In another such pathway, the vernalization pathway, prolonged cold elevates COOLAIR transcription and silences FLC in a Polycomb-mediated epigenetic process [ 10, 11].
Testing AEE788 in the tumor models revealed that the combination of dovitinib + AEE788 resulted in blockade of the PI3K/Akt/mTOR pathway, prolonged tumor stasis and in the 4T1 model, a significant decrease in lung metastasis.
It can be envisioned that following a first wave of direct mitochondrial permeabilization induced by the HIPK2/Pin1/p53 pathway, prolonged signaling along the same axis reaches the threshold for activating p53 target genes, thus amplifying the response through a full apoptotic program.
Finally, GM-CSF, a survival factor for neutrophils, triggers ERK activation and interference with ERK or other life span prolonging signalling pathways may allow for induction of neutrophil apoptosis.
However, given its role as a master-regulator of several pathways, prolonged NF-κB inhibition can result in severe side effects such as immunodepression and liver damage [ 78, 79].
Our results revealed a dynamic, time-dependent NF-κB pathway response to FHA where, despite the initial rapid activation of the pathway in macrophages, prolonged exposure to FHA inhibited this pathway and suppressed subsequent responses to other inflammatory signals.

Interestingly, neutrophil elastase (NE) released with NETs is also able to enhance platelet adhesion and activation (inactivation of ADAMTS13) and coagulation with inhibition of tissue factor pathway inhibitor (prolonged tissue factor-induced initiation) and thrombomodulin (impaired activation of protein C).
Multiple lines of evidence from animal models suggest that a functional p53 pathway favors prolonged survival.
In the same model system, oscillations have been induced by the addition of growth factors or prolonged activation of MAPK pathway, and stalled by MEK inhibitors [ 40].
