Fig. 4

a Western blot verification of the knockdown (KD) or overexpression (OE) of MTA1 in the HCT116 cells. Shown is representative of three independent repeats with similar results. b, c Flow cytometry measurement of the mitotic-arrest cell proportion in MTA1-deletion, control or MTA1-overexpression HCT116 cells after nocodazole treatment for 6 h and 12 h. Propidium Iodide (PI) was used to stain the nuclear DNA, and the G2/M cells were marked with 4 N DNA content. d, e Flow cytometry measurement of the mitotic-arrest cell proportion after the nocodazole treatment for 6 h, 12 h and 18 h. The mitotic cells were marked by antibody against mitosis-specific phosphorylated Histone 3. f Flow cytometry measurement of the mitotic-arrest cell proportion in control and EGFP-MTA1 stably expressing HCT116 cells after nocodazole treatment for 18 h. g The overexpression of MTA1 in the KYSE-410 cancer cells also resulted in a lower mitotic arrest by nocodazole. c, e Data are represented as mean ± SD, n = 3 per group.
