Basic research leads to a novel cancer therapy

... these tumour cell signalling cascades, because in cancers they are often disturbed. If there were a way to block growth factors, or the receptors on the cellular surface from tumour cells, that could lead to targeted therapies against cancers. Already in the 1980s, cancer researcher Axel Ullrich, then a sci...

Breast implants not associated with cancer risk, study reports

New compound protects against liver cancer

...O-Im could be particularly effective in preventing cancers with a strong link to inflammation, such as liver, colon, prostate and gastric cancers. It could also play a role in preventing diseases such as neurodegeneration, asthma and emphysema. The findings are featured in the February 15, 2006, issue of the...

New cellular flaw found in some virulent breast cancers

...control flaw is seen in about 10 percent of breast cancers ?and the deadliest ones. The cancer results from ... to treating this very aggressive cancer." Breast cancers composed of cells that contain both the overactive cyclin D1-CDK4 switch and a mutated cancer-causin...

Discovery of new molecular tools for biosynthesis could lead to advances in use of pectin

...ctins that could be specifically targeted to fight cancers in humans. (It has also been demonstrated that pectin lowers serum cholesterol levels.) While not the breakthrough that will allow immediate manipulation of total pectin biosynthesis, it is, one of the researchers involved said, "the first word of th...

Mayo Clinic collaboration discovers protein amplifies DNA injury signals

...mportant first step to designing new therapies for cancers and other diseases. Background Biology The damage control process is continual and essential to health. DNA must repair itself so the instructions it gives to operate bodily functions are correct. In earlier work, the Mayo Clinic researchers dete...

Nanotechnology may find disease before it starts

...logy to improve our ability to identify very early cancers and other diseases," said Jun Liu, a study co-author and an assistant professor of biomedical engineering at Ohio State University. "We ultimately want to identify disease at its cellular level, at its very earliest stage." The study is in the curre...

Infections could contribute to adult brain tumours

...unting for less than two per cent of all new adult cancers diagnosed in the UK each year. These findings suggest a possible link between infection and this type of the disease but by no means provide proof." *The team included UK and Dutch researchers. In the UK, they came from the University of Newcastle...

Marine mammals are on the frontline of failing ocean health

...een diagnosed with a urogenital cancer, similar to cancers we see in humans. Researchers found high levels of persistent organic pollutants (POPs) in these animals and believe contaminants, when combined with specific genetic traits and a herpes virus, are a key factor in causing the cancer. "We see the ...

Terahertz imaging may reduce breast cancer surgeries

...reast tissue, tumor and even early-stage 'in situ' cancers in excised tissue samples," said Vincent P. Wallace, Ph.D., lead investigator at TeraView, who worked with Addenbrooke's Hospital in Cambridge, England, in conducting the study. "This technology could aid the surgeon in immediately identifying residu...

BiovaxID?yields 89 percent survival in patients with aggressive non-Hodgkins

...e way to use vaccines in a number of hematological cancers that are treated by eliminating diseased B-cells." Biovest is now enrolling patients in a pivotal Phase 3 trial to test BiovaxID against follicular non-Hodgkin's lymphoma (NHL). Follicular NHL is an indolent (slow-growing) form of lymphoma not cons...

Liver cancer linked to cellular repair pathway

...y is also linked to certain brain, skin and muscle cancers and has recently been implicated in cancers of the pancreas, esophagus, lungs and prostate. The work by the Duke and Johns Hopkins team now adds...

Infection 'alarm' yields clues to immune system behavior

... rheumatoid arthritis and lupus. In addition, some cancers are more likely to grow where inflammation occurs. These ailments might be helped by a drug that curbs inflammation by reducing the sensitivity of IKK. Still other diseases that are characterized by a weak inflammatory response might be helped by a d...

Clawed frog helps Fanconi anemia research make leaps

...es that may someday lead to a treatment of certain cancers and for Fanconi anemia, a devastating disease that primarily affects children. The lab already joined forces with other labs to isolate several of the dozen genes known to exist in the Fanconi pathway. "Really, there are not a whole lot of labs usi...

'Virus chip' detects new virus in prostate tumors

... virus could be involved in some types of prostate cancers in men with mutated RNASEL genes. In the new study, the researchers discovered the novel virus far more often in human prostate tumors with two copies of the RNASEL gene mutation than in those with at least one normal copy. "This is a virus that h...

Parents need to be educated about HPV vaccinations for daughters

... are thought to be responsible for 70% of cervical cancers worldwide. "If the current vaccinations that are being developed are approved for use, then they could be used to vaccinate girls at puberty in order to prevent HPV infection. By preventing HPV infection, this could have the effect of preventing th...

Combination therapy improves AIDS-related lymphoma outcome

... as lymphoma patients without HIV. Lymphomas are cancers of the immune system's white blood cells. They are treated with chemotherapy, often consisting of a multi-drug regimen using cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP). People with HIV, a virus that depletes integral, specialize...
