RECQL5 depletion is associated with late S-phase cycling defects. Representative flow cytometry images of (A and B) HeLa and (C and D) HCT116 scrambled and RECQL5 knockdown cells analyzed for the ability to incorporate bromodeoxyuridine (BrdU) and plotted against DNA content in (A and C) a 30 min BrdU pulse and (B and D) 24 h pulse. For panels A and C, the fraction of BrdU positive cells are denoted in the upper left. The late S-G2 of the BrdU positive cells subpopulation, boxed area, is also quantified in the upper right. For panels B and D, the first generation slow late S-G2 population is boxed and quantified.
