These results indicate that pyocyanin requires the expression of Asm if it is to mediate the mitochondrial release of cytochrome c and to trigger neutrophil death.
Another major role of Cyt c it to trigger programmed cell death when it is released from the mitochondria into the cytosol (see [ 37] for a review).
For example, with a heating slope of 1°C/s, it takes approximately five seconds to pass from the threshold of activation of C polymodal nociceptors to that of the Aδ polymodal nociceptors; this time period is ample to enable activation of C-fibers to trigger a reaction even before Aδ fibers have been activated.
On the other hand, none of the TAL effectors from the limited-host-range strains (pathotypes B and C) was able to trigger the hypersensitive response (HR) observed in grapefruit plants when expressed heterologously in other strain, suggesting that TAL effectors from citrus canker pathogens do not limit host range but rather contribute to virulence associated functions [ 4, 21].
By contrast, Cd was found to trigger the opposite response coupled the up-accumulation of molecular chaperones in shoot of mycorrhizal plants relative to those metal-free.
Therefore, through the phosphorylation and inhibition of FBW7, the KRAS-MAPK axis may mainly rescue c-Myc expression to trigger a major alteration in the transcription profile towards malignancy and cell growth advantage.
Perlucin contains a carbohydrate recognition domain, and because this protein is expressed both in the mantle and in the gills and the digestive tract, it has been suggested that perlucin could play a role in non-self antigen recognition, similarly to other C-type lectins to trigger the immune response [ 48].
Since HGF is enriched in the stroma of both the prostatic gland [ 40] and bone marrow [ 41] and is considered to be sufficient to trigger c-Met activation, acquisition of the c-Met activity in the absence of environmental HGF may facilitate tumor cells to survive and metastasize in a scenario where exogenous HGF is lacking.
As controls, we microinjected either IRDye, cytochrome c, or IRDye and Saccharomyces cerevisiae cytochrome c (yeast cytochrome c), which is structurally similar to mammalian cytochrome c but lacks the ability to trigger caspase activation 14.
Spiking activity is also able to trigger c-Fos expression by increasing Ca levels [13], [14].
Thus, in ovarian cancer cells, atrazine involves ERα and the EGFR/MAPK pathway to trigger c-fos protein increase.
