ChIP-Seq of DNA lesions from irradiated and non-irradiated HaCaT cells

This study aims to investigate the binding DNA lesions of AIM2 in HaCaT cells exposed to 0Gy and 20Gy by ChIP-Seq. In this study, HaCaT cells were maintained in DMEM. All culture media were supplemented with 10% fetal bovine serum (FBS; Biological Industries, Kibbutz Beit-Haemek, Israel). Cells were grown at 37 °C in 5% CO2 incubators. Cells were exposed to 20Gy of ionizing radiation using X-ray linear accelerator (Rad Source, Suwanee, GA) at a fixed dose rate of 1.15 Gy/min.Four hours after irradiation, specific antibody against AIM2 was used to pull down AIM2 and the binding DNA lesions, which was then analyzed through ChIP-Seq. The feature of AIM2 binding DNA lesions were compared through ChIP-Seq in HaCaT cells exposed to ionizing radiation or not.
