Episomal-Persistent DNA in Cancer- and Chronic Diseases – Dr. Timo Bund

RESEARCH PROFILE

The division “Episomal-Persistent DNA in Cancer- and Chronic Diseases” analyzes human patient material for the presence of a novel group of putative pathogens termed Bovine Meat and Milk Factors (BMMFs) which are frequently isolated from bovine meat and milk. These plasmid-related episomal DNA agents are speculated to represent specific long-latency risk factors for the development of several major human diseases like breast and colon cancer as well as neurodegenerative diseases – several of those epidemiologically linked with bovine meat and milk consumption. We recently verified BMMF bioactivity in human cells along with specific modulation of disease-relevant host pathways. In addition, we established a spectrum of diagnostic screening tools allowing detection of putative pathogenic proteins as well as analysis of indicative serological and immunological response patterns.

PROJECT TOPICS

With strong focus on BMMF genome/transcriptome/proteome analysis, the aim of the new research project is the identification of additional disease markers but also specific immunologic analysis of human response upon infection with already known BMMFs. Human cell culture infection models as well as selected animal models are the tools for detailed analysis of BMMF contribution to cancer/disease development, which serves as a milestone for interventions like targeted therapy/vaccination.

In this multifaceted project the successful candidate exploits experimental techniques in the field of immunology, virology as well as molecular biology (e.g. DNA/RNA Sequencing, PAR-CLiP/RACE, mass spectrometry, serological/protein screening assays e.g. WB/NB/IF/IHC/ELISA/FACS). We offer a research project with access to excellent technical facilities and a place in a young, dynamic and creative international team with strong scientific collaborations.

Cellular Polarity and Viral Infection – Dr. Steeve Boulant

RESEARCH PROFILE and PROJECT TOPICS

In my lab, we have been exploiting human intestinal organoids to characterize host/pathogen interactions at the intestinal mucosal barrier. Our work aims at characterizing the cellular mechanisms developed by our intestinal epithelium to combat enteric viruses (norovirus, astrovirus, reovirus) and at identifying the molecular strategies established by these pathogens to interfere with these mechanisms to promote their replication and induce pathogenesis. With the ambition of developing an organoid culture system that better mimics the physiological environment, we are implementing a novel mini-gut culture model that integrates the cellular, biophysical and biochemical parameters naturally encountered in the human gut. We have gathered multiple lines of evidence which demonstrate that the above parameters cannot be ignored when studying host/pathogen interactions as they strongly influence the response of the host during infection. Additionally, our preliminary findings also suggest that this gut-specific micro-environment is key to maintain immuno-homeostasis by promoting partial tolerance of the gut microbiota.

Mammalian Cell Cycle Control Mechanisms – Prof. Dr. Ingrid Hoffmann

RESEARCH PROFILE

Genomic instability is an emerging hallmark of cancer cells. It is a characteristic of almost all human cancers, but at what stage of cancer development
it arises and what its molecular basis is are questions to which we are only beginning to get answers.
When cells divide, it is essential that they segregate their newly duplicated chromosomes into two equal daughter cells. Centrosomes form the spindle poles of the mitotic spindle. Having the correct number of centrosomes at the poles of the mitotic spindle is crucial for proper chromosome segregation during cell division and for the prevention of genomic instability. Errors in centrosome duplication lead to cells with too many centrosomes which is frequently observed in cancer cells. The biochemical pathways underlying centrosome duplication and how this process is dysregulated in cancer are poorly understood.

 

PROJECT TOPICS

The goal of the project is to identify and characterize substrates and binding partners of the master regulator of centrosome duplication, which is the polo-like kinase Plk4. Using phosphoproteomics, biochemical techniques (Co-IP, Bio-ID) and yeast-two hybrid screens we will identify novel candidate substrates/regulators of Plk4.
The most interesting candidates identified will be characterized in further detail with the aim to better understand the mechanism underlying centrosome overduplication in cancer cells.

A variety of state-of-the-art cell biological and biochemical techniques (i.e confocal microscopy, life cell imaging, FRET/FRAP techniques, high-resolution microscopy (SIM) and far-western analysis) will be used.
