Total hippocampal RNA was isolated during the noted day and night time points, using methods described previously (Hansen et al. 2013 (link)). In brief, after RNA isolation, hippocampal cDNA was prepared using the miScript II Reverse Transcription kit (Qiagen). Amplification of cDNA was carried out using QuantiFast SYBR Green (Qiagen), and the miScript Primer System (Qiagen) was used to quantify miR-132 levels. The following miR-132 primer sequence was utilized: 5′ UAACAGUCUACAGCCAUGGUCG (Qiagen, Cat# MS00001561). QuantiFast SYBR Green thermocycling conditions were previously described by Alemayehu et al. (2013) (link). Data from both time points were normalized to RNU6B_2 cDNA levels, and Double Delta CT was used for analysis.
