Genetics may play a role in the success of anti-cancer therapy, according to researchers at the Research Institute of the McGill University Health Centre (MUHC) and the Lady Davis Institute for Medical Research of the Sir Mortimer B. Davis - Jewish General Hospital. Their study, published in todays issue of Clinical Cancer Research, shows that some colorectal cancer patients with a particular gene mutation respond much better to therapy than those without this genetic change.
"Our findings are important," says Dr. Rima Rozen acting Scientific Director of the Research Institute of the MUHC and senior author. "They demonstrate that colorectal cancer patients who have a particular genetic change, the MTHFR variant, will respond better to fluoropyrimidine-based chemotherapy than those patients without this genetic mutation. This suggests that therapy should be individualized. Patients with the MTHFR variant should be identified and appropriate chemotherapy should be administered."
"This finding may provide hope to the 10% to 15% of colorectal cancer patients who have the MTHFR variant" says co-author Dr. Victor Cohen, oncologist at the Sir Mortimer B. Davis-Jewish General Hospital (JGH) and researcher at the JGHs Lady Davis Institute (LDI) for Medical Research. "Although these are preliminary findings, they suggest these patients will respond well to fluoropyrimidine-based chemotherapy and consequently may have a better prognosis. Larger scale studies are needed to determine the long term consequence of having this gene variant."

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:...
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...
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...
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...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
