BLM regulates HR in BRCA1Δ11 cells. (A) Western blot analysis of EJ-DR reporter cells transfected with siRNA oligos and/or BRCA1 expression vector or control empty vector (EV). (B) Representative flow cytometry data in the U2OS EJ-DR reporter assay, in which HR-mediated repair of I-SceI–mediated DSBs produces GFP fluorescence and mutagenic NHEJ (mNHEJ) produces DsRed fluorescence. (C) Analysis of relative HR frequency in the U2OS EJ-DR reporter cell line. (D) Analysis of relative mNHEJ frequency in the U2OS EJ-DR reporter cell line. Graphs represent mean ± SD of three independent experiments.
