Biosample name: | |
Experiment class : | Low+High throughput |
Enhancer type: | Enhancer |
Disease: | Low-grade astrocytomas |
Pubmed ID: | 29091765 |
Enhancer experiment: | ChIP-seq,ChIP-qPCR,4C-seq,Hi-C |
Enhancer experiment description: | To understand if loss of CTCF binding affects chromatin contacts at the SOX2 locus, we performed circularized chromosome conformation capture (4C-Seq) using the SOX2 promoter as bait to identify genomic interactions that may regulate its expression (Figure 6B, S6B). |
Target gene : | SOX2(ANOP3,MCOPS3),SOX2(ANOP3,MCOPS3),SOX2(ANOP3,MCOPS3) |
Strong evidence: | 4C-seq |
Less strong evidence: | Hi-C |

TF name : | CTCF(MRD21)CTCF(MRD21)CTCF(MRD21) |
TF experiment: | ChIP-qPCR |
TF experiment description: | To assess whether CTCF occupancy at these motifs had changed, we performed ChIP-qPCR for CTCF. Every site assayed had an 2-fold decrease in CTCF occupancy, supporting the hypothesis that DNA hypermethylation in 3-hit NSCs leads to reduced CTCF occupancy around. the SOX2 locus.;To assess whether CTCF occupancy at these motifs had changed, we performed ChIP-qPCR for CTCF.
