Researchers from Bristol-Myers Squibb Company publish findings in life sciences.

According to recent research from the United States, "We have come a long way in paying RNA its due respect. Originally thought to be nothing more than a shuttle of information from DNA to protein, a bearer of amino acids to the ribosome, and a splicer of messenger RNA, we now know that other RNA species are pivotal in controlling cellular functions that assure normal development and differentiation of immune cells, modulation of inflammatory mechanisms, control of proliferation of a number of hematologic lineages, and spermatogenesis (clearly, vital for the maintenance of the species!)."

"In the future, ribozymes, antisense RNA and oligonucleotides, decoy RNA, peptide-nucleic acid chimeras, and other RNAs will probably be part of the routine armamentarium in a variety of medical practices. Targeting these to the appropriate cell may allow for highly directed therapies, maximizing efficacy and minimizing toxicity. It is a new world, an RNA world, and we will all benefit from the insights broadly outlined in this article. When I was in college and medical school, RNA was known to come in only a few varieties. There was messenger RNA, ribosomal RNA, transfer RNA, and double-stranded RNA in some viruses. And that was that! My. how times have changed!! The truth, as always, is much more complicated than we had thought. We now know that RNA is involved in splicing of mRNA and in cleaving RNA. And, recent studies have revealed even more: DNA transcription, mRNA stability, and levels of protein synthesis are all, to some degree, controlled by an entirely different set of RNAs, such as small RNAs, which come in at least 3 different ...
