| abstractText | Ifrg15 is a newly identified interferon alpha responsive gene and is implicated in a wide variety of physiological roles in mammals. In the present study, multiple alignments of the deduced amino acids of 10 eutherian mammalian IFRG15/Ifrg15s isolated from open genomic database revealed that they were highly conserved. Real-time PCR showed that mouse Ifrg15 mRNA was expressed in MII stage oocytes and preimplantation embryos, and its highest value peaked at the stage of mouse blastocysts. To understand the effect of three development-related genes on the promoter activity of mouse Ifrg15, promoter analysis using luciferase assays in COS-7 cells were performed. The results showed that the transcription of mouse Ifrg15 was suppressed by Oct4 and Nanog when transfected with the longest Ifrg15 promoter reporter gene. After the relatively shorter promoters were co-transfected with Oct4, c-Myc and Nanog, the relative luciferase activities of Ifrg15 were gradually increased. These in vitro results data and expression profiles of Ifrg15 as revealed by real-time PCR partly indicated that Ifrg15 transcription might be either potentially regulated or dependent on the post-transcriptional effects of IFN-alpha mediated by the three genes indirectly. Our data suggested that the mouse Ifrg15 might interact with these key development-related genes and play significant roles on the mouse preimplantation embryos development, especially for the development of mouse blastocysts. |
