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:DNA methylation 5mC specific detection has been limited by the mixed signals from traditional bisulfite sequencing or by the severe degradation of input during oxBS-seq pretreatment. Here, we presented a 5mC specific whole genome amplification method (5mC-WGA), with which we achieved whole genome bisulfite sequencing with 5mC retention from limited input down to 10 pg scale without 5hmC signals, presenting DNA 5mC methylome with high producibility and great accuracy.
Project description:Comparative genomic hybridization of 9 Norwegian E. faecalis baby isolates with E. faecalis V583 as a reference strain using an E. faecalis V583 oligo array. Total gene content was analyzed by whole genome microarrays.
