Along with other stresses, heat stress can trigger the expression of certain genes that were not expressed under "normal" conditions [ 4- 6].
Thus, Pax6 acts upstream of MafB, which in turn may trigger the expression of insulin and regulate the PDX-1 and MafA expression required for β-cell maturation.
By disrupting the ability of LasR to trigger the expression of downstream genes and cause a QS response, QslA controls the overall QS activation threshold (Seet and Zhang, 2011).
Such a design allows the disperser cell to trigger the expression of the gene bdcAB50Q in the initial colonizer cell by producing AHL (3OC12HSL), leading to the dispersion and replacement of the biofilm formed by the initial colonizer cells.
The disperser cell (bottom) produces AHL (3OC12HSL) to trigger the expression of the gene bdcAB50Q in the initial colonizer cell (top), leading to the dispersion of the biofilm formed by the initial colonizer cells.
Due to its low boiling point (21°C), acetaldehyde volatized and was broadcast to neighboring cells (receiver) via air to trigger the expression of genes controlled by the cognate acetaldehyde-inducible promoters.
Environmental factors that we are exposed to influence the activation of some DNA and also the regulation of the protein that can read or trigger the expression of said DNA.
And finally, what developmental or environmental factors could trigger the expression of these genes?
Our data suggest that P. aeruginosa may exploit the host-originated signals to trigger the expression of T3SS genes.
From these results we can conclude that lymphocytes trigger the expression of differentiation markers of KΔ75 osteoclast precursors.
It will be important to define what mechanisms underlie this regional identity and trigger the expression of region-specific genes.
