Figure Lengend Snippet: Cytotoxic effect of compounds 5a-5e on MCF-7 cells following exposure to different concentrations (10, 20, 60, and 100 μM). Data are presented as mean ± SD, n = 3. *P < 0.05, **P < 0.01, and *** P < 0.001 indicate significant differences in comparison with the negative control group (untreated cells); doxorubicin was used as the positive control.

Article Snippet: The MCF-7 (human breast cancer) cell line was acquired from the Pasteur Institute of Iran (Tehran, Iran).

Figure Lengend Snippet: Analysis of the selected senescence markers and anillin levels in HCT116 p53WT and MCF-7 cells induced to senesce by 1 day-treatment with doxorubicin and collected 5 days after senescence induction. ( A, B ) Densitometric analysis of protein levels in HCT116 p53WT ( A ) and MCF-7 ( B ), n=9; statistical analysis was performed using paired one-tailed t-Student test. Relative protein expression means fold change (in the expression of proteins relative to the expression of GAPDH) vs appropriate control. Boxes: Q1, median, Q3; error bars: Minimum, Maximum. ( C ) Representative images from Western blotting of HCT116 p53WT and MCF-7 cell lysates. ( D, E ) Analysis of fluorescence intensity of anillin (whole nucleus area) and representative images ( F, G ) of control and doxorubicin-treated HCT116 p53WT ( D, F ) and MCF-7 cells ( E, G ), n=3; statistical analysis was performed using Wilcoxon matched-pairs signed-rank test. Data on graphs represent individual values for analyzed cells, median, error bars: Minimum, Maximum. Red – anillin, blue – DAPI stained DNA. Scale 20 µm. Statistical significance relative to control: ** p ≤ 0.01, *** p ≤ 0.001, **** p ≤ 0.0001

Article Snippet: The human HCT116 p53-proficient (referred to as HCT116 p53WT) colon cancer cell line and the breast cancer cell line MCF-7 were obtained from ATCC (HCT116 CCL-247; MCF-7 HTB-22).

Figure Lengend Snippet: Correlation between p53 and anillin levels during senescence and the escape from senescence in breast cancer MCF-7 and colon cancer HCT116 p53WT cells (see ). ( A-B ). Representative Western blots showing the levels of anillin and p53 in HCT116 p53WT cells ( A ) and MCF-7 cells ( B ). ( C-F ) The level of anillin and p53 on subsequent days of cell culture after senescence induction by doxorubicin in HCT116 p53WT ( C and E ) and MCF-7 cells ( D and F ) n = 4; statistical analysis was performed using one-way ANOVA followed by post hoc analysis (Tukey’s honest significant difference test; HSD test). Statistical significance of differences between indicated days of treatment: * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001. Boxes: Q1, median, Q3; error bars: Minimum, Maximum. ( G ) The heat map shows the levels of anillin and p53 during senescence and escape from senescence in MCF-7 and HCT116 p53WT cells. Heatmap: Original data points are standardized into z-scores.
