Our present data, together with published results, suggested that ciRS-7 might be a potential target for ESCC treatment. Funding Statement This research was supported by the Basic research project (Natural science funds) of Jiangsu Province (NO. our present study revealed that ciRS-7 can trigger the migration and invasion of ESCC cells via miR-7/KLF4 and NF-B signals. Targeted inhibition of ciRS-7 might be a potential approach for ESCC treatment. migration of both KYSE150 (Physique 2C) and Eca9706 (Physique 2D) cells. This was confirmed by transwell analysis that over expression of ciRS-7 also significantly increased the invasion of both KYSE150 and Eca9706 cells (Physique 2E). In addition, increased expression of MMP-2 and MMP-9 was observed in ciRS-7 over expressed KYSE150 and Eca9706 cells (Physique 2F). Collectively, our data showed that ciRS-7 can promote the migration and invasion of ESCC cells. Open in a separate window Physique 2. ciRS-7 increased the migration and invasion of ESCC cells. (A) KYSE150 and Eca9706 cells were transfected with pLCDH-ciR/ciRS-7 or vector control for 24?h, the expression of ciRS-7 was detected by use of qRT-PCR; After transfected with pLCDH-ciR/ciRS-7 or vector control for 48?h, the cell proliferation was detected by CCK-8 kit (B), the migration (C, KYSE150; D, Eca9706) was measured by wound healing assay, the invasion was measured by transwell assay (E), and the expression of MMP-2, MMP-9, and vimentin was measured by western blot analysis (F). ** p?Mouse monoclonal to IgG2b/IgG2a Isotype control(FITC/PE) (Physique 3A). To verify whether miR-7 is usually involved in ciRS-7 induced migration and invasion of ESCC cells, we over expressed miR-7 in KYSE150 and Eca9706 cells (Physique 3B). Our data showed that over expression of miR-7 can partially attenuate ciRS-7 induced invasion of both KYSE150 (Physique 3C) and Eca9706 (Physique 3D) cells. This was confirmed by Paroxetine HCl western blot analysis that over expression of miR-7 reversed ciRS-7 induced over expression of MMP-2 and MMP-9 in KYSE150 cells (Physique 3E). These data indicated that miR-7 is usually involved in ciRS-7 induced migration and invasion of ESCC cells. Open in a separate window Physique 3. miR-7 was involved in ciRS-7 induced migration and invasion of ESCC cells. (A) KYSE150 and Eca9706 cells were transfected with pLCDH-ciR/ciRS-7 or vector control for 24?h, the expression of Paroxetine HCl miR-7 was detected by use of qRT-PCR; (B) KYSE150 and Eca9706 cells were transfected with miR-7 construct or vector control for 24?h; KYSE150 (C) and Eca9706 (D) cells were transfected with pLCDH-ciR/ciRS-7, miR-7 construct or vector control alone or together for 48?h, the cell invasion was Paroxetine HCl evaluated by use of transwell assay; (E) KYSE150 cells were treated as (C), the protein expression was measured by western blot analysis. ** p?
