Epigenetic mechanisms have been proposed to play crucial roles in mammalian development, but their precise functions are only partially understood. To investigate epigenetic regulation of embryonic development, we differentiated human embryonic stem cells into mesendoderm, neural progenitor cells, trophoblast-like cells, and mesenchymal stem cells and(More)
RNA can adopt different conformations in response to changes in the metabolic status of cells, which can regulate processes such as transcription, translation, and RNA cleavage. We previously proposed that an RNA conformational switch in an untranslated satellite RNA (satC) of Turnip crinkle virus (TCV) regulates initiation of minus-strand synthesis (G.(More)
Efficient replication of plus-strand RNA viruses requires a 3' proximal core promoter and an increasingly diverse inventory of supporting elements such as enhancers, repressors, and 5' terminal sequences. While core promoters have been well characterized, much less is known about structure-functional relationships of these supporting elements. Members of(More)
