Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) belong to a spectrum of neurodegenerative diseases with overlapping symptoms, characterized by muscle wasting, paralysis, dementia, and other serious impairments. There are currently no effective treatments. Many patients have a common hallmark: A protein called TDP-43 clumps together in the neurons of the brain to form tiny lumps. Researchers at DZNE and Ulm University Hospital, together with international experts, have now discovered that these pathological changes primarily affect certain cells.

Amyotrophe Lateralsklerose (ALS) und Frontotemporale Demenz (FTD) gehören zu einem Spektrum neurodegenerativer Erkrankungen mit überlappender Symptomatik, die durch Schwund der Muskulatur, Lähmungen, Demenz und andere schwerwiegende Beeinträchtigungen gekennzeichnet ist. Wirksame Behandlungsmöglichkeiten gibt es bislang nicht. Eine Gemeinsamkeit auf molekularer Ebene teilen viele Betroffene: Ein Protein namens TDP-43 ballt sich in den Nervenzellen des Gehirns zu winzig kleinen Klumpen. Forschende des DZNE und des Universitätsklinikums Ulm haben gemeinsam mit Fachleuten aus dem Ausland nun festgestellt, dass diese krankhaften Veränderungen vorwiegend bestimmte Zellen betreffen.

A certain blood protein regarded as an early indicator of Alzheimer’s disease also appears to play a role in other disorders. Researchers at DZNE and the Hertie Institute for Clinical Brain Research (HIH) at the University of Tübingen have found that elevated levels of phosphorylated tau protein (pTau) also occur in two lesser-known conditions that primarily affect the heart and kidneys. These findings open up new perspectives for improved diagnostics and were published this week in the journal “Nature Medicine”. They are based on data from 280 older individuals from Germany, Italy, and the Netherlands. Quelle: IDW Informationsdienst Wissenschaft

• An international research team led by Prof. Dr. Thomas Ott, professor at the University of Freiburg and member of the Cluster of Excellence CIBSS – Centre for Integrative Biological Signalling Studies, has demonstrated for the first time that the protein SYFO2, found in the roots of leguminous plants, makes it possible for the plants to ‘fertilize themselves’. • The researchers also succeeded in activating the tomato’s own version of SYFO2. This opens up new perspectives for research on how the need for fertilizer on crops could be reduced in the future. • The study was published in the journal…

• Ein internationales Forschungsteam um Prof. Dr. Thomas Ott, Mitglied des Exzellenzclusters CIBSS, hat erstmals gezeigt: Das in Wurzeln von Hülsenfrüchten vorkommende Protein SYFO2 ermöglicht die „Selbstdüngung“ der Pflanzen. • Den Forschenden ist es zudem gelungen, die tomateneigene Version von SYFO2 zu aktivieren. Das eröffnet neue Perspektiven auf die Frage, wie der Einsatz von Düngemitteln bei Nutzpflanzen künftig reduziert werden könnte. • Die Studie wurde im Fachmagazin Science veröffentlicht.

Protein activity can be precisely regulated via subtle changes in temperature using heat-sensitive switches. Underlying this capability is a novel modular design strategy developed by researchers at the Institute of Pharmacy and Molecular Biotechnology of Heidelberg University. The strategy allows the integration of sensory domains in various proteins regardless of function or spatial structure. This new Heidelberg approach in the field of thermogenetics is broadly applicable and opens up new possibilities for precise, non-invasive control of different cellular processes.

Muhammad A Shah, Emily L Denton, Cheryl H Arrowsmith, Mathieu Lupien and Matthieu Schapira Abstract Background The notion that epigenetic mechanisms may be central to cancer initiation and progression is supported by recent next-generation sequencing efforts revealing that genes involved in chromatin-mediated signaling are recurrently mutated in cancer patients. Results Here, we analyze mutational and transcriptional profiles from TCGA and the ICGC across a collection 441 chromatin factors and histones. Chromatin factors essential for rapid replication are frequently overexpressed, and those that maintain genome stability frequently mutated. We identify novel mutation hotspots such as K36M in histone H3.1, and uncover…

Bohm used the term ‘holomovement’ which is an unbroken and undivided totality and carries an implicate order which is he totality of an order including both the manifested and non-manifested aspects of the order. Non-local quantum phenomena reside in a subtler level than quantum level that is the quantum potential which sustains intimately within the underlying implicates order and the quantum processes are driven by information from quantum potential. A global quantum field of a cell, which can be described as a super orbital, provides many levels of interactions among all particles of a cell. From quantum metabolism pint of…

Daniel Smeets, Yolanda Markaki, Volker J Schmid, Felix Kraus, Anna Tattermusch, Andrea Cerase, Michael Sterr, Susanne Fiedler, Justin Demmerle, Jens Popken, Heinrich Leonhardt, Neil Brockdorff, Thomas Cremer1, Lothar Schermelleh and Marion Cremer Abstract Background A Xist RNA decorated Barr body is the structural hallmark of the compacted inactive X territory in female mammals. Using super-resolution three-dimensional structured illumination microscopy (3D-SIM) and quantitative image analysis, we compared its ultrastructure with active chromosome territories (CTs) in human and mouse somatic cells, and explored the spatio-temporal process of Barr body formation at onset of inactivation in early differentiating mouse embryonic stem cells (ESCs)….

Susanne Rittinghausen, Anja Hackbarth, Otto Creutzenberg, Heinrich Ernst, Uwe Heinrich, Albrecht Leonhardt and Dirk Schaudien Abstract Background Biological effects of tailor-made multi-walled carbon nanotubes (MWCNTs) without functionalization were investigated in vivo in a two-year carcinogenicity study. In the past, intraperitoneal carcinogenicity studies in rats using biopersistent granular dusts had always been negative, whereas a number of such studies with different asbestos fibers had shown tumor induction. The aim of this study was to identify possible carcinogenic effects of MWCNTs. We compared induced tumors with asbestos-induced mesotheliomas and evaluated their relevance for humans by immunohistochemical methods. Methods A total of 500…
