The effect of FSH on goat follicular development, granulosa cell apoptosis and steroidogenesis and its mediation by insulin-like growth factor (IGF)-I were studied through both in vivo and in vitro experiments. The FSH treatment was begun on Day 9 after estrus and consisted of injections twice a day for 3 days in decreasing doses (7.5-7.5-5.0-5.0-2.5-2.5(More)
Recent advances of induced pluripotent stem cells (iPSCs) has demonstrated that full development potential is closely related with the expression state of noncoding RNAs (ncRNAs) of the Dlk1-Dio3 imprinted gene cluster. However, few of them, especially the long noncoding RNAs (lncRNAs), have been characterized in detail. AK044800 is a transcript from the(More)
Recent research has revealed that the maternal non-coding RNA genes (Gtl2, Rian and Mirg) from the Dlk1-Dio3 imprinted cluster are closely related to the full development potential of the induced pluripotent stem cells (iPSCs). Transcriptional silencing of these genes failed to generate all-iPSC mice, indicating their significant contribution to(More)
Polo-like kinase 1 (Plk1) is a conserved serine/threonine protein kinase that plays pivotal roles during the cell cycle and cell proliferation. Although a number of important targets have been identified, the mechanism of Plk1-regulated pathways and the bulk of the Plk1 interactome are largely unknown. Here, we demonstrate that Plk1 interacts with the(More)
Non-coding RNAs (ncRNAs) Meg8 and Irm were previously identified as alternatively splicing isoforms of Rian gene. Ascertaining ncRNAs spatiotemporal expression patterns is crucial for understanding the physiological roles of ncRNAs during tissue and organ development. In this study in mouse embryos, we focused on the developmental regulation expression of(More)
Members of the super-class of zinc finger proteins are key regulators in early embryogenesis. Utilizing in silico mining of EST Databases for pre-implantation Embryo-Specific Zinc Finger Protein Genes, we characterized a novel zygotic mouse gene-tripartite motif family-like 1 (TRIML1), which expresses in embryo before implantation. Knocking down of TRIML1(More)
Mouse Trmt112, the homologous gene of yeast Trm112 (tRNA methyltransferase 11-2), was initially cloned from RIKEN with uncertain function. The yeast TRM112 is now known to play important roles in RNA methylation. Here, we studied the expression of Trmt112 by in situ hybridization and quantitative real-time RT-PCR (QRT-PCR). A higher expression level of(More)
Mouse Pde4d is located on chromosome 13 and serves many functions in important physiological processes involving cyclic adenosine monophosphate. In this study, imprinting analysis indicated that Pde4d exhibits a dynamic and specific allelic expression pattern during embryo development. This showed paternal-origin sex bias in embryonic day 9.5 (E9.5) whole(More)
Prelid2, which belongs to the PRELI domain containing family, is identified as a conserved evolution gene. The expression and regulation during embryonic development of the prelid2 gene is unknown. In this study, we investigated the prelid2 gene expression and regulation using mouse embryos model, by in situ hybridization analysis, RT-PCR and bisulfite(More)
With readily available transcriptome-wide data, understanding the role of each expressed gene is an essential next step. Although RNAi technologies allow for genome-wide screens in cell culture, these approaches cannot replace strategies for discovery in the embryo. Here we present, for the first time, a knockdown screen in mouse preimplantation embryos.(More)
