RNA-seq on ZNF417/587 double KO K562

To verify ZNF417 and ZNF587 knock out whether leads to HERV-K element reactivation, we performed RNA-seq on ZNF417/ZNF587 double knock out (DKO) K562 cell lines. We observed a dozen of genes were upregulated in KO cells, and some of them possessed PBS-Lys sites near their promoters that can be directly targeted by ZNF417 and ZNF587, such as MS4A clusters. We also measured the expression levels of repetitive elements in ZNF417 ZNF587 dKO cells, which exhibited only some ERVs reactivation indirectly. Two DKO cell lines and two control KO cell lines were used to perform RNA-seq.
