Bulk RNA-Seq to study the effects of CENP-A overexpression, p53 status, and X- irradiation treatment in MCF-10-2A cells


ABSTRACT: We performed bulk RNA-Seq to investigate global transcriptional changes upon overexpression of the centromeric H3 variant CenH3/CENP-A in p53 wild-type and defective cells, and after X-irradiation treatment. We established clonal MCF-10-2A TetOn-CENPA-FLAG-HA cell lines where CENP-A can be reversibly induced by Doxycycline (Dox) treatment. Upon CENP-A overexpression, these cells exhibit different radiosensitivity depending on p53 status. In order to profile global changes in expression, we compared MCF-10-2A TetOn-CENPA-FLAG-HA cells expressing either empty vector (p53-WT) or dominant-negative p53 (p53-DN) with 0X Dox (no Dox), 1X Dox (10 ng/ml), or 10X Dox (100 ng/ml) for 24h. At time 0, we irradiated one set of cells by X-ray generator (4gy) while a control set remained un-irradiated (0gy). 6h later, we extracted RNA for RNA-seq.
