Figure Lengend Snippet: A. The bar chart corresponds to the mean of three independent proliferation experiments for the 3 TERT + cell lines on one hand and for the 3 ALT + cell lines on the other hand. For each cell line 1200 cells were seeded and proliferation was assessed at days 3, 4 and 5 (Fig. S10). Results presented here show the mean cell count on day 5 ± SD. Mann-Whitney test. ***: p < 0.001. B. Stacked bar chart presenting the result of three independent experiments in which cell fractions in G1, S and G2/M phases of the cell cycle were assessed using propidium iodide labelling for 2 TERT + hybrid cell lines and 3 ALT + cell lines. HBT3 TERT + cell line could not be analyzed because of the presence of two populations with different ploidies. Results correspond to the mean ± SD. Two-way ANOVA with Sidak’s correction for multiple comparisons test. **: p < 0.01 and ****: p < 0.0001. Individual data for each cell line are presented in Fig. S11. C. The bar chart corresponds to the mean of three independent proliferation experiments for the 3 control cell lines (-DOX, in red) and for the 3 cell lines under DOX treatment (+DOX, in blue). Two shRNAs were used (sh2 & sh3). Results are mean ± SD. Unpaired t-test with Welch’s correction. No significant result. BLM inhibition induced by DOX treatment was assessed in parallel by real-time quantitative RT-PCR and western blot (Figs. S12A and S12B). Individual data for each cell line are presented in Fig. S12C.

Article Title: The NewroBus platform: engineered humanized anti-TfR1 nanobodies for efficient brain delivery

doi: 10.1186/s12964-025-02605-1

Figure Lengend Snippet: TfR1 binding and TNFα inhibitory activity of optimized and humanized heterodimers. a Schematic representation of the 16 humanized and optimized TNFI–TfR1b heterodimers. b Flow cytometry analysis in HEK293 cells stably expressing human TfR1, comparing the binding of heterodimers to that of their parental humanized TfR1b-Nbs. c ) Dose–response apoptosis inhibition curves in WEHI-13VAR cells treated with human TNFα and twofold serial dilutions of TNFI–TfR1b heterodimers (100,000 to 12.21 pM). Apoptosis was measured using a fluorogenic caspase-3/7 activation assay. Caspase-3/7 activity in the TNFα-only samples was defined as 100%. The IC₅₀ values of the heterodimers were comparable to those of the parental humanized nanobodies TNFI-α (IC₅₀ = 48.84 pM, range: 42.11–56.56) and TNFI-β (IC₅₀ = 64.31 pM, range: 57.17–72.31).). Data are presented as mean ± SEM from triplicate measurements and were analyzed using the "Inhibitor vs. Normalized Response" model in GraphPad Prism 10 software

Article Snippet: Plates were immediately placed in the Incucyte Live-Cell Imaging System (Sartorius), and fluorescent signals were monitored every 2–4 h for up to 24 h. Fluorescent caspase-3/7 signal intensity was quantified using Incucyte analysis software.

Article Title: Senescent cells secrete chromatin components via senescence-associated extracellular particles

doi: 10.64898/2025.12.12.694055

Figure Lengend Snippet: ( A ) Schematic representation of the experimental approach used to test whether senescent cell–derived small extracellular vesicles and particles (EVPs) can be taken up by proliferating cells. Proliferating IMR90 cells were treated with PKH67, a green fluorescent lipophilic membrane dye, alone or with PKH67-labeled EVPs isolated from senescent cells. ( B ) Representative immunofluorescence images of proliferating cells treated with or without PKH67-labeled sEVP fractions from senescent cells, using different sEVP volumes while keeping the PKH67 lipid dye concentration unchanged. Boxes indicate expanded region and arrows indicate PKH67 puncta in recipient cells. ( C ) Quantification of internalized PKH67-labeled sEVPs by proliferating cells. Data are presented as mean ± SD (n=3 independent experiments). Statistical significance was determined using two-sided one-way ANOVA: *p=0.023, **p=0.0010, ****p<0.0001. ( D ) Schematic representation of the experimental setup: proliferating IMR90 cells were treated with no sEVPs or sEVPs secreted by proliferating cells treated with DMSO, or senescent cells treated with the inhibitor of CCF formation, MDM2 inhibitor RG7388 (MDM2i) or DMSO vehicle. ( E ) Quantification of cGAMP concentration in proliferating cells treated with no sEVPs or sEVPs (40 μL) from proliferating cells treated with DMSO, or senescent cells treated with MDM2i or DMSO vehicle. sEVPs were isolated from equivalent numbers of cells for each condition and resuspended in identical buffer volumes. Data are presented as mean ± SD (n = 3 independent experiments). Statistical significance was determined using two-sided one-way ANOVA: *p=0.011, **p=0.0094.
