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

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

About metabolism of a carcinoma cell

Most cancer cells utilize aerobic glycolysis irrespective of their tissue of origin. The alteration from oxidative phosphorylation to glycolysis – called the Warburg effect – is an universal phenomen and has now become a diagnostic tool for cancer detection. Warburg O, Posener K, Negelein E.

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

Wholeness and implicate order: “Deep” quantum chemistry and cell consciousness: quantum chemistry controls genes and biochemistry to give cells and higher organism’s consciousness and complex behavior

Bohm used the term ‘holomovement’ which is an unbroken and undivided totality and carries an implicate order which is he totality of an order including both the manifested and non-manifested aspects of the order. Non-local quantum phenomena reside in a subtler level than quantum level that is th

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

Environmental enrichment triggers mouse wound repair response

25. Apr. 2017

Living in a stimulating environment has a wide range of health benefits in humans and has even been shown to fight cancer in mice, but the underlying mechanisms have been unclear. A study now reveals that cognitive stimulation, social interactions, and physical activity increase lifespan in mice with colon cancer by triggering the body’s wound repair response.

Robot radiology: Low cost A.I. could screen for cervical cancer better than humans

24. Apr. 2017

Medical researchers have created a cervical cancer screening technique that, based on an analysis of a very large dataset, has the potential to perform as well or better than human interpretation on other traditional screening results, such as Pap tests and HPV tests–at a much lower cost. The technique could be used in less-developed countries, where 80% of deaths from cervical cancer occur. (Mehr in: Cancer News — ScienceDaily)

Does the microbiome play a role in the effectiveness of colorectal cancer treatment?

24. Apr. 2017

C. elegans, fed a diet of E. coli bacteria, are 100 times more sensitive to the chemotherapy drug floxuridine, commonly used to treat colon cancer, than worms fed different bacteria. These findings suggest that the bacteria residing in your digestive tract may play an important role in your ability to respond to chemotherapy. (Mehr in: Cancer News — ScienceDaily)

Novel molecular pathway in aggressive breast cancer offers potential therapeutic targets

21. Apr. 2017

A novel molecular mechanism involved in progression and metastasis in the most aggressive form of breast cancer has now been identified by researchers. The gene MAFK is known to be induced by the TGF-? signaling pathway, which is involved in breast cancer development. The team reported that MAFK protein, in turn, induced cancerous behaviors in cells by switching on the breast cancer-associated gene GPNMB. MAFK thus represents a link between TGF-? signaling and GPNMB-induced breast cancer. (Mehr in: Cancer News — ScienceDaily)

Mapping DROSHA’s cleavage sites

20. Apr. 2017

Each cell of our body is the result of an orchestra of sophisticated mechanisms that control which genes are and are not expressed at any given time. Partly, this is possible thanks to the coordination of several types of RNA molecules, like microRNAs (miRNAs). Researchers have developed a new technique called fCLIP-seq that analyzes the miRNA fragments created by the RNA-cleaving protein DROSHA. It is expected that this study will open up new pathways to understand the role of DROSHA in such important biological phenomena. (Mehr in: Cancer News — ScienceDaily)
