doi: 10.1016/j.isci.2026.117149

Figure Lengend Snippet: The BmMKLP1 domains exhibit divergent nuclear and cytoplasmic localization (A) Subcellular localization of transiently expressed GFP-tagged domains (green) in BmN4 cells. Representative merged bright-field and GFP fluorescence images acquired at 10×, scale bars, 100 μm, BmN4 cells expressing the indicated constructs were imaged by differential interference contrast (DIC) microscopy (left) to show cell morphology and by fluorescence microscopy (right) to detect GFP-tagged proteins. All images were acquired with a 40× objective lens. Scale bars, 20 μm. (B) Western blot analysis of protein extracts from transfected BmN4 cells probed with an anti-GFP antibody (1:1,000, Proteintech, Wuhan, China), confirming the production of each GFP-tagged domain at its expected molecular weight. The “control” lane corresponds to the cycle 3 GFP-bleo fusion protein (∼39–40 KDa) expressed from the pIZT/V5-His vector. A representative blot from three independent experiments is shown. The PageRuler Prestained Protein Ladder (10–180 kDa; Thermo Fisher Scientific, Waltham, MA, USA) was used as a molecular weight marker.

Figure Lengend Snippet: The head and stalk domains induce G2/M arrest, whereas the tail promotes polyploidization (A) Representative flow cytometry histograms showing DNA content profiles (top) and polyploidy distributions (bottom) for control cells and cells expressing GFP-tagged BmMKLP1—full-length, head, -stalk, or -tail. Cell cycle phases (G0/G1, S, and G2/M) were determined by model-based fitting of propidium iodide (PI) fluorescence intensity histograms. Polyploidy histograms depict cells with DNA content exceeding 4 N. (B) Quantification of cell cycle distribution under each condition. Bars represent the mean ± SEM percentage of cells in G0/G1, S, and G2/M phases from at least three independent experiments. Different lowercase letters indicate significant differences (one-way ANOVA followed by Tukey’s HSD, p < 0.05). (C) Percentage of polyploid cells under each condition. Bars represent mean ± SEM, with statistical significance assessed as in (B).
