表观遗传改变不同于基因突变引起DNA序列的永久改变,它不改变基因编码序列。表观遗传调节诱导DNA双螺旋结构的改变和调节基因编码序列上游启动子区域转录因子的进入。表观遗传调节形式包括组织特异的DNA甲基化,组蛋白修饰,microRNA的调节。肿瘤是由遗传和表观遗传渐进性异常所致的一种疾病,该模式可被影响到基因转录的特定启动子状态改变和染色体结构整体改变所映证。表观遗传学在骨肉瘤发生发展过程中作用增加
Epigenetic changes, unlike genetic mutations, result in a permanent change in DNA sequence that does not alter the gene coding sequence. Epigenetic regulation induces changes in the DNA double helix structure and regulates the entry of transcription factors upstream of the promoter region of the gene coding sequence. Epigenetic modalities include tissue-specific DNA methylation, histone modification, and regulation of microRNAs. Tumors are a disease caused by inherited and epigenetic progressive abnormalities that can be reflected by changes in the state of a particular promoter and overall structural changes in the chromosome that affect transcription. Epigenetics increases the development of osteosarcoma
