As the majority of PSD-95:GFP puncta were typically juxtaposed against functional presynaptic boutons (Figure S1; see also [35]), the observed increases in PSD-95:GFP puncta number reflected, in all likelihood, increased numbers of glutamatergic synapses.
Positive_regulation (increases) of PSD-95 in synapses
1) Confidence 0.60 Published 2009 Journal PLoS Biology Section Body Doc Link PMC2693930 Disease Relevance 0 Pain Relevance 0.04
An interesting finding was the observation that high levels of network activity were associated with gradual increases in PSD-95:GFP puncta numbers, whereas suppressed activity levels were associated with gradual decreases in PSD-95:GFP puncta numbers (see also [82],[83]).
Positive_regulation (increases) of PSD-95

3) Confidence 0.50 Published 2001 Journal Neuroreport Section Abstract Doc Link 11711866 Disease Relevance 0.70 Pain Relevance 0.62
CONCLUSION: The results indicate not only a significant decrease in MAC for isoflurane but also an attenuation in the NMDA-induced increase in isoflurane MAC in the PSD-95/SAP90 antisense-treated animals, which suggests that PSD-95/SAP90 may mediate the role of the NMDA receptor in determining the MAC of inhalational anesthetics.


Positive_regulation (increase) of PSD-95

To determine whether the observed changes in PSD-95:GFP puncta number and fluorescence intensity were dependent on changes in network activity, we repeated the experiments described above except that here, spontaneous network activity was blocked by adding tetrodotoxin (TTX) about an hour after the experiments were started.
Positive_regulation (changes) of PSD-95 associated with tetrodotoxin
5) Confidence 0.43 Published 2009 Journal PLoS Biology Section Body Doc Link PMC2693930 Disease Relevance 0.06 Pain Relevance 0.18
In practically all experiments, we observed a gradual increase in the total number of PSD-95:GFP puncta, mainly (but not exclusively) due to increased density of PSD-95:GFP puncta along existing dendritic segments, at both spine tips and shafts (Figures 1C and 3B).
Positive_regulation (increase) of PSD-95 in shafts
6) Confidence 0.40 Published 2009 Journal PLoS Biology Section Body Doc Link PMC2693930 Disease Relevance 0 Pain Relevance 0.10
Our findings that suppression of activity broadens the distribution of PSD-95:GFP puncta fluorescence intensities and increases mean PSD-95:GFP fluorescence (Figures 3 and 5) are in general agreement with the aforementioned studies (see also [77],[82]).
Positive_regulation (increases) of PSD-95

When compared with a baseline reflex activity with a single action potential evoked by the TS before the administration of test agents, MO instillation into the descending colon sensitized the evoked activity characterized by elongated firing in the reflex activity in association with increased protein levels of Cdk5, PSD95, and phosphorylated NR2B (pNR2B) but not of total NR2B (tNR2B) in the spinal cord tissue.
