It is hypothesized that the crucial step in NLR activation lies in the oligomerization of the NACHT-domain, thereby forming an active signaling platform (e.g. the inflammasome or nodosome [7], [8], respectively), which allows binding of adaptor molecules and effector proteins, ultimately leading to an inflammatory response.
Caspase 3 activation lies at the center of the caspase-mediated apoptosis [ 42].
Upstream to caspase activation lies the apoptosome, the subject of the chapter by Cecconi and Ferraro.
Part of the difficulty in assessing these differences in activation lies in the indirect measures used to measure ATR activation.
However, this regulation, albeit a likely key event in the Shh pathway activation, lies downstream to Ptch1 functions.
The significance of SNS activation lies in its direct actions on the myocardium and vasculature, which can result in hypertension, tachycardia, and, potentially, dysrhythmias.
Interestingly, we observed that PMT-induced Akt activation lies upstream of the mTOR complex at early time-points (3 h, 6 h) since treatment with rapamycin did not abrogate Akt phosphorylation.
This indicates that D2 activation lies upstream of MyoD in the linear cascade of myogenesis in satellite cells, which requires – for its normal sustained expression during regeneration or development – both T3 from the plasma and that generated by D2.
Since spermine NONOate exposure increased AMPK-α1-associated activity in human skeletal muscle (Fig. 1c), as well as phosphorylation of AMPK and ACC in L6 myotubes (Fig. 3c, e), we determined whether AMPK activation lies downstream of cGMP.
These correlate to the opening of the anus and activity in PDF and RN2, however no functional test of the hypothesis that ASN activation lies downstream of PDF, RN2 and anal opening is shown.
