The major downstream site used by Zfy2 is difficult to define because the major Zfy2 3′ RACE product, at 16 d.p.p., has its 3′ end within a genomic polyadenosine tract (dA14) (Fig. 4A).
Given the tremendous physiological and clinical importance of the Kp/GPR54 signaling system, we explored the contributions of the GPR54-coupled Gq/11 and β-arrestin pathways on the activation of a major downstream signaling molecule, ERK, using Gq/11 and β-arrestin knockout mouse embryonic fibroblasts.
In order to understand the relevance of oncogenic RAS and its dependence on its major downstream effectors, RAF and PI3K, we used a previously described doxycycline (dox -inducible shRNA system [29] to studox -inducible of RAshRNAckdown on cellular proliferation and tumor growth.
Since Akt is one of the major downstream targets of PI3K signaling, its phosphorylation status is commonly used to monitor the activity of the PI3K/Akt pathway.
In cell lines with acquired resistance, the use of cetuximab does not induce alterations of the major downstream transducers of EGFR.
Shell first asked its major downstream operating companies to evaluate current strategies against two A-type scenarios, using the B2 scenario as a sensitivity check.
Using genome-wide microarray analysis, we found that FOXO factors are the major downstream transcriptional effectors of PI3K/AKT signalling.
Thus, major downstream signaling was not blocked by inhibiting EGFR activation which is in line with previous clinical studies using EGFR inhibitors [ 24, 33, 41] and might in part explain the resistance to anti-EGFR therapy.
ADP-ribosyltransferases (ARTD1 16) have emerged as major downstream effectors of NAD+ signaling in the cell.
Aramco began this process in the 1990s, building off of its domestic downstream and its Motiva investment, by participating in major downstream operations across Asia.
