LPS effects on DNA methylation in bovine endometrial epithelial cells (bEECs). a Principal component analysis displaying overall methylation profiles across all samples. The first dimension explained 21% variation and separated Cow1 from Cow2 and Cow3. The second dimension explained 16% variation, separated both Cow2 versus Cow3. b Venn diagram displaying overlapping differentially methylated regions (DMRs) from 24 h sample groups: 0 μg vs. 2 μg (pink), 0 μg vs. 8 μg (blue), and 0 μg vs. 2 μg + 8 μg (green). c Heatmap of significant DMRs (1291) showing similar methylation trend for the analyses performed in (b). The scale shows hypermethylated (red) and hypomethylated (blue) levels for each DMR. d Bar plot showing distribution of the percent of hyper and hypomethylated DMRs when comparing time 0 h and 24 h in controls, and 24 h control with 2 μg or 8 μg, and 2 μg + 8 μg combined LPS groups. Top bar shows a similar pattern for total DMRs identified in 2 μg, 8 μg, and 2 μg + 8 μg analysis
