The transcriptional network of Escherichia coli is currently the best-understood regulatory
network of a single cell. Motivated by statistical evidence, suggesting a hierarchical modular …

Background Glucose is the preferred carbon and energy source for Escherichia coli. A
complex regulatory network coordinates gene expression, transport and enzyme activities in …

Background Previous studies have used different methods in an effort to extract the modular
organization of transcriptional regulatory networks. However, these approaches are not …

MicroRNAs play important roles in cancer biology. Calcitriol, the hormonal form of vitamin D
3 , regulates microRNAs expression in tumor cells. In the present study we asked if calcitriol …

Some organism-specific databases about regulation in bacteria have become larger, accelerated
by high-throughput methodologies, while others are no longer updated or accessible. …

Gene regulatory networks are graph models representing cellular transcription events. Networks
are far from complete due to time and resource consumption for experimental validation …

Background The regulation of gene expression at the transcriptional level is a fundamental
process in prokaryotes. Among the different kind of mechanisms modulating gene …

The availability of databases electronically encoding curated regulatory networks and of
high-throughput technologies and methods to discover regulatory interactions provides an …

Corynebacterium glutamicum is a Gram-positive, anaerobic, rod-shaped soil bacterium able
to grow on a diversity of carbon sources like sugars and organic acids. It is a …

A comparative proteomic study at 6 h of growth in minimal medium (MM) and bacteroids at
18 days of symbiosis of Rhizobium etli CFN42 with the Phaseolus vulgaris leguminous plant …
