library_construction_protocol: The mice hippocampi were collected in RNAlater (ThermoFisher Scientific). Individual tissue samples were lysed and homogenized in 850 µl of TRI Reagent (ThermoFisher Scientific) using the Tissue-Lyzer (Qiagen). Total RNA was isolated from the tissue lysate using MagMax 96 microarray kit (AM1839, Life Technologies) according to the manufacturer's instructions. RNAseq libraries derived from poly(A)-selected RNA were isolated from total RNA using the Universal Plus mRNA-Seq kit ((NuGen Technologies/Tecan) according to the manufacturer recommendations.
