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

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

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

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

New insights into the structure of a killer protein

Researchers have gained new insights into the structure of the killer protein Bax. The protein induces programmed cell death, the method by which the body disposes of cells that are no longer needed or have been pathologically altered. Since Bax is constantly changing its location in the cell, its structure is difficult to investigate. (Mehr in: Cancer News — ScienceDaily)

Uptake mechanisms of cytostatics discovered

How does a cytostatic like cisplatin or carboplatin actually get into the cell? Scientists have now succeeded in showing that the volume-regulated anion channel VRAC is 50 % responsible for active substance uptake. If one of the VRAC subunits LRRC8A or LRRC8D is down-regulated, cells take up considerably less of the anti-cancer drug. In addition to this finding, programmed cell death or apoptosis is also significantly disturbed when LRRC8A is missing. The researchers have thus identified a potential cause for therapy resistance, they suggest. (Mehr in: Cancer News — ScienceDaily)

Combination therapy may be more effective against the most common ovarian cancer

High-grade serous ovarian cancer often responds well to the chemotherapy drug carboplatin, but why it so frequently comes back after treatment has been a medical mystery. Now a team of researchers has discovered that a subset of tumor cells that don’t produce the protein CA125, a biomarker used to test for ovarian cancer, has an enhanced ability to repair their DNA and resist programmed cell death — which allows the cells to evade the drug and live long enough to regrow the original tumor.

Researchers discover molecular approach to promote cancer cell death

Lung cancer researchers have discovered a novel strategy to exploit apoptosis, a form of programmed cell death, for the treatment of lung cancer. The protein Bcl-2 is a known target for cancer treatment since it allows cancer cells to evade cell death via apoptosis. (Mehr in: Cancer News — ScienceDaily)

Mitochondria and the evolutionary roots of cancer

Cancer is a group of almost 200 diseases that involve variety of changes in cell structure, morphology, and physiology. Cancer phenotype is underlying several alterations in cellular dynamics with three most critical features, which includes self-sufficiency in growth signals and insensitivity to inhibitory signals, evasion of programmed cell death and limitless replicative potential with a potential for the invasion of other organs. Cancer disease is widespread among metazoans. Some properties of cancer cells such as uncontrolled cell proliferation, lack of apoptosis, hypoxia, fermentative metabolism and free cell motility, i.e. metastasis, resemble a prokaryotic lifestyle, which leads to the assumption of […]

A 150-year-old drug might improve radiation therapy for cancer

17. Okt. 2018

A drug first identified 150 years ago and used as a smooth-muscle relaxant might make tumors more sensitive to radiation therapy. Researchers found that the drug papaverine inhibits the respiration of mitochondria, the oxygen-consuming and energy-making components of cells, and sensitizes model tumors to radiation. They found that the drug does not affect the radiation sensitivity of well-oxygenated normal tissues. (Mehr in: Cancer News — ScienceDaily)

Researchers have developed an automated model that assesses dense breast tissue in mammograms — which is an independent risk factor for breast cancer — as reliably as expert radiologists. This marks the first time a deep-learning model of its kind has successfully been used in a clinic on real patients, according to the researchers.
