We report that two-stage dynamic control improves bioprocess robustness as a result of the dynamic deregulation of central metabolism. Dynamic control is implemented during stationary phase using combinations of CRISPR interference and controlled proteolysis to reduce levels of central...

mmnet: An R Package for Metagenomics Systems Biology Analysis.

BioMed research international

Cao Y, Zheng X, Li F, Bo X.
PMID: 26421278
Biomed Res Int. 2015;2015:167249. doi: 10.1155/2015/167249. Epub 2015 Sep 03.

The human microbiome plays important roles in human health and disease. Previous microbiome studies focused mainly on single pure species function and overlooked the interactions in the complex communities on system-level. A metagenomic approach introduced recently integrates metagenomic data...

Guiding the Refinement of Biochemical Knowledgebases with Ensembles of Metabolic Networks and Machine Learning.

Cell systems

Medlock GL, Papin JA.
PMID: 31926940
Cell Syst. 2020 Jan 22;10(1):109-119.e3. doi: 10.1016/j.cels.2019.11.006. Epub 2020 Jan 08.

Mechanistic models explicitly represent hypothesized biological knowledge. As such, they offer more generalizability than data-driven models. However, identifying model curation efforts that improve performance for mechanistic models is nontrivial. Here, we develop a solution to this problem for genome-scale...

Assessing Escherichia coli metabolism models and simulation approaches in phenotype predictions: Validation against experimental data.
