Moreover, the long-lived Ghrhrlit/lit mice displayed elevated levels of several bile acids and exhibited increased FXR-dependent transcription of numerous xenobiotic detoxification genes; if administered to food consumed by wild-type mice, cholic acid - one of these bile acids - mimicked the FXR-governed gene expression pattern observed in Ghrhrlit/lit mice [ 81, 82].
Regulation of gene expression of this unicellular eukaryote is probably governed, as for all eukaryotes, by common mechanisms including epigenetic, transcriptional as well as post-transcriptional regulation.
The efficiency with which small interfering RNAs (siRNAs) down-regulate specific gene expression in living cells is variable and a number of sequence-governed, biochemical parameters of the siRNA duplex have been proposed for the design of an efficient siRNA.
This suppresses gene expression.
His money is on some form of gene marking (known as epigenetics) that controls gene expression and function during development.
In the lingo, evolution is regulatory (involving patterns of gene expression), not structural (involving the precise proteins coded by genes).
But new instruments known as gene expression chips allow researchers to track which of a cell's genes are active.
When all of the pieces, or genes, are identified, the team can assemble a gene expression map of the brain.
— didn't really correlate with gene expression at all," Cole said.
"The whole gene expression field," he said, "is going to start over from scratch".
Why, researchers ask, would growing embryos in petri dishes elicit changes in gene expression?
