Maternal Smoking Epigenetically Harms Child Development
…mother’s child. Epigenetics is a field of research that has recently gained significant momentum in the scientific community and popular culture alike. Various chemical modifications, such as DNA methylation or…
The Precise Power of CRISPR/Cas9 System Creates Exciting Opportunities for Genetic and Epigenetic Editing
…as DNA methylation or histone modification – of specific DNA sites. Once researchers were able to demonstrate the success of this system in other cells as well as bacteria, Niles…
Researchers Modify CRISPR/Cas9 System to Target Epigenetics and Reverse Diseases
…editing DNA methylation using CRISPR/Cas9 and targeting chromatin modifications using Cas9. Read An Introduction to Understanding the CRISPR/Cas9 System, the technology that allows researchers to edit and influence gene expression….
RNA-Methylation-Dependent RNA Processing Controls the Speed of the Circadian Clock
…methylation potential is disrupted. m6A methylation regulates the nuclear processing of mRNA. Circadian clock genes have multiple m6A methylation sites. Therefore, lack of m6A-RNA methylation causes a delay in RNA…
Conserved, Widespread, Dynamic mRNA Methylation Program in Yeast Meiosis Revealed by High-Resolution Mapping
…methylation maps at nearly single-nucleotide resolution. Their studies also identified several similarities between mRNA methylation in yeast and mammals, thereby confirming that yeast is a relevant model for m6A methylation…
Epigenetics May Be Involved in Noise-Induced Hearing Loss
…long-term exposure the gene Comt methylation was increased in the inferior colliculus, LINE-1 methylation was increased in the medulla oblongata and the gene Mc2R methylation was decreased in the hippocampus….
A Mother’s Behavior Could Epigenetically Impact Infant Oxytocin Levels
…infant behaviors. Specifically, the researchers focused on DNA methylation levels in the infants, and how they changed depending on the mother’s involvement in play. DNA methylation is an epigenetic mechanism…
A Stimulating Environment May Prevent The Brain From Epigenetically Aging
…environmental enrichment (ENR) had on the epigenetic signature of the brain. What they found was that ENR counteracted aging-induced DNA methylation alterations at genes associated with neuronal plasticity and adult…
Arthritic Joints May Need Different Treatments Due to Diverse Epigenetic Signatures
…The DNA methylation marks in the specialized cells lining the joints were significantly different in RA than in OA. DNA methylation is a well-known epigenetic mechanism that can impact gene…
