The DNA damage response is not involved in ACOT7 depletion-mediated cytostasis. (a–d) After transfection of ACOT7 Si (a and d), or after exposure to 6 Gy IR (b), or after treatment with 50 ng/ml Doxo (c), MCF7 cells were harvested at the indicated time intervals. Western blotting analysis was performed with anti-phospho ATM and anti-γH2AX. (e) Immunocytochemical staining of γH2AX (green) was conducted at 1 day after transfection of ACOT7 Si. DNA was counterstained with DAPI (blue). Cells exposed to 6 Gy of IR were used as the positive control (PC)
