A combined miRNA-piRNA signature to detect Alzheimer’s disease
Open accessAbstract
Alzheimer’s disease (AD) is the most common neurodegenerative disorder causing huge emotional and economic burden to our societies. An effective therapy has not been implicated yet, which is in part also due to the fact that pathological changes occur years before clinical symptoms manifest. Thus, there is a great need for the development of a translatable biomarker. Recent evidence highlights microRNAs as candidate biomarkers. In this study, we use next-generation sequencing to study the small noncoding RNAome (sncRNAome) in exosomes derived from human cerebrospinal fluid (CSF). We show that the sncRNAome from CSF-derived exosomes is dominated not only by microRNAs (miRNAs) but also by PIWI-interacting RNAs (piRNAs). We define a combined signature consisting of three miRNAs and three piRNAs that are suitable to detect AD with an AUC of 0.83 in a replication cohort and furthermore predict the conversion of mild–cognitive impaired (MCI) patients to AD dementia with an AUC of 0.86 for the piRNA signature. When combining the smallRNA signature with pTau and Aβ 42/40 ratio the AUC reaches 0.98. Our study reports a novel exosomal small noncoding RNA signature to detect AD pathology and provides the first evidence that in addition to miRNAs, piRNAs should also be considered as a candidate biomarker for AD.

There has been only one study reporting a combined AUC of 0.98 for p-tau and Aβ42/40 based on CSF ELISA assays, plus a signature of combined 3 miRNAs and 3 piRNAs from CSF deep sequencing.
“Moreover, there has been only one study reporting a combined AUC of 0.98 for p-tau and Aβ42/40 with calculations based on CSF ELISA assays, plus a signature of combined 3 miRNAs +3 piRNAs with scores derived by deep sequencing of RNA isolated from CSF samples (Jain et al., 2019).”

The plasma piRNAs identified in this study did not overlap with those in Jain et al.'s study of EV isolated from CSF.
“The fact that the identified plasma piRNAs in our study didn’t overlap with Jain et al. study performed on EV isolated from CSF (Jain et al., 2019) is not surprising.”

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.
