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].当突变型胚胎干细胞（Embryonic Stem Cell, ES）系或睾丸中的重复序列元件表达出现统计学显著上调与下调时，分别以向上箭头与向下箭头标注。仅对某一重复序列元件的少量探针产生影响的表达变化，以方括号标注。上述元件的基因表达变化幅度详见正文。 *尽管本研究中DNA甲基转移酶三重敲除（DNA methyltransferase Triple Knockout, Dnmt TKO）ES细胞的微阵列（microarray）数据未检测到MMERVK10C的表达变化，但RNA测序（RNA Sequencing, RNA-seq）分析显示，Dnmt TKO ES细胞中部分MMERVK10C基因组拷贝存在上调现象[22]。
