Scientits devise dimmer swith to regulate gene expression in mammal cells

Three Boston University biomedical engineers have created a genetic dimmer switch that can be used to turn on, shut off, or partially activate a gene's function. Professor James Collins, Professor Charles Cantor and doctoral candidate Tara Deans invented the switch, which can be tuned to produce large or small quantities of protein, or none at all.

New findings on gene-transcription machinery

For some time, scientists have been tracking down the sequence of biochemical steps required to attract and assemble at the head end of a gene the molecular machinery needed to transcribe that gene to put to work the information it encodes.
