Figure 4. Silencing of HERV-H sequences weakened the TAD boundaries in hESC.
(a) Design of the CRISPR-dCas9-KRAB system to silence HERV-H expression using sgRNAs targeting 5’ LTR7. (b) Gene expression values of HERV-H1 and HERV-H2 in WT and CRISPRi-targeted hESCs. (c) Hi-C interaction matrices of the CRISPRi targeted hESC lines (sgHERV-H1 and sgHERV-H2) are shown, along with DI scores, and log2(fold-change) of gene expression in engineered cell lines over control at the HERV-H1 and HERV-H2 loci.
