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)
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)
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)
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)
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)
Long intergenic non-coding RNAs (lincRNAs) as a key group of non-coding RNAs have gained substantial attention. Though lincRNAs have been systematically explored in various mouse tissues and cell lines, large-scale identification of lincRNAs in mouse pre-implantation embryonic development (PED) process has not be documented previously. Therefore, it is(More)
As the regulatory factors, lncRNAs play critical roles in embryonic stem cells. And lincRNAs are most widely studied lncRNAs, however, there might still might exist a large member of uncovered lncRNAs. In this study, we constructed the de novo assembly of transcriptome to detect 6,701 putative long intergenic non-coding transcripts (lincRNAs) expressed in(More)
