ESR1 ChIPseq of proliferative and mid-secretory endometrial biopsies. A, Venn diagram comparing number of ESR1 peaks in one proliferative (Prolif) endometrial biopsy to ESR1 peaks in one mid-secretory (MS) endometrial biopsy. B, Locations of ESR1 peaks from proliferative or mid-secretory endometrium or from organoids, relative to annotated genes (RefSeq). C, Summaries of the top 15 HOMER known motifs enriched in ESR1 peaks from proliferative or mid-secretory endometrial biopsies. The ranks of each motif, as determined by P value, along with the range of P values covered by the ranks are indicated. Motif logos are shown.
