Table 1 Number of differentially methylated probes sorted by genomic region

From: Variable promoter methylation contributes to differential expression of key genes in human placenta-derived venous and arterial endothelial cells

 

All probes

Probes located within 1500 bp upstream, 5'UTR and 1st Exon (“non‒gene body” probes)

  1. Q1, probes showing less methylation (<-10%) and higher expression (>0.5 LogFC); Q2, probes showing higher methylation (>10%) and expression; Q3, probes showing higher methylation and less expression (<-0.5 LogFC); Q4, probes showing less methylation and expression in HPAEC relative to HPVEC, Genomic regions may overlap between one or more categories (e.g. a probe can be located in 1500 bp from upstream and also be associated with Enhancer and/or Promoter).
