In recent years, bacterial small regulatory RNAs (sRNAs) have been demonstrated to be powerful modulators of gene expression. Whether it is by modulating mRNA functions or protein activities, sRNAs often employ unexpected and extremely diverse mechanisms to modify the genetic output. Although the first sRNAs were characterized as molecules blocking(More)
Bacteria express large numbers of non-coding, regulatory RNAs known as 'small RNAs' (sRNAs). sRNAs typically regulate expression of multiple target messenger RNAs (mRNAs) through base-pairing interactions. sRNA:mRNA base-pairing often results in altered mRNA stability and/or altered translation initiation. Computational identification of sRNA targets is(More)
The RNA chaperone Hfq is a key regulator of the function of small RNAs (sRNAs). Hfq has been shown to facilitate sRNAs binding to target mRNAs and to directly regulate translation through the action of sRNAs. Here, we present evidence that Hfq acts as the repressor of cirA mRNA translation in the absence of sRNA. Hfq binding to cirA prevents translation(More)
There are many reasons an organization may choose to implement electronic health records. The challenge is to acknowledge the benefits and deficiencies of the electronic health record, to understand the driving forces for implementation and the barriers to it, and to effect change in the workplace and consumer behaviour. Indeed, one challenge is the(More)
Riboswitches are mRNA regulatory elements that control gene expression by altering their structure in response to specific metabolite binding. In bacteria, riboswitches consist of an aptamer that performs ligand recognition and an expression platform that regulates either transcription termination or translation initiation. Here, we describe a dual-acting(More)
