cell cycle distribution, Caspase-3 enzyme activity, Bad and Bax protein expression through flow cytometry and molecular docking were carried out to analyze the NK1 receptor activity. ResultsWe found that PGF2a has a high binding affinity towards NK1 Receptor from molecular docking studies. It exerted cytotoxic and antiproliferative effects against MDB-MB-468 and MCF-7 breast cancer cell lines. Our data found that treatment of cells with 17-TPGF2 resulted in cell death and showed that increased expression of Caspase-3, Bad, and Bax protein and further induces G2 cell cycle arrest. ConclusionOverall this study investigates the NK1 receptor antagonistic effect of PGF2 against breast cancer cell lines. However, further studies are needed to better characterize the application of NK1 receptor inhibition in clinical cancer treatment and cytotoxicity effect.
