Project description:Although periodontitis is a widespread disease, its molecular mechanisms in human oral cells are not fully understood. Therefore, we established cell lines from the human oral cavity, including gingival keratinocytes (GK), osteoblastic lineage cells from the alveolar bone (OLAB), PDL fibroblasts (PDLF) and cementum cells (CC). Using label-free quantitative mass spectrometry, we investigated changes of the proteome of healthy human oral cells after co-cultivation with Aggregatibacter actinomycetemcomitans and Eikenella corrodens for 24 h, for the first time. Our findings show specific protein profiles for each of the human oral cell lines. This will help to understand pathologic mechanisms in periodontitis and related diseases, such as rheumatoid arthritis, diabetes mellitus or atherosclerotic vascular diseases.

A multicenter translational biomarker phase II trial of regorafenib in patients with non-resectable pretreated colorectal cancer.

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).
