library_construction_protocol: Briefly, after the hormone challenge, ovaries from animal were directly lysed in Lysis Buffer (DMEM, 13 WU/ml Liberase™ DH, Dnase I). The ovary RNA-seq protocol was based on the well established protocol with Fast RNA-seq Lib Prep Kit V2 (ABclonal). Sequencing libraries were constructed from 500 pg of amplified cDNA using Fast RNA-seq Lib Prep Kit V2 for Illumina (Catalog number: RK20306, ABclonal) according to the manufacturer's instructions.
