Here, we unravel interaction of structural, mutational, and transcriptional changes, which contribute to MYC oncogene dysregulation together with the pathognomonic IG-MYC translocation. Moreover, by mapping IGH translocation breakpoints, we provide evidence that the precursor of at least a subset of BL is a B-cell poised to express IGHA. We describe the landscape of mutations, structural variants, and mutational processes, and identified a series of driver genes in the pathogenesis of BL, which can be targeted by various mechanisms, including IG-non MYC translocations, germline and somatic mutations, fusion transcripts, and alternative splicing.}, language = {en} } @article{MitchellLiWeinholdetal.2016, author = {Mitchell, Jonathan S. and Li, Ni and Weinhold, Niels and F{\"o}rsti, Asta and Ali, Mina and van Duin, Mark and Thorleifsson, Gudmar and Johnson, David C. and Chen, Bowang and Halvarsson, Britt-Marie and Gudbjartsson, Daniel F. and Kuiper, Rowan and Stephens, Owen W. and Bertsch, Uta and Broderick, Peter and Campo, Chiara and Einsele, Hermann and Gregory, Walter A. and Gullberg, Urban and Henrion, Marc and Hillengass, Jens and Hoffmann, Per and Jackson, Graham H. and Johnsson, Ellinor and J{\"o}ud, Magnus and Kristinsson, Sigurdur Y. and Lenhoff, Stig and Lenive, Oleg and Mellqvist, Ulf-Henrik and Migliorini, Gabriele and Nahi, Hareth and Nelander, Sven and Nickel, Jolanta and N{\"o}then, Markus M. and Rafnar, Thorunn and Ross, Fiona M. and da Silva Filho, Miguel Inacio and Swaminathan, Bhairavi and Thomsen, Hauke and Turesson, Ingemar and Vangsted, Annette and Vogel, Ulla and Waage, Anders and Walker, Brian A. and Wihlborg, Anna-Karin and Broyl, Annemiek and Davies, Faith E. and Thorsteinsdottir, Unnur and Langer, Christian and Hansson, Markus and Kaiser, Martin and Sonneveld, Pieter and Stefansson, Kari and Morgan, Gareth J. and Goldschmidt, Hartmut and Hemminki, Kari and Nilsson, Bj{\"o}rn and Houlston, Richard S.}, title = {Genome-wide association study identifies multiple susceptibility loci for multiple myeloma}, series = {Nature Communications}, volume = {7}, journal = {Nature Communications}, doi = {10.1038/ncomms12050}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-165983}, pages = {12050}, year = {2016}, abstract = {Multiple myeloma (MM) is a plasma cell malignancy with a significant heritable basis.

