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

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 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

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

A Mitochondrial Paradigm of Metabolic and Degenerative Diseases, Aging, and Cancer: A Dawn for Evolutionary Medicine

Progressive increase in mtDNA 3243A>G heteroplasmy causes abrupt transcriptional reprogramming Wallace hypothesized mitochondrial dysfunction as a central role in a wide range of age-related disorders and various forms of cancer. Steadily rising increases in mitochondrial DNA mutations cause abr

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

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

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

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 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

Detailed images of tumor vasculature

18. Apr. 2018

Thanks to a new method of analyzing ultrasound images, conventional scanners can be used for generating high-res images of blood vessels in tumors. This approach makes it easier to distinguish between different types of tumors, and it facilitates the tracking of the progress and success of chemotherapy. (Mehr in: Cancer News — ScienceDaily)

T cell antigen receptors act alone: Longstanding immunological mystery solved

18. Apr. 2018

With a standard electron microscope, only dead T cells can be studied. Therefore, it is very hard to figure out the inner workings of the cell. New microscopy techniques, making it possible to study living T cells, have now led to surprising results: while it has been generally believed that T cell receptors must interact with one another for effective immune-signaling, the new study shows: T cell receptors act alone.

Can a simple blood test rule out lung cancer?

17. Apr. 2018

A blood test to measure the levels of two proteins in plasma that are common predictors of lung cancer was 98 percent effective in a multicenter clinical trial at distinguishing benign from malignant lung nodules when combined with a patient’s clinical characteristics to form an integrated classifier.

Efficient control of leukemia with treatment by dual immune-checkpoint blockade

17. Apr. 2018

Chronic lymphocytic leukemia (CLL) is a hematological malignancy. When infiltrating tissues, CLL cells come in contact with healthy cells, including immune cells. Researchers have now characterized the composition of immune cells and circulating cytokines of the CLL microenvironment in mouse models using mass cytometry. Based on this knowledge, they propose an immunotherapeutic strategy with two immune checkpoint inhibitors that efficiently blocks disease development in preclinical tests.

Possible novel method for stopping untreatable pediatric brain cancers

17. Apr. 2018

Researchers used an experimental molecular therapy in preclinical laboratory tests to effectively treat several types of deadly pediatric brain cancer and now propose advancing the treatment to clinical testing in children. Scientists report testing the small molecule 6-thio-2’deoxyguanosine (6-thio-dG) in brain cancer stem cells derived from tumor cells donated by patients. Researchers also tested the treatment in humanized mouse models of pediatric brain cancer. (Mehr in: Cancer News — ScienceDaily)
