FIGURE 1 miRNAs are differentially expressed in AD compared to control and HPC brains. (A) Workflow of miRNA candidate discovery. RNA was isolated from cortical brain tissue of individuals who were cognitively intact (n = 5), AD (n = 5) or HPC (n = 5) (see Table 1 for demographic data). RNA from the 5 control, 5 AD or 5 HPC brains were pooled and used as template for cDNA synthesis. cDNA from pooled control, AD or HPC were used as templates for qRT-PCR. (B) Comparative analysis of profiled miRNAs between disease groups. miRNAs that are upregulated (red) and downregulated (blue) by >2-fold are indicated. Each point represents log10(2-ΔΔCt) average values from each cDNA pool run in triplicate (3 plates). (C) miRNAs that were significantly altered by >2-fold. A total of 16 miRNAs were dysregulated in AD brains compared to control or HPC brains. Six of those miRNAs were consistently altered specifically in AD brains (miR-608, -219a-5p, 1304-5p, -182-5p, -566, -591). Six additional miRNAs were upregulated >2-fold in AD brains compared to control, but <2-fold compared to HPC brains (miR-32-5p, -519e-5p, 132-3p, 212-3p, -662, -138-3p). Red text = upregulated miRNAs; blue text = downregulated miRNAs.

FIGURE 2 miRNA validation in AD brain tissue by qRT-PCR. miRNA candidates were measured by miRNA-specific qRT PCR. (A) Neuron-specific miR-9 levels, which was similar between disease groups in array analysis, were also unchanged by qRT-PCR [X2(2) = 0.5263, p = 0.769]. Two of the original hits (B) miR-182-5p (∗∗ = 0.009) and (C) miR-32-5p (control vs. HPC, ∗ = 0.049; control vs. HPC, ∗ = 0.025) identified by miRNA arrays were validated by qRT-PCR. (D) miR-132-3p was significantly changed between disease groups [X2(2) = 6.156, p = 0.046], but did not reach statistical significance in pair-wise comparisons. (E) MiR-219a-5p showed a strong trend for change between the three disease groups [X2(2) = 5.906, p = 0.051]. (F) miR-212-3p levels were not significantly changed between disease groups. Fold change was determined by 2–ΔΔCt relative to miR-16. Significance was determined by Kruskal–Wallis test followed by Dunn‘s post hoc test.

FIGURE 3 miRNA analysis of brain-derived exosomes in blood. (A) C(t) values for neuron-specific miR-9, plasma abundant miR-451a, and ubiquitously expressed miR-16 from induced neuronal (iNs) cell lysates (CL), and iN exosomes isolated by ultracentrifugation of iN conditioned medium. (B) Flow chart for the detection of miRNAs from plasma exosomes. RNAs were isolated from total plasma exosomes (Exoquick pellets), or neural exosomes immunoprecipitated (IP) from total plasma exosomes with anti-L1CAM antibody. RNA was reverse transcribed with Qiagen’s HiFlex buffer to generate cDNAs, and subsequently used as template for qPCR using miRNA-specific primers for miRNA detection. C(t) values for miR-9, miR-451a, and miR-16 from (C) plasma-derived total- and L1CAM (L1)- immunoprecipitated exosomes. As a negative control, an irrelevant antibody, 46-4 was used for immunoisolation. Total and IP’ed exosomes were isolated in duplicate (#1 and #2) from 2 healthy control donors (Plasma 1 and plasma 2). Low Ct values indicate high levels of miRNA, and high Ct values indicate low levels of miRNA. The reliable CT limit is ∼40.

FIGURE 4 miR-132/212 is significantly decreased in AD neural exosomes isolated from plasma. (A) neural-specific miR-9 was abundantly detected in all measured samples and was not significantly different between disease groups [X2(2) = 1.195, p = 0.550]. (B) non-specific miR-451a were also detected in samples, but was unchanged between disease groups [F(2) = 0.035, p = 0.965]. Of the miRNAs significantly altered in AD brains, (C) miR-132 was significantly decreased in neural-derived plasma exosomes from AD subjects (∗∗ = 0.0333). (D) miR-212, a miRNA transcribed in tandem to miR-132, was also significantly decreased in AD (∗∗∗ = 0.001). Significance was determined by one-way ANOVA followed by Tukey‘s post hoc test for normally distributed data. Otherwise, Kruskal–Wallis test followed by Dunn‘s post hoc test was used.

FIGURE 5 Receiver-operator-characteristics (ROC) curves demonstrate that miR-132 and miR 212 in neural exosomes evidence good separation between NCI and AD. ROC curves of (A) miR-132, and (B) miR-212 allowed good separation of NCI from AD patients. Neither (C) miR-132, nor (D) miR-212 levels in NCI vs. AD-MCI patients allowed good separation. Area under the curves (AUC) for all ROC analyses were calculated using a non-parametric approach.

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.
