Sparse regulatory networks

, 2010
In many organisms the expression levels of each gene are controlled by the activation levels of known "Transcription Factors" (TF). A problem of considerable interest is that of estimating the "Transcription Regulation Networks" (TRN) relating the TFs ...

Cooperative mechanisms of LexA and HtpG in the regulation of virulence gene expression in Pseudomonas plecoglossicida

Current Research in Microbial Sciences
LexA is a well-known transcriptional repressor of DNA repair genes induced by DNA damage in Escherichia coli and other bacterial species. Recently, this paradigm—that LexA solely regulates the SOS response—has been challenged as studies reveal its ...

Homodimerization and heterodimerization requirements of Acinetobacter baumannii SOS response coregulators UmuDAb and DdrR revealed by two-hybrid analyses [PDF]

, 2020
The multidrug-resistant pathogen Acinetobacter baumannii displays unusual control of its SOS mutagenesis genes, as it does not encode a LexA repressor, but instead employs the UmuDAb repressor and a small protein, DdrR, that is uniquely found in ...

Consensus and meta-analysis regulatory networks for combining multiple microarray gene expression datasets [PDF]

, 2008
Microarray data is a key source of experimental data for modelling gene regulatory interactions from expression levels. With the rapid increase of publicly available microarray data comes the opportunity to produce regulatory network models based on ...
