An Epigenetic Link Between Memory Loss and Epilepsy

June 30, 2015 Bailey Kirkpatrick

Researchers at the University of Alabama at Birmingham have discovered a potential epigenetic explanation for why individuals with epilepsy, particularly temporal lobe epilepsy, usually experience memory loss. They even propose a way to undo that loss of memory. Published recently in the Annals of Translational and Clinical Neurology, a group of UAB scientists believes their results could progress our understanding of numerous other disorders involving memory loss and could lead to a therapeutic approach for restoring proper memory function via [more…]

DNA Methylation, Melting DNA, and Twins: Advancing Forensic Investigations

June 23, 2015 Bailey Kirkpatrick

DNA profiling, also known as genetic fingerprinting has been crucial to the forensic investigation of crime scenes since the 1980s. Although important to the success of many cases, this technique comes with some limitations, particularly when investigators are trying to match DNA evidence to a twin. Using this method, it is difficult to conclusively determine which twin may be innocent and which may be guilty because of their identical DNA sequence. Scientists at the University of Huddersfield, however, conducted research [more…]

The Epigenetics of Father’s Day: 3 Little Known Reasons to Thank Your Dad

June 16, 2015 Bailey Kirkpatrick

Along with Father’s Day comes the typical thank-yous, the gratitude that never quite seems to be enough for the love Dad has shown for all the years. Maybe your father encouraged you through difficult times or supported you when you needed it most. These are wonderful things to thank your dad for, but there might be something you’ve been missing all along. Have you ever thought of thanking him for being an epigenetic hero? Your dad’s behavior and experiences may [more…]

Bisulfite Sequencing of Ancient DNA May Lead to Clues about Old Populations

June 9, 2015 Bailey Kirkpatrick

For the first time, anthropologists from The University of Texas at Austin have shown that epigenetic tags on DNA, such as DNA methylation, can be successfully detected in the remains of ancient human DNA using bisulfite sequencing. These results can help progress future studies to enhance our understanding of disease and famine experienced by those from ancient times. Epigenetic research assesses various chemical marks made to DNA which do not alter the underlying genetic code, but impact how certain genes [more…]

DNA Methylation Gives Epigenetic Hope to Cocaine Addiction Treatment

June 2, 2015 Bailey Kirkpatrick

Not only is cocaine a highly addictive drug, but it also comes with an incredibly high chance of relapse even after someone has abstained and experienced symptoms of withdrawal. A new study is illuminating the epigenetic changes made to DNA during the withdrawal stage for those trying to rid themselves of the drug and offers new hope for more effective epigenetic-based treatments for drug addiction. According to researchers from McGill University and Bar Ilan University, the genes found in your [more…]