Es kann dann von einem molekularen Schalter gesprochen werden. Im Rahmen dieser Arbeit wurde eine vom cyclischen Peptidantibiotikum Gramicidin S abgeleitete 18mer-Peptid-Alanyl-PNA-Chim{\"a}re 20 mit eingebautem Alanyl-PNA-Pentamer dargestellt. Es konnte mittels temperaturabh{\"a}ngiger UV-Spektroskopie gezeigt werden, dass sich bei Zugabe des komplement{\"a}ren Gegenstranges nichtkovalente Duplexe bilden. CD-spektroskopische Untersuchungen dieses Dimers lieferten keine eindeutigen Beweise f{\"u}r das vorliegen eines \&\#946;-Faltblattes. Es konnte anhand des humanen Interleukins 8 gezeigt werden, dass der Einbau von Alanyl-PNA durch die Technik der native chemical ligation in gr{\"o}ßere Peptide m{\"o}glich ist. Hierf{\"u}r wurde der N-terminale Thioester 31 des humanen Interleukins hIL8(1-55) durch Expression des Fusionsproteines in E.coli und Expressed Protein Ligation dargestellt. Nach Umsetzung des Thioesters 31 mit einem Alanyl-PNA-Peptid-Hybrid 29, das N-terminal mit einem freien Cystein substituiert ist, wurde durch native chemical ligation ein von dem humanen Interleukin 8 abgeleitetes 77 Aminos{\"a}uren enthaltendes Peptid 30 mit eingebauter Alanyl-PNA erhalten. Dar{\"u}ber hinaus wurden mit keinem, einem oder zwei Lysinen substituierte Alanyl-PNA-Hexamere dargestellt und Strukturuntersuchungen unterworfen. Es konnte mittels temperaturabh{\"a}ngiger UV-Spektroskopie gezeigt werden, dass der Einbau zweier Lysine sowohl die L{\"o}slichkeit als auch die Bildungskinetik ver{\"a}ndert, die Stabilit{\"a}t (Tm-Wert) der Duplexe jedoch unver{\"a}ndert l{\"a}sst. Diese Hexamere wurden Kristallisationsversuchen unterworfen, bisher konnten noch keine Kristalle erhalten werden. Basierend auf den im Rahmen dieser Arbeit erhaltenen Ergebnissen sollte es in Zukunft dar{\"u}ber hinaus m{\"o}glich sein, genaueren Aufschluss {\"u}ber die Struktur von Alanyl-PNA zu erhalten. Die Erh{\"o}hung der L{\"o}slichkeit von Alanyl-PNA durch Einbau zweier Lysine erm{\"o}glicht nicht nur weitere Kristallisationsversuche, sondern man gelangt auch in Konzentrationsbereiche, in denen NMR-Untersuchungen an Alanyl-PNA m{\"o}glich werden, die bisher aufgrund zu schlechter L{\"o}slichkeit zu keinen zufrieden stellenden Ergebnissen gef{\"u}hrt haben.

However, one diversity gradient is rarely assessed, namely how plant species distribute along the depth gradient of lakes. Here, we provide the first comprehensive characterization of depth diversity gradient (DDG) of alpha, beta, and gamma species richness of submerged macrophytes across multiple lakes. We characterize the DDG for additive richness components (alpha, beta, gamma), assess environmental drivers, and address temporal change over recent years. We take advantage of yet the largest dataset of macrophyte occurrence along lake depth (274 depth transects across 28 deep lakes) as well as of physiochemical measurements (12 deep lakes from 2006 to 2017 across Bavaria), provided publicly online by the Bavarian State Office for the Environment. We found a high variability in DDG shapes across the study lakes. The DDGs for alpha and gamma richness are predominantly hump-shaped, while beta richness shows a decreasing DDG. Generalized additive mixed-effect models indicate that the depth of the maximum richness (Dmax) is influenced by light quality, light quantity, and layering depth, whereas the respective maximum alpha richness within the depth gradient (Rmax) is significantly influenced by lake area only. Most observed DDGs seem generally stable over recent years. However, for single lakes we found significant linear trends for Rmax and Dmax going into different directions. The observed hump-shaped DDGs agree with three competing hypotheses: the mid-domain effect, the mean-disturbance hypothesis, and the mean-productivity hypothesis. The DDG amplitude seems driven by lake area (thus following known species-area relationships), whereas skewness depends on physiochemical factors, mainly water transparency and layering depth.

Perfusion alterations were evaluated on cerebral blood flow maps, blood-brain barrier disruption (BBBD) visually and quantitatively on ktrans maps and hemorrhagic transformation on susceptibility-weighted images. Visual BBBD within the DWI lesion corresponded to a median ktrans elevation (IQR) of 0.77 (0.41-1.4) min-1 and was found in all 7 cases of hypoperfusion (100\%), in 10 of 16 cases of hyperperfusion (63\%), and in only three of 13 cases with unaffected perfusion (23\%). BBBD was significantly associated with hemorrhagic transformation (p < 0.001). While BBBD alone was not a predictor of clinical outcome at 3 months (positive predictive value (PPV) = 0.8 [0.56-0.94]), hypoperfusion occurred more often in patients with unfavorable clinical outcome (PPV = 0.43 [0.10-0.82]) compared to hyperperfusion (PPV = 0.93 [0.68-1.0]) or unaffected perfusion (PPV = 1.0 [0.75-1.0]).
