  abstract  = {Since the advent of high-throughput sequencing technologies in the mid-2010s, RNA se- quencing (RNA-seq) has been established as the method of choice for studying gene expression. In comparison to microarray-based methods, which have mainly been used to study gene expression before the rise of RNA-seq, RNA-seq is able to profile the entire transcriptome of an organism without the need to predefine genes of interest. Today, a wide variety of RNA-seq methods and protocols exist, including dual RNA sequenc- ing (dual RNA-seq) and multi RNA sequencing (multi RNA-seq). Dual RNA-seq and multi RNA-seq simultaneously investigate the transcriptomes of two or more species, re- spectively. Therefore, the total RNA of all interacting species is sequenced together and only separated in silico. Compared to conventional RNA-seq, which can only investi- gate one species at a time, dual RNA-seq and multi RNA-seq analyses can connect the transcriptome changes of the species being investigated and thus give a clearer picture of the interspecies interactions. Dual RNA-seq and multi RNA-seq have been applied to a variety of host-pathogen, mutualistic and commensal interaction systems. We applied dual RNA-seq to a host-pathogen system of human mast cells and Staphylo- coccus aureus (S. aureus). S. aureus, a commensal gram-positive bacterium, can become an opportunistic pathogen and infect skin lesions of atopic dermatitis (AD) patients. Among the first immune cells S. aureus encounters are mast cells, which have previously been shown to be able to kill the bacteria by discharging antimicrobial products and re- leasing extracellular traps made of protein and deoxyribonucleic acid (DNA). However, S. aureus is known to evade the host's immune response by internalizing within mast cells. Our dual RNA-seq analysis of different infection settings revealed that mast cells and S. aureus need physical contact to influence each other's gene expression. We could show that S. aureus cells internalizing within mast cells undergo profound transcriptome changes to adjust their metabolism to survive in the intracellular niche. On the host side, we found out that infected mast cells elicit a type-I interferon (IFN-I) response in an autocrine manner and in a paracrine manner to non-infected bystander-cells. Our study provides the first evidence that mast cells are capable to produce IFN-I upon infection with a bacterial pathogen.},

  abstract  = {To foster sustainable environmentally friendly behavior in children it is important to provide an effective form of environmental education. In this context we studied three important factors: Attitude towards nature, environmental knowledge and advanced expert knowledge. Concerning attitude towards nature our first question was: "Is it possible to affect primary school children's environmental values during a one-day visit at a wildlife park?" As a control, the program was also conducted in schools, leading to two different learning settings- wildlife park and school. Regarding environmental knowledge, in our second question we wanted to know, if our modified teaching approach "guided learning at workstations" (G) combining instructional and constructivist elements would lead to good cognitive learning results of primary school children. Additionally, we compared it to a stronger teacher-centered (T) as well as to a stronger student-centered (S) approach. The third question we asked was "Is it possible to convey fascinating expert knowledge on a more advanced subject to primary school children using conceptual change theory?" After gathering primary school children's preconceptions, we defined different groups due to the heterogeneity of their pre-existing conceptions and the change in conceptions. Based on this research we designed a program along with an instrument to measure the impact of the conceptual change teaching method. After years of building a strong cooperation between the section Didactics of Biology at the Julius-Maximilians University W{\"u}rzburg, the nearby schools and the wildlife park "Wild-Park Klaushof" near Bad Kissingen in northern Bavaria it was time to evaluate the environmental education programs prepared and applied by undergraduate university students. As a model species we chose the European wildcat (Felis silvestris silvestris) which represents endangered wildlife in Europe and the need for human interaction for the sake of preserving a species by restoring or recreating the habitat conditions needed while maintaining current infrastructure. Drawing from our own as well as teachers' and university students' experiences, we built, implemented and evaluated a hands-on program following several workstations between the wildcat enclosure and the wildlife park's green classroom. The content of our intervention was presented as a problem-oriented lesson, where children were confronted with the need for human interaction in order to preserve the European wildcat. Not only on a theoretical basis, but very specific to their hometowns they were told where and when nature conservation groups met or where to donate money. 