Project description:Primary objectives: The primary objective is to investigate circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).
Primary endpoints: circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).
Project description:We couple long-read sequence assembly, full-length cDNA sequencing, and a multi-platform scaffolding approach to produce ab initio chimpanzee and orangutan genome assemblies where most genes are complete, gaps are closed, and novel gene models are identified. We further analyzed the overlap between structural variants in the human genome and gene expression differences in human and chimpanzee cells, including iPS-derived organoid radial glia cells.
Project description:Multiomics of faecal samples collected from individuals in families with multiple cases of type 1 diabetes mellitus (T1DM) over 3 or 4 months. Metagenomic and metatranscriptomic sequencing and metaproteomics were carried out, as well as whole human genome sequencing. Phenotypic data is available.
Project description:Interventions: Analysis of bacteremia after ESD of the colon.
Primary outcome(s): Identification of bacteremia after ESD testing blood culture and 16SrRNA gene sequencing.
Study Design: Single arm Non-randomized
Project description:Intra-specific polymorphism in copy number is documented in many organisms, including human and chimpanzee, but very little is known for other great apes. This study aims to provide CNVs data for orangutan, gorilla, bonobo and chimpanzee, and compare the CNV patterns among these species, as well as with human CNVs and segmental duplications from public databases.

Project description:Investigation of whole genome gene expression level changes in hepatocellular carcinoma cell line hepG2 in regular culture, hepG2-slug in regular culture and hepG2-slug on Matrigel. Whole genome gene expression level changes have been compared in hepatocellular carcinoma cell line hepG2 in regular culture, hepG2-slug in regular culture and hepG2-slug on Matrigel.
Project description:We performed genomic sequencing of whole-genome amplified DNA and native DNA isolated during growth in one of five conditions. We sequenced the DNA using Oxford Nanopore and compared the signals from the whole genome amplified DNA to the native DNA to infer sites at which the native DNA was methylated. The file names here are denoted via the strain name (SC419, SC452, or SC469), the growth condition (37C M9, 42C M9, 25C M9, rich media LB, 96 hours of growth), and in two cases, the replicate culture (M9_rep1 and M9_rep2)
Project description:Recent studies have highlighted the large diversity of malaria parasites infecting African great apes (subgenus Laverania) and their strong host specificity. Although the existence of genetic incompatibilities preventing the cross-species transfer may explain host specificity, the existence of vectors with a high preference for a determined host represents another possibility. To test this hypothesis, we undertook a 15-mo-long longitudinal entomological survey in two forest regions of Gabon, where wild apes live, at different heights under the canopy. More than 2,400 anopheline mosquitoes belonging to 18 species were collected. Among them, only three species of Anopheles were found infected with ape Plasmodium: Anopheles vinckei, Anopheles moucheti, and Anopheles marshallii Their role in transmission was confirmed by the detection of the parasites in their salivary glands. Among these species, An. vinckei showed significantly the highest prevalence of infection and was shown to be able to transmit parasites of both chimpanzees and gorillas. Transmission was also shown to be conditioned by seasonal factors and by the heights of capture under the canopy. Moreover, human landing catches of sylvan Anopheles demonstrated the propensity of these three vector species to feed on humans when available. Our results suggest therefore that the strong host specificity observed in the Laveranias is not linked to a specific association between the vertebrate host and the vector species and highlight the potential role of these vectors as bridge between apes and humans.
