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.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