692 Bavarian third grade primary school children in 35 classes participated in the one-day intervention that took place between the months of april, 2014 and november, 2015 in the wildlife park or in their respective classrooms. The ages varied between 8 and 11 years with the mean age being 8.88 ± 0.56 years old. 48.6 \% of them were boys, 51.4 \% were girls. (1) To measure primary school children's environmental attitudes a questionnaire on two major environmental values- preservation and utilization of nature- was administered in a pre, post- and retention test design. It was possible to affect primary school children's environmental preservation values during our one-day program. This result could be found not only at the wildlife park but unexpectedly also in school, where we educated classes for control purposes. We also found this impact consistent in all used teaching approaches and were surprised to see the preservation values change in a way we did not expect from higher tendency towards preservation of nature to a lower one. We presume that children of this age group reflected on the contents of our intervention. This had an influence on their own values towards preservation which led to a more realistic marking behavior in the questionnaire. We therefore conclude that it is possible to affect primary school children's environmental values with a one-day program on environmental content. (2) We were interested in conveying environmental knowledge about the European wildcat; its morphology, ecology and behavior. We designed and applied a knowledge questionnaire also in a pre-, post- and retention test design, to find out, whether different forms of instruction made a difference in learning success of primary school children. We used two approaches with a teacher in the role of a didactic leader- our modified guided approach (G) as well as a stronger teacher-centered one (T) with a higher focus on instruction. The third approach was presented as a strong student-centered learning at workstations (S) without a didactic leader we also called "free learning at workstations". Overall, all children's knowledge scores changed significantly from pre- to post-test and from pre- to retention test, indicating learning success. Differences could only be found between the posttest values of both approaches with a didactic leader (G, T) in comparison to the strong student-centered (S) form. It appears that these primary school children gained knowledge at the out of school learning setting regardless of the used teaching approach. On the subject of short-term differences, we discuss, that the difference in learning success might have been consistent from post to retention test if a consolidation phase had been added in the days following the program as should be common practice after a visit to an out-of- school learning setting but was not part of our intervention. When comparing both approaches with a didactic leader (G, T), we prefer our modified guided learning at workstations (G) since constructivist phases can be implemented without losses concerning learning success. Moreover, the (at least temporary) presence of a teacher in the role of a didactic leader ensures maintained discipline and counteracts off-task behavior. To make sure, different emotional states did not factor in our program, we measured children's situational emotions directly after the morning intervention using a short scale that evaluated interest, wellbeing and boredom. We found, that these emotions remained consistent over both learning settings as well as different forms of instruction. While interest and wellbeing remained constantly high, boredom values remained low. We take this as a sign of high quality designing and conducting the intervention. (3) In the afternoon of the one-day intervention, children were given the opportunity to investigate the wildcat further, this time using the conceptual change theory in combination with a more complex and fascinating content: cats' vision in dusk and dawn. Children were confronted with their preconceptions which had been sampled prior to the study and turned into three distinctive topics reflected in a special questionnaire. In a pre-, post and retention test design we included the most common alternative conceptions, the scientifically correct conceptions as well as other preconceptions. We gathered a high heterogeneity of preconceptions and defined three groups based on conceptual change literature: "Conceptual change", "Synthetic Models" and "Conceptual Growth". In addition to these we identified two more groups after our data analysis: "Knowledge" and "Non-addressed Concepts". We found that instruction according to the conceptual change theory did not work with primary school children in our intervention. The conceptual change from the addressed alternative conceptions as well as from other preconceptions towards the scientifically correct conceptions was successfully achieved only on occasion. In our case and depending on the topic only one third to one fourth of the children actually held the addressed conception while the rest was not targeted by the instruction. Moreover, we conclude children holding other conceptions were rather confused than educated by the confrontation. We assume that children of this age group may be overchallenged by the conceptual change method.},

