A new theory of the origin of cancer: quantum coherent entanglement, centrioles, mitosis, and differentiation

Low non-specific, low intensity laser illumination (635, 670 or 830 nm) apparently enhances centriole replication and promotes cell division, what is the opposite of a desired cancer therapy. In the contrary, centrioles are sensitive to coherent light. Then higher intensity laser illumination - stil

Chromatin opening elements allow tetracycline inducible gene expression in stem cells

In modern biomedicine, cell therapeutics are produced from reprogrammed stem cells (induced pluripotent stem cells, iPS). For this purpose, these cells can also undergo an additional genetic modification. However, unintentional mechanisms frequently occur, which can deactivate gene expression. Researchers from the Paul-Ehrlich-Institut (PEI) have developed inducible vectors containing ubiquitous chromatin opening elements (UCOE) which keep the relevant gene modified locus permanently open so that it remains active. The journal Biomaterials reports on these results in its online version of 24 November 2018. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

Chromatin-öffnende Elemente erlauben Tetrazyklin-induzierbare Genexpression in Stammzellen

In der modernen Biomedizin werden aus reprogrammierten Stammzellen (induzierte pluripotente Stammzellen, iPS) Zelltherapeutika hergestellt. Hierzu können diese Zellen im späteren Verlauf noch zusätzlich genetisch modifiziert werden. Allerdings treten häufig unbeabsichtigte Mechanismen auf, welche die Genexpression stilllegen. Forschende des Paul-Ehrlich-Instituts (PEI) haben induzierbare (aktivierbare) Vektoren entwickelt, die mit Hilfe eines Chromatin-öffnenden Elements (UCOE, ubiquitious chromatin opening element) den relevanten genmodifizierten Abschnitt dauerhaft offen und damit aktiv halten. Über die Forschungsergebnisse berichtet die Zeitschrift Biomaterials online vorab am 24.11.18. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

Chromatin structure mutes enhancer activity

In early embryos it is not possible to distinguish between arms and legs: their developmental precursors are virtually identical. Dynamic changes in the 3D structure of the chromatin in the leg precursor cells bring the Pen enhancer into spatial proximity to the Pitx1 gene, thus enabling the activation of this critical gene specifically in the future leg. As a result, forelimb and hindlimb buds subsequently differentiate from each other and produce arms and legs, respectively. This surprising molecular mechanism has been discovered by scientists around Stefan Mundlos and Guillaume Andrey from the Max Planck Institute for Molecular Genetics and the […]

Chromatin-Struktur legt Enhancer still

Im frühen Embryo lässt sich nicht erkennen, was ein Arm wird und was ein Bein: Die Knospen für die Extremitäten sehen zunächst identisch aus. Durch dynamische Veränderungen in der 3D-Struktur des Chromatins wird bei den unteren Extremitätenknospen der Enhancer Pen in räumliche Nähe zu dem Gen Pitx1 gebracht und kann es aktivieren. So erwachsen aus den oberen Knospen Arme und aus den unteren Beine. Den erstaunlichen molekularen Mechanismus haben Wissenschaftlerinnen und Wissenschaftler um Guillaume Andrey und Stefan Mundlos vom Max-Planck-Institut für molekulare Genetik und der Charité – Universitätsmedizin Berlin entdeckt und jetzt im renommierten Fachblatt „Nature Genetics“ veröffentlicht.

3D structure of DNA forms defined room for dissociated lncRNAs to activate gene expression

Enhancers are regulatory regions of the DNA, giving rise to “long non-coding RNAs” (lncRNAs), which are known as crucial regulators of gene expression. Scientists from the Max Planck Institute for Molecular Genetics in Berlin now have shown that a lncRNA called A-ROD is only functional the moment it is released from chromatin into the nucleoplasm. In the current issue of Nature Communications the researchers demonstrate that the regulatory interaction requires dissociation of A-ROD from chromatin, with target specificity ensured within the pre-established chromosomal proximity. This can heavily influence our understanding of dynamic regulation of gene expression in biological processes. (Mehr […]

3D-Struktur der DNA bildet umschriebenen Raum zur Aktivierung der Genexpression durch freie lncRNAs

Forscher/innen des Max-Planck-Instituts für molekulare Genetik (MPIMG) in Berlin konnten zeigen, dass eine lncRNA namens A-ROD nur funktionstüchtig ist, wenn sie vom Chromatin in das Kernplasma abgegeben wird. In der aktuellen Ausgabe der Zeitschrift Nature Communications beschreiben die Wissenschaftler/innen, dass sich A-ROD vollständig vom Chromatin ablösen muss, um regulatorisch aktiv werden zu können. Durch die dreidimensionale Struktur der DNA wird gewährleistet, dass sich A-ROD bei der Ablösung bereits in direkter Nähe zu seinem Zielgen befindet. Dies kann unser Verständnis der dynamischen Regulation der Genexpression in biologischen Prozessen stark beeinflussen. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

Improved understanding of the pathology of dwarfism may lead to new treatment targets

Pseudoachondroplasia (PSACH) is a severe inherited dwarfing condition In PSACH, a genetic mutation leads to abnormal retention of cartilage oligomeric matrix protein (COMP) within the endoplasmic reticulum (ER) of cartilage-producing cells (chondrocytes), which interferes with function and cell viability. Investigators describe how this protein accumulation results in ‚ER stress‘ and initiates a host of pathologic changes. These findings may open up new ways to treat PSACH and other ER-stress-related conditions. (Mehr in: Cancer News — ScienceDaily)
