Extended Data Fig. 3: Enhanced expression of luminal differentiation-related genes is associated with increased H3K27 acetylation at nearby super-enhancers.

a, Representative H3K27ac ChIP-seq genome browser tracks with co-localized H3K27ac-decorated genomic loops (HiChIP) in MCF7 cells treated with DMSO or abemaciclib for 7 days. Gene promoters are highlighted in grey. b, Relative RNA-seq normalized reads of genes in MCF7 shRB1 cells treated with DMSO or abemaciclib for 7 days (n=2 independent cultures). c, Relative mRNA expression of genes shown in Fig. 3d in MMTV-rtTA/tetO-Her2 tumors treated for up to 59 days with vehicle or abemaciclib (n=3 independent tumors). Means ± s.d. are shown. P-values were determined by two-tailed unpaired t-tests corrected for multiple comparisons by Holm-Sidak method.
