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

Long non-coding RNAs (lncRNAs) are involved in many neurological conditions, and neurodegenerative disorders including Alzheimer's disease (AD) regulate gene expression at transcriptional, post-transcriptional, and epigenetic levels. However, the roles of lncRNAs in the pathogenesis of AD remain unclear. In this study, we aimed to determine the expression of lncRNAs and also mRNAs in AD which may alter expression and contribute to the pathogenesis of the disease. Peripheral blood samples were obtained from patients admitted to the Neurology Department of Pamukkale University Medical Faculty (23 patients with AD, 33 control groups). Total RNA obtained from peripheral blood mononuclear cells (PBMC) of subjects with probable AD (n = 4) and healthy control groups (n = 4) was examined to determine the altered expression of lncRNAs and mRNAs in AD were evaluated by microarray analysis. Five lncRNAs with the highest end-to-end fold change (fc ≥ 2.0, p < 0.05) were identified and confirmed by quantitative real-time polymerase chain reaction (qRT-PCR). In our study, the profiles of lncRNAs and mRNAs that may be associated with Alzheimer's disease were determined. A total of 14 lncRNAs and 35 mRNAs were determined as upregulated, and 20 lncRNAs and 73 mRNAs determined as downregulated as a result of microarray analysis in patients with AD compared with control groups (fold change ≥ 2.0, p < 0.05). From lncRNAs, expression of lncRNA TTC39C-AS1, lnc-AL445989.1-2, LINC01420, lnc-CSTB-1, and LOC401557 was confirmed by qRT-PCR. When assessed by KEGG analysis of AD PBMC lncRNA and mRNA profiles, TNF signaling pathway, PI3K/AKT, Ras, and MAPK pathways; glutamatergic, dopaminergic, and cholinergic synapses; GABA, and neurotrophin signaling pathways are found to be significant. This is the first known study to investigate lncRNA profiles in AD PBMCs. We think that these results may open a door to the understanding of AD pathogenesis targeted by lncRNAs.
