Scientists one step closer to cancer vaccine

...rs can vaccinate and protect against the spread of tumours from different tissues, including melanoma, colon cancer, lymphoma, and fibrosarcoma. "So far we've only conducted research on mice, so it's too early to get out hopes up too much," says research scientist Elisabeth Wolpert at the Microbiology and T...

Mobile phone use not linked to increased risk of glioma brain tumours

...udy. A significantly increased risk was found for tumours which developed on the same side of the head as th...his finding may be due to people with glioma brain tumours linking mobile phone use to the side of the tumour and therefore over reporting the use of a phone o...

Clues to breast cancer hidden inside stem cells

...g. In the human breast, up to 20 per cent of all tumours are now suspected to originate in stem cells. Now scientists from the Icelandic Cancer Society and the Faculty of Medicine, University of Iceland have grown three-dimensional breast cell cultures to reveal unexpected subtleties about these stem cells...

Infections could contribute to adult brain tumours

...and Dutch team* analysed a database of adult brain tumours diagnosed in patients from the North Brabant provi...id: "Very little is known about the cause of brain tumours and we think our research brings us closer to understanding more about this disease. "We only fou...

Sensors, a smart dose of medicine for cancer treatment

...ves clinical outcomes by more accurately targeting tumours and minimising the amount of radiation absorbed by healthy tissue. The result is that patients only receive a high radiation dose where they need it and healthy tissue is preserved. The problem with IMRT so far, however, is that it becomes increasi...

Cheap, rapid hand-held check for HIV

...4+ cells, which orchestrate the immune response to tumours and infections, is a sure sign that HIV is damaging a person's health: some clinical definitions of AIDS say that once a person's CD4+ count falls below 200 cells per microlitre of blood, he or she has developed the condition. Doctors rely on CD4+ ...

Young scientists turn to gel to ease side-effects of cancer treatment

...d the gel which will help doctors to target cancer tumours more efficiently. Now, the group has secured £30,000 under the Bioscience Yorkshire Enterprise Fellowship scheme to commercialise their idea. Their product, a formulation of various chemicals, is a gelatine whose density is comparable with human t...

Microarray technology for tailoring breast cancer therapy

Scientists discover genetic pathway responsible for breast cancer cell growth

...author of the paper. "It is found in breast cancer tumours that express the estrogen receptor." In their study, the researchers found that the FOXA1 gene was required for the estrogen receptor to activate the growth of breast cancer cells. "By inactivating the FOXA1 gene in laboratory cell cultures, we were...

Next Generation Body Scanner Launched By The University Of Manchester

...tients, they will be able to look at the way brain tumours and cancers grow and develop and how different kinds of treatment might work. It will also help researchers looking into strokes and will enable them to understand the way the brain recovers in stroke patients. The scanner will also benefit rese...
