Moms Exposed to Lead May Impact DNA Methylation of Her Children and Grandchildren

November 24, 2015 Bailey Kirkpatrick

Evidence supporting multigenerational epigenetic inheritance continues to mount as a group of researchers discover that mothers who have a significant amount of lead present in their blood can epigenetically impact not only their unborn children, but their grandchildren as well. The study was published in Scientific Reports. It is well known that children in the womb can be impacted by small amounts of exposure to lead. If a woman is pregnant and exposed to lead, it can harm the baby [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…]

Could Epigenetics Explain the Origins of Allergic Disease?

March 24, 2015 Natalie Crowley

Finally, spring is here – that wonderful time of year when the temperature starts to rise and everything is in bloom. But for many of us, it also marks the beginning of allergy season. That means itchy watery eyes, sneezing, running nose, coughing and overall misery. But allergies don’t just affect people in the spring and they are not all related to weather. According to the Centers for Disease Control and Prevention (1), more than 50 million Americans have an allergy [more…]

The Epigenetics Lurking in Your Halloween Candy

October 29, 2014 Bailey Kirkpatrick

Halloween marks the joyous time to carve pumpkins, dress up in frightening garb, and – most importantly – gorge ourselves on sugary candies that seem to be in never-ending supply. It seems harmless enough to snack on some candy corn and taffy and Milk Duds and Twizzlers and… well, you get the idea. Treating yourself to “just a little” candy on Halloween doesn’t seem very harmless, but do you know the epigenetic power that might be lurking in your Halloween [more…]

Inheritance and Transmission of Epigenetic Memory Across Generations

September 30, 2014 Bailey Kirkpatrick

New research has been suggesting that parents can transmit changes to their gene expression to their children. The heritable changes occur as a result of environmental stresses and are known as epigenetic modifications. A previous article covered the epigenetic transfer of nutrition “memory” across several generations. Now, a recent study by researchers from the University of California in Santa Cruz, demonstrates the transferring of epigenetic memory across generations as well as from one cell to another during early development. The [more…]

Epigenetic Transfer of Nutrition ‘Memory’ Ends before Great-Grandchildren

July 17, 2014 Bailey Kirkpatrick

A child is at an increased risk for developing type 2 diabetes and obesity if his or her mother was undernourished during pregnancy. This risk is caused in part by epigenetic changes thought to persist through generations, but it’s uncertain at which generation these changes stop affecting offspring. Researchers at University of Cambridge give us insight into the temporality of this epigenetic “memory” of nutrition using a mouse model and demonstrate its persistence in mice sperm. In a study published [more…]
