Figure Lengend Snippet: Effect of ATRi on HR repair in reporter cell lines. (A) Western blot results of ARID1A knock-down in DR-GFP-U2OS and DR-GFP-A549 reporter cells; GAPDH was used as an internal control. (B) Normalized GFP expression in DR-GFP- U2OS and DR-GFP-A549 reporter cells after treatment with control siRNA (mock), 20 nM VE822 (ATRi), ARID1A specific siRNA (siARID1A) and ATRi after knock-down of ARID1A (siARID1A, ATRi). (C) Normalized GFP expression in SA-GFP- U2OS reporter cells after treatment with control siRNA (mock), 20 nM VE822 (ATRi), ARID1A specific siRNA (siARID1A) and ATRi after knock-down of ARID1A (siARID1A, ATRi). (D) Normalized GFP expression in EJ2-GFP- U2OS reporter cells after treatment with control siRNA (mock), 20 nM VE822 (ATRi), ARID1A specific siRNA (siARID1A) and ATRi after knock-down of ARID1A (siARID1A, ATRi).Results of 3 independent experiments are shown for CRC cell lines.
Article Snippet: The human CRC cell lines with mutant (LS180, RKO, SW48) and wild-type (HCT15, HCT116 and Colo320DM) ARID1A were obtained from ATCC (LGC Standards, Wesel, Germany) and were designated as ARID1A - and ARID1A + cells, respectively.
