WitrynaIn animals, piRNAs and their associated Piwi proteins guard germ cell genomes against mobile genetic elements via an RNAi-like mechanism. In Caenorhabditis elegans, 21U-RNAs comprise the piRNA class, and these collaborate with 22G RNAs via unclear mechanisms to discriminate self from nonself and selectively and heritably silence … Witryna13 lut 2003 · Epigenetics in Reproductive Medicine.

Witrynaheritable: [adjective] capable of being inherited or of passing by inheritance. WitrynaThus the same gene, with the same primary DNA sequence, can be kept heritably ‘on' across numerous cell divisions in one cell and be kept heritably ‘off' across numerous cell divisions in a nearby cell. This differential heritable regulation of the same gene, frequently referred to as epigenetic regulation, occurs at least in part by ... bar en sala

WitrynaAberrant DNA methylation in the regulatory region of cancer-associated genes has now been established as an alternative mechanism to heritably silence gene transcription. 肿瘤相关基因调控区的 异常 DNA 甲基化 现已被确立为除遗传突变以外的另一个可遗传的基因转录沉默的发生机制。 WitrynaEpigenetics includes many ways gene expression can be heritably altered. One way is through the addition of a molecule called a methyl group to cytosine, one of the four bases of DNA. When a section of DNA is methylated, the cell’s transcription machinery reads the DNA differently and some genes are effectively silenced. Such epigenetic ...
