title: Gene regulation by transcription factors and microRNAs.
abstract: The properties of a cell are determined by the genetic information encoded in its genome. Understanding how such information is differentially and dynamically retrieved to define distinct cell types and cellular states is a major challenge facing molecular biology. Gene regulatory factors that control the expression of genomic information come in a variety of flavors, with transcription factors and microRNAs representing the most numerous gene regulatory factors in multicellular genomes. Here, I review common principles of transcription factor- and microRNA-mediated gene regulatory events and discuss conceptual differences in how these factors control gene expression.
