Epigenetics Product Range Expanded
March 28, 2013 11:39 am | Product Releases | Comments
Porvair Sciences has announced the addition of the novel Chromatrap chromatin immunoprecipitation (ChIP) assay range to its portfolio of products for epigenetics. Developed in conjunction with Department of Life Sciences at University of Swansea, UK, Chromatrap uses a solid phase porous polymer functionalized with protein A, allowing the chromatin capture to be more efficient than bead based methods.
Epigenetics Can Predict Postpartum Depression
May 21, 2013 10:04 am | News | CommentsResearchers say they have discovered specific chemical alterations in two genes that, when present during pregnancy, reliably predict whether a woman will develop postpartum depression. The epigenetic modifications, which alter the way genes function without changing the underlying DNA sequence, can apparently be detected in the blood of pregnant women during any trimester.
Stem Cell Epigenomics Mimic Early Human Development
May 10, 2013 9:59 am | News | CommentsScientists have long known that control mechanisms known collectively as "epigenetics" play a critical role in human development, but they did not know precisely how alterations in this extra layer of biochemical instructions in DNA contribute to development.
Epigenetic Factor Can Control Carcinoma Spread
May 9, 2013 10:31 am | News | CommentsVery little has been known about the epigenetic events that occur prior to the invasive growth of head and neck squamous cell carcinomas and their spread to other parts of the body, or metastasis. Researchers discovered what could be a crucial step toward understanding the process that activates the cancer cells.
Epigenetic Changes Shed Light on Autism
April 23, 2013 1:13 pm | News | CommentsScientists have identified patterns of epigenetic changes involved in autism spectrum disorder (ASD) by studying genetically identical twins who differ in autism traits. The study is the largest of its kind and may shed light on the biological mechanism by which environmental influences regulate the activity of certain genes and in turn contribute to the development of ASD and related behavior traits.
Junk DNA Isn’t Really Junk
April 16, 2013 12:24 pm | News | CommentsSpecific DNA once dismissed as junk plays an important role in brain development and might be involved in several devastating neurological diseases, scientists have found. Their discovery in mice is likely to further fuel a recent scramble by researchers to identify roles for long-neglected bits of DNA within the genomes of mice and humans alike.
Epigenetics Discovered in Corn Inheritance Behavior
March 27, 2013 10:37 am | News | CommentsNew research explains how certain traits can pass down from one generation to the next– at least in plants– without following the accepted rules of genetics.
Epigenetics Mechanism Links Mom's Nutrition to Child's Health
March 12, 2013 9:22 am | News | CommentsStudies by U. S. Department of Agriculture-funded research molecular geneticist Robert A. Waterland are helping explain how the foods that soon-to-be-moms eat in the days and weeks around the time of conception—or what's known as periconceptional nutrition—may affect the way genes function in her children, and her children's health.
