A library of reporters of the global regulators of gene expression in Escherichia coli
Autor: Suchintak Dash, Rahul Jagadeesan, Ines S. C. Baptista, Vatsala Chauhan, Vinodh Kandavalli, Samuel M. D. Oliveira, Andre S. Ribeiro
Publikováno v: mSystems, Vol 9, Iss 6 (2024)
ABSTRACT The topology of the transcription factor network (TFN) of Escherichia coli is far from uniform, with 22 global regulator (GR) proteins controlling one-third of all genes. So far, their production rates cannot be tracked by comparable fluores

Abstract Aims Left ventricular ejection fraction (LVEF) ≤ 40% is a well‐established risk factor for mortality after acute coronary syndromes (ACS). However, the long‐term prognostic impact of mildly reduced ejection fraction (EF) (LVEF 41–49%

Analytical kinetic model of native tandem promoters in E. coli.
Autor: Vatsala Chauhan, Mohamed N M Bahrudeen, Cristina S D Palma, Ines S C Baptista, Bilena L B Almeida, Suchintak Dash, Vinodh Kandavalli, Andre S Ribeiro
Publikováno v: PLoS Computational Biology, Vol 18, Iss 1, p e1009824 (2022)
Closely spaced promoters in tandem formation are abundant in bacteria. We investigated the evolutionary conservation, biological functions, and the RNA and single-cell protein expression of genes regulated by tandem promoters in E. coli. We also stud

Alteration of DNA supercoiling serves as a trigger of short-term cold shock repressed genes ofE. coli
Autor: Suchintak Dash, Cristina S D Palma, Ines S C Baptista, Bilena L B Almeida, Mohamed N M Bahrudeen, Vatsala Chauhan, Rahul Jagadeesan, Andre S Ribeiro
Publikováno v: Nucleic Acids Research. 50:8512-8528
Cold shock adaptability is a key survival skill of gut bacteria of warm-blooded animals. Escherichia coli cold shock responses are controlled by a complex multi-gene, timely-ordered transcriptional program. We investigated its underlying mechanisms.

Added value of autoregulation and multi-step kinetics of transcription initiation
Autor: Mahendra Kumar Prajapat, Andre S. Ribeiro
Publikováno v: Royal Society Open Science, Vol 5, Iss 11 (2018)
Bacterial gene expression regulation occurs mostly during transcription, which has two main rate-limiting steps: the close complex formation, when the RNA polymerase binds to an active promoter, and the subsequent open complex formation, after which

Temperature-Dependent Model of Multi-step Transcription Initiation in Escherichia coli Based on Live Single-Cell Measurements.
Autor: Samuel M D Oliveira, Antti Häkkinen, Jason Lloyd-Price, Huy Tran, Vinodh Kandavalli, Andre S Ribeiro
Publikováno v: PLoS Computational Biology, Vol 12, Iss 10, p e1005174 (2016)
Transcription kinetics is limited by its initiation steps, which differ between promoters and with intra- and extracellular conditions. Regulation of these steps allows tuning both the rate and stochasticity of RNA production. We used time-lapse, sin

Positive supercoiling buildup is a trigger of E. coli’s short-term response to cold shock
Autor: Suchintak Dash, Cristina S.D. Palma, Ines S.C. Baptista, Mohamed N.M. Bahrudeen, Bilena L.B. Almeida, Vatsala Chauhan, Rahul Jagadeesan, Andre S. Ribeiro
Adaptation to cold shock (CS) is a key survival skill of gut bacteria of warm-blooded animals. In E. coli, this skill emerges from a complex transcriptional program of multiple, timely-ordered shifts in gene expression. We identified short-term, cold

Sequence-dependent model of genes with dual σ factor preference
Autor: Ines S. C. Baptista, Vinodh Kandavalli, Vatsala Chauhan, Mohammed N. M. Bahrudeen, Bilena L. B. Almeida, Cristina Palma, Suchintak Dash, Andre S. Ribeiro
Publikováno v: Biochimica et biophysica acta. Gene regulatory mechanisms. 1865(3)
Escherichia coli uses the ability of {sigma} factors to recognize specific DNA sequences in order to quickly control large gene cohorts. While most genes respond to only one {sigma} factor, approximately 5% have dual {sigma} factor preference. The on
