Reduced expression of hsa-miR-27a-3p in CSF of patients with Alzheimer disease

Abstract

Objective We evaluated microRNAs (miRNAs) as potential biomarkers for Alzheimer disease (AD) by analyzing the expression level of miRNAs in CSF of patients with AD dementia and nonaffected control subjects. Methods Using quantitative PCR, we profiled the expression level of 728 miRNAs in CSF of nonaffected control subjects and patients with clinically ascertained AD dementia, and we further compared the expression level of candidate miRNAs in 37 control subjects and 35 patients with AD dementia. Results The level of hsa-miR-27a-3p in CSF is reduced in patients with dementia due to AD in 2 different cohorts of subjects (cohort 1: p = 0.008; cohort 2: p = 0.015; 2-tailed unpaired Welch t test). Moreover, low levels of hsa-miR-27a-3p were accompanied by high CSF tau levels and low CSF β-amyloid levels. Conclusions Our pilot study highlights hsa-miR-27a-3p as a candidate biomarker for AD and provides the groundwork for further confirmation studies in larger cohorts and in other hospitals.

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.