  abstract  = {N-MYC is a member of the human MYC proto-oncogene family, which comprises three transcription factors (C-, N- and L-MYC) that function in multiple biological processes. Deregulated expression of MYC proteins is linked to tumour initiation, maintenance and progression. For example, a large fraction of neuroblastoma displays high N-MYC levels due to an amplification of the N-MYC encoding gene. MYCN-amplified neuroblastoma depend on high N-MYC protein levels, which are maintained by Aurora-A kinase. Aurora-A interaction with N-MYC interferes with degradation of N-MYC via the E3 ubiquitin ligase SCFFBXW7. However, the underlying mechanism of Aurora-A-mediated stabilisation of N-MYC remains to be elucidated. To identify novel N-MYC interacting proteins, which could be involved in N-MYC stabilisation by Aurora-A, a proteomic analysis of purified N-MYC protein complexes was conducted. Since two alanine mutations in MBI of N-MYC, T58A and S62A (N-MYC mut), disable Aurora-A-mediated stabilisation of N-MYC, N-MYC protein complexes from cells expressing either N-MYC wt or mut were analysed. Proteomic analysis revealed that N-MYC interacts with two deubiquitinating enzymes, USP7 and USP11, which catalyse the removal of ubiquitin chains from target proteins, preventing recognition by the proteasome and subsequent degradation. Although N-MYC interaction with USP7 and USP11 was confirmed in subsequent immunoprecipitation experiments, neither USP7, nor USP11 was shown to be involved in the regulation of N-MYC stability. Besides USP7/11, proteomic analyses identified numerous additional N-MYC interacting proteins that were not described to interact with MYC transcription factors previously. Interestingly, many of the identified N-MYC interaction partners displayed a preference for the interaction with N-MYC wt, suggesting a MBI-dependent interaction. Among these were several proteins, which are involved in three-dimensional organisation of chromatin domains and transcriptional elongation by POL II. Not only the interaction of N-MYC with proteins functioning in elongation, such as the DSIF component SPT5 and the PAF1C components CDC73 and CTR9, was validated in immunoprecipitation experiments, but also with the POL III transcription factor TFIIIC and topoisomerases TOP2A/B. ChIP-sequencing analysis of N-MYC and TFIIIC subunit 5 (TFIIIC5) revealed a large number of joint binding sites in POL II promoters and intergenic regions, which are characterised by the presence of a specific motif that is highly similar to the CTCF motif. Additionally, N-MYC was shown to interact with the ring-shaped cohesin complex that is known to bind to CTCF motifs and to assist the insulator protein CTCF. Importantly, individual ChIP experiments demonstrated that N-MYC, TFIIIC5 and cohesin subunit RAD21 occupy joint binding sites comprising a CTCF motif. Collectively, the results indicate that N-MYC functions in two biological processes that have not been linked to MYC biology previously. Furthermore, the identification of joint binding sites of N-MYC, TFIIIC and cohesin and the confirmation of their interaction with each other suggests a novel function of MYC transcription factors in three-dimensional organisation of chromatin.},

  abstract  = {Blood is a remarkable habitat: it is highly viscous, contains a dense packaging of cells and perpetually flows at velocities varying over three orders of magnitude. Only few pathogens endure the harsh physical conditions within the vertebrate bloodstream and prosper despite being constantly attacked by host antibodies. African trypanosomes are strictly extracellular blood parasites, which evade the immune response through a system of antigenic variation and incessant motility. How the flagellates actually swim in blood remains to be elucidated. Here, we show that the mode and dynamics of trypanosome locomotion are a trait of life within a crowded environment. Using high-speed fluorescence microscopy and ordered micro-pillar arrays we show that the parasites mode of motility is adapted to the density of cells in blood. Trypanosomes are pulled forward by the planar beat of the single flagellum. Hydrodynamic flow across the asymmetrically shaped cell body translates into its rotational movement. Importantly, the presence of particles with the shape, size and spacing of blood cells is required and sufficient for trypanosomes to reach maximum forward velocity. If the density of obstacles, however, is further increased to resemble collagen networks or tissue spaces, the parasites reverse their flagellar beat and consequently swim backwards, in this way avoiding getting trapped. In the absence of obstacles, this flagellar beat reversal occurs randomly resulting in irregular waveforms and apparent cell tumbling. Thus, the swimming behavior of trypanosomes is a surprising example of micro-adaptation to life at low Reynolds numbers. For a precise physical interpretation, we compare our high-resolution microscopic data to results from a simulation technique that combines the method of multi-particle collision dynamics with a triangulated surface model. The simulation produces a rotating cell body and a helical swimming path, providing a functioning simulation method for a microorganism with a complex swimming strategy},

