By: A. Westbrook *, X. Tang *, R. Marshall*, C. Maxwell n, J. Chappell *, D. Agrawal *, M. Dunlop *, V. Noireaux * ...

author keywords: Bayesian methods; CRISPRi; model-guided design; RNA-based circuits; sRNA
MeSH headings : CRISPR-Cas Systems; Cell-Free System / chemistry; Cell-Free System / metabolism; Clustered Regularly Interspaced Short Palindromic Repeats; Models, Chemical; RNA / chemistry; RNA / metabolism; Transcription, Genetic; Transcriptional Activation
TL;DR: This work individually characterize two modes of RNA-based transcriptional regulation, using small transcription activating RNAs (STARs) and CRISPR interference (CRISPRi), and shows how their distinct regulatory timescales can be used to engineer a composed feedforward loop that creates a pulse of gene expression.

2017 journal article

Short DNA Containing chi Sites Enhances DNA Stability and Gene Expression in E-coli Cell-Free Transcription-Translation Systems

BIOTECHNOLOGY AND BIOENGINEERING, 114(9), 2137–2141.

By: R. Marshall*, C. Maxwell n, S. Collins n, C. Beisel n & V. Noireaux *

author keywords: Escherichia coli; gene circuits; prototyping; RecBCD; synthetic biology; TXTL
MeSH headings : Cell-Free System / physiology; DNA, Bacterial / genetics; Escherichia coli / genetics; Exodeoxyribonuclease V / genetics; Gene Expression Regulation, Bacterial / genetics; Genetic Engineering / methods; Protein Biosynthesis / genetics; Transcription, Genetic / genetics
TL;DR: It is shown that double-stranded DNA encoding χ sites-eight base-pair sequences preferentially bound by the RecBCD recombination machinery-stabilizes linear DNA and greatly enhances the TXTL-based expression and activity of a fluorescent reporter gene, simple regulatory cascades, and T7 bacteriophage particles.
