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

A growing number of studies report the expression of olfactory receptors (ORs) in many non-chemosensory tissues and organs. However, within the brain, very few ectopic ORs are exhaustively documented. Their kinetic expression, cellular localization, and functions remain elusive. Using cDNA microarrays, quantitative PCR, and immunohistochemistry, we studied the cellular and sub-cellular localization of Olfr110/111 and Olfr544 and their timely expression in various brain areas of wild-type and transgenic Alzheimer's disease-like (5xFAD) mice. We observed that Olfr110/111 and Olfr544 proteins are mainly expressed by neurons in cortical and hippocampal regions and, to a lesser extent, by astrocytes, microglia, oligodendrocytes, and endothelial cells. In addition, both ORs are present at the cell membrane and co-expressed with the olfactory Gαolf protein, suggesting that they can be functional. Remarkably, we also found that the expression of the mRNA encoding for Olfr110/111 tends to increase with age in both the cortex and hippocampus of wild-type and transgenic mice. Moreover, Olfr110/111 transcript expression is markedly impaired in the brain of Alzheimer's disease-like mice. A different profile is noticed for Olfr544, for which an overexpression is observed only in the cortex of 9-month-old animals. In addition, in transgenic mice, olfactory receptors are observed near amyloid plaques. Altogether, our findings indicate that ORs may play a role in brain functioning, in normal and pathological conditions.
