However, it remains to be investigated whether occasional stress in shaking-flask cultures such as shifting pH or limited dissolved oxygen is a trigger for SigB activity.
In turn, these toxins may act as a trigger for seizure activity.
As expected, water uptake by the EVOH coating acts as a triggering mechanism for activity.
Obesity is related to the generation of low-grade, chronic inflammation (Lumeng and Saltiel, 2011), and gut-derived antigens are considered potential triggers for this activity.
The point is not that these chemical triggers for sexual activity will follow the same course in men and women, but rather, that the study shows one possible way, in a relatively advanced animal, for how differences can arise.
Given that the apomictic A.monanthes clade and related lineages show strong patterns of reticulate evolution, it is possible that these processes may be acting as triggers for retrotransposon activity leading to the range of 1C x-values observed.
P-Rex is substantially activated by the lipid second messenger PtdIns 3,4,5 P3, which is generated by the activity of phosphoinositide 3-kinase (PI3K), suggesting that PtdIns 3,4,5 P3 may be an upstream trigger for enhancing Rac activity.
The illumination design feature incorporated in these devices allows for direct placement of the UV source in immediate proximity with the neuron of interest and provides a means for optical triggering of activity in the neuronal culture.
These soluble factors may be the trigger for increased osteoblastic activity and resulting osteolysis [ 13, 14].
Recent studies have suggested that the trigger for IRE1 endoribonuclease activity is not phosphorylation but a conformational change in the kinase domain induced by cofactor (ATP or ADP) binding.
