Project description:The systematic deep sequencing analysis provided a comprehensive understanding of the transcriptome complexity of 2n and 3n Fujian oyster. This information broadens our understanding of the mechanisms of C.angulata polyploidization and contributes to molecular and genetic research by enriching the oyster database. This is the first report on genome-wide transcriptional analysis of adductor muscle of diploid and triploid Fujian oyster and has demonstrated triploid oysters are morphologically almost identical to their diploid counterparts, but have faster growth, due to the reorientation of energetic allocation from gametogenesis to somatic investment. This study provides a foundation for further analysis of the gene expression patterns and signaling pathways which regulate the molecular mechanisms of diploid and triploid oyster.

Project description:To avoid negative environmental impacts of escapees and potential inter-breeding with wild populations, the Atlantic salmon farming industry has and continues to extensively test triploid fish that are sterile. However, they often show differences in performance, physiology, behavior and morphology compared to diploid fish, with increased prevalence of vertebral deformities and ocular cataracts as two of the most severe disorders. Here, we investigated the mechanisms behind the higher prevalence of cataracts in triploid salmon, by comparing the transcriptional patterns in lenses of diploid and triploid Atlantic salmon, with and without cataracts. We assembled and characterized the Atlantic salmon lens transcriptome and used RNA-seq to search for the molecular basis for cataract development in triploid fish. Transcriptional screening showed only modest differences in lens mRNA levels in diploid and triploid fish, with few uniquely expressed genes. In total, there were 165 differentially expressed genes (DEGs) between the cataractous diploid and triploid lens. Of these, most were expressed at lower levels in triploid fish. Differential expression was observed for genes encoding proteins with known function in the retina (phototransduction) and proteins associated with repair and compensation mechanisms. The results suggest a higher susceptibility to oxidative stress in triploid lenses, and that mechanisms connected to the ability to handle damaged proteins are differentially affected in cataractous lenses from diploid and triploid salmon.

Project description:In pluripotential reprogramming, a pluripotent state is established within somatic cells. In this study, we have generated induced pluripotent stem (iPS) cells from bi-maternal (uniparental) parthenogenetic neural stem cells (pNSCs) by transduction with four (Oct4, Klf4, Sox2, and c-Myc) or two (Oct4 and Klf4) transcription factors. The parthenogenetic iPS (piPS) cells directly reprogrammed from pNSCs were able to generate germline-competent himeras, and hierarchical clustering analysis showed that piPS cells were clustered more closer to parthenogenetic ES cells than normal female ES cells. Interestingly, piPS cells showed loss of parthenogenetic-specific imprinting patterns of donor cells. Microarray data also showed that the maternally imprinted genes, which were not expressed in pNSCs, were upregulated in piPS cells, indicating that pluripotential reprogramming lead to induce loss of imprinting as well as re-establishment of various features of pluripotent cells in parthenogenetic somatic cells. 5 samples were analyzed by microarray, each one them in duplicate. fNSC: Mouse female NSC (Neural Stem Cell) pNSC: Mouse parthenogenetic NSC (Neural Stem Cell) piPS-2F: Mouse parthenogenetic induced pluripotent cells derived from NSC overexpressing Oct4 and Klf4 pESC-B: Mouse parthenogenetic ESC (Embryonic Stem Cell) SSEA-1 sorted fESC: Mouse female ESC (Embryonic Stem Cell) OG2

Project description:Parthenogenetic embryonic stem cells (PESCs) may have future utility in cell replacement therapies. We examined genome-wide mRNA expression profiles of monkey PESCs relative to ESCs derived from fertilized embryos. Several known paternally-imprinted genes were in the highly down-regulated group in PESCs compared to ESCs. Allele specific expression analysis of paternally-imprinted genes, i.e., those genes whose expression is down-regulated in PESCs, led to the identification of one novel candidate that was exclusively expressed from a paternal allele. Our findings suggest that PESCs could be used as a model for studying genomic imprinting and in the discovery of novel imprinted genes. Keywords: gene expression The transcriptomes of rhesus monkey embryonic stem cell lines derived from IVF-produced embryos (Oregon Rhesus Macaque Embryonic Stem, ORMES-22) were compared with rhesus monkey parthenogenetic embryonic stem cell lines (heterozygous rhesus Parthenogenetic embryonic stem cell lines, rPESC-2) and homozygous rhesus Parthenogenetic embryonic stem cell lines, ORMES-9). Moreover, the transcriptomes of rPESC-2 line were also compared with ORMES-9. Finally, the adult somatic skin fibroblasts were analyzed. Three biological replicates of each cell line (A, B, C) were analyzed.

Project description:In this study, mRNA expression profiles were examined by Illumina microarray in mouse embryonic stem cells (ESCs) derived from androgenetic (aESC), parthenogenetic (pESC) and fertilized (fESC) blastocysts. Results showed that 2394, 87 and 1788 mRNAs were differentially expressed in the aESCs vs. fESCs, pESCs vs. fESCs and aESCs vs. pESCs, respectively. Androgenetic, parthenogenetic and fertilized embryonic stem cell lines were established from androgenetic, parthenogenetically activated and fertilized blasotocyst. mRNA microarrays were repeated three times using passages 6, 7 and 8.

Project description:Embryonic stem (ES) cells are used in cell therapy and tissue engineering due to their ability to produce different cells types. However, studies of ES cells that are derived from fertilized embryos have raised concerns about the limitations imposed by ethical and political considerations. Therefore, many studies of ES cells use the ES cells that are derived from unfertilized oocytes and adult tissue. Although parthenogenetic embryonic stem (ESP) cells also avoided ethical and political dilemmas and can be used in cell-based therapy, the ESP cells exhibit growth retardation problems. Therefore, to investigate the potential for muscle growth from genetically modified ESP cells, we established four ES cell types, including normal embryonic stem (ESN) cells, ESP cells, ESP cells that overexpress the Igf2 gene (ESI) and ESP cells with down-regulated H19 gene expression (ESH). Using these cells, we examined the expression profiles of genes that were related to imprinting and muscle using microarrays.
