1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The N-methyl-D-aspartate receptor (NMDA-R) and brain spectrin, a protein that links membrane proteins to the actin cytoskeleton, are major components of post-synaptic densities (PSDs). Since the activity of the NMDA-R channel is dependent on the integrity of actin and leads to calpain-mediated spectrin breakdown, we have investigated whether the actin-binding spectrin may interact directly with NMDA-Rs. Spectrin is reported here to interact selectively in vitro with the C-terminal cytoplasmic domains of the NR1a, NR2A and NR2B subunits of the NMDA-R but not with that of the AMPA receptor GluR1. Spectrin binds at NR2B sites distinct from those of alpha-actinin-2 and members of the PSD95/SAP90 family. The spectrin-NR2B interactions are antagonized by Ca2+ and fyn-mediated NR2B phosphorylation, but not by Ca2+/calmodulin (CaM) or by Ca2+/CaM-dependent protein kinase II-mediated NR2B phosphorylation. The spectrin-NR1 interactions are unaffected by Ca2+ but inhibited by CaM and by protein kinase A- and C-mediated phosphorylations of NR1. Finally, in rat synaptosomes, both spectrin and NR2B are loosened from membranes upon addition of physiological concentrations of calcium ions. The highly regulated linkage of the NMDA-R to spectrin may underlie the morphological changes that occur in neuronal dendrites concurrently with synaptic activity and plasticity.
