(P) ChIP analysis of KLF4 binding to the BRCA1 promoter in MDA-MB-231 at -.3K positions relative to the TSS in untreated and Olaparib (10µM for 8h) or 5Gy radiation treat cells. No significant difference of KLF4 binds to BRCA1 promoter between untreated and Olaparib or radiation treat cells. n=3, p=0.80, one-way ANOVA assay.
