DNA looping: the consequences and its control [PDF]

open access: yes, 2006
The formation of DNA loops by proteins and protein complexes is ubiquitous to many fundamental cellular processes, including transcription, recombination, and replication.

Physiological regulation of a decontrolled lac operon [PDF]

open access: yesJournal of Bacteriology, 1977
The expression of the lac operon was studied under a variety of growth conditions in induced and in constitutive cells of Escherichia coli that carried different catabolite-insensitive lac promoters. Use of such "decontrolled" lac operons permitted a study of the expression of an operon that was presumably subject only to passive control. Since the use

Concentration and Length Dependence of DNA Looping in Transcriptional Regulation [PDF]

open access: yes, 2008
In many cases, transcriptional regulation involves the binding of transcription factors at sites on the DNA that are not immediately adjacent to the promoter of interest.

Development of a Positive-readout Mouse Model of siRNA Pharmacodynamics

open access: yesMolecular Therapy: Nucleic Acids, 2013
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 ...

GlaR (YugA)—a novel RpiR‐family transcription activator of the Leloir pathway of galactose utilization in Lactococcus lactis IL1403

open access: yesMicrobiologyOpen, 2019
Bacteria can utilize diverse sugars as carbon and energy source, but the regulatory mechanisms directing the choice of the preferred substrate are often poorly understood.

A modified consumer inkjet for spatiotemporal control of gene expression.

open access: yesPLoS ONE, 2009
This paper presents a low-cost inkjet dosing system capable of continuous, two-dimensional spatiotemporal regulation of gene expression via delivery of diffusible regulators to a custom-mounted gel culture of E. coli. A consumer-grade, inkjet printer was

In silico approach for the identification of mirror repeats in selected operon genes of Escherichia coli strain K-12 substrain MG1655

open access: yesBiomedical and Biotechnology Research Journal, 2022
Background: The repeating elements in the genes or genomes of living organisms are associated with a variety of functions at the molecular level. Mirror repeats (MRs) are unique type of repeat sequences among them, which are found to be linked with H-DNA

Regulation of bistability in the std fimbrial operon of Salmonella enterica by DNA adenine methylation and transcription factors HdfR, StdE and StdF [PDF]

open access: yes, 2019
Bistable expression of the Salmonella enterica std operon is controlled by an AND logic gate involving three transcriptional activators: the LysR-type factor HdfR and the StdE and StdF regulators encoded by the std operon itself.

Direct measurements of IPTG enable analysis of the induction behavior of E. coli in high cell density cultures

open access: yesMicrobial Cell Factories, 2012
Background The E. coli lac operon and its components have been studied for decades, and lac-derived systems are widely used for recombinant protein production.
