Recommended: Importance of epigenetics

DNA sequence was the core of genomic research until the emergence of epigenomics where it ‎has been discovered that the surrounding chemical compounds can direct the way the genome ‎functions as a whole. ‎
Given its physical association with genomic material, the epigenome has been suggested to play ‎key roles in regulating genome structure and function, including the timing, strength, and ‎memory of gene expression.1 ‎
Epigenomics has progressed over the past decades and has been hailed as an explanation for ‎inter- and intra-individual diversity, and on the other, as a purveyor of hidden information ‎beyond genes that can be influenced by intrinsic and extrinsic fluctuations. Epigenetic ‎modifications are key to cellular differentiation and help determine cellular identity i.e. what ‎distinguishes a skin cell from a brain or other type of cell.2 ‎
Epigenomic profiling was the key to discov¬ering many significant associations between ‎chromatin features and genomic function at the level of gene regu¬lation and expression, cell ‎identity, ageing and even dis¬ease. 3‎

Conditions including cancers, metabolic disorders, and degenerative disorders have all ‎been found to be related to epigenetic errors. Their alterations have been associated to early ‎stages of cellular transformation in tumors.4 ‎
Epigenomes include histone and DNA modification layered on top of the genome. These are ‎responsible for directing the genome to feed information to genes during particular events. The ‎epigenetic condition of a cell is affected by both developmental and environmental factors, ‎including nutrition, toxins, infection and drugs of abuse. Thus, epigenetics exhibits a close ‎relationship between environment and

    Epigenetics is the word that is used for genes that are modified in order to assist certain genome sequences that lead to diseases and disorders. Epigenetics has come a long way since the first genome sequence had its draft breakthrough in the year 2000 (NOVA 2012). From depression to cancer, epigenetics has made its way through to provide families with the appropriate knowledge and perhaps medication in order to avoid these diseases and disorders in the future.

  • Epigenetics And Cancer Essay

    1972 Words  | 4 Pages

    Cancer is beyond mutations. By definition, epigenetics is the change in gene translation that is caused by alterations not directly due to genetic mutations in the DNA sequence. The 2 main mechanisms are DNA methylation and covalent modification of histones. By methylation, certain molecular tags (methyl groups) bind to a specific sequence of a gene, that results in its disability hence incapable of being translated into its appropriate protein product. These changes affect the cell’s functions leaving its DNA unchanged. Epi is derived from Latin meaning above; hence an epigenetic configuration overlies our genetic predispositions.

    The Genome Project has been an ongoing project sense 1990 and was finally completed on April 14th , 2003. The U.S. Department of Energy and the National Institutes of Health were the ones directing the Genome Project. The progress of the Genome Project is still unknown because the project was completely finished, but scientists are still going to be researching the Genome Project for many years. The project is like a master blue print of the body. The scientists estimated to find about 100,000 genes in the human body but only found as few as 30,000. There are 4 chemical components that make up DNA, cytocine (C), thymine (T), guanine (G), and adenine (A), these 4 components make up who you are. There are a few goals that scientists were trying to reach, such as finding the structure and function of a genome.

    Epigenetics is the science of how the environment influences how our genes are expressed. This article by Aaron Goldberg on science direct explains the nature of epigenetics: the reason Wonder Woman and Superman are different then their present day counterparts is because their genes are being expressed differently (Goldberg, Aaron D. et al.). This is due to our change in environments over the years, where men and women our vocal about many things such as their

  • Epigenetics Essay

    1370 Words  | 3 Pages

    Epigenetics is the study of both heritable and non-heritable changes in gene translation, which do not stem from mutation. Epigenetic alterations to DNA may occur in several different ways; histone modification, DNA methylations, expression of microRNAs, and changes of the chromatin structure (Ntanasis-Stathopoulos et al). Depending on their presentation, they may be passed on to offspring. The exact mechanism of heritable epigenetic modification has not been discovered, but all of these alterations may have some impact on a wide range of disorders and have far reaching implications in the medical field. The study of epigenetics seeks to answer the age old question of whether nature or nurture is responsible for our phenotype, and it has arrived at the answer that in fact, both are. The discovery of epigenetic changes may lead us to cure many disorders, and even personality problems.

    Discoveries in DNA, cell biology, evolution, and biotechnology have been among the major achievements in biology over the past 200 years, with accelerated discoveries and insight’s over the last 50 years. Consider the progress we have made in these areas of human knowledge. Present at least three of the discoveries you find to be the most important and describe their significance to society, health, and the culture of modern life. DNA (deoxyribonucleic acid) is a self-replicating molecule or material present in nearly all living organisms as the main constituent in chromosomes. It encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses.

  • Gene Expression in Eukaryotes

    Distinct characteristics are not only an end result of the DNA sequence but also of the cell’s internal system of expression orchestrated by different proteins and RNAs present at a given time. DNA encodes for many possible characteristics, but different types of RNA aided by specialized proteins sometimes with external signals express the needed genes. Control of gene expression is of vital importance for an eukaryote’s survival such as the ability of switching genes on/off in accordance with the changes in the environment (Campbell and Reece, 2008). Of a cell’s entire genome, only 15% will be expressed, and in multicellular organisms the genes active will vary according to their specialization. (Fletcher, Ivor & Winter, 2007).

  • Decoding Epigenetics: The Impact of Lifestyle on Genes

    1063 Words  | 3 Pages

    This asserts that like certain genetic factors are undoubtedly inherited through generations, epigenetic factors also have trans generational effects on our genetic predispositions. As discussed previously, epigenetic factors are subject to environmental changes. This means that despite their original genetic makeup, your ancestors’ environmental choices (for example smoking, diet and exercise, and lifestyle) also have a direct effect on your genetic makeup, as the changes caused by their lifestyle choices affect the chemical tags your epigenes turn on and off. This is interesting hen one examines their family history of disease. At its most basic, the study of epigenetics suggests that a simple family history workup should tell you relatively what major diseases you might be at genetic risk of developing. In light of my personal family history, the only obvious disease risk factors appear to be cancer in three grandparents and thyroid disease in five family members: one being a parent, another a grandparent, two aunts, and a cousin, all on the maternal side of the family. Based on the ideal promise of epigenetics, one might hope that scientific research might discover either a way to change environmental factors such as diet in a way that would cause epigenetic mechanisms to shut off the genetic markers in my makeup that might carry cancer and thyroid disease.

    I investigated the roles of the histone variant H3.3 during oocyte-to-egg transition. I reveal that H3.3 mediates a balance between open and condensed chromatin that is crucial for the fidelity of chromosome segregation during early mouse development. Knocking down of H3.3 in fertilised mouse zygotes leads to developmental arrest at the morula stage. Loss of H3.3 leads to over-condensation and mis-segregation of chromosomes with corresponding high levels of aneuploidy. H3.3-deficient embryos have significantly reduced levels of markers of open chromatin, such as H3K36me2 and H4K16Ac.