  abstract  = {Ofall amphibians living in arid habitats, reed frogs (belonging to the super species Hyperolius viridiflavus) are the most peculiar. Froglets are able to tolerate dry periods of up to 35 days or longer immediately after metamorphosis, in climatically exposed positions. They face similar problems to estivating juveniles, i.e. enduranee of long periods of high temperature and low RH with rather limited energy and water reserves. In addition, they must have had to develop meehanisms to prevent poisoning by nitrogenous wastes that rapidly accumulate during dry periods as a metabolie consequenee of maintaining a non-torpid state. During dry periods, plasma osmolarity of H. v. taeniatus froglets strongly increased, mainly through urea accumulation. Urea accumulation was also observed during metamorphic climax. During postmetamorphic growth, chromatophores develop with the density and morphology typical of the adult pigmentary pattern. The dermal iridophore layer, which is still incomplete at this time, is fully developed within 4-8 days after metamorphosis, irrespective of maintenance conditions. These iridophores mainly contain the purines guanine and hypoxanthine. The ability of these purines to reflect light provides an excellent basis for the role of iridophores in temperature regulation. In individuals experiencing dehydration stress, the initial rate of purine synthesis is doubled in eomparison to specimens continuously maintained under wet season conditions. This increase in synthesis rate leads to a rapid increase in the thiekness of the iridophore layer, thereby effectively reducing radiation absorption. Thus, the danger of overheating is diminished during periods of water shortage when evaporative cooling must be avoided. After the development of an iridophore layer of sufficient thickness for effective radiation reflectance, synthesis of iridophore pigments does not cease. Rather, this pathway is further used during the remaining dry season for solving osmotic problems eaused by accumulation of nitrogenous wastes. During prolonged water deprivation, in spite of reduced metabolic rates, purine pigments are produced at the same rate as in wet season conditions. This leads to a higher relative proportion of nitrogen end products being stored in skin pigments under dry season conditions. At the end of an experimental dry season lasting 35 days, up to 38\% of the accrued nitrogen is stored in the form of osmotically inactive purines in thc skin. Thus the osmotic problems caused by evaporative water loss and urea production are greatly reduced.},

  abstract  = {Reed frogs of the superspecies Hyperolius viridiflavus occur throughout the seasonally very dry and hot African savannas. Despite their small size (300-700 mg), estivating reed frogs do not avoid stressful conditions above ground by burrowing into the soil, but endure the inhospitable climate relatively unprotected, clinging to mostly dry grass sterns. They must have emcient mechanisms to enable them to survive e.g. very high temperatures, low relative hurnidities, and high solar radiation loads. Mechanisms must also have developed to prevent poisoning by the nitrogenous wastes that inevitably result from protein and nucleotide turnover. In contrast to fossorial amphibians, estivating reed frogs do not become torpid. Reduction in metabolism is therefore rather Iimited so that nitrogenous wastes accumulate faster in these frogs than in fossorial amphibians. This severely aggravates the osmotic problems caused by dehydration. During dry periods total plasma osmolarity greatly increases, mainly due to urea accumulation. Of the total urea accumulated over 42 days of experimental water deprivation, 30\% was produced during the first 7 days. In the next 7 days rise in plasma urea content was negligible. This strong initial increase of urea is seen as a byproduct of elevated amino acid catabolism following the onset of dry conditions. Tbe rise in total plasma osmolarity due to urea accumulation, however, is not totally disadvantageous, but enables fast rehydration when water is available for very short periods only. Voiding of urine and feces eeases once evaporative water loss exceeds 10\% of body weight. Tberefore, during continuous water deprivation, nitrogenous end products are not excreted. After 42 days of water deprivation, bladder fluid was substantially depleted, and urea coneentration in the remaining urine (up to 447 mM) was never greater than in plasma fluid. Feces voided at the end of the dry period after water uptake contained only small amounts of nitrogenous end products. DSF (dry season frogs) seemed not to be uricotelic. Instead, up to 35\% of the total nitrogenous wastes produced over 42 days of water deprivation were deposited in an osmotically inert and nontoxic form in iridophore crystals. The increase in skin purine content averaged 150 µg/mg dry weight. If urea had been the only nitrogenous waste product during an estivation period of 42 days, lethal limits of total osmolarity (about 700 mOsm) would have been reached 10-14 days earlier. Thus iridophores are not only involved in colour change and in reducing heat load by radiation remission, but are also important in osmoregulation during dry periods. The seIective advantages of deposition of guanine rather than uric acid are discussed.},

