Figure 2. LMW-E overexpression leads to mitotic defects.
A. Cells were treated with doxycycline (1 μg/ml) for 24 h, fixed, and stained for β-tubulin (green), γ-tubulin (red), or DNA (blue) and analyzed by IF microscopy. B, Quantification of spindle defects in 200 mitotic cells 200 cells/experiment from ten independent experiments. Data are shown as the percentage of cells with mitotic defects and error bars indicate SD. *P < 0.001. C, Pictorial presentation of various mitotic errors (micronuclei, chromosomes missegregation, anaphase bridges, cytokinesis failure) in LMW-E–overexpressing cells. D, Quantification of mitotic errors in control, EL-expressing, and LMW-E–expressing cells. Graphs indicate the percentage of cells with micronulei, metaphase chromosome missegregation, anaphase bridges, and cytokinesis failure (mean +/− SD, n = 3). *P < 0.01, **P <0.001.
