Traversing the RNA world [RNA] (Journal of Biological Chemistry)

An invitation to write a `Reflections` type of article creates a certain ambivalence: it is a great honor, but it also infers the end of your professional career. Before you vanish for good, your colleagues look forward to an interesting but entertaining account of the ups-and-downs of your past research and your views on science in general, peppered with indiscrete anecdotes about your former competitors and collaborators. What follows will disappoint those who await complaint and criticism, for example, about the difficulties of doing research in the 1960s and 1970s in Eastern Europe, or those seeking very personal revelations. My scientific life has in fact seen many happy coincidences, much good fortune, and several lucky escapes from situations that at the time were quite scary. I have also been fortunate with regard to competitors and collaborators, particularly because, whenever possible, I tried to `neutralize` my rivals by collaborating with them -- to the benefit of all. I recommend this strategy to young researchers to dispel the nightmares that can occur when competing against powerful contenders. I have been blessed with the selection of my research topic: RNA biology. Over the last five decades, new and unexpected RNA-related phenomena emerged almost yearly. I experienced them very personally while studying transcription, translation, RNA splicing, ribosome biogenesis, and more recently, different classes of regulatory non-coding RNAs, including microRNAs. Some selected research and para-research stories, also covering many wonderful people I had a privilege to work with, are summarized below.
