Changes in DNA and gene function are the engines that drive evolution. These seemingly small modifications in an organism’s evolutionary journey ultimately dictate its fate —  deciding which traits will be safeguarded and transmitted through generations, and which new traits will emerge. Whitehead Institute researchers are studying how organisms sharing a common ancestor develop unique traits over time, diverging from one another. These traits — encoded in the genes — impact their chances of survival and reproduction.

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.

Whitehead Institute researchers are studying how RNA molecules group together for the good of the cell and our health — and what happens when these groupings go awry.

Researchers at Whitehead Institute have made important discoveries that have uncovered the prevalence, characteristics, and functions of regulatory RNAs. Their work has transformed researchers’ understanding of gene regulation and revealed a complex, elegant system that tailors gene expression for each cell type and tissue.
