library_construction_protocol: Frozen hippocampal tissues were directly homogenized in TRIzol® Reagent (Invitrogen, 15596026) using The Bullet Blender® and silicon beads. Chloroform was used to extract RNA from the homogenate at a volume ratio of 1:5 to that of the TRIzol® Reagent. Ethanol was then used to precipitate nucleic acids from the aqueous phase. RNA was further purified using PureLink™ RNA Mini Kit (Invitrogen™, 12183018A) following manufacturer's instructions. Purelink™ DNase (Invitrogen™, 12185010) was used to eliminate DNA contamination. Purified RNA was eluded in RNase-free, diH2O. RNA concentration and quality were checked by NanoDrop™ One. RNA libraries were prepared for sequencing using standard Illumina protocols
