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

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

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

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

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

Researchers have discovered a mechanism that allows cancer to survive without glucose

New research provides important clues that might help understand the resistance to drugs that ‚starve‘ tumors, and also how cancer cells manage to survive in the center of the tumor mass, where barely any blood vessels can reach. (Mehr in: Cancer News — ScienceDaily)

Tracking unstable chromosomes helps predict lung cancer’s return

26. Apr. 2017

Scientists have found that unstable chromosomes within lung tumors increases the risk of cancer returning after surgery, and have used this new knowledge to detect relapse long before standard testing. (Mehr in: Cancer News — ScienceDaily)

Fighting cancer with immunotherapy: Signaling molecule causes regression of blood vessels

26. Apr. 2017

Immunotherapy with T-cells offers great hope to people suffering from cancer. Some initial successes have already been made in treating blood cancer, but treating solid tumors remains a major challenge. The signaling molecule interferon gamma, which is produced by T-cells, plays a key role in the therapy. It cuts off the blood supply to tumors, as a new study reveals.

Genes need to be screened for stem cell transplants

26. Apr. 2017

As stem cell lines grow in a lab dish, they often acquire mutations in the TP53 (p53) gene, an important tumor suppressor responsible for controlling cell growth. New research findings suggest that genetic sequencing technologies should be used to screen for mutated cells in stem cell cultures, so that cultures with mutated cells can be excluded from experiments and therapies.

HIPPO’s molecular balancing act helps nerves not short circuit

26. Apr. 2017

It may be possible to therapeutically fine tune a constantly shifting balance of molecular signals to ensure the body’s peripheral nerves are insulated and functioning normally, researchers have discovered. They suggest this may be a way to treat neuropathies or prevent the development of peripheral nerve sheath tumors. (Mehr in: Cancer News — ScienceDaily)

Ancient stress response provides clues to cancer resistance

25. Apr. 2017

Cancer cells deploy an ancient mechanism used by single-celled organisms to elevate their mutation rate in response to stress. This discovery explains one of the best-known hallmarks of cancer — its high mutation rate, which contributes to the rapid evolution of drug resistance. (Mehr in: Cancer News — ScienceDaily)

High rate of tumor shrinkage among pancreatic cancer patients

25. Apr. 2017

Adding cisplatin to standard gemcitabine/nab-paclitaxel drug treatment provided a very high rate of tumor shrinkage for patients with advanced pancreatic cancer, according to the results of a pilot clinical trial. These statistically significant and clinically meaningful improvements in overall response and survival rates resulted from a phase Ib/II clinical study. (Mehr in: Cancer News — ScienceDaily)

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)

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)
