GAD1 and Alzheimer disease: The results showed that four miRNAs (miR-192-5p, miR-484, miR-21-5p, and miR-24-2-5p) were downregulated, while two target RNAs (SLC32A1 and GAD1) were upregulated.<h4>Discussion</h4>This regulatory network, which is strongly linked to AD, has been initially identified as a candidate biomarker for AD.
