doi: 10.1126/sciadv.aec7779
Figure Lengend Snippet: ( A ) Analysis of ChIP-seq data of p300 (black), histone (blue), NFATc1 (green), and in situ Hi-C data at the IL10 locus using public datasets ( GSE32465 , GSE29611 , and GSE63525 ) of GM12878 human immortalized B cells. ( B to E ) Raji B cells were electroporated with vectors expressing Cas9 and sgRNAs targeting NFAT-binding motifs in IL10 CNS-12 or mock vectors. (B) Schematic diagram of the NFAT-binding motifs in IL10 CNS-12, identified with rVISTA (Transfac matrices, similarity score of 0.85). Red arrows indicate sgRNA targeting sites. (C) qRT-PCR analysis of IL10 mRNA in electroporated human Raji B cells, expressed as fold change relative to unstimulated cells. [(D) and (E)] Representative flow cytometry plots (D) and frequency (E) of IL-10 + cells in Raji B cells ( n = 3 for mock, sgRNA 1, and sgRNA 2). A FMO control for IL-10 is shown in (D). ( F ) IL-10 concentrations in culture supernatants of Raji B cells measured at 4 and 24 hours ( n = 3 for mock, sgRNA 1, and sgRNA 2). Data are pooled from three independent experiments [(C), (E), and (F)]. Data are presented as means ± SEM. Statistical analysis was performed using a two-tailed unpaired Student’s t test [(C), (E), and (F)]: * P < 0.05, ** P < 0.01, and **** P < 0.0001.
Article Snippet: A20 and Raji B cell lines were obtained from the American Type Culture Collection (MD, USA).
