Formin mDia1 overexpression rescues nuclear import defects. a, b Time-lapse images and quantification of S-mCherry nuclear import dynamics upon treatment with LMB in cortical neurons expressing GFP or GFP-mDia1 (green) and V5-tagged PFN1 (white). S-mCherry levels are shown as 16-bit heat map. Dashed lines indicate the nucleus. Cells were post-fixed and stained to verify the expression of V5-PFN1 constructs (white). c, d Regression analysis of S-mCherry nuclear import kinetics (c) and percentage of non-responder cells (d). DAPI (blue) was used to detect the nucleus and assess cell health. Scale bars: 10 µm. Bars are mean ± SEM. ***p < 0.001. N = 43–50 cells from 4 independent experiments.
