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 applied DNA content flow cytometry to pancreatic ductal adenocarcinoma (PDAC) biopsies. We interrogated purified sorted tumor fractions with whole genome copy number variant (CNV) and next generation sequencing (NGS) analyses. These identified a variety of somatic genomic lesions targeting genes and cellular pathways in PDAC. Of significant interest are lesions that may affect responses to therapies.
Project description:Dicer sequencing was performed on the Illumina MiSeq System in a total of 16 BCC samples (8 nodular BCCs / 8 sBCCs) and mapped against the human reference genome (hg19). Dicer sequencing was performed in all 16 BCC samples. Whole genome methylation profiling performed with Infinium MethylationEPIC BeadChips as well as RNA and smallRNA sequencing were performed in 5 sBCCs with the Illumina NextSeq500 next generation sequencing system. We identified a variety of Dicer mutations that could play a role in aberrant miRNA expression in BCC. The aforementioned RNA sequences should be further evaluated in functional studies towards their possible pathogenetic role in sBCC.

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:Background: Chromatin immunoprecipitation combined with genome tile path microarrays or deep sequencing can be used to study genome-wide epigenetic profiles and the transcription factor binding repertoire. Although well studied in a variety of cell lines, these genome-wide profiles have so far been little explored in vertebrate embryos. Principal findings: Here we report on two genome tile path ChIP-chip designs for interrogating the Xenopus tropicalis genome. In particular, a whole-genome microarray design was used to identify active promoters by close proximity to histone H3 lysine 4 trimethylation. A second microarray design features these experimentally derived promoter regions in addition to currently annotated 5’ ends of genes. Conclusions: A whole-genome and a dedicated promoter microarray design was developed which can be used to study epigenetic phenomena and transcription factor binding in developing Xenopus embryos.
