From: Origin, evolution, and tissue-specific functions of the porcine repetitive element 1
Proximal PRE1 as a cis-regulatory element. a Differentially-methylated PRE1 and H3K27ac signals in the promoter of the TCEA3 gene. b–d Epigenetic and expressed signals in the TCEA3, HACD3 and HORMAD1 genes. e, f Number of PRE1 and differentially methylated PRE1 copies in intragenic, proximal, and distal regions. Proximal PRE1 and distal PRE1 were defined as those that are 1 to 2 kb and 2 to 100 kb upstream of their flanking genes, respectively
