Abstract:
OBJECTIVETo detect the expression of miRNA-135a-5p, miRNA-135a-2-3p, miRNA-298-5p, miRNA-466b-3p and miR-669f-3p in the brain tissue of the APPswe/PS δE9 double transgenic mouse model of Alzheimer's disease using real-time PCR.
METHODSSix-month-old APPswe/PS δE9 double transgenic mice and wild-type C57 mice of the same species were examined for the expressions of miRNA-135a-5p, miRNA-135a-2-3p, miRNA-298-5p, miRNA-466b-3p and miR-669f-3p in the brain tissue using real-time PCR.
RESULTSThe relative expression levels of the 5 miRNAs in the transgenic versus the wild-type mice were 0.73∓0.27 vs 1.08∓0.58, 2.47∓6.15 vs 1.65∓0.67, 0.72∓0.14 vs 1.31∓0.73, 0.57∓0.34 vs 1.06∓0.35, and 0.63∓0.26 vs 1.02∓0.18, respectively, showing significance differences in the expressions of miRNA-135a-5p, miRNA-298-5p, miRNA-466b-3p, and miR-669f-3p between the two groups (P<0.05).
CONCLUSIONSmiRNA-135a-5p, miRNA-298-5p, miRNA-466b-3p and miR-669f-3p are expressed differentially in APPswe/PS δE9 double transgenic mice, suggesting their important roles in the pathogenesis of Alzheimer disease.
