After several years of waning enthusiasm for an approach to drug-making that was once called revolutionary, interest in RNA medicines is suddenly on the upswing, and Boston area start-ups are at the front of the resurgence.
The field got a high-octane boost last week when Watertown startup Dicerna Therapeutics Inc. — a company developing drugs using a gene-silencing technology called RNA interference — became the first Massachusetts biotech to go public this year.
