The rapid evolution of pluripotency-associated SEs in mammals. (A) Numbers of human, pig, and mouse pluripotency-associated SEs and TEs. (B) SE- and TE-linked genes of humans (red), pigs (blue), and mice (green). (C) GO analysis of the shared enhancer-linked genes in three species. (D) Phylogenetic analysis of the SE sequences of humans, pigs, and mice. The H3K27ac, OCT4, and SOX2 ChIP-defined SEs in porcine PSCs were identified and subjected to conservation analysis in the genomes of humans and mice. The SE-linked genes are listed. (E and F) Characteristics of the SE linked to the gene TEX14 (SE-TEX14) in pigs. SE-TEX14 shows different proximal genes in humans and mice and displays high OCT4 occupation. h, human; m, mouse; p, pig.
