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).

Project description:To characterize the site-specific methylation landscape of the Mandarin fish ranavirus (MRV) genome, whole-genome bisulfite sequencing (WGBS) was conducted on an isolated MRV strain.
Project description:We exposed zebrafish embryos to 0.3, 3, and 30 ppb (µg/L) of ATZ for 72 hours post fertilization. We performed whole-genome bisulfite sequencing (WGBS) to assess the effects of developmental ATZ exposure on DNA methylation in female fish brains
Project description:In the study, researchers investigated acral melanomas, particularly subungual melanomas (SUM), which are primarily characterized by whole genome copy number variations (CNV) such as amplifications, gains, and losses. Previous research has utilized various cytogenetic or molecular analyses ranging from targeted methods focused on specific genes to comprehensive whole genome and whole transcriptome sequencing techniques. To differentiate between malignant and benign lesions, fluorescence in situ hybridization (FISH) methods have been commonly employed, utilizing probes targeting genes like CCND1, RREB1, MYB, CDKN2A, or MYC either individually or in combination.In this study a Comparative Genomic Hybridization on array (array-CGH) was performed to detect whole genome CNV. This approach aimed to improve the classification of malignant and benign lesions in a cohort consisting of 31 SUM cases and 8 subungual lentiginous melanocytic proliferations with or without atypia.
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: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:Dnmt1 is a key methyltransferase involved in the maintenance of DNA methylation. To determine whether developmental defects induced by hypomorphic DNA 5-methylcytosine methyltransferase activity can be offset by increasing DNA replication time, we produced fish that were mutant for both dnmt1 and DNA polymerase epsilon (pole1) and compared their whole genome bisultite sequencing and gene expression profiles to WT ones. We further determine that the observed rescue effect by pole1 is specific to dnmt1 by comparing whole-genome bisulfite sequencing and gene expression profiles of mutants for the Methionine Adenosyltransferase 2A (mat2aa) and microchromosome 10 (mcm10)
