RNA Shows Its Sensitive Side
The scientific take on the character of RNA has grown increasingly complex in recent years. Once thought of as a handmaiden to DNA, RNA now appears to be a sophisticated regulator of gene expression. One form of the nucleic acid, microRNA, may regulate a host of vital functions in the cell. A study by (left to right) Changchun Xiao, Klaus Rajewsky, Dinis Pedro Calado, and colleagues, shows that in B cells of the mouse immune system, a particular microRNA specifically targets a certain transcription factor, resulting in finely tuned levels of B cells produced by the mice.
