Bacterium that may cause cancer is identified

10.12.2002


A University of Sheffield scientist has isolated a bacterium that may cause cancers in those with a genetic pre-disposition to the disease.



Dr Milton Wainwright, of the University’s Molecular Biology and Biotechnology department, researched historical literature and found that, as early as the 1890s, bacteria were believed to cause cancer. Unfortunately, none of the bacteria involved in these studies were ever kept or even named, making it impossible to verify claims about their role in cancer. Dr Wainwright has now isolated a bacterium that is in many ways similar to these historical isolates; the same bacterium was also linked to cancer during the 1960s, but then ignored. The results of this work will be published in the forthcoming issue of Medical Hypotheses.

Dr Wainwright says, “Most cancer experts remain sceptical of the idea that microbes (with the exception of viruses) can cause cancer in humans. Despite this, bacteria have recently been implicated in stomach and cervical cancer. The isolate is a strain of Bacillus licheniformis, a fairly common bacterium that shows a remarkable ability to change its shape. This ability may help it induce cancer in those people with a genetic predisposition to the disease. There is no fear, however, that cancer can in any way be caught from patients.”


“This discovery may have real importance for the future because if bacteria, including this isolate, do cause cancer then we may be able to arrest the disease using antibiotics or vaccines. Hopefully, this and other studies will lead to more research effort and money being directed towards the microbial theory of cancer.”

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
