ABSTRACT
Objective To detect the expressions of circulating microRNAs (miRNAs) of peripheral whole blood in Alzheimer's disease (AD) and investigate the potential roles of the miRNAs as diagnostic bi omarkers for Alzheimer's disease.Methods Peripheral blood samples were obtained from 110 AD patients and 150 age-and gender-matched normal controls.The concentrations of seven candidate miRNAs,including miR-9,miR-29a,miR-29b,miR-101,miR-181c,miR-137and miR-126,were measured with a real-time quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) method.The data of two groups were collected and analyzed by SPSS 19.0 software.Results It was found that miR-29a (P=1.12×10-5) and miR-101 (P=6.24× 10-7) were markedly down-regulated in peripheral blood of AD patients compared with normal controls.In addition,logistic regression analysis revealed peripheral whole blood miR-29a/101 combination could be a potential biomarker of AD with better specificity (82%) and sensitivity (75%).Conclusions miR-29a/101 combination in peripheral whole blood may serve as a useful noninvasive diagnostic biomarker for AD.
