Abstract
The progression of esophagus cancer (EC) is associated with the alterative expressions of multiple microRNAs (miRs). MiR-1-3p is reported to inhibit the development of EC by targeting TAGLN2. Quercetin (Que) is a natural compound capable of antagonizing esophagus carcinoma (EC). In the current study, the role of miR-1-3p/TAGLN2 axis in the anti-EC function of Que was explored. Human EC cell lines KYSE-510 and TE-7 were treated with Que. Then the effects of Que on the growth and metastasis of EC cells, and on the activity of miR-1-3p/TAGLN2 axis were detected. The interaction between Que and miR-1-3p axis was further assessed by inhibiting miR-1-3p level in EC cells. The results showed that the treatment of Que impaired the growth and induced cell apoptosis in EC cells. The invasive ability of EC cells was also suppressed by Que. At molecular level, the expression of miR-1-3p was induced, while the expression of TAGLN2 was suppressed by Que. Moreover, the anti-EC effects of Que were blocked by miR-1-3p inhibition, which was represented by the restored growth and invasion of EC cells. Collectively, the current study demonstrated that Que exerted inhibitory effects on EC cells by inducing miR-1-3p.
