Figure Lengend Snippet: Development of a nuclear transport-independent NE rupture reporter. A) Illustration of the transport-dependent BAF-IRES-GFP-NLS rupture reporter system for co-expression with BAF variants. P LTR , long terminal repeat promoter.

Figure Lengend Snippet: Endogenous BAF is sufficient to respond to NE ruptures with gradual depletion leading to a progressive loss of that response. A) Representative images of BJ5ta cells expressing either Empty- or WT-BAF-IRES-Hsp90-GFP and cGAS-mCherry, treated with either siControl or siBAF for 96 hr and followed through NE rupture to observe the extent of leakage. The enrichment of cGAS (yellow arrows) along the nuclear periphery (outlined in red for clarity) signal the location and time of NE rupture. Scale bar, 10 µm. B) Quantification of the nuclear- to-cytoplasmic increase in Hsp90-GFP following laser-induced NE rupture from cells. The graph represents mean values ± SEM of Empty siControl (n= 18), Empty siBAF (n=18), WT-BAF siControl (n=5) and WT-BAF siBAF (n=11) cells from at least three independent experiments. C) Rates of Hsp90-GFP leakage into the nucleus during the first 30 seconds following NE rupture. D) Repair check, measured as a percent increase in nuclear-to-cytoplasmic Hsp90-GFP diffusion into the nucleus following nuclear photobleaching (performed 10 minutes after NE rupture) to check functional repair. The graph represents mean values ± SEM of Empty siControl (n = 4), WT-BAF siControl (n = 5), WT-BAF siBAF (n = 8) and Empty siBAF (n = 10). E) Representative Western blot of cell lysates from cells treated with 0, 0.1, 1 and 10 pmol of BAF siRNAs for 72 hr, with tubulin used as a loading control.
