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

Quantum entanglement between the electron clouds of nucleic acids in DNA

Rieper, Anders and Vedral modelled the electron clouds of nucleic acids in a single strand of DNA as a chain of coupled quantum harmonic oscillators with dipole-dipole interaction between nearest neighbours. As a main result, the entanglement contained in the chain coincides with the binding energy

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

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

How cells combat chromosome imbalance

Biologists have now identified a mechanism that the immune system uses to eliminate genetically imbalanced cells from the body. (Mehr in: Cancer News — ScienceDaily)

‚Hail Mary‘ mechanism can rescue cells with severely damaged chromosomes

Safeguards for maintaining the integrity of chromosomes during cell growth and division can fail, and a cell may find itself trying to divide into two daughter cells with a loose chromosomal fragment drifting away from a broken chromosome. Researchers are studying a remarkable mechanism that carries broken chromosomes through the process of cell division so that they can be repaired and function normally in the daughter cells.

Tracking unstable chromosomes helps predict lung cancer’s return

Scientists have found that unstable chromosomes within lung tumors increases the risk of cancer returning after surgery, and have used this new knowledge to detect relapse long before standard testing. (Mehr in: Cancer News — ScienceDaily)

The role of a telomere capping complex in cancer revealed

Scientists have unveiled part of the protein complex that protects telomeres—the ends of our chromosomes. Telomeres are the protective structures at the end of chromosomes and are essential for the faithful replication and protection of our genome. Defects in telomere function can lead to genomic instability in cancer, while the gradual shortening of telomeres is associated with the aging of human cells. (Mehr in: Cancer News — ScienceDaily)

Study helps explain varying outcomes for cancer, Down Syndrome

Disorders caused by aneuploidy, a condition in which cells contain an abnormal number of chromosomes, can vary widely in severity from one individual to another. New research shows that aneuploidy alone can cause this significant variability in traits, in otherwise genetically identical cells. (Mehr in: Cancer News — ScienceDaily)

Telomere length predicts cancer risk

The length of the ‚caps‘ of DNA that protect the tips of chromosomes may predict cancer risk and be a potential target for future therapeutics. Longer-than-expected telomeres — which are composed of repeated sequences of DNA and are shortened every time a cell divides — are associated with an increased cancer risk.

AML study correlates gene mutations with 34 disease subgroups

A large, new study of adults with acute myeloid leukemia (AML) correlates 80 cancer-related gene mutations with five subtypes of AML, which are defined by the presence of specific chromosomal abnormalities.

Dreidimensionale "Landkarte" zeigt Genomstruktur von Stammzellen

Damit die rund zwei Meter lange DNA in einem einzigen Zellkern Platz finden kann, muss sie sich falten. Dieser Aufwand kann nur in mehreren Etappen – von der Doppelhelix zu ganzen Chromosomen – bewerkstelligt werden. Aus dem Faltungsprozess ergeben sich unterschiedliche dreidimensionale Strukturen des Genoms, die miteinander interagieren und so zelluläre Prozesse beeinflussen. Erstmals gelang es ForscherInnen um Martin Leeb von den Max F. Perutz Laboratories (MFPL) der Universität Wien, gemeinsam mit der Universität Cambridge, die 3D-Strukturen des Genoms von Säugetieren in einzelnen Zellen zu klären. Die Resultate wurden in der renommierten Fachzeitschrift „Nature“ veröffentlicht. (Mehr in: Pressemitteilungen – idw […]

How well do we understand the relation between incorrect chromosome number, cancer?

Researchers report surprising results of experiments intended to explore the consequences of having too many or too few chromosomes, a phenomenon that biologists call aneuploidy. They were surprised to find that having one extra chromosome actually supresses cancer, contrary to long-held belief. (Mehr in: Cancer News — ScienceDaily)
