Transcriptome datasets of gonadotropin-induced ESR2-regulated genes in rat oocytes

Abstract Disruption of estrogen receptor beta (ESR2) dysregulates oocyte maturation, which leads to failure of ovulation. We investigated ESR2-regulated genes during gonadotropin-induced oocyte maturation using RNA-sequencing. Through the administration of pregnant mare's serum gonadotropin (PMSG), synchronized follicle development was initiated in four-week-old wildtype and Esr2-null female rats. Forty-eight hours after the PMSG injection, human chorionic gonadotropin (hCG) was used for further maturation. Oocytes were collected from the ovaries 4 h after hCG injection. The total RNA was isolated from the oocytes and the whole oocyte transcriptome was determined by RNA-sequencing on the Illumina HiSeq4000 sequencer. RNA-sequencing data of wildtype and Esr2-null oocytes were analyzed, and differentially expressed genes were identified using the CLC Genomics Workbench. Whole oocyte transcriptome data of wildtype and Esr2-null oocytes were compared to identify the differentially expressed genes. Raw data are deposited to the NCBI Sequence Read Archive (SRA) and analyzed data are presented in this data article. These datasets can be utilized to identify the gonadotropin-induced genes in oocytes that are ESR2-regulated and important to oocyte maturation.
