Figure Lengend Snippet: BRD4 inhibitor significantly promotes HCP5 super‐enhancer activity and expression. (A) Reverse transcription‐quantitative polymerase chain reaction analysis of HCP5 mRNA expression levels in acute myeloid leukemia cell lines (THP‐1 and HL‐60) treated with the BRD4 inhibitor GNE‐987. (B) Western Blot analysis showing BRD4 expression levels in different groups. (C) Representative agarose gel electrophoresis image and statistical quantification of ChIP‐qPCR products. Compared to the Ctrl group, * p < 0.05, ** p < 0.01. All cell experiments were repeated three times. BRD4, Bromodomain‐containing protein 4; HCP5, HLA Complex P5.

Article Snippet: The acute myeloid leukemia (AML) cell lines Tsuchiya Human Phagocyte‐1 (THP‐1) and Human Leukemia‐60 (HL‐60) (TIB‐202 and CCL‐240, ATCC), along with T‐ALL–specific cell lines Jurkat, CCRF‐CEM, MOLT‐4, and RPMI‐8402 (TIB‐152, CCL‐111, CRL‐1582, and CCL‐27, ATCC), were cultured in RPMI‐1640 medium (11875093, Thermo Fisher Scientific) supplemented with 10% fetal bovine serum (A5670701, Gibco) and maintained in an incubator at 37°C with 5% CO 2 .

(A) CCK‐8 assay measuring cell proliferation in each group at 0, 12, 24, 36, 48, 60, and 72 h, with absorbance detected at OD450. (B) Representative images of Live and Dead staining for each group, with a bar chart depicting the statistical analysis of cell death ratios. Bar = 50 μm. (C) Colony formation assay for each group, with a bar chart showing the statistical analysis of colony numbers. (D) Flow cytometry analysis of apoptosis levels in each group, with a bar chart depicting the statistical analysis of apoptosis rates. Compared with the Ctrl group, * p < 0.05, ** p < 0.01. All cell experiments were repeated three times.
