Abstract

MicroRNAs (miRNAs) are small non-coding endogenous RNA molecules that down-regulate the expression of target genes in a sequence-dependent manner. Recent studies indicated that miRNAs are mechanistically involved in the regulation of the mammalian corpus luteum (CL). However, few studies have profiled the different miRNA expression patterns in bovine non-regressed and regressed CL. In this study, miRNA microarray was employed to investigate the different miRNA expression patterns in bovine CL. Among the 13 differentially expressed miRNAs, seven were preferentially expressed in non-regressed CL, while six miRNAs were more highly expressed in regressed CL. Real-time RT-PCR was used to validate the microarray results. Mir-378 miRNA, known to be associated with apoptosis, was 8.54-fold (P < 0.01) up-regulated in non-regressed CL, and the interferon gamma receptor 1 (IFNGR1) gene, which potentially plays a role in apoptosis of the luteal cell, was predicted to be the target of mir-378. The results of real-time RT-PCR of mir-378 and western blot analysis of the IFNGR1 protein at different stages of CL development showed that mir-378 decreased the expression of IFNGR1 protein but not IFNGR1 mRNA. Taken together, our data support a direct role for miRNA in apoptosis of bovine CL.
