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

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

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

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

The great feeding-frenzy: Species-rich food webs produce biomass more efficiently

Frankfurt, Oct 05th, 2016. Researchers at the Senckenberg have discovered a feedback in food webs: species-rich ecosystems favor large, heavy animals. Even though this increases the amount of plants consumed, the plant biomass remains approximately at the same level as in species-poor ecosystems. This is due to the fact that in species-rich ecosystems, plant communities develop whose growth is more energetically efficient. The extent of biomass production in species-rich ecosystems is more stable and thereby predictable whereas species loss leads to unpredictable deficiencies, which would have to be compensated by humans, according to the paper, published today in “Nature Communications.” (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

How body may detect early signs of cancer

26. Jul. 2017

Fresh insights into how cells detect damage to their DNA — a hallmark of cancer — could help explain how the body keeps disease in check. Scientists have discovered how damage to the cell’s genetic material can trigger inflammation, setting in motion processes to remove damaged cells and keep tissues healthy.

Biomarkers for identifying tumor aggressiveness

26. Jul. 2017

Future early-stage colon cancer patients could benefit from specific genetic tests that forecast their prognosis and help them make the right decision regarding chemotherapy. Two of the biomarkers are the MACC1 gene, high levels of which promote aggressive tumor growth and the development of metastasis, and a defective DNA mismatch repair (dMMR) system, which plays a role in tumor formation. Life expectancy is longer for patients with dMMR tumors and with low MACC1 gene activity. (Mehr in: Cancer News — ScienceDaily)

Explaining failure of retinoic acid trials against breast cancer: Timing key

26. Jul. 2017

Estrogen-positive breast cancers are often treated with anti-estrogen therapies. But about half of these cancers contain a subpopulation of cells marked by the protein cytokeratin 5 (CK5), which resists treatment — and breast cancers with higher CK5 expression have poorer prognosis. These cells, which have characteristics of stem cells, often survive treatment to drive or even restart cancer growth. Previous work has shown that retinoic acid, a chemical that results from the body’s natural breakdown of vitamin A, should act against these CK5+ cells, but clinical trials of retinoids against breast cancer have been largely unsuccessful.

Reversing tissue damage caused by heart attacks?

25. Jul. 2017

A new discovery helps to explain how cells which surround blood vessels, called pericytes, stimulate new blood vessels to grow with the hormone ‚leptin‘ playing a key role. Leptin is produced by fat cells which helps to regulate energy balance in the body by inhibiting the appetite. This study may have important implications for the treatment of heart attacks and also for cancer. (Mehr in: Cancer News — ScienceDaily)
