Liquid biopsy epigenetics: establishing a molecular profile based on cell‐free DNA
Molecular Oncology, EarlyView.Cell‐free DNA (cfDNA) fragments in plasma from cancer patients carry epigenetic signatures reflecting their cells of origin. These epigenetic features include DNA methylation, nucleosome modifications, and variations in fragmentation. This review describes the biological properties of each feature and explores optimal strategies for harnessing cfDNA ...

CA: A Cancer Journal for Clinicians, 2010 Epigenetics refers to stable alterations in gene expression with no underlying modifications in the genetic sequence and is best exemplified by differentiation, in which multiple cell types diverge physiologically despite a common genetic code. Interest in this area of science has grown over the past decades, especially since it was found to play a ...

Epigenetic profiling to environmental stressors in model and non-model organisms: Ecotoxicology perspective [PDF]
Environmental Health and Toxicology, 2018 Epigenetics, potentially heritable changes in genome function that occur without alterations to DNA sequence, is an important but understudied component of ecotoxicology studies.

Journal of Cellular Physiology, 2009 AbstractEpigenetics refers to mitotically and/or meiotically heritable variations in gene expression that are not caused by changes in DNA sequence. Epigenetic mechanisms regulate all biological processes from conception to death, including genome reprogramming during early embryogenesis and gametogenesis, cell differentiation and maintenance of a ...

DNA methylation at the DAT promoter and risk for psychopathology. Intergenerational transmission between school-age youths and their parents in a community sample [PDF]
, 2018 Background: The effect of gene polymorphisms and promoter methylation, associated with maladaptive developmental outcomes, vary depending on environmental factors (e.g., parental psychopathology).

The Impact of Nutrition and Environmental Epigenetics on Human Health and Disease
International Journal of Molecular Sciences, 2018 Environmental epigenetics describes how environmental factors affect cellular epigenetics and, hence, human health. Epigenetic marks alter the spatial conformation of chromatin to regulate gene expression.

Molecular Oncology, EarlyView.Clinical trials on PARP inhibitors in urothelial carcinoma (UC) showed limited efficacy and a lack of predictive biomarkers. We propose SLFN5, SLFN11, and OAS1 as UC‐specific response predictors. We suggest Talazoparib as the better PARP inhibitor for UC than Olaparib.

ILAR Journal, 2012 Within the last two decades, significant progress has been made in understanding the importance of epigenetic mechanisms in the regulation of gene expression as a consequence of gene-environment interactions. Nutrition, among many other environmental factors, is a key player that can induce epigenetic changes not only in the directly exposed organisms ...

DNA methylation dynamics in aging: How far are we from understanding the mechanisms? [PDF]
, 2018 DNA methylation is currently the most promising molecular marker for monitoring aging and predicting life expectancy. However, the mechanisms underlying age-related DNA methylation changes remain mostly undiscovered.Here we discuss the current knowledge ...
