CircRTrain focuses on circular RNAs (circRNAs), a new large class of single-stranded RNAs with covalently closed ends. CircRNAs have only very recently attracted high general interest and become the focus of an increasing number of publications: recent discoveries through sequencing technology and computational analyses have revealed the widespread existence of circRNAs in animal cells. Particularly in neural tissues, circRNA expression is high, dynamic, and evolutionarily conserved. In aging animal brains the expression of certain circRNAs is strongly elevated, suggesting connections to age-related diseases. The study of circRNAs thus emerges as a novel topic with highest importance for the understanding of such diverse conditions as neurodegenerative diseases, aging, and cancer. Moreover, the highly stable expression and their presence in human blood and exosomes make circRNAs attractive biomarker candidates. The overall aims of circRTrain are to 1. Elucidate the biogenesis and function of circRNAs; 2. Define their role in diseases; 3. Exploit their potential as biomarkers and for medical applications; and 4. Combine cutting-edge technologies and disciplines. Understanding circRNAs and exploring their medical relevance requires to integrate various technologies (sequencing, single-molecule and whole-organism imaging, RNA knockdown/delivery, CRISPR/CAS9), disciplines (biochemistry, computational biology, genetics), model systems (worm, fly, mouse, human) and medical applications (biomarkers, new therapeutic strategies). CircRTrain will combine these diverse approaches and industrial technologies by training 15 early stage researchers (ESR) at two SMEs and seven academic partners, which are all leaders in their respective fields. Additionally, cooperation with four partner organizations, circRNA devoted conferences, winter- and summer schools will extend training for the ESRs, sustaining the critical number of young talented professionals in the field.

The consolidation of the knowledge that cancer is not only a genetic, but also a metabolic disease, has led scientists to investigate the intricate metabolic plasticity that transformed cells must undergo to survive the adverse tumor microenvironment conditions, and the contribution of oncogenes and tumor suppressors in shaping metabolism. In this scenario, genetic, biochemical and clinical evidences place mitochondria as key actors in cancer metabolic restructuring, not only because these organelles have a crucial role in the energy and biosynthetic intermediates production but also because occurrence of mutations in metabolic enzymes encoded by both nuclear and mitochondrial DNA has been associated to different types of cancer. TRANSMIT aims to dissect the metabolic remodeling in human cancers, placing the focus on the role of mitochondria and bridging basic research to the improvement/development of therapeutic strategies. Further, TRANSMIT fosters the communication of this emerging field to the patients and their families. To these aims, TRANSMIT will create a network of seven different countries, among which world-leading basic science and clinical centers of excellence, several industrial partners with up-to-date omics technologies, as well as non-profit foundations and associations who care for cancer patients. By creating the critical mass of scientific excellence, TRANSMIT will allow to transfer the current knowledge into the wide field of cancer research, translating scientific and technical advances into the education and training of eleven Early Stage Researchers. TRANSMIT will implement training-through-research dedicated to unravel the metabolic features of cancer, as well as to provide a full portfolio of complementary skills through the creation of a network of basic, translational and industrial laboratories, devoted to a multidisciplinary/multisectorial education of young scientists.

MINOTORs strategic objective is to demonstrate the feasibility of the ECRA technology as a disruptive game-changer in electric propulsion, and to prepare roadmaps paving the way for the 2nd EPIC call, in close alignment with the overall SRC-EPIC strategy. Based on electron cyclotron resonance (ECR) as the sole ionization and acceleration process, ECRA is a cathodeless thruster with magnetic nozzle, allowing thrust vectoring. It has a considerable advantage in terms of global system cost, where a reduction of at least a factor of 2 is expected, and reliability compared to mature technologies. It is also scalable and can potentially be considered for all electric propulsion applications, from microsatellites to space tugs. Although the first results obtained with ECRA have been encouraging, the complexity of the physics at play has been an obstacle for the understanding and development of the technology. Thus an in-depth numerical and experimental investigation plan has been devised for the project, in order to bring the technology from TRL3 to TRL5. The strong consortium is composed of academic experts to perform the research activities on ECRA, including alternative propellants, along with experienced industrial partners to quantify its disruptive advantages on the propulsion subsystem and its market positioning. ECRAs advantages as an electric thruster technology can be a disruptive force in a mostly cost-driven satellite market. It would increase European competitiveness, help develop low-cost satellite missions such as constellations, provide end-of-life propulsion, and pave the way for future emerging electric propulsion technologies. The 36 months MINOTOR project requests a total EC grant of 1 485 809 M for an experienced consortium of 7 partners from 4 countries: ONERA (FR, Coordinator), industries Thales Alenia Space (BE), Thales Microelectronics (FR), SNECMA (FR), Universities Carlos III (ES) and Giessen (GE), and SME L-up (FR).

