Bovine follicular development is among the highly orchestrated and dynamically regulated processes affected by multitude of genes expressed in spatio-temporal manner. The emergence of miRNAs as posttranscriptional gene regulators added another layer of complexity into the regulation of follicular development. Despite the growing number of miRNAs reported in several mammalian species and diverse tissue types, little is known about the expression signature and functional role of miRNAs in bovine follicular development. The main goal of the study was to investigate the expression profile and the functional role of miRNAs in granulosa cells of preovulatory dominant and subordinate follicles. Our result showed that the preovulatory dominant and subordinate follicles have unique miRNAs expression signature and miRNA clusters involved in cell proliferation and cell cycle transition are preferentially upregulated in the preovulatory follicles. This suggests these miRNA clusters are involved in the regulating proapoptotic genes and promote cell survival.
