miR-300 inhibits the proliferation and invasion abilities.

Notes: (A, C) Tca8113 and Cal-27 cells were transfected with miR-300 mimics and inhibitor for 48 hours. The levels of miR-300 were determined by reverse transcription quantitative PCR assay. (B, D) The cells were treated as indicated above, and the cell proliferation ability was determined by MTS assay. (E, F) The cells were treated as indicated above, and the cell invasion ability was determined by Transwell. *P<0.05, **P<0.01.

Abbreviations: PCR, polymerase chain reaction; NC, negative control.
