Study reveals genetic link to colon cancer

03.11.2004


Mutation indicates risk of acquiring disease



Researchers from the Samuel Lunenfeld Research Institute at Mount Sinai Hospital have determined that the mutation of a specific gene in some patients with colon cancer indicate a risk of acquiring the disease. The study appears in the Nov. 3 edition of the Journal of the National Cancer Institute. The research team, led by Dr. Steven Gallinger used a population based study to determine that when one parent had the MutY human homologue (MYH) gene and there was also a family history of acquiring the disease then it may account for a fraction of hereditary colorectal cancers.

The child of a couple that has one MYH gene carrier has a 1:2 risk of carrying the mutation and this translates into increased risk of developing the disease. "This is going to contribute to new knowledge of colon cancer and it may impact who goes for testing," said Dr. Gallinger, a researcher and surgeon. He is also a professor of surgery at the University of Toronto.


The study suggests this information to be used in the identification of potential high risk cases to see if screening and further testing of the patient and family members is required. This research builds on previous studies that suggest the child of a couple where both parents are carriers has a 1:4 chance of developing a severe form of colon cancer. As many as 20 per cent of colorectal cancer patients have a family history of the disease.

The population based study followed 1238 patients with colorectal cancer and 1255 healthy control subjects from Ontario. Compared to non-carriers, the MYH gene carriers had a higher risk of acquiring colorectal cancer.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
