Abstract

Controlled ovarian stimulation plays an integral role in assisted reproduction technology, but individual patients have different responses to exogenous gonadotropins. In order to determine whether microRNAs (miRNAs) have a regulatory role in ovarian response, we profiled the expression of microRNAs in isolated ovarian granulosa cells collected from ovarian hyperresponders and normal responders using microarrays and validated the expression of selected miRNAs using quantitative polymerase chain reaction (PCR). There were 81 miRNAs differentially expressed between the 2 groups, with 45 increased and 36 decreased in the high response group. Bioinformatics analysis of these altered miRNAs and their target genes revealed some significantly enriched pathways, including regulation of the cell cycle, transcription, cell proliferation, and gonadotrophin releasing hormone signaling pathway. The expression of hsa-miR-513a-5p, hsa-miR-27b-3p, hsa-miR-19b-3p, hsa-miR-3201, hsa-miR-423-5p, hsa-miR-193b-5p, and hsa-miR-202-3p was validated by real-time PCR. Hsa-miR-423-5p, predicted to target anti-Mullerian hormone, cytochrome P450, family 19, subfamily A, polypeptide 1, methylenetetrahydrofolate reductase, progesterone receptor, and follicl...Continue Reading

Cell Cycle Pathways

Cell cycle is a complex process regulated by several signal transduction pathways and enzymes. Here is the latest research on regulation of cell cycle and cell cycle pathways.
