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

Implications of quantum metabolism and natural selection for the origin of cancer cells and tumor progression

Energy transfer in material solids is driven primarily by differences in intensive thermodynamic quantities such as pressure and temperature. The crucial observation  in quantum-theoretical models was the consideration of the heat capacity as associated with the vibrations of atoms in a crystalline

Quantum Teleportation and Von Neumann Entropy

From the aspect of the quantum information theories, various quantum entropies are possibly computed at each stage, which ensures the emergence of the entangled states in the intermediate step. If a single qubit quantum teleportation is near the computational basis, the quantum measurement is domina

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

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

COX-2 inhibitors may reverse IDO1-mediated immunosuppression in some cancers

21. Jul. 2017

In preclinical studies, tumors that consitutively expressed the protein indoleamine 2,3-dioxygenase (IDO1) responded to the cyclooxygenase-2 (COX-2) inhibitor celecoxib (Celebrex) and had improved infiltration of certain subsets of T cells, making them more likely to respond to anti-PD1 therapies, report researcher.

Shooting the Achilles heel of nervous system cancers

20. Jul. 2017

Scientists have devised a strategy to target cancer cells while sparing normal cells by capitalizing on vulnerabilities that are exposed only in tumor cells. These vulnerabilities are known as the ‚Achilles heel‘ of cancer cells. Although much is known about the mutations that cause a cell to become malignant, little is known about these vulnerabilities.

Genetic predisposition to breast cancer due to non-BRCA mutations in Ashkenazi Jewish women

20. Jul. 2017

Genetic mutations in BRCA1 and BRCA2 increase the risk of breast and ovarian cancer in Ashkenazi Jewish women. A new article pexamines the likelihood of carrying another cancer-predisposing mutation in BRCA1, BRCA2 or another breast cancer gene among women of Ashkenazi Jewish ancestry with breast cancer who do not carry one of the founder mutations.

Molecular changes with age in normal breast tissue are linked to cancer-related changes

20. Jul. 2017

New research provides insight into how changes that occur with age may predispose breast tissue cells to becoming cancerous. Specifically, the study demonstrates that regions in the genome where DNA methylation changes occur with age are particularly sensitive to disruption in cancer. This new data provides insight into how certain molecular changes with age in normal breast tissue itself may contribute to breast cancer risk. (Mehr in: Cancer News — ScienceDaily)

How CD44s gives brain cancer a survival advantage

19. Jul. 2017

In the case of glioblastoma multiforme, the deadliest type of brain cancer, researchers have discovered that the molecule CD44s seems to give cancer cells a survival advantage. In the lab, eliminating this advantage by reducing the amount of CD44s resulted in cancer cells being more sensitive to the deadly effects of the drug erlotinib.
