How inflammatory proteins can protect against cancer

13.06.2008
Our body has a better way of protecting itself against cancer than previously recognised. Inflammatory proteins help to prevent the progression of a benign tumour to a malignant one.

This is reported by Dr. Daniel Peeper and his colleagues from the Netherlands Cancer Institute - Antoni van Leeuwenhoek Hospital (NKI-AVL) in the June 13 issue of the prominent scientific journal Cell.

The cells in our body are exposed to numerous factors that can inflict damage to the genetic material (DNA). Usually, these errors are repaired. Sometimes, however, a change is incorporated into the DNA. If such a mutation localises to a so-called oncogene, a cell can be stimulated to divide, and a benign tumour can arise. Previously, the research group of Dr. Peeper showed that this does not necessarily result in the generation of a malignant tumour. They discovered that benign tumours can activate a permanent growth arrest, such that they enter a hibernation-like state (Nature, Aug 4th 2005). This hibernation represents a natural barrier against cancer.

In the present follow-up study, Thomas Kuilman, a PhD student in Dr. Peeper’s research laboratory, delineated the mechanism behind this hibernation in benign tumours. He compared the activity of thousands of genes in dividing and dormant tumour cells and discovered a specific DNA fingerprint. Unexpectedly, this revealed that in non-dividing tumour cells, dozens of genes that normally play a role in inflammatory reactions of the body, are activated.

In collaboration with Dr. Lucien Aarden (Sanquin), the researchers subsequently used advanced techniques to show that inflammatory proteins are essential to keep benign tumour cells in a non-proliferating state. Finally, together with Dr. Wolter Mooi (VUmc) the researchers showed that these inflammatory proteins are likely to play an important role in the natural defence against colon 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.
