a, Gene Ontology analysis of interferon-related signatures using genes predicted to be regulated by all abemaciclib-activated enhancers, abemaciclib-activated SEs, or abemaciclib-activated LTR enhancers in MCF7 cells treated with DMSO or abemaciclib for 7 days. Odds ratios and P-values calculated by ChIP-Enrich.
b, ATAC-seq and H3K27ac ChIP-seq tracks near representative immune genes in MCF7 and MDA-MB-453 treated with DMSO or abemaciclib for 7 days. LTRs annotated using Repeat Masker are shown as blue bars. Yellow highlights indicate H3K27ac up-peaks that align with an LTR.
c, Relative RNA-seq normalized reads of immune genes in MCF7 parental and shRB1 cells treated with DMSO or abemaciclib for 7 days, measured by RNA-seq (parental: n=3; shRB1: n=2). Means ± s.d. are shown. DESeq2 was used to calculated adjusted P-values.
