Unraveling Chronological Age: Epigenetic Modifications as Indicators of Cognitive Decline

Author: Tiffany Ang, Class of 2025 Figure 1: A visualization of epigenetic modifications that shape gene expression without changing the genetic code. DNA methylation-derived epigenetic clocks are powerful tools for assessing biological aging and age acceleration–the difference between biological and chronological age. Unlike chronological age, which fails to capture the impact of biological and environmental influences, age acceleration explains individual differences in cognitive functions such … Continue reading Unraveling Chronological Age: Epigenetic Modifications as Indicators of Cognitive Decline

Epigenetic Age Acceleration More Accurately Predicts Memory Decline Than Chronological Age

Author: Vignesh Subramanian, Class of 2024 Figure 1: Increasing evidence suggests biological aging, measured by examining the extent of methylation of cells’ DNA, is a stronger predictor of diminishing cognitive abilities than chronological age.  Title: Epigenetic Age Acceleration More Accurately Predicts Memory Decline Than Chronological Age Age acceleration is the term used to describe the difference between an individual’s chronological age, the length of time … Continue reading Epigenetic Age Acceleration More Accurately Predicts Memory Decline Than Chronological Age

EN1 Protein Has Been Recognized as Playing a Key Role in Pancreatic Cancer

Author: Sean Krivitsky ‘26 Pancreatic cancer stands out as one of the most severe forms of cancer, accounting for the third most cancer-related deaths. Pancreatic ductal adenocarcinoma (PDA) is a form of pancreatic cancer that involves a high degree of metastasis, which refers to the ability of the cancer to spread. This cancer develops as a result of mutations that result in the activation of … Continue reading EN1 Protein Has Been Recognized as Playing a Key Role in Pancreatic Cancer

The Influence of Epigenetic Age on Cognitive Decline

 Julia Chivu ’23 As people age, their cognitive abilities tend to decline. While chronological age is commonly cited as a reason for this decline, it often fails to explain why some individuals have higher cognitive performance than others of the same age. To address this, epigenetic clocks, which analyze DNA methylation at specific genomic sites correlated with aging, are emerging as useful tools for predicting … Continue reading The Influence of Epigenetic Age on Cognitive Decline
