About Andrea P
Andrea received her B.S. in Biology with minors in Chemistry and Neuroscience from Duke University. She first fell in love with biology when she learned about the magnificent powers of protein folding, and then naturally wanted to know who was in charge. She’s fascinated by the finer controls of epigenetic modifications. In her downtime, she enjoys hiking with her dog and going for long drives to explore new places.

Epigenetic Changes May Pass Avoidance Behavior Down Multiple Generations

September 10, 2019 Andrea P

Science classes teach that an individual’s traits are mainly encoded in their genetic sequence—or DNA—which then gets transcribed into RNA that subsequently gets translated into the proteins that carry out cellular functions. But while this is generally true for the majority of traits, it does not account for how all characteristics are passed down across generations. It turns out, epigenetics may play a large role in how traits are inherited. Researchers at Princeton’s Department of Molecular Biology and the Lewis-Sigler [more…]

Nervous System’s Glial Cells May Epigenetically Respond to Stress

August 20, 2019 Andrea P

According to a recent survey by the American Psychological Association, three out of every four Americans reports experiencing a symptom of stress in the past thirty days. We are constantly faced with all kinds of stressors—personal, financial, career, news, and so on—with increasing frequency particularly as the role of mobile communications continues to grow in daily prevalence. A scientific understanding of how this is detrimental in the long run has been growing, with studies revealing that exposure to stressors ranging from violence [more…]

Cancer Genes May Have Been Epigenetically Silenced Over Time

August 6, 2019 Andrea P

The factors contributing to the development of cancer in an individual are often complex and varied. Sometimes they are more straightforward, like when someone carries a specific gene known to indicate cancer risk; for example, specific mutations of BRCA1 or BRCA2 are linked to breast cancer. But usually, these risk factors are not so directly observable, making cancer risk detection—and possibly even cancer prevention—difficult. Any insights into what leads into the development of cancer are therefore critical. It’s not just [more…]

Daytime Sleepiness May Be Result of Epigenetic Change

July 23, 2019 Andrea P

Sleep is one of the most important factors in maintaining a healthy lifestyle. For most of us, it’s our favorite activity, yet we somehow never get enough of it. Sleep deprivation can lead to weight gain, memory problems, and increased fatigue throughout the day. It turns out that feeling sleepy during the day may be a separate issue, and could be attributed to a change in a person’s epigenetics. Daytime fatigue creeping up so persistently that people can’t stay awake [more…]
