The Inducible lac Operator-Repressor System Is Functional in Zebrafish Cells
BackgroundZebrafish are a foundational model organism for studying the spatio-temporal activity of genes and their regulatory sequences. A variety of approaches are currently available for editing genes and modifying gene expression in zebrafish ...

Supercoiling Effects on Short-Range DNA Looping in E. coli. [PDF]
DNA-protein loops can be essential for gene regulation. The Escherichia coli lactose (lac) operon is controlled by DNA-protein loops that have been studied for decades.

Switching off: the phenotypic transition to the uninduced state of the lactose uptake pathway [PDF]
The lactose uptake-pathway of E. coli is a paradigmatic example of multistability in gene-regulatory circuits. In the induced state of the lac-pathway, the genes comprising the lac-operon are transcribed, leading to the production of proteins which import and metabolize lactose.

Growth rate regulation of lac operon expression in Escherichia coli is cyclic AMP dependent [PDF]
In contrast to the ribosomal RNA gene expression increasing with growth rate, transcription of the lac operon is downregulated by cell growth rate. In continuous culture, growth rate regulation of lac promoter was independent of carbon substrate used and

Development of a Positive-readout Mouse Model of siRNA Pharmacodynamics
Development of RNAi-based therapeutics has the potential to revolutionize treatment options for a range of human diseases. However, as with gene therapy, a major barrier to progress is the lack of methods to achieve and measure efficient delivery for ...

CRISPR SWAPnDROP -- A multifunctional system for genome editing and large-scale interspecies gene transfer [PDF]
The need for diverse chromosomal modifications in biotechnology, synthetic biology and basic research requires the development of new technologies. With CRISPR SWAPnDROP, we extend the limits of genome editing to large-scale in-vivo DNA transfer between bacterial species.

Use of a Role-Playing Activity To Increase Student Understanding of Bacterial Gene Regulation
Undergraduate students often struggle to understand the basics of bacterial gene regulation, a key concept in microbiology. They find it hard to visualize the architecture of a bacterial operon or how the gene, RNA, and protein components interact with ...
