The Many Lives of mRNA - Stirling Churchman, PhD

In this presentation, Dr. Stirling Churchman of Harvard Medical School describes the dynamic life cycle of RNA. She reveals how RNA molecules move through the cell, how long they linger in each compartment, and what this tells us about gene regulation and cellular health.
Using metabolic labeling, biochemical fractionation, and computational modeling, Dr. Churchman’s team uncovers surprising insights into RNA kinetics, including the discovery of widespread nuclear degradation in specific gene sets. Learn how RNA flow rates vary across the genome, how machine learning helps identify key regulatory features, and why understanding RNA dynamics is crucial for decoding gene expression and disease mechanisms.
