Utrecht University is a university in Utrecht, the Netherlands. It is one of the oldest universities in the Netherlands and one of the largest in Europe. Established March 26, 1636, it had an enrollment of 30,449 students in 2012, and employed 5,295 faculty and staff. In 2011, 485 PhD degrees were awarded and 7,773 scientific articles were published. The 2013 budget of the university was €765 million.The university is rated as the best university in the Netherlands by the Shanghai Ranking of World Universities 2013, and ranked as the 13th best European university and the 52nd best university of the world.The university's motto is "Sol Iustitiae Illustra Nos," which means "Sun of Justice, shine upon us." This motto was gleaned from a literal Latin Bible translation of Malachi 4:2. Utrecht University is led by the University Board, consisting of prof. dr. Bert van der Zwaan and Hans Amman.

The invention concerns derivatives of CMAP27, which have a good antimicrobial activity and a low haemolytic activity as compared to the wild-type CMAP27 peptide. These derivatives can be used for antibiotic therapy or in a bacteriocidal composition. Further comprised in the invention is the use of CMAP27 and/or its derivatives as adjuvant.

The present invention provides new derivatives of CATH2 or CMAP27, one of the cathelicidins. These derivatives comprise N-terminally truncated peptides, cyclic peptides, D-amino acid variants of CATH2 and its truncated derivatives, inverso and retro-inverso CATH2 derivatives. These derivatives are useful as anti-infectives, in vaccines, and especially for in ovo applications. Further, for the above derivatives and also for the already known C-terminally truncated derivatives new immunoactivating functions have been described that are particularly advantageous for prophylactic treatments.

The WNT signal transduction cascade controls myriad biological phenomena throughout development and adult life of all animals. In parallel, aberrant Wnt signaling underlies a wide range of pathologies in humans. In this Review, we provide an update of the core Wnt/β-catenin signaling pathway, discuss how its various components contribute to disease, and pose outstanding questions to be addressed in the future. © 2012 Elsevier Inc. © 2012 Elsevier Inc.

Colloidal heteronanocrystals (HNCs) can be regarded as solution-grown inorganic-organic hybrid nanomaterials, since they consist of inorganic nanoparticles that are coated with a layer of organic ligand molecules. The hybrid nature of these nanostructures provides great flexibility in engineering their physical and chemical properties. The inorganic particles are heterostructured, i.e. they comprise two (or more) different materials joined together, what gives them remarkable and unique properties that can be controlled by the composition, size and shape of each component of the HNC. The interaction between the inorganic component and the organic ligand molecules allows the size and shape of the HNCs to be controlled and gives rise to novel properties. Moreover, the organic surfactant layer opens up the possibility of surface chemistry manipulation, making it possible to tailor a number of properties. These features have turned colloidal HNCs into promising materials for a number of applications, spurring a growing interest on the investigation of their preparation and properties. This critical review provides an overview of recent developments in this rapidly expanding field, with emphasis on semiconductor HNCs (e.g., quantum dots and quantum rods). In addition to defining the state of the art and highlighting the key issues in the field, this review addresses the fundamental physical and chemical principles needed to understand the properties and preparation of colloidal HNCs (283 references). © 2011 The Royal Society of Chemistry.


Signaling between endothelial cells, endothelial progenitor cells, and stromal cells is crucial for the establishment and maintenance of vascular integrity and involves exosomes, among other signaling pathways. Exosomes are important mediators of intercellular communication in immune signaling, tumor survival, stress responses, and angiogenesis. The ability of exosomes to incorporate and transfer messenger RNAs (mRNAs) encoding for "acquired" proteins or micro RNAs (miRNAs) repressing "resident" mRNA translation suggests that they can influence the physiological behavior of recipient cells. We demonstrate that miR-214, an miRNA that controls endothelial cell function and angiogenesis, plays a dominant role in exosome-mediated signaling between endothelial cells. Endothelial cell-derived exosomes stimulated migration and angiogenesis in recipient cells, whereas exosomes from miR-214-depleted endothelial cells failed to stimulate these processes. Exosomes containing miR-214 repressed the expression of ataxia telangiectasia mutated in recipient cells, thereby preventing senescence and allowing blood vessel formation. Concordantly, specific reduction of miR-214 content in exosome-producing endothelial cells abolishes the angiogenesis stimulatory function of the resulting exosomes. Collectively, our data indicate that endothelial cells release miR-214-containing exosomes to stimulate angiogenesis through the silencing of ataxia telangiectasia mutated in neighboring target cells.

In the past decade, microRNAs (miRNAs) have been uncovered as key regulators of gene expression at the post-transcriptional level. The ancient origin of miRNAs, their dramatic expansion in bilaterian animals and their function in providing robustness to transcriptional programmes suggest that miRNAs are instrumental in the evolution of organismal complexity. Advances in understanding miRNA biology, combined with the increasing availability of diverse sequenced genomes, have begun to reveal the molecular mechanisms that underlie the evolution of miRNAs and their targets. Insights are also emerging into how the evolution of miRNA-containing regulatory networks has contributed to organismal complexity. © 2011 Macmillan Publishers Limited. All rights reserved.

Over the last decade, the notion that tumors are maintained by their own stem cells, the so-called cancer stem cells, has created great excitement in the research community. This review attempts to summarize the underlying concepts of this notion, to distinguish hard facts from beliefs and to define the future challenges of the field. © 2011 Nature America, Inc.

Small non-coding RNAs, through association with Argonaute protein family members, have a variety of functions during the development of an organism. Although there is increased mechanistic understanding of the RNA interference (RNAi) pathways surrounding these small RNAs, how their effects are modulated by subcellular compartmentalization and cross-pathway functional interactions is only beginning to be explored. This review examines the current understanding of these aspects of RNAi pathways and the biological functions of these pathways. © 2011 Elsevier Inc.
