Web15 de jun. de 2024 · Gene regulatory information can be inherited between generations in a phenomenon termed transgenerational epigenetic inheritance (TEI). While examples of TEI in many animals accumulate, the nematode Caenorhabditis elegans has proven particularly useful in investigating the underlying molecular mechanisms of this phenomenon. In C. … Web28 de mar. de 2024 · Background: Multicellular organisms require precise gene regulation during ontogeny, and epigenetic modifications, such as DNA methylation and histone modification, facilitate this precise regulation. The conservative reprogramming patterns of DNA methylation in vertebrates have been well described. However, knowledge of how …

Web15 de set. de 2016 · How histone modifications are inherited and reprogrammed in this process is a long-standing puzzle. Using a highly sensitive ChIP-seq approach, we investigated genome-wide reprogramming of H3K27me3 across a total of 14 mouse developmental stages. WebHistone modifications act in diverse biological processes such as transcriptional activation/inactivation, chromosome packaging, and DNA damage/repair. In most species, histone H3 is primarily acetylated at lysines 9, 14, 18, 23, and 56, methylated at arginine 2 and lysines 4, 9, 27, 36, and 79, and phosphorylated at ser10, ser28, Thr3, and Thr11. Web7 de nov. de 2024 · Epigenetics is the epi-information beyond the DNA sequence that can be inherited from parents to offspring. From years of studies, people have found that histone modifications, DNA methylation, and RNA-based mechanism are the main means of epigenetic control.
