McGill researchers link enzyme to breast cancer malignancy

03.12.2007
Discovery will help develop new drug treatments

McGill University researchers have uncovered the crucial role played by the enzyme focal adhesion kinase (FAK) in the onset of breast cancer. The research, led by Dr. William Muller – along with colleagues from McGill and the Beatson Institute for Cancer Research in Scotland – was published the week of November 26 in the Proceedings of the National Academy of Sciences (PNAS). The study's first author is Dr. Hicham Lahlou, a post-doctoral fellow in Dr. Muller's lab.

Using transgenic mice with pre-existing cancers, the McGill team was able to disable the function of FAK in the mammary gland. "When we did that, we basically blocked tumour progression in our mouse model," said Dr. Muller, Professor of Biochemistry at McGill, Canada Research Chair in Molecular Oncology and a researcher with the Molecular Oncology Group at the McGill University Health Centre (MUHC). "This shows that FAK, which was already linked to tumour growth in skin carcinomas, is very critical for tumour progression from a pre-malignant to a malignant state in the mammary tumour system."

Dr. Muller and his team made a similar breakthrough with an earlier discovery in 2004, when they showed that the protein beta1-integrin was similarly critical in the initiation of tumour growth and development of breast cancer in genetically engineered mice. Likewise, when this gene was blocked, cancerous tumours ceased to grow. The current discovery about FAK is an exciting sequel to the earlier research, says Dr. Muller, because, unlike beta1-integrin, kinase enzymes are eminently "druggable" with current technology.

Dr. Muller cautions that this study – like the Beatson Institute's earlier research linking FAK to tumour progression in skin carcinomas – is still preliminary. "However, developing an FAK inhibitor would certainly add another weapon to the arsenal for dealing with breast cancer," he said.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
