Although patients with early stage, small, breast tumours have an excellent short term prognosis, more than 15 to 20 per cent of them will eventually develop distant metastases, and die from the disease. Vascular invasion — through lymphatic and blood vessels — is the major route for cancer spreading to regional lymph nodes and to the rest of the body.
Dr Stewart Martin, Professor Ian Ellis and their colleagues at The University of Nottingham, and worldwide, are combining a number of approaches in a dynamic effort to improve our understanding of cell behaviour in breast cancer. Discovering how these cells operate is vital in improving diagnosis and treatment for the cancer patient in the longer term, and in identifying therapeutic targets. Already the results of their work have been excellent — with findings in relation to the spread of cancer through the lymphatic vessels prompting a much larger study funded by Cancer Research UK.
A research student within the Nottingham team, Rabab Mohammed, showed recently that specific factors that regulate the growth of blood and lymphatic vessels can identify a subset of tumours which have a high probability of recurring or spreading.
The team subsequently identified the crucial importance of assessing both the level of blood and lymph vessel invasion by cancer cells at the earliest stages of detection. It has, until recently, been very difficult to distinguish between the two. With advances in immunohistochemical techniques, blood vessels can today be reliably identified and differentiated from lymphatics. Currently clinical approaches for the assessment of vascular invasion are insufficiently robust and can result in a failure to detect some lesions accurately, or fail to differentiate adequately between blood and lymph vessels. The Nottingham team has shown — using tumour sections from 177 patients — that 96 per cent of vascular invasion in primary invasive breast cancer is predominantly of the lymph vessels. This is significant.
It is important that this finding is verified in a larger cohort of patients. The researchers are now working to accomplish this, through funding recently obtained from Cancer Research UK, using specimens from more than a thousand women with early stage breast cancer. Results from this study will also allow them to determine whether Lymphatic Vascular Invasion can be incorporated into an improved prognostic index for early stage breast cancer.
This work is being combined with gene expression studies, with bioinformatic approaches and using in vitro (cells in culture) models to identify novel therapeutic targets. It is being conducted in collaboration with a number of groups, industrial and academic, from both the UK and overseas.

Penn study identifies new malaria parasites in wild bonobos

Heat from the friction of rocks caused by tidal forces could be the “engine” for the hydrothermal activity on Saturn's moon Enceladus. This presupposes that...
The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
