A protein that functions as a cancer drug for leadership in animal experiments has been developed by an international team that includes several researchers from the University of Western Australia.

The natural protein is known to play an important role in promoting cell death (for example in mammary cells after the young are weaned), prevention of cell proliferation, promoting cell differentiation, and in this new discovery, by blocking the formation of blood vessels.

The trial results, published in the American Journal of Pathology showed that the protein – related protein secreted curly 4 (sFRP4) – inhibits tumors in the same degree as a very successful antibody, Avastin ®.

Winthrop Professor Arun Dharmaraj UWA School of Anatomy and Human Biology and UWA, said Anna University (AU), Chennai, India, holders of patents on the use of sFRP4 as angiogenesis inhibitor and are eager to find a trading partner for project.

Scientists have found a way to identify patients with breast cancer are likely to respond to a type of chemotherapy. The new test also predict that is unlikely to see the benefit of treatment and help save them from unnecessary side effects.

The results – presented by researchers at the European Cancer Conference in Spain – that doctors should be able to tailor treatment to patients who will benefit and avoid the administration of toxic drugs for those not rescued.

In conducting a review of four large studies of breast cancer, researchers have discovered an abnormality on chromosome 17, called CEP17 is an indicator of “very important” that the tumor response to chemotherapy with anthracyclines call.

The ability of cancer cells resistant to treatment with targeted therapies or conventional chemotherapy in some cases, the result of a transient state of reversible drug “tolerance.” In an article published in the April 2 issue of Cell, researchers from Massachusetts General Hospital (MGH) Cancer Center announce the presence of small populations of drug-tolerant cells of various types of tumors and identify aspects of the underlying mechanism.

“Despite resistance to anticancer drugs may result from preexisting rare genetic mutations that occur in response to treatment, the accumulation of evidence has done in other non-genetic mechanisms of potentially irreversible,” said Jeffrey Settleman, PhD , of the MGH Cancer Center, who led the study. “In cell lines derived from different types of cancer are subpopulations of cells that display an ability to transition to tolerate exposure to toxic drugs, which has been associated with structural changes in the DNA of cells and suggests a therapeutic strategy that could prevent developing resistance. ”

Women diagnosed with breast cancer within 12 months after pregnancy are 48 percent more likely to die than other young women with breast cancer, according to a survey by the University of Western Australia.

However, in a study of 3,000 breast cancer patients younger than 45 years, found that if the cancer is diagnosed during pregnancy, your risk of death was only a three percent higher than non-pregnant women with cancer.

Research Assistant Professor Angela Ives at UWA Cancer and Palliative Care Research and Evaluation has shown that very little is known about gestational breast cancer (cancer diagnosed during pregnancy or even a year later.)

“We decided to learn more to enable women to make informed decisions about your cancer treatment and pregnancy,” he said. With his colleagues, Associate Professor / Professor Yves analyzed statistics from Western Australia’s data link system – one of the few such systems in the world.
