Abstract

Discovered in the brains of multiple animal species, piRNAs may contribute to the pathogenesis of neuropsychiatric illnesses. The present study aimed to identify brain piRNAs across transcriptome that are associated with Alzheimer's disease (AD). Prefrontal cortical tissues of 6 AD cases and 6 controls were examined for piRNA expression levels using an Arraystar HG19 piRNA array (containing 23,677 piRNAs) and genotyped for 17 genome-wide significant and replicated risk SNPs. We examined whether piRNAs are expressed differently between AD cases and controls and explored the potential regulatory effects of risk SNPs on piRNA expression levels. We identified a total of 9453 piRNAs in human brains, with 103 nominally (p < 0.05) differentially (>1.5 fold) expressed in AD cases versus controls and most of the 103 piRNAs nominally correlated with genome-wide significant risk SNPs. We conclude that piRNAs are abundant in human brains and may represent risk biomarkers of AD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
