Project description:Within this study, the non-model organism Myriophyllum spicatum was used to evaluate ecotoxic modes of action at the gene expression level. M. spicatum was exposed to low-effect concentrations of bentazone and atorvastatin in a shortened and modified version of the OECD guideline test No. 239, followed by RNA extraction of the shoot tip tissue and a subsequent RNA-seq analysis utilizing a de novo assembly of the transcriptome. While the herbicide bentazone is an inhibitor of photosynthesis, the widely spread pharmaceutical atorvastatin acts as an inhibitor of the hydroxymethylglutaryl-CoA reductase and thus the isoprenoid biosynthesis. The aim of this study was to determine molecular fingerprints and biomarkers distinguishing these distinct modes of action at a molecular level.
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).
