eBook: DNA Methylation 2024May 15, 2024DNA methylation, whether in cells or in a cell-free environment, is one of the most powerful and most studied epigenetic regulators of gene expression and genomic organization. This is true for nearly all organisms, leading to the emergence of numerous methods for mapping 5-mC and 5-hmC and other modification states. There are many approaches for […]
Pregnancy Epigenetically Ages Mothers – But Breastfeeding May Reverse ItApril 22, 2024Our mothers might be onto something when they jokingly blame us for their gray hair and wrinkles. In two recent studies, DNA methylation-based epigenetic clocks show that pregnancy, with its far-ranging emotional and physical changes, increases the biological ages of mothers. On the bright side, the effects were reversible in those who breastfed, according to […]
A Selfish, Poisonous Element Could Set the Evolutionary Stage for Genomic ImprintingApril 15, 2024A selfish toddler might throw a tantrum to get their way, but in worms, a “selfish” piece of DNA known as a toxin-antidote (TA) element uses something more sinister—poison. Researchers have just discovered a parent-of-origin effect with this nematode element that could be an evolutionary precursor of genomic imprinting. Led by Alejandro Burga (Institute of Molecular […]
EvoETR Epigenome Editor Helps Maintain Cholesterol Levels by Silencing Pcsk9March 25, 2024Ever wanted to cut a bad thing out of your life? Well, perhaps the secret to success doesn’t involve any cutting (of your DNA). In some people, a mutant PCSK9 gene interferes with the liver’s job to get rid of LDL, aka “bad” cholesterol. Now, researchers have developed an all-in-one “evolved engineered transcriptional repressor” (EvoETR) […]
No Epigenetic Modification is an Island: How Reader Proteins Functionally Interpret Complex Chromatin StatesMarch 25, 2024Like no man is an island and instead relies on those surrounding them, single epigenetic modifications generally do not function in solitary. Now, an absorbing new study from a synergistic epigenomics squad reports how epigenetic reader proteins functionally interpret chromatin states made up of complex combinations of disparate epigenetic modifications. A highly collaborative team guided […]
