Dmd and SAP97 are novel targets of miR-9-3p. A, Bioinformatic analyses identified highly conserved miR-9-3p target sequences within Dmd 3′ UTR. B, The Dmd protein level was significantly increased in the hippocampi overexpressing miR-9-3p sponge (n = 7, AAV-control sponge; n = 8, AAV-miR-9-3p sponge, unpaired 2-tailed t test, *p < 0.05). C, The Dmd protein level was not changed by miR-9-5p inhibition (n = 4, AAV-control sponge; n = 4, AAV-miR-9-5p sponge, unpaired 2-tailed t test). D, Bioinformatic analyses identified highly conserved miR-9-3p target sequence within SAP97 3′ UTR. E, The SAP97 protein level was significantly increased in hippocampi overexpressing the miR-9-3p sponge (n = 5, AAV-control sponge; n = 4, AAV-miR-9-3p sponge, unpaired 2-tailed t test, **p < 0.01). F, The SAP97 protein level was not changed by miR-9-5p inhibition (n = 4, AAV-control sponge; n = 4, AAV-miR-9-5p sponge, unpaired 2-tailed t test). Data are mean ± SEM.
