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

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

Researchers unlock mechanism of drug resistance in aggressive breast cancer

20. Jan. 2017

Scientists report findings of how triple negative breast cancer cells are able to bypass treatment with trametinib, a U.S. Food and Drug Administration-approved drug that belongs to a class of commonly used anti-cancer drugs called kinase inhibitors. The researchers also reported findings from laboratory models of breast cancer testing a potential treatment approach that could prevent the onset of resistance.

New genetic engineering technique could help design, study biological systems

20. Jan. 2017

A new technique will help biologists tinker with genes, whether the goal is to turn cells into tiny factories churning out medicines, modify crops to grow with limited water or study the effects of a gene on human health. The technique allows scientists to precisely regulate how much protein is produced from a particular gene. The process is simple yet innovative and, so far, works in everything from bacteria to plants to human cells. (Mehr in: Cancer News — ScienceDaily)

Small intestine GIST associated with better prognosis in younger patients

18. Jan. 2017

Gastrointestinal stromal tumors (GIST) are tumors that arise is the wall of the digestive tract, and most often occur in the stomach or small intestine. Though more common in later in life, GISTs can occur in adolescents and young adults (AYA) under 40 years old as well. Researchers report findings from the first population-based analysis of AYA patients with GIST. (Mehr in: Cancer News — ScienceDaily)

Preclinical research sheds light on tumor-progression in lung cancer

17. Jan. 2017

Preclinical research shows that the tumor-promoting properties of neuropilin-2 reside predominantly on isoform NRP2b, while NRP2a has the opposite effects in non-small cell lung cancer. In mouse models, NRP2a inhibited tumor cell proliferation, while NRP2b promoted metastasis and progression. This new understanding may lead to improved therapies that specifically target NRP2b, while sparing the tumor-inhibiting functions of NRP2a. (Mehr in: Cancer News — ScienceDaily)
