Example: "The team is focused on altering the activity to improve overall efficiency and productivity."
Alternatives: "modifying the task" or "changing the process."
Taken together, these data indicate that PPARgamma activates the UCP2 gene indirectly by altering the activity or expression of other transcription factors that bind to the UCP2 promoter.
The results of this study suggest that, in addition to its role in activation of steroid receptors, CARM1 functions as a transcriptional modulator by altering the activity of many transcriptional factors, especially with regard to androgen independent PCa and colorectal cancers.
Rather than print a retraction, the newspaper printed a clarification that included Dr. Larson's assertion that students were asked, in e-mail messages, for their opinions on altering the activity period schedule.
This showed that spatial exploration evokes activity in ensembles of dentate granule cells, and that randomly altering the activity of these networks with optogenetic stimulation increases the size of the ensembles, or the number of cells within them.
In a paper published last week in Genome Research, researchers studied one such process, called DNA methylation, in which certain molecules within the gene are chemically modified, altering the activity of that particular gene.
Drugs may act directly on the smooth muscle cells, or they may act indirectly for example, by altering the activity of nerves of the autonomic nervous system that regulate vasoconstriction or vasodilation.
