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

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

Unexpected regulation of transcription factors critical to development

Developmental biologists have for the first time described how two transcription factors that are ‚absolutely essential for human development‘ are regulated by a cell surface metalloprotease known as ADAM13. The discovery adds to knowledge of how cells migrate in vertebrate embryos, how stem cells differentiate and how cancer cells metastasize. (Mehr in: Cancer News — ScienceDaily)

Doctors gain a greater understanding of skin cancer using tattoos

Cancer is on the rise and the need to be empathetic when giving a patient their diagnosis and throughout treatment is imperative. Now, a collaborative study, with a Huddersfield professor, has enabled future doctors to experience some of the challenges patients living with skin cancer can face to develop a greater empathy for their patients.

Glass fronts can be acoustic illusions for bats

Sometimes bats perceive a smooth, vertical surface as an open pathway. A dangerous error in times of buildings with glass facades. The smooth surface reflects the echolocation calls away from the bat until shortly before collision and therefore acts like an acoustic mirror. Researchers of the Max Planck Institute for Ornithology in Seewiesen studied echolocation and flight behaviour of three bat species experimentally and in the wild while they tryed to fly through a smooth, vertical plate. However, bats seemingly also manage to avoid these collisions. Here, the number of echolocation calls and the time the animals spent in front […]

Oestrogen regulates pathological changes of bones via bone lining cells

The female sex hormone oestrogen protects the structural stability of bones. To date, however, it had been unclear exactly which cells were involved in the hormone’s protective function in preventing changes in bone density. Researchers at Vetmeduni Vienna were able to show for the first time that oestrogen uses a certain cell type as a “mediator” for its beneficial effects on bone. When oestrogen binds to these so-called “bone lining cells”, which cover the bone surfaces, it regulates the expression of a protein called RANKL in these cells. Oestrogen deficiency leads to uncontrolled expression of RANKL, which can trigger pathological […]

Combining CAR T cells with existing immunotherapies may overcome resistance in glioblastomas

Genetically modified “hunter” T cells successfully migrated to and penetrated a deadly type of brain tumor known as glioblastoma (GBM) in a clinical trial of the new therapy, but the cells triggered an immunosuppressive tumor microenvironment and faced a complex mutational landscape that will need to be overcome to better treat this aggressive cancer, researchers report.

Melanoma, a cancer of skin pigment cells called melanocytes, will strike an estimated 87,110 people in the US in 2017, according to the Centers for Disease Control and Prevention. A fraction of those melanomas come from pre-existing moles, but the majority of them come from sources unknown — until now. (Mehr in: Cancer News — ScienceDaily)

Researchers release the brakes on the immune system

18. Okt. 2017

Many tumors possess mechanisms to avoid destruction by the immune system. For instance, they misuse the natural “brakes” in the immune defense mechanism, which normally prevent an excessive immune response. Researchers have now been able to take off one of these brakes. The study could pave the way for more effective cancer therapies, they say. (Mehr in: Cancer News — ScienceDaily)

Battling flames increases firefighters‘ exposure to carcinogens

18. Okt. 2017

The threat of getting burned by roaring flames is an obvious danger of firefighting, but other health risks are more subtle. For example, firefighters have been found to develop cancer at higher rates than the general population. Now researchers have measured how much firefighters‘ exposure to carcinogens and other harmful compounds increases when fighting fires. Their study also points to one possible way to reduce that exposure. (Mehr in: Cancer News — ScienceDaily)
