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)
Long non-coding RNAs (lncRNAs) as a key group of non-coding RNAs have gained widely attention. Though lncRNAs have been functionally annotated and systematic explored in higher mammals, few are under systematical identification and annotation. Owing to the expression specificity, known lncRNAs expressed in embryonic brain tissues remain still limited.(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)
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)
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)
The function of long noncoding RNAs (lncRNAs) in cell differentiation and development have begun to be revealed in recent years. However, the expression pattern and mechanisms regulating lncRNAs are largely unknown during mammalian preimplantation development. LncRNAs expressed from Dlk1-Dio3 imprinted region have been linked to pluripotency of induced(More)
MicroRNAs are small noncoding RNAs involved in various biological processes. We characterized the expression of miR-344-3p during mouse embryonic development. At E9.5–E10.5 and E15.5, in situ hybridization detected strong miR-344-3p signal in the central nervous system, including the cerebral cortex, hindbrain, cerebellum, thalamus, hindbrain, medulla(More)
Most imprinted genes are concerned with embryonic development, especially placental development. Here, we identified a placenta-specific imprinted gene Qpct. Our results show that Qpct is widely expressed during early embryonic development and can be detected in the telecephalon, midbrain, and rhombencephalon at E9.5b-E11.5. Moreover, Qpct is strikingly(More)
