It is one of the leading causes of cancer death - largely due to the failure of current histological procedures in predicting the recurrence of the disease. New research published in BioMed Central's open access journal BMC Cancer shows that a four-gene signature may accurately predict which patients are at higher risk of OSCC recurrence.
A team of researchers, including Drs. Patricia Reis and Levi Waldron, and led by Dr Suzanne Kamel-Reid and Dr. Igor Jurisica, from the Ontario Cancer Institute at University Health Network (UHN) Toronto, Canada collected cancerous and noncancerous oral tissue samples from patients with OSCC from Toronto General Hospital at UHN. They then used a meta-analysis of five published microarray studies along with their own microarray analysis to reliably identify 138 genes commonly over-expressed in both OSCC and normal margin tissues. Of these genes, a four-gene signature with the highest predictive risk of recurrence was selected. This signature contained cell invasion related genes MMP1, COL4A1, P4HA2 and THBS2.
The researchers explained, "Our data suggest that histologically normal surgical resection margins that over-express MMP1, COL4A1, THBS2 and P4HA2 are indicative of an increased risk of recurrence in OSCC. Patients at higher risk of recurrence could potentially benefit from closer disease monitoring and/or adjuvant post-operative radiation treatment, even in the absence of other clinical and histopathological indicators. Our findings may be applied to develop a molecular test, which could be clinically useful to help predict which patients are at a higher risk of local recurrence."

Researchers uncover protein-based “cancer signature”

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:...

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,...
