GATAD1 and glioblastoma: Then we used ChIP‐qPCR to detect the histone modification condition after GATAD1 knockdown, the result showed that, in both GBM cells, GATAD1 shRNA transfection would inhibit the histone H3K9Ac and H3K27Ac modification of GATAD1 binding sites on CCND1 promoter (Figure 6B,C).
