Fish fat kills cancer cells

14.10.2002


Fatty acids from fish oils and fatty fish can destroy the power station - the mitochondria- in certain types of cancer cells, making the cells commit suicide.These are the conclusions in a new thesis that Hilde Heimli at the Institute for Nutrition Research at the University of Oslo, in Norway, presented in October 2002. The study was supported by the Norwegian Cancer Society.



Kreft.no: In her thesis, Hilde Heimli has examined how polyunsaturated omega-3 fatty acid is ingested by different leukemia/lymphoma cell lines. The researcher has examined how some types of cancer cells commit suicide in this setting, in other words programmed cell death or apoptosis.

Activated by an enzyme
If omega-3 fatty acids are to be capable of killing cancer cells, the cells have to contain a certain enzyme, that activate these certain fatty acids. Cancer cells that contain less of this enzyme do not react to fish fat.



"Polyunsaturated fatty acids from fish also can initiate a less regulated cell death called necrosis. The reason for the necrotic cell death is an increased production of reactive oxygen species in the cells. It is possible to appose this necrosis by the presence of antioxidants such as Vitamin C and E," says Hilde Heimli to www.kreft.no

Can prevent cancer
This work contributes to an increased understanding of how cancer cells grow and develop. This knowledge may play an important role in the prevention and treatment of certain types of cancer. Heimli’s experiments are developed from cancer cell lines – cells that originally came from leukemia patients,but she doesn’t see any reason that cancer cells of other origins shouldn’t commit suicide when exposed to fish fat.

So far - laboratory experiments
"The experiments have been done in dishes in a laboratory setting. The polyunsaturated fatty acids that are used are eicosapentaenoic acid (EPA),which are the same type as found in fatty fish or regular fish oil capsules.

The fatty acids are added to the the food given to the cancer cells in a way that is most like the body’s own process," says Heimli.

The basic knowledge from this work contributes to a larger understanding of growth regulation in cancer cells.

As a final result, one believes that this new knowledge can be used in the prevention and treatment of certain types of cancer.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

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...

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.
