Summary of changes in repetitive element expression detected by microarray repeat-annotation in this study.

Statistically significant upregulation and downregulation of repetitive element expression in mutant ES cell lines or testes is indicated by up and down arrows respectively. Changes that only appear to affect a small number of probes for a repetitive element are indicated in brackets. The degree of change in gene expression detected for these elements is detailed in the main text.*Although changes in MMERVK10C expression were not detected in Dnmt TKO ES cell microrray data in this study, RNA-seq analysis suggests that some genomic copies of MMERVK10C are upregulated in Dnmt TKO ES cells [22].