  abstract  = {Scorpions, living in North African semideserts are - in spite of disrupting experimental interferences - able to maintain a certain direction in their natural environment in the dark on a plane surface. Under comparable laboratory conditions, excluding the possibility of light or gravity orientation, they can orient themselves if a directed air current passes over the "arena." In most cases the scorpions do not run necessarily with or against the wind, but rather maintain constant angles to the air current for anywhere from minutes to many hours. They are running anemomenotactically (ref. 1). Under identical conditions many species of beetles also orient themselves to air currents (refs. 2 to 4). The main problems to be solved in the study of anemomenotactic orientation are: (1) Which physical qualities of the air current have an influence on the anemomenotaxis? (2) With which sense organs do beetles and scorpions perceive wind directions? (3) Which physiological mechanism is the basis of anemomenotactic orientation? (4) What is the biological significance of anemomenotaxis in beetles and scorpions? With respect to these problems, more study has been done on beetles than on scorpions. Therefore, due to lack of space, I shall discuss mainly some of the results obtained in experiments with dung beetles (Geotrupes silvaticus, G. ,Stercorarius, G. armifrons, G. niger, Scarabaeus variolosus) and tenebrionid beetles (Tenebrio molitor, Pimelia grossa, P. tenuicomis, Scaurus dubius).},

It is predicted that higher temperatures will lead to advanced snowmelt dates and that the number of extreme weather events will increase. The aims of this study were to determine the impacts of extreme climatic events on flower phenology and to assess whether those impacts differed between lower and higher altitudes. In 2010 an experiment simulating advanced and delayed snowmelt as well as drought event was conducted along an altitudinal transect ca. every 250m (600-2000 m a.s.l.) in the Berchtesgaden National Park, Germany. The study showed that flower phenology is strongly affected by altitude; however there were few effects of the manipulative treatments on flowering. The effects of advanced snowmelt were significantly greater at higher than at lower sites, but no significant difference was found between both altitudinal bands for the other treatments. The response of flower phenology to temperature declined through the season and the length of flowering duration was not significantly influenced by treatments. The stronger effect of advanced snowmelt at higher altitudes might be a response to differences in treatment intensity across the gradient. Consequently, shifts in the date of snowmelt due to global warming may affect species more at higher than at lower altitudes since changes may be more pronounced at higher altitudes. Our data indicate a rather low risk of drought events on flowering phenology in the Bavarian Alps.},

  abstract  = {Background: Measles virus (MV) causes T cell suppression by interference with phosphatidylinositol-3-kinase (PI3K) activation. We previously found that this interference affected the activity of splice regulatory proteins and a T cell inhibitory protein isoform was produced from an alternatively spliced pre-mRNA. Hypothesis: Differentially regulated and alternatively splice variant transcripts accumulating in response to PI3K abrogation in T cells potentially encode proteins involved in T cell silencing. Methods: To test this hypothesis at the cellular level, we performed a Human Exon 1.0 ST Array on RNAs isolated from T cells stimulated only or stimulated after PI3K inhibition. We developed a simple algorithm based on a splicing index to detect genes that undergo alternative splicing (AS) or are differentially regulated (RG) upon T cell suppression. Results: Applying our algorithm to the data, 9\% of the genes were assigned as AS, while only 3\% were attributed to RG. Though there are overlaps, AS and RG genes differed with regard to functional regulation, and were found to be enriched in different functional groups. AS genes targeted extracellular matrix (ECM)-receptor interaction and focal adhesion pathways, while RG genes were mainly enriched in cytokine-receptor interaction and Jak-STAT. When combined, AS/RG dependent alterations targeted pathways essential for T cell receptor signaling, cytoskeletal dynamics and cell cycle entry. Conclusions: PI3K abrogation interferes with key T cell activation processes through both differential expression and alternative splicing, which together actively contribute to T cell suppression.},
