Dr. Afshin Beheshti: MicroRNAs and COVID-19

Dr. Afshin Beheshti begins this episode by explaining what microRNAs are and why they are emerging as an important area of biological research. He then explains how microRNAs relate to viruses, which is a recently developing area of research in this already young field of study. Dr. Beheshti then tells the story of how he started to discover that microRNAs could be a driver of COVID-19 infections. 

His story begins by using microRNA analysis tools to analyze COVID-19 infected patients from China which predicted a handful of microRNAs that could be involved in COVID-19 infection. He discusses how his team decided to focus on microRNA 2392 and how he continued to dig further into how it could be connected to COVID-19. His story then weaves through tales of successful collaborations with a large team of scientists that led to studying RNA samples from deceased COVID-19 patients, testing expressing the microRNA in healthy cells, analyzing multiple organs in COVID-19 infections, and testing a delivery system for a microRNA antagonist as a potential novel therapeutic.

We conclude with a quick discussion of the connection between microRNAs and space biology and space omics research.
