Can mRNA disrupt the drug industry?

Used by all living things to make proteins, messenger RNA is one of the least explored frontiers of drug discovery. Moderna Therapeutics, and an increasing number of similarly well-funded biotech firms, is built on the promise that mRNA can be turned into a powerful treatment for genetic diseases, cancer, infectious diseases, and more. But turning mRNA into a drug is far from trivial, and companies have kept their technology largely under wraps. Now, Moderna is offering a glimpse of its massive research engine. Read on to learn how researchers are trying to move mRNA out of the lab and into the clinic.  – Read more.
