  Gene Regulatory Networks
Gene regulatory networks (GRNs) are the on-off switches and rheostats of a cell operating at the gene level.
This was shown by microarray gene chip analyses in yeast cells, and each gene was found to possess a similar cis-regulatory DNA sequence that mediates binding of a particular transcription factor.
A major gene regulatory network in the bacterium Caulobacter is now beginning to be mapped in a comprehensive manner based on genome-wide expression analyses coupled with genetic methods [M. Laub et al., Science 290, 2144­48 (2000)].

The sequences are being assembled currently and the result is expected to average sequence scaffolds of 20-30,000 bp.
Previously we had identified two sequence fragments that recapitulate the temporal and spatial extent of this pattern: a 4 kb region just 5-prime of and including the transcription start site and a region about 1800 bp that occupies most of the intron between the 6th and 7th exons of this transcription unit.
Expression of this regulatory element is enhanced by fusing it with either of two genomic regions downstream of the coding region.

 Regulatory Sequence that Controls the Expression of Allergic-Related Cytokines
Edward Rubin and Kelly Frazer have identified and functionally characterized the conserved non-coding sequence (CNS)-1 as a potent regulator controlling the expression of three genes associated with numerous allergic and atopic diseases.
Since regulatory sequence variation can contribute to human disorders as much as coding variation, this invention has important therapeutic and diagnostic applications.
The newly discovered sequences can be used to diagnose altered CNS sequences that increase or decrease the expression of IL-4, IL-13, and IL-5.

Although one would normally expect a given regulatory element to perform best when it fully matches its consensus sequence, this is generally far from being the case.
Apart from numerous individual codes (sequence patterns) specific for a given species or gene, there are many different general (universal) sequence codes all interacting with one another.
Examples of overlapping of different codes and their interaction are discussed, as well as the role of degeneracy of the codes and the sequence complexity as a function of code density.
