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: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:We report on the genome-wide distribution pattern of histone H3 lysine 9 acetylation (H3K9ac) and the pattern’s association with whole genome expression profiles in Populus trichocarpa subjected to soil-water depletion. We identified a set of drought responsive genes whose expression is directly regulated by differential modification of H3K9ac.

Project description:Investigation of whole genome gene expression level changes in leaves of apple seedlings (Golden delicious) 3 days after treatment by Bion 50WG (ASM) versus water.
Project description:The proteome of the SS13 isolate assigned to the Chromatiaceae family was assessed by shotgun proteomics using a pan-proteomics database for the genus Rheinheimera and a whole genome sequencing -derived database.
Project description:Study hypothesis: We hypothesise that both colon inflammation and a diet high in red meat increase the endogenous formation of potentially carcinogenic N-nitroso compounds in the human colon and that these compounds increase the colorectal cancer risk, which could (partially) explain the increased colorectal cancer risk that is associated with inflammatory bowel disease and diets high in red meat.
Inflammatory bowel disease is characterised by a chronic inflammation within the gastrointestinal tract, which, in case of ulcerative colitis, is present in the colon and rectum.
Primary outcome(s): 1. Whole genome gene expression modifications by microarray analysis (4x44K Agilent platform)
2. Apparent total nitroso compounds in faecal matter by thermal energy analysis
3. Faecal water genotoxicity (30 minute exposure to 10% faecal water) by comet assay analysis in the adenocarcinoma cell line Caco-2
All outcomes are measured at baseline and post intervention.
