Epigenetic Editing Approach Causally Connects Adolescent Alcohol Exposure to Psychiatric Disorder RiskMay 23, 2022The modularity of current epigenetic editing technology allows us to evaluate the causality of connections from multiple angles. Now, epigenetic editing in rats using dCas9 activators and repressors has provided a welcome new perspective on how adolescent drinking can induce the onset of psychiatric conditions in adults. Binge drinking during adolescence (a critical period for […]
An Oliver’s Twist on an Old Tale: Orphan CpGs Will Have You Asking for MoreJuly 17, 2021Move over Oliver Twist, there’s a new orphan in town to satisfy our hunger for stories of DNA methylation. Two new tales of orphan CpGs help them find a home in our hearts and epigenomes through the application of cutting-edge epigenomics techniques and genetic engineering to embryonic stem cells and neuronal cells. Making the Right Connections: […]
It’s Nature versus Nurture in an Epigenetic Rejuvenation Face-off!July 15, 2021The age-old battle of nature versus nurture has entered new frontiers with two exciting studies exploring different mechanisms that drive “epigenetic rejuvenation” – also known as the science of how our old and creaky DNA methylation-based epigenetic clocks can be wound back into a frolicking and fancy-free state. Together, these studies demonstrate the two faces […]
Diet Adds a Tasty New Plot Twist in The Tale of Paternal H3K4me3 TransmissionMarch 2, 2021The genetic tale of transgenerational epigenetic inheritance has just received a tasty twist in its latest installment focused on intergenerational effects. The latest story of this cereal … serial reveals how folate deficiency in the paternal diet influences embryonic development through H3K4me3 transmission. In a previous study, the lab of Sarah Kimmins (McGill University, Montreal, Canada) examined a mouse […]
