Making Sense of Antisense Oligonucleotides

How does a potential drug discovered in the lab ultimately end up in people? We tackle this question in the context of exciting gene-modifying therapies called antisense oligonucleotides (ASOs). In this episode, we speak with Dr. Tim Miller to break down the science behind ASOs and learn more about his work in finding a cure for a genetic form of amyotrophic lateral sclerosis (ALS).

This episode was written and produced by Nancy Cai, Devika Nair, and Arja Ray.
