[RNAissance: is there a future for RNA therapeutics?]

The central dogma in molecular biology states that genetic information is transmitted from DNA to RNA to proteins, but not the other way round. Thanks to a recent technological revolution - the 'RNAissance' - it has, however, become clear that RNA is not solely a messenger for passing on the genetic information necessary for protein synthesis, but that RNA also plays an important role in sickness and health. In the past 5 years alone more than 100 therapies with (complementary) RNA molecules have been investigated in Phase 1 trials, and a quarter of these have also been investigated in Phase 2 or 3 trials. The dramatic increase in the number of pharmaceutical companies that are developing RNA therapeutics illustrates the enormous potential of these medicines. Once the toxicity and the costs of RNA therapeutics can be limited, these medicines - personalized or not - could soon be prescribed for patients with a wide range of chronic conditions.
