Nasopharyngeal carcinoma (NPC) is a malignant tumor of the nasopharynx.Here, we aimed to understand better the molecular basis for arctigenin (ARG)'s ability to promote NPC 5-8F cell invasion.We tested the effects of several doses of ARG on 5-8F cells that had been cultured in vitro. We have estimated the metabolic activity of cells by The MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) tetrazolium assay. We examined the influence on cell invasion, and migration using Transwell Evaluation. Real-time polymerase chain reaction analysis was used to determine the relative amounts of epidermal growth factor receptor (EGFR), Janus kinase 2 (JAK2) , and transcriptional activator 3 (STAT 3) mRNA expression. Using western blotting, we looked at the level of phosphorylation of specific proteins like EGFR, phosphorylated EGFR, JAK2, and STAT 3.Our findings revealed that ARG inhibited NPC 5-8F cell development in a dose- and time-dependent manner. The invasiveness and mobility of 5-8F cells were significantly suppressed when ARG was overexpressed in a tumor development model. Expression levels of EGFR, JAK2, and STAT 3 mRNA were considerably low in the experimental group. As a consequence of being treated with ARG, lower levels of EGFR, p-EGFR, p-JAK2, and p-STAT3 expression were observed.These results suggest that ARG may prevent NPC 5-8F cells from proliferating, migrating, and invading other tissues. There are a few potential molecular pathways, two of which are the inhibition of EGFR phosphorylation and the reduction of levels of phospho-JAK2 and phospho-STAT3.Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.
