Figure 3 |. Functional loss of EWSR1 impairs homologous recombination.
a, Representative immunofluorescence images of TP53BP1 and RAD51 foci. Scale bar, 25 μm. b, c, Number of cells with more than five TP53BP1 (b) or RAD51 (c) foci. n = 85 cells, two-tailed t-test. d–h, Homologous recombination (HR) frequency with indicated transfections (efficiency demonstrated in Extended Data Figs 5d, 6d). n = 3 transfection replicates, one-way ANOVA. i, Immunoblots for BRCA1 and EWS–FLI1 in subcellular fractions of TC32 cells with EWS–FLI1 knockdown. Mean ± s.e.m.; #,*P < 0.05; ##,**P < 0.005, # shows significance relative to control (black bar).
