Negative regulation of SP1 by miR-129-5p in Hela cells.

<p>(A) Vector restriction map. (B) SP1 was targeted by miR-129-5p via its 3′UTR in Hela cells as assessed using a luciferase assay. (C) Western blot analyses of p21, SP1 and GAPDH in Hela cells after miR-129-5p over-expression. Means (bars) and SD (error bars) are shown.*P<0.05.
