In the present study, we compared the individual protein expression patterns from histologically characterized PCa and the surrounding benign tissue obtained by manual micro dissection using highly sensitive two-dimensional differential gel electrophoresis (2D-DIGE) coupled with mass spectrometry. Proteomic data revealed 118 protein spots to be differentially expressed in cancer (n = 24) compared to benign (n = 21) prostate tissue. These spots were analysed by MALDI-TOF-MS/MS and 79 different proteins were identified. Using principal component analysis we could clearly separate tumor and normal tissue and two distinct tumor groups based on the protein expression pattern. By using a systems biology approach, we could map many of these proteins both into major pathways involved in PCa progression as well as into a group of potential diagnostic and/or prognostic markers. Due to complexity of the highly interconnected shortest pathway network, the functional sub networks revealed some of the potential candidate biomarker proteins for further validation. By using a systems biology approach, our study revealed novel proteins and molecular networks with altered expression in PCa. Further functional validation of individual proteins is ongoing and might provide new insights in PCa progression potentially leading to the design of novel diagnostic and therapeutic strategies.}, language = {en} } @article{StandfussPospisilKlein2012, author = {Standfuß, Christoph and Pospisil, Heike and Klein, Andreas}, title = {SNP microarray analyses reveal copy number alterations and progressive genome reorganization during tumor development in SVT/t driven mice breast cancer}, series = {BMC Cancer}, volume = {12}, journal = {BMC Cancer}, number = {380}, issn = {1471-2407}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:526-opus4-6414}, pages = {15}, year = {2012}, abstract = {Tumor development is known to be a stepwise process involving dynamic changes that affect cellular integrity and cellular behavior.

The disease is very often diagnosed late. A better understanding of the relationship between the gut microbiome and type 2 diabetes can support early detection and form an approach for therapies. Microbiome analysis offers a potential opportunity to find markers for this disease. Next-generation sequencing methods can be used to identify the bacteria present in the stool sample and to generate a microbiome profile through an analysis pipeline. Statistical analysis, e.g., using Student's t-test, allows the identification of significant differences. The investigations are not only focused on single bacteria, but on the determination of a comprehensive profile. Also, the consideration of the functional microbiome is included in the analyses. The dataset is not from a clinical survey, but very extensive. Results By examining 946 microbiome profiles of diabetes mellitus type 2 sufferers (272) and healthy control persons (674), a large number of significant genera (25) are revealed. It is possible to identify a large profile for type 2 diabetes disease. Furthermore, it is shown that the diversity of bacteria per taxonomic level in the group of persons with diabetes mellitus type 2 is significantly reduced compared to a healthy control group. In addition, six pathways are determined to be significant for type 2 diabetes describing the fermentation to butyrate. These parameters tend to have high potential for disease detection. Conclusions With this investigation of the gut microbiome of persons with diabetes type 2 disease, we present significant bacteria and pathways characteristic of this disease.}, language = {en} } @inproceedings{WelzelHauschultzFriedoetal.2022, author = {Welzel, Felix and Hauschultz, Mike Thomas and Friedo, Maria Helene and Just, Verena and Richetta, Maria and Foitzik, Andreas}, title = {Concept for a Portable Measuring Device for the Quantitative Detection of Legionella}, series = {Open Conference Proceedings}, volume = {2}, booktitle = {Open Conference Proceedings}, publisher = {TIB Open Publishing}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:526-opus4-17616}, pages = {15 -- 17}, year = {2022}, abstract = {According to the drinking water regulation, drinking water systems must be tested for harmful contamination at specified intervals.
