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.

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 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

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

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

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 in

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

Treatment of cancer could become possible with adenovirus

Researchers have shown that adenovirus binds to a specific type of carbohydrate that is overexpressed on certain types of cancer cells. The discovery opens up new opportunities for the development of virus-based cancer therapy. (Mehr in: Cancer News — ScienceDaily)

Potential guidance for gastric cancer treatment

14. Aug. 2018

Researchers have discovered that gastric cancer tissue samples bearing mutation of a specific gene, MUC16, too are associated with higher tumor mutation loads. Also known as tumor mutation burdens, measurement of high genetic mutation rates among cancerous versus healthy tissue has increasingly been shown to correlate with effective response rates to immunotherapy. The knowledge could bode positively for patients with the biomarker present. (Mehr in: Cancer News — ScienceDaily)

Cetuximab+RT found to be inferior to standard treatment in HPV+ oropharyngeal cancer

14. Aug. 2018

An interim analysis of data from a randomized clinical trial of patients with human papillomavirus (HPV)-positive oropharyngeal cancer found that treatment with radiation therapy and cetuximab is associated with worse overall and progression-free survival compared to the current standard treatment with radiation and cisplatin. The trial was designed to see if cetuximab with radiation would be less toxic than cisplatin with radiation without compromising survival for patients with the disease.

Specialized delivery methods to help treat cancer, other disorders

13. Aug. 2018

More than 100 years ago, German Nobel laureate Paul Ehrlich popularized the ‚magic bullet‘ concept — a method that clinicians might one day use to target invading microbes without harming other parts of the body. Although chemotherapies have been highly useful as targeted treatments for cancer, unwanted side effects still plague patients. Now, researchers have demonstrated that specialized nucleic acid-based nanostructures could be used to target cancer cells while bypassing normal cells. (Mehr in: Cancer News — ScienceDaily)

Medical testing: Drop the C-word to reduce anxiety and overtreatment

13. Aug. 2018

Medical researchers are calling for the word ‚cancer‘ to be dropped from some doctor-patient conversations in a bid to reduce patient anxiety and harm from over treatment. The appeal follows mounting evidence that patients who are told they have ‚cancer‘ for low risk conditions more often choose surgery than those whose condition is described with terms such as ‚lesions‘ or ‚abnormal cells‘.

‚Undruggable‘ cancers slowed by targeting growth signals

13. Aug. 2018

As many as 50 percent of human cancer cases — across a wide variety of tissues — involve defects in a common cellular growth signaling pathway. These defects have so far defied most attempts to develop targeted therapies. Now researchers have identified a new strategy for potentially treating intractable cancers by decoupling the entire RAS/MAP Kinase (MAPK) signaling pathway from external growth signals.
