Caltech researchers help unlock the secrets of gene regulatory networks
Date:2/3/2009

nberg says, represents a "codification of everything we know about T cell development. We've found that getting the right balances of the various regulatory signals is absolutely crucial for the T cells to come out right. It gives one a sense of how subtle and sophisticated the regulation can be."

Another study in the special feature by Marianne Bronner-Fraser, the second Albert Billings Ruddock Professor of Biology, focuses on the gene regulatory network underlying neural crest formation in the lamprey, the most primitive living vertebrate. The neural crest is a group of embryonic cells that are pinched off during the formation of the neural tube--the precursor to the spinal cord--and then migrate throughout the developing body to form other nervous system structures.

The study "reveals order and linkages within the network at early stages," Bronner-Fraser says. "Because the neural crest cell type represents a vertebrate innovation, our work in lampreys shows that this network is ancient and tightly conserved to the base of vertebrates," she says.

The fourth of the Caltech papers, by Paul W. Sternberg, the Thomas Hunt Morgan Professor of Biology at Caltech and an investigator with the Howard Hughes Medical Institute (HHMI), and his colleagues, looks at a postembryonic gene regulatory network in Caenorhabditis elegans, a soil-dwelling worm commonly studied by developmental biologists. The gene regulatory network studied by Sternberg and his colleagues controls the formation of the worm's vulva, which connects the uterus with the outside and allows the passage of sperm and eggs.
