S100-induced innate immune programming protects newborn infants from sepsis
Neugeborenen Immunantwort auf Sepsis
Project Investigators: Prof. Dr. Maren von Köckritz-Blickwede
Duration: Mid 2015 until Novemer 2018
Project Details:
Neonatal sepsis is a major risk factor for childhood mortality. The high susceptibility for septic diseases has been linked to immaturity of neonatal innate immunity. This concept primarily refers to experimental studies that found impaired inflammatory responses of neonatal innate immune cells to microbial challenges. However, one hallmark of sepsis in newborns is an extremely rapid course with a hyperinflammatory immune response. This inconsistency of experimental and clinical findings is currently unsolved indicating that the molecular mechanisms of immaturity and postnatal maturation are still unclear.
In this study we demonstrated that high levels of S100 alarmins at birth transiently induced hyporesponsiveness of phagocytes of healthy neonates compared to adult cells upon microbial challenges. The LPS response of human adult and neonatal Mo was inversely regulated resulting in differential expression of MyD88- and TRIF-dependent gene programs. Basal and LPS-induced transcription patterns in neonatal phagocytes were epigenetically regulated and adapted toward the adult phenotype during the first year of life. S100-induced programming prevented overwhelming inflammation but preserved anti-microbial activities of phagocytes. The biological and clinical relevance of this mechanism was confirmed by significantly higher lethality of S100A9-/- mice in a neonatal sepsis model and the association of lower S100A8/A9-concentrations in human neonates with the risk of septic complications. Our findings indicate that postnatal innate immune reprogramming is a vulnerable phase highly relevant for the resistance or susceptibility of newborns to hyperinflammation and septic diseases.
Results:

In neonates S100A8/S100A9 alarmins prevent the expansion of a specific inflammatory monocyte population promoting septic shock.

Molecular characterization of feline mammary tumors
Molekulare Charakterisierung von Mammatumoren der Katze
Project Investigators: I. Nolte; H. Murua Escobar; M. Hewicker-Trautwein; J. Granados-Soler
Duration: Mid 2015 until End 2018
Project Details:
Mammary cancer is the third most common neoplasm in cats with a classification of 80-90 % as malignant highly-aggressive adenocarcinomas. As the median survival time varies from four months to three years depending on tumor size and clinical staging, early diagnosis and treatment gives best prognosis. Potential new molecular markers can provide further prognostic information helping to understand the molecular pathogenesis of the neoplastic change and enable early diagnosis. The prognostic potential of different human and feline mammary cancer-related genes (ER, PR, HER2/neu, EGFR, PI3K, pAkt, PTEN, CDH1, SnaiI, CLDN-2, COX-2, CK5/6, CK14, BRCA1, BRCA2, STAT3) has been investigated, but not the potential interaction of these targets with each other. Some further molecular markers were just analyzed in humans (HMGA2, FOXC1, STAT1), which might also be of importance for the feline disease. Characterization of those targets concerning characteristic expression patterns in correlation with histological grading, gene-regulation and identification of their potential interaction is essential for finding new molecular biomarkers. Besides the characterization of the gene expression pattern, the regulation of the expression and the interaction of potential molecular markers is still a novel field of intensive research in general. Herein, especially microRNAs have moved into the spotlight. Focusing on cats, only little is known about miRNA regulated pathways so far. Consequently further research on the identification of miRNAs playing a role in the regulation of genes being associated to feline mammary carcinomas is important as well to elucidate processes causing tumor development and progression. Aim of this study is to promote the molecular characterization of gene expression patterns and regulatory miRNAs within primary feline mammary carcinoma tissues and cell lines to identify reliable prognostic molecular markers.

Evaluation of single nucleotide variants in canine lymphoma undergoing conventional chemotherapy
Untersuchung von single nucleotide variants im caninen Lymphom während des Verlauf einer konventionellen Chemotherapie
Project Investigators: I. Nolte; H. Murua Escobar; D. Betz; N. Eberle; C. Penter
Duration: Mid 2015 until End 2018
Project Details:
Chemotherapeutic intervention is routinely employed as therapeutic regimen with initial success. However, most canine lymphomas relapse within 12 month indicating that part of the initial lymphoma cells mass is characterized by chemotherapeutic resistance. The observed chemotherapeutic resistance is also described for human NHL and analyses characterizing the human neoplasia revealed specific associated single nucleotide exchanges. Blood samples from patients were collected for routine hematological and biochemical analyses and frozen. DNA will be extracted from each whole blood sample. Mutation screening will be done by conventional quantitative PCR and Next Generation Sequencing Panels using already collected DNA.

