Die neue Achillesferse von Blutkrebs

18. Mai. 2018

Akute myeloische Leukämie ist eine aggressive Form von Blutkrebs, sie zählt zu den häufigsten Kinderkrebsarten. AML-Zellen tragen oft Mutation in einem bestimmten Gen, dessen Funktion von einem komplexen Netzwerk aus Protein-Interaktionen abhängt. Mit einer Kombination hochmoderner Analyseverfahren aus dem Bereich der Genomik und Proteomik ist es WissenschaftlerInnen des CeMM und des LBI CR gelungen, ein Protein in diesem Netzwerk zu identifizieren, das entscheidend für das Überleben der AML-Zellen ist.

Mitochondria and the evolutionary roots of cancer

23. Feb. 2015

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 reversal like evolution from eucariotic back to proteobacterial state. This phenotype matches the phenotype of the last universal common ancestor (LUCA) that resulted from the endosymbiosis between archaebacteria and α-proteobacteria, which later became the mitochondria.

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 abrupt shifts in diseases. Discrete changes in nuclear gene expression in response to small increases in DNA mutant level are analogous to the phase shifts that is well known in physics: As heat is added, the ice abruptly turns to water or with more heat abruptly to steam. Therefore, a quantitative change that is an increasing proportion of mitochondrial DNA mutation results in a qualitative change  which coordinate changes in nuclear gene expression together with discrete changes in clinical symptoms.

Variation in cancer risk among tissues can be explained by the number of stem cell divisions

23. Feb. 2015

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 tissues is attributable to environmental factors or inherited predispositions. The majority is due to bad luck, that is, random mutations arising during DNA replication in normal, noncancerous stem cells.

Implications of quantum metabolism and natural selection for the origin of cancer cells and tumor progression

23. Feb. 2015

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 solid. However, living organisms are essentially isothermal. Because of very little differences in temperature between different parts of a cell it is assumed that energy flow in living organisms is mediated by differences in the turnover time of various metabolic processes in the cell, which occur in cyclical fashion. It has been shown that the cycle time of these metabolic processes is related to the metabolic rate, that is the rate at which the organism transforms the free energy of whatever source into metabolic work, maintenance of constant temperature and structuraland functional organization of the cells. Quantum Metabolism exploits the methodology of the quantum theory of solids to provide a molecular level which derives new rules relating metabolic rate and body size.

Quantum entanglement between the electron clouds of nucleic acids in DNA

23. Feb. 2015

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 of the molecule. Derived in the limit of long distances and periodic potentials analytic expressions linking the entanglement witnesses to the energy reduction due to the quantum entanglement in the electron clouds.

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

23. Feb. 2015

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 the quantum potential which sustains intimately within the underlying implicates order and the quantum processes are driven by information from quantum potential. A global quantum field of a cell, which can be described as a super orbital, provides many levels of interactions among all particles of a cell. From quantum metabolism pint of view all electrons that are contained in one system are inseparable from eachother. In a cell the cytoplasm is a gel made of up to 30% proteins, and the structure of this gel is very much like a liquid crystal which provides collective properties of the electrons.

All these electrons within this super orbital of molecules and co-enzymes of the cell, including all the many small molecules embedded in these large biomolecules, and cofactors transporting electrons are making up one huge structure that is a global cell orbital.

Quantum Tunnelling to the Origin and Evolution of Life

23. Feb. 2015

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 importance for life: physical and chemical processes can be traced directly back to the effects of quantum tunnelling. These processes include the   prebiotic chemistry as well as the function of biomolecular nanomachines and has many highly important implications that can be derived from to the field of molecular, prebiotic chemistry and biological evolution, respectively.

Quantum Teleportation and Von Neumann Entropy

23. Feb. 2015

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 dominantly responsible for the joint entropy at the final stage. If it is far from the computational basis, this dominant responsibility is moved into the quantum measurement of system. Therefore, the relative entropy can be regarded as a measure for distance between two different quantum states like trace distance or fidelity. Some relative entropies become infinity, which indicates the non-trivial intersection of the support of one quantum state with kernel of the other quantum state.

A new theory of the origin of cancer: quantum coherent entanglement, centrioles, mitosis, and differentiation

23. Feb. 2015

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 – still below heating threshold – may selectively target centrioles, impair mitosis and be a beneficial therapy against malignancy. If centrioles utilize quantum photons for entanglement, properties of centrosomes/centrioles approached more specifically could be useful for therapy. Healthy centrioles for a given organism or tissue differentiation should then have specific quantum optical properties detectable through some type of readout technology. An afflicted patient’s normal cells could be examined to determine the required centriole properties which may then be used to generate identical quantum coherent photons administered to the malignancy. In this mode the idea would not be to destroy the tumor – relatively low energy lasers would be used – but to “reprogram” or redifferentiate the centrioles and transform the tumor back to healthy well differentiated tissue.
