Project description:The goal of this study was to evaluate the transcriptional response of 4 human duodenal enteroid lines on monolayers to norovirus infections (GII.4). Enteroids were plated as monolayers in Intesticult (Stem Cell Technologies) proliferation medium. After 1 day of cell growth as a monolayer, the proliferation medium was changed with differentiation medium for 5 days. Five-day-differentiated monolayers were washed and were either mock-infected or inoculated with human norovirus supplemented with 500 μM glycochenodeoxycholic acid (GCDCA), for 1 to 2 h at 37°C. Total RNA was extracted using the Qiagen RNeasy kit and paired-end Illumina sequencing was performed.
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).
