Western blot analysis was carried out as previously described [30]. Primary antibodies used in western blot were listed as below: PLK4 (#NBP1-33042, Novus, USA), LATS1 (#3477, Cell Signaling Technology, USA), phospho-LATS1 (Thr1079) (#8654, Cell Signaling Technology), YAP (#14074, Cell Signaling Technology), phospho-YAP (Ser127) (#13308, Cell Signaling Technology), cleaved PARP (#5625, Cell Signaling Technology), γ-H2AX (Ser139) (#9718, Cell Signaling Technology), phospho-ATM (Ser1981) (#5883, Cell Signaling Technology), phospho-ATR (Ser428) (#2853, Cell Signaling Technology), phospho-Chk1(Ser345) (#2348, Cell Signaling Technology), phospho-Chk2 (Thr68) (#2197, Cell Signaling Technology), anti-Histone H3 (#4499, Cell Signaling Technology). β-actin was used as a loading control. Chemiluminescent signals were detected using the Amersham Imager 600 imaging system (General Electric, USA). ImageJ software (National Institutes of Health, Bethesda, MD, USA) was used to quantify the protein bands normalized to control.
