Elevated microRNA-375 expression does not significantly alter total Tks5 (tyrosine kinase substrate with 5 SH3 domains), cortactin, and fascin protein levels in UMSCC1 cells. Representative Western blots of total Tks5 (A), cortactin (B), and fascin (C) protein levels in UMSCC1 transductant lines. β-Tubulin or β-actin was used as a loading control for Western blots. Quantitation of total Tks5, cortactin, and fascin levels in UMSCC1 transductant cells (D) shown as means and standard error of the mean of 5 independent experiments. Abbreviation: n.s., not significant.
