- Aberrant methylation of DNA has been recognized as common epigenetic changes in human cancer. DNA異常甲基化是腫瘤常見的表觀遺傳學改變。
- Epigenetic changes are heritable changes to the regulation of a cell's genes, caused by extra molecules being attached to those genes. 即便最近對代際遺傳現象的觀察也顯示:這一現象初看起來像是獲得性遺傳(這是達爾文派的一個禁忌),但可能並非如此。

- Over the years, our laboratory has found that Zizania DNA introgression could induce a large number of genetic and epigenetic changes in some introgression lines. 我們實驗室的前期工作發現將菰的基因組DNA導入水稻中能誘導水稻基因組獲得漸滲雜交系發生廣泛的基因組變異和表觀遺傳變異。
- DNA methylation is the best studied of the epigenetic changes that influence the gene expression,and changes in genomic methylation patterns have been observed in many cancer cell lines. DNA甲基化是目前研究最為深入的表觀遺傳學機制,在腫瘤細胞中基因組甲基化模式常常發生改變;
- According to Perera, some evidence already exists that PAHs can lead to epigenetic changes in gene activity that cannot be identified by looking for breaks or disruptions in the genetic code itself. 裴里拉說,已經有些證據指出PAH所導致的基因活動產生外遺傳變化,這些變化中並沒發現有基因編碼的缺失與改變。
- Genomic imprinting is a type of epigenetic change that causes one copy of a particular gene to be turned off, depending on its parental origin. 「基因組印跡」屬於後生變化之一,它能夠關閉來自其親本的某一特定基因的複製。
