doi: 10.1101/2025.04.23.650343
Figure Lengend Snippet: (A) Table showing the number of genes with proximal or anchored ESR1 binding (identified through integration of H3K27ac vehicle HiChIP and ESR1 Cut&Run), as well as overlap with 369 genes regulated by ESR1/E2 in engineered THESC (E2-dependent DEGs). (B) Select pathways from metascape pathway analysis of 75 genes regulated by ESR1/E2 with proximal or anchored ESR1 binding at the promoter. (C) Bar chart comparing RNA-seq log2CPM normalized counts for ERRFI1, NRIP1, and EPAS1 in THESC ESR1 treated with E2 or vehicle for 24 hours. Error bars are shown as mean with SEM. (D) UCSC genome browser views around the ERRFI1, NRIP1, and EPAS1 loci. Tracks show ESR1 Cut&Run in THESC ESR1 treated with E2 for 3 hours, with IgG background subtracted (black), H3K27ac Cut&Run in THESC (red), and H3K27ac HiChIP loops in vehicle treated hESC (blue). The promoter of the gene of interest is highlighted in pink, ESR1 binding peaks are highlighted in blue, and the HiChIP loop that connects the gene promoter with the ESR1 binding peak is highlighted with a blue loop. (E) Cell viability assessed by MTT assay in THESC ESR1 and THESC NT treated with vehicle or E2 for 4 days. Statistical significance was determined by one-way ANOVA with significance defined as p-value < 0.05. Error bars are shown as mean with SEM. (F) Microscopic images and quantification of density of migrated THESC ESR1 and THESC NT treated with vehicle or E2 for 72 hours. Cells were stained with 1% crystal violet solution, and cell density was quantified using ImageJ. Statistical significance was determined by one-way ANOVA with significance defined as p-value < 0.05. Error bars are shown as mean with SEM. THESC = immortalized human endometrial stromal cells; THESC ESR1 = ESR1 activated cells; SEM = standard error of the mean; THESC NT = control non-targeting cells; E2 = 10 nM estradiol; vehicle = 0.1% ethanol; EPC = 10 nM E2, 1 uM medroxyprogesterone acetate, and 100 uM cAMP; CPM = counts per million; SEM = standard error of the mean.
Article Snippet: Telomerase-transformed human endometrial stromal cells, THESC ( ) (ATCC, CRL-4003), were maintained in DMEM/F-12 (Gibco Thermo Fisher Scientific, Waltham, MA, USA) supplemented with 10% Fetal Bovine Serum (FBS, Gibco Thermo Fisher Scientific) and antibiotics (10 000 IU/mL penicillin, 10 000 IU/ mL streptomycin; Life Technologies, Grand Island, NY, USA), termed regular hESC media.
