  abstract  = {Motoneurons played an essential role in establishing the concept of target-mediated support of innervating neurons. However, it took several decades until molecules were identined which trophically support motoneurons in vitro and in vivo. The most potent molecule identined so far is ciliary neurotrophic factor (CNTF). It is expressed as a cytosolic molecule in myelinating Schwann cells rather than in skeletal muscle in the postnatal period and therefore does not qualify as a target-derived neurotrophic factor regulating motoneuron survival during embryonic development. However, the inactivation of CNTF by gene targeting experiments results in progressive atrophy and degeneration of motoneurons, demonstrating that CNTF plays an essential role as a maintenance factor for motoneurons postnatally. Secretory molecules which are expressed in skeletal muscle during embryonic development and which support motoneurons in culture and partially also in vivo include members of the NGF gene family (BDNF, NT-3, NT-4/S) , FGF-S, IGF-I, and UF. The evaluation of the physiological importance of these molecules is under investigation.},

  abstract  = {The DREAM complex plays an important role in regulation of gene expression during the cell cycle. We have previously shown that the DREAM subunit LIN9 is required for early embryonic development and for the maintenance of the inner cell mass in vitro. In this study we examined the effect of knocking down LIN9 on ESCs. We demonstrate that depletion of LIN9 alters the cell cycle distribution of ESCs and results in an accumulation of cells in G2 and M and in an increase of polyploid cells. Genome-wide expression studies showed that the depletion of LIN9 results in downregulation of mitotic genes and in upregulation of differentiation-specific genes. ChIP-on chip experiments showed that mitotic genes are direct targets of LIN9 while lineage specific markers are regulated indirectly. Importantly, depletion of LIN9 does not alter the expression of pluripotency markers SOX2, OCT4 and Nanog and LIN9 depleted ESCs retain alkaline phosphatase activity. We conclude that LIN9 is essential for proliferation and genome stability of ESCs by activating genes with important functions in mitosis and cytokinesis.},

  abstract  = {Background The identification of additional prognostic markers to improve risk stratification and to avoid overtreatment is one of the most urgent clinical needs in prostate cancer (PCa). MicroRNAs, being important regulators of gene expression, are promising biomarkers in various cancer entities, though the impact as prognostic predictors in PCa is poorly understood. The aim of this study was to identify specific miRNAs as potential prognostic markers in high-risk PCa and to validate their clinical impact. Methodology and Principal Findings We performed miRNA-microarray analysis in a high-risk PCa study group selected by their clinical outcome (clinical progression free survival (CPFS) vs. clinical failure (CF)). We identified seven candidate miRNAs (let-7a/b/c, miR-515-3p/5p, -181b, -146b, and -361) that showed differential expression between both groups. Further qRT-PCR analysis revealed down-regulation of members of the let-7 family in the majority of a large, well-characterized high-risk PCa cohort (n = 98). Expression of let-7a/b/and -c was correlated to clinical outcome parameters of this group. While let-7a showed no association or correlation with clinical relevant data, let-7b and let-7c were associated with CF in PCa patients and functioned partially as independent prognostic marker. Validation of the data using an independent high-risk study cohort revealed that let-7b, but not let-7c, has impact as an independent prognostic marker for BCR and CF. Furthermore, we identified HMGA1, a non-histone protein, as a new target of let-7b and found correlation of let-7b down-regulation with HMGA1 over-expression in primary PCa samples. Conclusion Our findings define a distinct miRNA expression profile in PCa cases with early CF and identified let-7b as prognostic biomarker in high-risk PCa. This study highlights the importance of let-7b as tumor suppressor miRNA in high-risk PCa and presents a basis to improve individual therapy for high-risk PCa patients.},

  abstract  = {Gegenstand dieser Arbeit ist die Erstellung eines sogenannten "Targeting Vektors" zur gezielten Ausschaltung des Gens f{\"u}r Plasmakallikrein in der Maus, als Vorbereitung zur Schaffung einer Plasmakallikrein-defizienten Mauslinie. Plasmakallikrein ist eine im Blut zirkulierende Serinprotease, die Funktionen in H{\"a}mostase, Thrombusbildung und Fibrinolyse hat sowie sowohl direkt als auch indirekt mittels Bradykinin an Entz{\"u}ndungsvorg{\"a}ngen beteiligt ist. Zwei 5836 und 3834 bp lange Abschnitte aus dem murinen Plasmakallikrein-Gen wurden durch PCR isoliert und in ein Plasmid kloniert, das neben Resistenzgenen gegen Ampicillin und Neomycin auch das β-Galaktosidase-Gen zum Nachweis einer erfolgreichen Transfektion enth{\"a}lt. Der so entstandene "Targeting Vektor" hat eine Gesamtgr{\"o}ße von 18072 bp, die Basensequenz wurde durch Sequenzierung verifiziert. Der Vektor soll im Plasmakallikrein-Gen einen Teil der Exons 2 und 3 und damit einen Großteil des Signalpeptids und der ersten Proteindom{\"a}ne funktionsunf{\"a}hig machen. An den mit dieser Methode erstellten Knockout-M{\"a}usen k{\"o}nnen die Funktionen von Plasmakallikrein genauer untersucht werden.},
