About Bailey Kirkpatrick
Bailey Kirkpatrick is a science writer with a background in epigenetics and psychology with a passion for conveying scientific concepts to the wider community. She enjoys speculating about the implications of epigenetics and how it might impact our perception of wellbeing and the development of novel preventative strategies. When she’s not combing through research articles, she also enjoys discovering new foods, taking nighttime strolls, and discussing current events over a barrel-aged sour beer or cold-brewed coffee.

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…]

Smoking Linked to Epigenetic Warning Signs of Cancer in Cheek Cells

May 26, 2015 Bailey Kirkpatrick

New research published in JAMA Oncology shows that DNA damage that occurs as a result of smoking may be found in cheek swabs. In light of this research, smoking is thought to adjust the epigenetic profile of cheek cells and the resulting epigenetic landscape may even be used as an early warning sign of other cancers typically unrelated to smoking, such as gynecological and breast cancers. Professor Martin Widschwendter, Head of the Department of Women’s Cancer at the UCL Institute [more…]

3 Epigenetic Reasons to Meditate Your Stress Away

May 19, 2015 Bailey Kirkpatrick

Feeling stressed? You’re not alone. According to the American Psychological Association, people are living with stress at levels higher than what is considered healthy. Unsurprisingly, the APA found the top four sources of stress to be money, work, family responsibilities, and health concerns. Are you nervous about that project that’s due this week? Worried about the last of your sample that’s incubating in the lab? Perhaps you’re just convinced money is some sort of mythical object that you might one [more…]

DNA Methylation and Glucocorticoid Resistance Offers Clues to Improve Cancer Drugs

May 12, 2015 Bailey Kirkpatrick

Scientists from St. Jude Children’s Research Hospital conducted a study that illuminates a mechanism by which leukemia cells resist steroids, a key factor detrimental to the success of chemotherapy. This discovery could help create more effective cancer drugs and improve the treatment of many autoimmune related diseases. The researchers looked at a certain type of steroid hormones involved in the immune system, known as glucocorticoids. These hormones are crucial components to the chemotherapy drug cocktail that has helped increase long-term [more…]

How Eating Zinc Could Affect DNA Methylation and the Immune System

April 28, 2015 Bailey Kirkpatrick

Zinc is a mineral that’s vital to our health and is involved in several aspects of cellular metabolism. According to the National Institutes of Health, zinc plays a role in a wide range of important processes like healing wounds, synthesizing proteins and DNA, and the division of cells. It’s even required to be able to taste and smell properly. Published in Molecular Nutrition & Food Research, recent evidence conducted at the Oregon State University also suggests that zinc affects the [more…]

DNA Methylation Influences Continuous Variation in Ant Worker Size

March 31, 2015 Bailey Kirkpatrick

Scientists have thought that differences in traits that exist along a continuum like skin color, height, intelligence, ability to gain weight, and risk for developing diseases were due to genetic and environmental factors. The connection between these two factors and how they interact together, however, has long been uncertain. Researchers from McGill University have conducted an epigenetic study on carpenter ants that reinforces the importance of a key epigenetic mechanism, known as DNA methylation, and supports the hypothesis that environmental [more…]

The Epigenetics of Sleep: 3 Reasons to Catch More Zzz’s

March 3, 2015 Bailey Kirkpatrick

Although the mysteries surrounding sleep are still being uncovered by scientists, we do know that sleep is crucial to our daytime functioning and is vital for processes such as learning and consolidation of memories. Unfortunately, we often fail to get enough sleep even when we know how important it is. Trying to compensate for poor sleep by sleeping more on the weekends or drinking stimulants like coffee just to stay awake can actually end up doing more harm than good. [more…]

Epigenetic Study Finds New Potential Drug Targets for Asthma and Allergies

February 24, 2015 Bailey Kirkpatrick

A new epigenetic study has identified 30 genes connected to allergies and asthma that make people more susceptible to these conditions. Using the newly discovered gene targets from this study, scientists could potentially create drugs to combat allergic diseases and reduce allergic responses. About 6.8 million children and 18.7 million adults in the U.S. suffer from asthma. According to the Asthma and Allergy Foundation of America, 60 million people suffer from both asthma and allergies, affecting 1 out of every [more…]

DNA Methylation Could Explain How People Respond to Fear and Anger

February 17, 2015 Bailey Kirkpatrick

A region of the brain known as the amygdala is normally activated when people perceive fear and anger in others. This region, which is part of the limbic system, conveys the message to other regions of the brain to prepare oneself for what may be a threatening situation. We’ve seen previous research that offers an epigenetic connection between DNA methylation of the serotonin transporter gene (SLC6A4) and how an individual responds to stress. In the present study, peoples’ brains respond [more…]

Epigenetic Changes Result from Breathing in Diesel Exhaust

January 20, 2015 Bailey Kirkpatrick

New research exposes the epigenetic changes and harmful consequences that can occur as a result of exposure to diesel exhaust fumes. Researchers at the University of British Columbia and Vancouver Coastal Health have found that breathing in diesel exhaust fumes can lead to changes in DNA methylation levels, switching on and off certain genes. Diesel exhaust is given off when an engine burns diesel fuel and, according to the Office of Environmental Health Hazard Assessment, “is a complex mixture of [more…]
