Along with other stresses, heat stress can trigger the expression of certain genes that were not expressed under "normal" conditions [ 4- 6].
Gene mutations that truncate the encoded protein can trigger the expression of related genes.
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.
A similar effect was observed with the mitochondria-selective superoxide scavenger MitoTEMPO (50 μM)23 (Figure 4i), thus confirming that ROS produced by mitochondria when they are deprived from glycolytic fuels trigger the expression of both the lactate transporter and its chaperone.
This pathway functions like a Rube Goldberg machine to pass a signal sequentially from outside the cell, across the cell's membrane and into the nucleus to trigger the expression of genes important in cellular growth and development.
The activated signalling pathways trigger the expression of genes associated with the interdependency metabolism pathway, including those involved with sugar, phenylpropanoid, flavonoids and lipid metabolisms; these metabolites, most likely EGCG, suppress the invading pathogen.
The secreted type-I IFNs (IFN-α and IFN-β) bind to the IFN receptor (IFNAR) in an autocrine and paracrine manner21,22, and signal through the Janus kinase (JAK signal transducer and activator of transcription protein (STAT) pathway to trigger the expression of hundreds of IFN-stimulated genes (ISGs) with antiviral functions23,24.
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.
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).
