图1:编码BATF3和IL-2R亚基的基因在H3K27高度乙酰化,并呈正相关。a增强子根据增加的H3K27ac信号进行排名。在Karpas-299 (ALK+)和Mac-1 (ALK−)ALCL细胞系中,SEs内的基因被标记为红色。b H3K27ac ChIP-seq在BATF3位点进行追踪,显示SE区域。c Karpas-299和Mac-1细胞系中SEs相关基因的重叠。d增强子根据增加的H3K27ac信号进行排名。原发性ALCL患者样本(#54和#208)中SEs内的基因用红色标记。e通过IPA 2020分析,鉴定CRISPR/ cas9介导的BATF3-KO Karpas-299细胞中去调控基因的上游调控因子。f先前发表的23例ALCL患者RNA-seq数据集中batf4相关基因的分析(BioProject PRJNA255877, SRA标识符SRP044708)。皮尔森相关; P value based on t-distribution. g Representative images of 63 patient samples measured of BATF3 and IL-2Rα IHC staining of ALCL, ALK+ in paired FFPE tissues sections. h IHC quantification of IL-2Rα, IL-2Rβ and IL-2Rγ expression in mature T-NHL TMAs (reactive lymph node controls, n = 11; AITL, n = 8; PTCL-NOS, n = 23; ALCL, ALK+, n = 22; ALCL, ALK−, n = 23) and pcALCL (n = 24) specimens. P values were determined by two-tailed unpaired Student’s t test. All box-whisker plots represent the median (central line), 25th–75th percentile (bounds of the box) and minimum–maximum (whiskers).
