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.

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

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

A 150-year-old drug might improve radiation therapy for cancer

A drug first identified 150 years ago and used as a smooth-muscle relaxant might make tumors more sensitive to radiation therapy. Researchers found that the drug papaverine inhibits the respiration of mitochondria, the oxygen-consuming and energy-making components of cells, and sensitizes model tumors to radiation. They found that the drug does not affect the radiation sensitivity of well-oxygenated normal tissues. (Mehr in: Cancer News — ScienceDaily)

Chemotherapy may lead to mitochondrial dysfunction in skeletal muscle

Chemotherapy drugs to treat breast cancer may promote muscle mitochondrial dysfunction, according to new research. Dysfunctional mitochondria, the energy centers of the cells, may contribute to fatigue and weakness that some people with breast cancer experience through the course of disease treatment.

Proof of Concept: Gene therapy for mitochondrial diseases

Mitochondrial disease is now thought to be the second most commonly diagnosed genetic disease worldwide, and, unfortunately, there are still no proven treatment strategies for those diagnosed. Scientists from the Max Planck Institute for Biology of Ageing in Cologne were involved in collaborations to apply gene-therapy approaches in mice to successfully treat an animal model of mitochondrial disease. This may pave the way for future therapeutic strategies for patients. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

Proof of Concept: Gentherapie bei mitochondrialen Erkrankungen

Mitochondriale Erkrankungen zählen heute zu den zweithäufigsten diagnostizierten genetischen Erkrankungen weltweit, und leider gibt es immer noch keine bewährten Behandlungsstrategien. Wissenschaftler des Max-Planck-Instituts für Biologie des Alterns in Köln haben nun in einer Kooperationsarbeit einen Gentherapieansatz an Mäusen angewandt, der zu einer erfolgreichen Behandlung der Mitochondrienerkrankung in diesen Tieren führte. Damit wurde der Weg für zukünftige therapeutische Strategien am Menschen geebnet. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

„Science“-Study: Proteins surf to mitochondria – Novel transport pathway discovered

Proteins are essential constituents of cells and their compartments. Prof. Johannes Herrmann, a researcher at the Technische Universität Kaiserslautern, and his team discovered a novel mechanism by which newly synthesized proteins reach their respective target compartment in the cell. Proteins destined to mitochondria, the cell’s powerhouse, are not directly transported to mitochondria but are directed to the surface of the endoplasmic reticulum, where they “surf” along its surface. As shown in the renowned journal “Science”, this so far unknown mechanism keeps newly synthesized protein transport-competent and might prevent their aggregation.
