Project description:In euakryotes, mRNAs must be exported from the nucleus to the cytsoplasm. NXF2 is highly expressed in the mouse male germ cells. We are interested in its function in spermatogenesis, espically in the nuclear RNA export in the testis. To this end, we made Nxf2 mutant mice by gene targeting. In an attempt to identify the mRNA substrates of NXF2, we perform the microarray experiments on testes. We used microarrays to check the expression profiles of the Nxf2 WT and KO 21d testes on C57BL/6 background. Experiment Overall Design: To examine the expression difference between WT and Nxf2 KO testes, we collected testes from juvenile mice of three ages ( 21d, 26d, 28d). Testis weight was similar between WT and KO mice at post-natal day 21. Three pairs of WT and KO 21d testes were chosen for microarray analysis.
Project description:SOX3 is highly expressed in spermatogonial stem cells within the post natal mouse testes. A ChIP-Seq experiement was performed for SOX3 in postnatal day 7 testes.
Project description:Wild type C57Bl/6J, Cyp1b1-null, and a substrain of Cyp1b1-null that are resistant to diet-induced obesity (Resistant Cyp1b1-null) timed mated pregnant dams were administered either a defined vitamin A sufficient diet or matched vitamin A deficient diet from embryonic day 4.5. Offspring liver gene expression was examined at birth (post-natal day 0) and at weaning (post-natal day 21).
Project description:Tthis study is aimed to explore how C1qbp deficiency affects the mRNA expressing profiling during the differentiation stage of CD8+ T cells.Naïve WT and C1qbp KO P14 cells and transferred WT and C1qbp KO P14 cells sorted from the spleen of donor mice on day 3, 5, 7 post-infection with LCMV Armstrong were collected and treated for RNA-seq. RNA-Seq analysis revealed transcriptomic changes between WT and C1qbp KO CD8+ T cells. Naïve WT and C1qbp KO CD8+ T cells showed similar gene expressing profiling. On day 3, 5, 7 post-infection with LCMV Armstrong, WT and C1qbp KO CD8+ T cells showed 341, 1,164 and 437 differentially expressed genes respectively.
Project description:To profile genomic binding sites of NKAPL and examine whether its knockout alters the genome-wide occupancy of the SOX30/HDAC3 protein complex and RNA Pol II in mouse testes, wild-type and Nkapl KO testes at postnatal day 21 were harvested for ChIP-seq.
Project description:Embryonic day (E)12.5 whole murine embryos, E11.5 - E14.5 whole murine embryos, E11.5 - E14.5, post-natal day (P)3 and P35 murine forelimbs, E14.5 brains, and COL1A2-mutant and COL1A2-WT forelimbs were fractionated and specific fractions were analyzed via LC-MS/MS. Aha-enrichment experiments consisted of in vivo protein labeling with azidohomoalanine (Aha) followed by tissue fractionation of the forelimbs and enrichment of labeled ECM proteins from the final IN pellet ('enriched'). 'Unenriched samples', or the background from which newly synthesized proteins were enriched from, were also analyzed via LC-MS/MS.
Project description:Gene experssion was evaluated in the lungs of mice in which beta-catenin was stabilized or knocked out in the SCGB1A1 lineage. Gene expression was assayed on post-natal day 21
Project description:Spermatogenesis is a recurring differentiation process that results in the production of male gametes within the testes. During this process, spermatogonial stem cells differentiate to form spermatocytes, which undergo two rounds of meiotic division to form haploid spermatids. Throughout spermiogenesis, round spermatids elongate to form mature sperm. To profile maturing germ cells during the first wave of spermatogenesis, we generated droplet-based single cell RNAseq from juvenile animals at post-natal day P5-P35 as well as adult animals. Cells were isolated from whole testes. Furthermore, to assay the robustness of the meiotic cell division process, we profiled germ cells of the trans-chromosomal mouse model (Tc1) that carries a copy of the human chromosome 21.
