Figure Lengend Snippet: a, Schematic overview of the generation of HCT116 cell pools stably overexpressing BRIP1 WT or BRIP1 R162Q. BRIP1 WT or R162Q constructs contained C-terminal c-Myc and HA epitope tags. b, Representative Sanger sequencing traces confirming the presence of BRIP1 WT or BRIP1 R162Q in transduced HCT116 cells. c, d, Immunoblot analysis confirming expression of BRIP1 and Myc-tagged proteins in HCT116 cells expressing BRIP1 WT or R162Q, detected using BRIP1 and Myc antibodies. Vinculin served as a loading control. e, j, Functional characterization of HCT116 cells expressing BRIP1 WT or R162Q by colony formation assays following e, mitomycin C (MMC) (0.5;1; 2; 3; 4 μM/ml), g, ionizing radiation (IR) (2; 3; 4; 5 Gy), and j, hydroxyurea (HU) treatment 50;100;150;200;250 μM/ml). Representative colony plates (upper panels) and quantification of survival fractions (lower panels) are shown. Quantification was performed using EagleEye analysis software. Data represent the mean ± SD of three independent biological replicates.
