Abstract:
Objective To determine the expression profile of serum microRNAs(miRNAs) in early-onset familial Alzheimer's disease (EO-FAD) patients. methods miRNA microarrays were performed to detect the expression profile of serum miRNAs in 2 cases of EO-FAD patients,2 cases of EO-FAD carriers and 2 cases of normal controls.Preliminary bioinformatic analysis was conducted. Result sIt was found that 21 miRNAs were up-regulated and 22 miRNAs were down-regulated in serum of EO-FAD patients,the differences were statistically significant(P<0.05).miR-5704(P=0.0002),miR-4639-3p(P=0.0195),miR-107(P=0.0204) were markedly up-regulated,miR-5572(P=0.0008),miR-204-3p(P=0.0014),miR-542-5p(P=0.0106) and miR-155-5p(P=0.0240) were markedly down-regulated.Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis suggested that the dysregulated miRNAs may be involved in the mechanism of EO-FAD by affecting neurotrophin signaling pathway.Conclusion miR-5704,miR-4639-3p,miR-107,miR-5572,miR-204-3p,miR-542-5p and miR-155-5p may be used as potential biomarkers of EO-FAD,and involved in the mechanism of EO-FAD by affecting neurotrophin signaling pathway.
