Project description:Colon cancer (CRC) and chronic inflammatory bowel disease (IBD) are two common gastrointestinal diseases that have a high impact on the quality of life of the affected individuals and their families as well as on the society. The aim of the present study was to contribute to the understanding of the underlying biological mechanisms of how abcb1 affects the development of colitis and potential environmental interactions. Additionally, we want to form a basis for future studies using the abcb1/mdr1a knockout model. Therefore, we characterized the model using quantitative mass spectrometry based proteomics of colon, ileum and urine as well and gut microbiota by Next-Genome-Sequencing (16SRNA). Additionally, we evaluated the effect of an environmental factor, intake of red meat, using this model.
