Project description:We developed a hybrid-sequencing workflow, combining next-generation and third-generation sequencing, to reconstruct full-length transcriptomes. Integrating with polysome profiling and ribosome footprinting data, we predicted isoform–specific translational status and reconstructed ORFeome. Moreover, we identified isoforms with specific subcellular localization pattern in neurons.
Project description:During development, the inherited DNA methylation patterns from the parental gametes needs to be remodeled into a state compatible with embryonic pluripotency. In Zebrafish, this remodeling is achieved by the maternal methylome becoming hypomethylated to match the paternal methylome. However, how this is achieved in medaka (another teleost fish) is currently not known. Moreover, how DNA methylation remodeling is impacted in hybrid organisms, and the effects this may have on their development, is also not known. Here we address these questions by generation whole genome bisulfite sequencing data for zebrafish, medaka and zebrafish medaka embryos.
Project description:Next Generation Sequencing in cancer: a feasibility study in France to assess sample circuit and to perform analyzes within a limited time.
Project description:We report the expression pattern of placental transcriptome by Next Generation Sequencing from Gestational D19 mouse exposed to Air -Pollutant material with or without prior treatment with Fish Oil.
Project description:In this study, we used next-generation sequencing technologies and tandem mass tags to characterize mRNA-seq, miRNA-seq and proteomic of Pelteobagrus fulvidraco, P. vachelli and hybrid yellow catfish Huangyou-1 (P. fulvidraco female ×P. vachelli male) livers and in doing so, offer deeper insight into the transcriptional and protein changes in heterosis uncovers key roles for miRNAs.
Project description:Heterosis is a complex biological phenomenon in which hybridization exhibits superior phenotypic characteristics. The underlying molecular basis for heterosis, particularly for fishes, remains elusive. The utilization rate of fish heterosis far exceeds our understanding of it on a theoretical level. To gain a comprehensive and unbiased molecular understanding of fish heterosis, we characterized mRNA-seq, miRNA-seq, and proteomes of Pelteobagrus fulvidraco, P. vachelli, and the hybrid yellow catfish Huangyou-1 (P. fulvidraco ♀×P. vachelli ♂) livers using next-generation sequencing technologies and tandem mass tags. Our results show that the nonadditive, homoeologue expression bias and expression level dominance pattern were readily identified in transcriptional, post-transcriptional, or protein levels, providing the evidence for the widespread presence of dominant models during hybridization. At the same time, a number of miRNA-mRNA-protein pairs were found and validated by qRT-PCR and parallel reaction monitoring assays.
Project description:In order to clarify the mechanism to MYC (8q24) amplification as dmin or hsr, we finely investigated the organization of amplicons in seven tumor cell lines [four SCLC, one AML, and two Colon Carcinoma (CC)] by integrating next-generation sequencing (NGS), Fluorescent in situ hybridization (FISH), PCR, and array-based approaches.
Project description:The objective of this study is to optimize the search by next-generation sequencing (NGS) mutations in the KRAS, BRAF and NRAS on circulating tumor DNA and compare the genetic profiles obtained with those from tumors embedded in paraffin
