Epigenetics & Chromatin is a peer-reviewed open access scientific journal that publishes research related to epigenetic inheritance and chromatin-based interactions. First published in 2008 by BioMed Central, its overall aim is to understand the regulation of gene and chromosomal elements during the processes of cell division, cell differentiation, and any alterations in the environment.
Epigenetic mechanisms. In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi-(ἐπι-"over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of inheritance. [2]
Paternal stress is an important factor in the determination of inheritance of genes as well as maternal stress inheritance. Factors such as environment and experiences can alter the epigenetic of paternal genes as well as in sperm. Epigenetic changes to the DNA in sperm ("epigenetic tags") prior to conception can be passed to offspring.
The function of DNA strands (yellow) alters depending on how it is organized around histones (blue) that can be methylated (green).. In biology, the epigenome of an organism is the collection of chemical changes to its DNA and histone proteins that affects when, where, and how the DNA is expressed; these changes can be passed down to an organism's offspring via transgenerational epigenetic ...
By remodeling chromatin structure and changing the density of DNA packaging, gene expression can thus be modulated. [14] Chromatin remodeling occurs via post-translational modifications of the N-terminal tails of core histone proteins. [16] The collective set of histone modifications in a given cell is known as the histone code.
Epigenetics is a monthly peer-reviewed scientific journal covering research pertaining to epigenetics. It was established in 2006 and published by Landes Bioscience, until this company was acquired by Taylor & Francis in 2014. It is the official journal of the Epigenetics Society (formerly the DNA Methylation Society
Epigenetics of human development is the study of how epigenetics (hertiable characteristics that do not involve changes in DNA sequence) effects human development. Development before birth, including gametogenesis , embryogenesis , and fetal development , is the process of body development from the gametes are formed to eventually combine into ...
Epigenetic instability caused by deregulation in chromatin remodeling is studied in several cancers, including breast cancer, colorectal cancer, pancreatic cancer. Such instability largely cause widespread silencing of genes with primary impact on tumor-suppressor genes.
