A team of researchers with the University of California has found a way to show how historical contingencies constrained the evolution of a gene regulatory network. In their paper published in the journal Nature, the team ...
A team led by Rice University bioengineering researchers has decoded the mechanism that some bacteria use to make life-or-death decisions during extremely tough times.

(Phys.org)—Gene expression plays a central role in the orchestration of virtually all cellular processes. While inducible promoters have proven invaluable in understanding regulatory networks by modifying gene expression ...
Environment is not the only factor in shaping regulatory patterns—and it might not even be the primary factor, according to a new Rice University study that looks at how cells' protein networks relate to a bacteria's genome.

(Phys.org)—As an animal develops from an embryo, its cells take diverse paths, eventually forming different body parts—muscles, bones, heart. In order for each cell to know what to do during development, it follows a ...
