Variation in cancer risk among tissues can be explained by the number of stem cell divisions

Tomasetti and Vogelstein show that the lifetime risk of cancers of many different types is strongly correlated with the total number of divisions of the normal self-renewing cells maintaining that tissue’s homeostasis. These results suggest that only a third of the variation in cancer risk among t

Quantum Tunnelling to the Origin and Evolution of Life

Quantum tunnelling is a phenomenon which becomes relevant at the nanoscale and below. It is a paradox from the classical point of view as it enables elementary particles and atoms to permeate an energetic barrier without the need for sufficient energy to overcome it. Tunnelling is being of vital imp

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

Insight into development of lung cancer

Lung cancer results from effects of smoking along with multiple genetic components. A new study identifies two main pathways for the role of chromosome 15q25.1 — a leader in increasing susceptibility to lung cancer — in modifying disease risk. One pathway is implicated in nicotine dependence. The other plays a part in biological processes such as nutrient transfer and immune system function. The findings increase our understanding of lung cancer cause and development. (Mehr in: Cancer News — ScienceDaily)

Ein Fall von „Kiss and Tell“: Chromosomales Kissing wird fassbarer

Chromosomen sind im Zellkern unterschiedlich verteilt; ihre Anordnung und Kommunikation miteinander sind bislang kaum verstanden. Forschungsteams aus Berlin und Jena veröffentlichen nun im EMBO Journa,l welchen Effekt strukturelle Chromosomenaberrationen auf die Organisation des Genoms (Chromosomal Kissing) und auf den Krankheitsverlauf haben.

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 […]

The role of ‚extra‘ DNA in cancer evolution and therapy resistance

Researchers tracked genomic alterations detected in patient samples during tumor cell evolution in culture, in patient-derived xenograft (PDX) mouse models from the cultures, as well as before and after treatment in patients. The team reports that tumor progression was often driven by cancer-promoting genes, known as oncogenes, on extrachromosomal pieces of DNA. (Mehr in: Cancer News — ScienceDaily)

Faltkunst im Zellkern

Strukturelle Chromosomen-Mutationen können die Faltung der DNA im Zellkern beeinflussen und zu einer Fehlregulation von Genen führen. Wissenschaftler/innen des Max-Planck-Instituts für molekulare Genetik (MPIMG) in Berlin haben gemeinsam mit Physiker/innen der Universität Neapel Verfahren für Vorhersagen entwickelt, ob und wie solche Struktur-Varianten die dreidimensionale Faltung der Chromosomen verändern. Damit wollen die Forscher/innen herausfinden, ob bestimmte Mutationen die Genregulation beeinflussen und so Krankheiten verursachen können.

Folding art in the nucleus

Structural variants can influence the folding of DNA in the nucleus and thus lead to a misregulation of genes. Now, scientists at the Max Planck Institute for Molecular Genetics (MPIMG) in Berlin together with physicists of the University of Naples, Italy, have developed methods to predict, whether and how such structural variants might alter the three-dimensional folding of the chromosomes. With these methods, the researchers want to predict if specific mutations influence gene regulation and can cause diseases. Their long-term goal is to better understand the so far puzzling causes of congenital malformations in order to improve the diagnosis of […]

Wechselkröten zeigen: Arten mit vielfachen Genomen haben lediglich entfernt verwandte Vorfahren

Die meisten Wirbeltiere haben zwei Chromosomensätze, einen von der Mutter und einen vom Vater – auch wir Menschen sind diploid. Viel seltener ist die Polyploidie, also der Besitz von drei oder mehr Chromosomensätzen. Um die Entstehung neuer Wirbeltierarten zu erforschen, studieren EvolutionsbiologInnen Wechselkröten – diese können diploid oder polyploid sein. Dr. Matthias Stöck vom Leibniz-Institut für Gewässerökologie und Binnenfischerei und ForscherInnen der Universität Lausanne und des Helmholtz-Zentrums für Umweltforschung haben einen Stammbaum für die eurasischen Wechselkrötenarten vorgelegt: Die polyploiden Arten stammen von Elternlinien mit sehr geringem Verwandtschaftsgrad ab.

Studying mitosis‘ structure to understand the inside of cancer cells

Cell division is an intricately choreographed ballet of proteins and molecules that divide the cell. During mitosis, microtubule-organizing centers assemble the spindle fibers that separate the copying chromosomes of DNA. While scientists are familiar with MTOCs‘ existence and the role they play in cell division, their actual physical structure remains poorly understood. Researchers are now trying to decipher their molecular architecture. (Mehr in: Cancer News — ScienceDaily)
