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

We have previously described the transcriptional changes that occur in the hippocampal CA1 field of aged rats following a Morris Water Maze (MWM) training paradigm. In this report we proceed with the analysis of the dentate region from the same animals. Animals were first identified as age learning-impaired or age-superior learners when compared to young rats based on their performance in the MWM. Messenger RNA was isolated from the dentate gyrus of each animal to interrogate Affymetrix RAE 230A rat genome microarrays. Microarray profiling identified 1129 genes that were differentially expressed between aged and young rats as a result of aging, and independent of their behavioral training (p<0.005). We applied Ingenuity Pathway Analysis (IPA) algorithms to identify the significant biological processes underlying age-related changes in the dentate gyrus. The most significant functions, as calculated by IPA, included cell movement, cell growth and proliferation, nervous system development and function, cellular assembly and organization, cell morphology and cell death. These significant processes are consistent with age-related changes in neurogenesis, and the neurogenic markers were generally found to be downregulated in senescent animals. In addition, statistical analysis of the different experimental groups of aged animals recognized 85 genes (p<0.005) that were different in the dentate gyrus of aged rats that had learned the MWM when compared to learning impaired and a number of controls for stress, exercise and non-spatial learning. The list of learning-related genes expressed in the dentate adds to the set of genes we previously described in the CA1 region. This long list of genes constitutes a starting tool to elucidating the molecular pathways involved in learning and memory formation.
