Activation of G1 and S checkpoints depends on tumor protein 53 activity, but activation of G2/M checkpoint is induced by stress-activated MAPK.
In NLP samples innate immunity and IL17 network were activated, but activation of IL10 network was not evident.
Interestingly, ROCK1 activation was not dependent on PDK1 kinase activity, but activation involved the direct binding of PDK1 to ROCK1 at the plasma membrane.
Not only can Stat3 increase NFkB activity in tumors, but activation of Stat3 in immune cells in the tumor is dependent on NFkB and IL-6 which is downstream from NFkB.
AMPK in DBTRG-05MG cells was activated by A769662, but activation and Thr phosphorylation were greatly enhanced when the selective Akt inhibitor MK2206 was added before A769662.
Thus, the left middle frontal gyrus was activated in both conditions, but activation in the right superior frontal gyrus was observed only during presentation of primed pictures.
Pseudowords activated largely similar regions as words, but activation – specifically in the left frontal cortex – was much higher and more extended.
In macrophages stimulation with TGFβ predominantly activates the regulatory SMAD2 and −3 but activation of SMAD1 and −5 was also observed [ 5].
In vitro Oct4 has been shown to function as both an activator and repressor of gene transcription, but activation of Oct4 targets is sufficient to block differentiation and induce reprogramming [ 6].
The nature of NO- and COX-independent endothelial hyperpolarization (EDH) is not fully understood but activation of small- and intermittent-conductance Ca2+-activated K+ channels (SKCa and IKCa) is important.
The pro-apoptotic protein, caspase-3, is activated during growth factor withdrawal in mock-infected HUVECs, but activation is reduced in CMV-infected HUVECs.
