In this model, asymmetric excitation stabilizes the temporal relationship between sequentially activated assemblies, while feedback inhibition between place cells normalizes firing rates (cf. Tsodyks et al., 1996).
Tenascin-C, another ECM glycoprotein that activates assembly of fascin-1 protrusions, suppresses Rho activity in fibroblasts by a syndecan-4 dependent pathway [ 27- 30].
Regulation of this process by Rho/Rab-GTP binding partners on the vesicle and plasma membranes may trigger conformational changes to activate assembly of the subunits [4].
Once activated, the assembly of the T6SS machinery occurs, where the translocation channel is formed by Hcp, VCA0109 and VgrG.
Since caspase-8 is generally activated following assembly of death-inducing signaling complex (DISC) during receptor-mediated apoptosis, we next investigated the expression of Fas ligand, a major inducer of the extrinsic pathway.
Therefore, we concluded that P27 silencing in the MLN4924-treated cells activated the assembly of MAC components via ROS overproduction and further suppressed the major inhibitors by interfering with their protein levels, blocking their phosphorylation or directly sequestering them, thus strengthening the apoptotic signals in the gastric cancer cells.
This was proposed to 'kickstart' initiation of pseudopilus assembly, possibly by activating the assembly ATPase in the cytoplasm (although this remains purely speculative).
During theta states, sequences are generated by independently precessing neurons, whereas during SWRs sequences may result from interactions between consecutively activated cell assemblies.
Anti-mitotic drugs work by perturbing spindle assembly, activating the spindle assembly checkpoint, causing mitotic arrest and triggering apoptosis.
