Figure Lengend Snippet: (A) RNAPII ChIA-PET linkages at the MYC locus. ChIP-seq tracks were shown on the top. MYCSE1 (-525kb from TSS) and MYCSE2 (-428kb from TSS) were indicated by red box below the tracks. RNAPII ChIA-PET links were shown by magenta lines. Orange boxes indicated the regions targeted by CRISPR. (B) Validation of MYCSE1 Deletion. Cas9 stable LCLs or BJAB were transduced with paired gRNA targeting the edges of ESE. After puromycin selection, genomic DNA was prepared from LCLs and BJAB cells transduced with dual gRNA. The targeted region was PCR amplified. The presence or absence of the MYC SE1 was shown. (C) MYCSE1 deletion reduced MYC mRNA level. 2 independent pairs of gRNAs both decreased MYC mRNA by qRT-PCR normalized to b-actin. Control gRNA treated cells were set to 1. (D) Growth of MYCSE1 deleted LCLs and LCLs with deletion in a control region. (E) MYCSE2 deletion also reduced MYC mRNA level. 2 independent pairs of gRNAs both decreased MYC mRNA by qRT-PCR. All data are represented as mean+/−SE. See also Figure S3.
Article Snippet: Dual gRNAs were cloned into pLentiGuide-Puro (Addgene Plasmid #52963) using the Multiplex gRNA kit (System Biosciences) according to the manufacturer protocol.
