Figure 7.

HeLa cells depleted of CENP-E recruit reduced amounts of BubR1 to their kinetochores and have many misaligned chromosomes. (A) HeLa cells depleted of CENP-E (green) by RNAi (bottom) recruit less BubR1 (red) to their kinetochores than HeLa cells treated with control RNAi (top) after a 30-min treatment with 200 ng/ml colcemid. DNA, blue. (B) Quantitation of the normalized integrated intensity of BubR1 signals at kinetochores in HeLa cells (top) and primary MEFs (bottom). Control kinetochores (blue bars) recruit more BubR1 than CENP-E–depleted kinetochores (red bars). ≥800 kinetochores from ≥10 cells were quantitated for each bar. **, P < 0.001. Error bars represent standard error. (C) Histogram showing the number of misaligned chromosomes per pseudo metaphase cell in CENP-EΔ/Δ MEFs (red bars) and in HeLa cells depleted of CENP-E by RNAi (green bars).
