Genetic testing could improve breast cancer prevention — ScienceDaily

Their study showed that prevention strategies could be improved by testing not only as currently for major cancer predisposition genes such as BRCA1 and BRCA2 — which identify a small percentage of women at very high risk — but also by factoring in data on multiple gene variants that individually have only a small effect on risk, but are more common in the population. The research was carried out by researchers at The Institute of Cancer Research, London, and the National Cancer Institute in Bethesda, US — and is published in the Journal of the National Cancer Institute. The study received funding from The Institute of Cancer Research (ICR), Breakthrough Breast Cancer and the National Cancer Institute. Researchers stressed that their study was a computer modelling analysis and would need to be confirmed by further research aimed at validating the models they used and assessing real-life prevention approaches…

Cheap malaria drug could treat colorectal cancer effectively too, say experts

A pilot study by researchers at St George’s, University of London, has found the drug artesunate, which is a widely used anti-malaria medicine, had a promising effect on reducing the multiplication of tumour cells in colorectal cancer patients who were already going to have their cancer surgically removed. Colorectal cancer (CRC) makes up about 10 percent of the annual 746,000 global cancer cases in men and 614,000 cases in women. …

Establishment of induced pluripotent stem cells from Werner syndrome fibroblasts

Werner syndrome is characterized by the premature appearance of features associated with normal aging and cancer predisposition. This syndrome occurs frequently in Japan, affecting 1 in 20,000 to 1 in 40,000 people. The therapeutic methods for this disease are very limited and it is expected that iPS cells can be used for the development of innovative therapies…

Metabolic ‘reprogramming’ by p53 gene family leads to tumor regression

The University of Texas MD Anderson Cancer Center investigation showed that, in vivo, the genes p63 and p73 can be manipulated to upregulate or increase levels of IAPP, a protein important for the body’s ability to metabolize glucose. IAPP is found in some diabetes drugs already on the market. The research findings were published in today’s issue of Nature. …

Technology developed to improve lung cancer detection, treatment

John Roeske, PhD, and colleagues presented how they developed and evaluated the technology at the recent annual meeting of the American Society for Therapeutic Radiology and Oncology. Their approach uses dual-energy imaging combined with fluoroscopy to view tumors during radiation therapy. This technology does not require an X-ray that produces both high-and low-energy images. Existing hardware can be used to eliminate visuals of the ribs and other bones making it easier to see the tumor…

Cutting-edge computer software helps pinpoint aggressiveness of breast cancer tumors

Their findings are published today in the journal, Nature Scientific Reports. “We are using a unique software program in our lab that looks at a type of mutation called a splicing mutation that is typically overlooked using current methods,” said lead author on the study, Stephanie Dorman, a PhD student in the department of biochemistry at Western University’s Schulich School of Medicine & Dentistry. She said that where previous genetic studies of 445 tumours detected 429 of these splicing mutations, the Western-developed analysis software was able to find more than 5000. Using this software and human tumour tissue sample genetic data from The Cancer Genome Atlas, the research team pinpointed that mutations in the Neural Cell Adhesion Molecule (NCAM) and other related genes in NCAM biology were present at a much higher rate in tumours which had metastasized to the lymph nodes than those that did not…

New imaging technique identifies receptors for targeted cancer therapy

“Protein overexpression is a hallmark of certain cancers and is used in clinical oncology to personalize treatment through tumor detection, molecular therapies, and therapeutic monitoring,” said lead author Kimberley S. Samkoe, assistant professor of Surgery at the Geisel School of Medicine and adjunct assistant professor at Thayer School of Engineering. “Protein expression is currently measured through a total protein analysis of tumor tissue. This new technique allows us to accurately determine the amount of protein receptors available for binding a drug without invasive biopsy.” The researchers developed a dual-tracer in vivo receptor concentration imaging (RCI) technique that involves the simultaneous injection of both a targeted and a non-targeted imaging agent. …

Scoring scheme predicts ability of cancer cells to spread to other parts of body

Led by Professor Jean Paul Thiery, Senior Principal Investigator, and Dr Ruby Huang, Principal Associate, both from CSI Singapore, the scientists developed a scoring scheme which monitors the epithelial-mesenchymal transition (EMT) mechanism. This process was shown to play a role in a large number of cancer-related events, including cancer invasion, metastasis, and chemo-resistance…
