The importance of epigenetic modifications in cancer progression
Epigenetics are dynamic and inherited changes in the genome that occur independently of DNA sequencing. This phenomenon requires coherent interaction with various enzymes and other molecular components. Abnormal epigenetic changes can lead to the onset of improper gene expression and the promotion of tumorigenesis. Because epigenetic changes are prone to external and reversible factors, they ar...
متن کاملToti-/pluripotential stem cells and epigenetic modifications.
The recent fascinating breakthrough in the area of stem cell research is the successful production of cloned animals via nuclear transplantation of somatic nucleus by intrinsic trans-acting factors of oocytes and trans-differentiation of somatic stem cells from adult organs induced by extrinsic growth factors. During the process of nuclear reprogramming, epigenetic modification of the somatic n...
متن کاملEpigenetic modifications in cancer.
Cancer initiation and progression is controlled by both genetic and epigenetic events. The complexity of carcinogenesis cannot be accounted for by genetic alterations alone but also involves epigenetic changes. Epigenetics refers to the study of mechanisms that alter gene expression without altering the primary DNA sequence. Epigenetic mechanisms are heritable and reversible, and include change...
متن کاملAsthma Discordance in Twins Is Linked to Epigenetic Modifications of T Cells
T cells mediate the inflammatory responses observed in asthma among genetically susceptible individuals and have been suspected to be prone to epigenetic regulation. However, these relationships are not well established from past clinical studies that have had limited capacity to control for the effects of variable genetic predisposition and early environmental exposures. Relying on a cohort of...
متن کاملEpigenetic Modifications of Host Genes Induced by Bacterial Infection
Introduction: Epigenetic mechanisms regulate expression of the genome to generate various cell types during development or coordinate cellular responses to external stimulus. While epigenetics is of fundamental importance in eukaryotes, it plays a different role in bacteria. This article uncovers the most important recent data on how bacteria can alter epigenetic marks and can also contribute t...
