RNA

Researchers frequently turn to C. elegans to learn about not only their biology, but our own. C. elegans is one of the most intimately understood species in biology—the first animal to have its complete genome sequenced or its neural circuitry completely mapped. How did this simple worm become so well studied and a fixture in laboratories around the world?

Researchers in the lab of Whitehead Institute Member David Bartel have identified new genetic sequences that can lead to the degradation of cellular regulators called microRNAs. The finding will allow scientists to learn more about the microRNA degradation pathway, which is critical for some species to survive.

Whitehead Institute Member David Bartel’s lab has uncovered how a key shift in RNA regulation happens early in embryonic development, providing new insight into when and how genes are regulated differently during development.

Whitehead Institute researchers Silvi Rouskin, Ankur Jain, and David Bartel discuss how their RNA research connects to health and disease, including viral infections and neurodegeneration. This podcast is part of a multimedia series on RNA.