Generation of far red and near infrared stably transfected canine cell lines for in vivo tumor detection and compound evaluation
Herstellung von rot- und infrarot-stabil-transfizierten caninen Zelllinien für die in vivo Tumorentdeckung
Project Investigators: I. Nolte; H. Murua Escobar; S. Alnajjar
Duration: Mid 2015 until End 2018
Project Details:
In this project we are going to establish stable transfected cell lines with far-red and near-infrared fluorescent protein. Then fluorescent protein expression analysis will be carried out in vitro and in vivo for evaluation of tumor cell targeting by recombinant CPE in canine mammary cell line derived tumors. The outcome herein will be useful models for in vitro and in vivo monitoring tumor development and evaluation of functionalized CPE binders of canine mammary tumors. Using Relative quantitative one step PCR, the differentiations in claudin gene expression between stably transfected mammary tumor cell lines and non-transfected mammary tumor cell lines will be performed. Genomic screening will be carried out using next generation sequencing for identifying the possible mutation that could be happened as a result for transfection. Fluorescent protein expression analysis will be carried out in vitro and in vivo for evaluation of tumor cell targeting by recombinant CPE in canine mammary cell line derived tumor. In next steps we will transplant continuously different cell lines and cell number in SCDI mice in order to monitor tumor engraftment and development. Further, CPE binders will be applied in vivo to characterize their effect on tumor volume development. Then functionalized CPE binders will be applied in order to evaluate tumor ablation by photonic intervention.

Investigations on measures to optimize feed intake, milk production of the sow and performance of piglets in early life
Untersuchungen zu Optimierungsmöglichkeiten der Futteraufnahme und Milchproduktion der Sau sowie zur Ferkelentwicklung
Project Investigators: Jun. Prof. Dr. C. Visscher; A. Kulüke
Duration: May 2015 until June 2018
Project Details:
In dem Forschungsvorhaben soll näher untersucht werden, inwiefern Maßnahmen wie zootechnische Eingriffe und Impfungen unter den heutigen Bedingungen (große Würfe mit leichten Ferkeln) einen Einfluss auf die Milchaufnahme, die Ferkelentwicklung und damit auch indirekt auf die Leistungsfähigkeit der Sau haben. Die geplanten Untersuchungen werden einerseits unter üblichen Fütterungsbedingungen der Sau, andererseits unter einer ad libitum Fütterung der Sau geprüft. Dies soll gerade deswegen Gegenstand der Untersuchungen sein, weil unter ad libitum Fütterungsbedingungen der Sau am sensibelsten Auswirkungen auf die Futteraufnahme der Sau registriert werden können. In einem weiteren Schritt soll geprüft werden, ob durch Modifikationen in der Proteinversorgung der laktierenden Sau die Milchleistung weiter optimiert werden kann. Mögliche Auswirkungen der in der Saugferkelphase individuell erfassten Parameter (Geburtsgewicht, Entwicklung, etc.) und der in dieser Phase durchgeführten Maßnahmen (Impfung, Fütterung, etc.) sollen weiterführend auf ihre Auswirkungen in der Ferkelaufzucht beobachtet werden.

Bone composition and skeleton health in growing/fattening pigs affected by different phosphorus supply
Entwicklung von Knochenzusammensetzung und Skelettgesundheit wachsender Schweine in Abhängigkeit von der P-Versorgung
Project Investigators: Prof. Dr. J. Kamphues; Prof. Dr. M. Wendt; Dr. C. Schwennen; Dr. C. Ratert; TÄ H. Rieger
Duration: April 2015 until June 2018
Project Details:
In der Aufzucht (Flatdeckphase) und Mast sind prinzipiell drei unterschiedliche Möglichkeiten der P-Versorgung gegeben, nämlich die Verwendung mineralischer P-Verbindungen, die Nutzung des Nicht-Phytin-Phosphors (in pflanzlichen Komponenten eher geringer Anteil) sowie die Verwertung des Phytin-Phosphors dank entsprechender Futterzusatzstoffe (Phytasen). Im ungünstigsten Fall steht den wachsenden Tieren aber nur der Nicht-Phytin aus den pflanzlichen Komponenten zur Verfügung. Vor diesem Hintergrund zielt die Untersuchung auf die Diagnostik einer evtl. marginalen oder gar defizitären P-Versorgung. Insbesondere anhand der Mineralisation unterschiedlicher Knochen im Laufe der Mast soll diese Frage mittels chemischer, physikalischer, klinischer Verfahren (u. a. Röntgen) näher geklärt werden.
