BRD4 is potentially good target of T-ALL. a BRD4 mRNA expression level in a broad range of cancer cells (generated from Broad Cancer Cell Line Encyclopedia: https://portals.broadinstitute.org/ccle). b BRD4 expression was higher in T-ALL patients (n = 16) than normal T cell samples (n = 9) (p = 0.028). BRD4 expression was detected by real-time quantitative reverse transcription polymerase chain reaction (RT-PCR) and relative expression was represented using comparative CT[2 (−ΔCT)]. c, d Overall survival and relapse-free survival curve using RNA-seq data of 46 diagnostic T-ALL patients. First quartile with BRD4 mRNA expression was used as a cutoff point for categorized as high or low expression. Overall survival analysis showed that high BRD4 expression was associated with unfavorable outcomes in pediatric T-ALL patients. Relapse-free survival analysis showed an obvious tendency towards higher relapse-free survival in patients with higher BRD4 expression