Probability of event-free survival (pEFS) in pediatric T-cell lymphoblastic lymphoma is about 80%, whereas survival in relapsed patients is very poor. No stratification criteria have been established so far. Recently, activating NOTCH1 mutations were reported to be associated with favorable prognosis, and loss of heterozygosity at chromosome 6q (LOH6q) was reported to be associated with increased relapse risk. The current project was intended to evaluate the prognostic effect of these markers. Mutations in hot spots of NOTCH1 and FBXW7 were analyzed in 116 patients. Concerning LOH6q status, 118 patients were investigated, using microsatellite marker analysis, in addition to an earlier reported cohort of 99 available patients. Ninety-two cases were evaluable for both analyses. All patients were treated with T-cell lymphoblastic lymphoma-Berlin-Frankfurt-Münster group (BFM)-type treatment. LOH6q was observed in 12% of patients (25/217) and associated with unfavorable prognosis (pEFS 27% ± 9% vs 86% ± 3%; P < .0001). In 60% (70/116) of the patients, NOTCH1 mutations were detected and associated with favorable prognosis (pEFS 84% ± 5% vs 66% ± 7%; P = .021). Interestingly, NOTCH1 mutations were rarely observed in patients with LOH in 6q16. Both prognostic markers will be used as stratification criteria in coming Non-Hodgkin Lymphoma-BFM trials.

The formation of semiconductor composites comprising multicomponent or multiphase heterojunctions is a very effective strategy to design highly active photocatalyst systems. This review summarizes the recent strategies to develop such composites, and highlights the most recent developments in the field. After a general introduction into the different strategies to improve photocatalytic activity through formation of heterojunctions, the three different types of heterojunctions are introduced in detail, followed by a historical introduction to semiconductor heterojunction systems and a thorough literature overview. Special chapters describe the highly-investigated carbon nitride heterojunctions as well as very recent developments in terms of multiphase heterojunction formation, including the latest insights into the anatase-rutile system. When carefully designed, semiconductor composites comprising two or three different materials or phases very effectively facilitate charge separation and charge carrier transfer, substantially improving photocatalytic and photoelectrochemical efficiency. The formation of semiconductor composites, leading to multicomponent and multiphase heterojunctions, is herein reviewed. Highly active photocatalyst systems with improved charge carrier separation and charge transfer are the result, leading to significantly enhanced efficiencies. Particular interest is given to recent developments in multiphase composites © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Extensive studies in both lower and higher plants indicate that plant phytochrome photoreceptors signal not only by regulating transcription in the nucleus but also by acting within the cytoplasm, the latter signaling routes acting within minutes or even seconds and also providing directional information. Directional signals seem to arise from phytochromes attached anisotropically to the plasma membrane. Neochromes-phytochrome-phototropin hybrid photoreceptors probably attached to the plasma membrane-provide this signal in various ferns and perhaps certain algae but are absent from other groups. In mosses and probably higher plants too, a subpopulation of canonical phytochromes interact with phototropins at the plasma membrane and thereby steer directional responses. Phytochromes also seem able to regulate translation in the cytoplasm. This review discusses putative phytochrome functions in these contexts. © Copyright ©2013 by Annual Reviews.
