11.   The current commercial techniques for activating therapeutic genes require the continual application of a drug to keep the gene active.

12.   The six newly identified genes, when functioning properly, activate the BRCA genes as needed, the researchers said.

13.   Weintraub gained international recognition for developing technology to demonstrate what activates a gene.

14.   When a cell activates a gene, scientists say the cell expresses it.

15.   That gene is active in a wide variety of cancers.

17.   They found that in fruit flies called Drosophila, the gene is activated in only a tiny fraction of brain cells.

18.   They looked at which genes were activated or deactivated by the TZD.

19.   They speculated that Delta-FosB also activates other genes that produce biochemical compounds called glutamates, which carry messages in brain cells.

20.   Weiss co-wrote a paper published last week about how SRY activates a gene that eliminates female tissue in the developing male embryo.
