Article Title: Anillin Recedes in p53-Dependent Senescence of Tumor Cells and Reappears in Cells Escaping from Senescence

doi: 10.14336/AD.2025.0402

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

doi: 10.14336/AD.2025.0402

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.

Article Title: KIF14–AKT axis regulates ferroptosis sensitivity in triple-negative breast cancer

doi: 10.1515/biol-2025-1324

Figure Lengend Snippet: KIF14 modulates ferroptosis sensitivity in MDA-MB-468 cells. (A) KIF14 expression levels in MCF-10A, MDA-MB-231, and MDA-MB-468 cells measured by qRT-PCR. (B) qRT-PCR validation of KIF14 knockdown efficiency in MDA-MB-468 cells transfected with siNC, siKIF14-1, or siKIF14-2. (C) Cell viability in siNC, siNC + Fer-1, siKIF14, and siKIF14 + Fer-1 groups. (D) MDA levels in the indicated groups. (E) Representative FerroOrange images and quantification of intracellular Fe 2+ levels. Scale bar = 100 μm. (F) Cell viability in siNC, siKIF14, siKIF14 + Fer-1, siKIF14 + Z-VAD-FMK, siKIF14 + Nec-1, and siKIF14 + VX-765 groups. Bars without significance brackets indicate no statistically significant difference relative to the siKIF14 group ( P > 0.05). Data are presented as mean ± SD from three independent experiments. *P < 0.05, *** P < 0.001.

Article Title: Ribbon-shaped microgels as bioinks for 3D bioprinting of anisotropic tissue structures

doi: 10.1016/j.bioactmat.2025.12.040

Figure Lengend Snippet: μRB bioinks support multicellular patterning to model breast cancer-bone invasion at tissue interface. (A) Schematic of experimental design: bioprinting of MSCs and osteogenic differentiation to derive bone grid, followed by injection of breast cancer bioink, and monitoring invasion over time using confocal microscopy. (B) Confocal images of MSCs (red) after printing (Scale bar = 1 mm). (C) Confocal images of scaffold sections containing CellTracker-labeled MSCs (red) after 28 days of osteogenic differentiation and GFP + MDA-MB-231 cells extruded into the open pores of the grids (green) (Scale bar = 200 μm). (D) Confocal images of patterned MSC-derived bone (red) with MDA-MB-231 and MCF-7 breast cancer cells (green) after 14 days of co-culture (Scale bar = 1 mm). (E) Quantification of breast cancer cell invasion: percentage that remain in open pores vs. invading into the MSC-bone compartment (n = 5 per group). Values are reported as mean ± S.D. and p-values were determined by two-way analysis of variance (ANOVA) with Tukey's multiple comparisons test; ∗∗p ≤ 0.01, ∗∗∗p ≤ 0.005, ∗∗∗∗p ≤ 0.001.
