MicroRNA 'sponges' could aid cancer studies
08-12-2007 · Massachusetts Institute of Technology (MIT)MIT researchers have developed a new way to study the function of microRNA, the tiny strands of genetic material that help regulate a cell's genes. The work could shed light on microRNA's hypothesized role in tumor development.

- Study finds association between low cholesterol levels and cancer
07-23-2007 · EurekAlert!
Millions of Americans take statins to lower their cholesterol, but how low should you go? Many scientific studies support the benefits of lowering low-density lipoprotein (LDL) cholesterol, and achieving low LDL cholesterol levels is one of the most important steps in preventing heart disease. New research, however, provides evidence for an association between low LDL levels and cancer risk.

- Penn study points to new direction for pancreas cell regeneration
04-03-2007 · EurekAlert!
Past studies in tissue culture have suggested that one type of pancreas cell could be coaxed to transform into insulin-producing islet cells. Now, researchers at the University of Pennsylvania School of Medicine have demonstrated that these pancreatic acinar cells do not become insulin-producing cells in an animal model. However, they did show that injured pancreatic cells readily regenerate back into healthy acinar cells, which has implications for treating cancer and inflammation of the pancreas.

- Genetic marker linked to aggressive prostate cancer
05-20-2007 · EurekAlert!
Northwestern University researchers have discovered that a recently identified genetic marker for prostate cancer is linked to a highly aggressive form of the disease. These findings ultimately will aid the development of a simple blood test to predict who is susceptible to this aggressive cancer. Knowing which patients carry this genetic marker also will guide doctors in how they treat the cancer. The study showed a strong hereditary component to this aggressive cancer.

- MR spectroscopy identifies breast cancer, reduces biopsies
09-25-2007 · EurekAlert!
Proton magnetic resonance spectroscopy used in conjunction with magnetic resonance imaging can aid radiologists in diagnosing breast cancer while reducing the number of false-positive results and invasive biopsies, according to a study focusing on nonmass-enhancing breast lesions. The study, conducted at Memorial Sloan-Kettering Cancer Center in New York City, appears in the October issue of the journal Radiology.

- Insights into cell movement likely to aid immune study, cancer research
01-07-2008 · EurekAlert!
Scientists at Washington University School of Medicine in St. Louis have used yeast cells to better understand a collection of proteins associated with the formation of actin networks, which are essential to cell movement. The cell's ability to move is important to a broad range of biomedical concerns, including understanding how immune system cells pursue disease-causing invaders and how metastasizing cancer cells migrate from a tumor.

- Kaiser Permanente study: Alcohol amount, not type -- wine, beer, liquor -- triggers breast cancer
09-27-2007 · EurekAlert!
New Kaiser Permanente study, one of largest individual studies of the effects of alcohol on the risk of breast cancer, concludes it makes no difference whether a woman drinks red wine, white wine, beer or hard liquor, it is the alcohol itself (ethyl alcohol) and the quantity consumed that triggers the onset of cancer. The study of 70,033 multi-ethnic women is the first to look at whether alcohol types makes difference on breast cancer.

- Study finds outcomes of high-risk cancer operations in 80-year-olds worse than reported
12-18-2007 · EurekAlert!
New research published in the December issue of The Journal of the American College of Surgeons shows that outcomes of high-risk cancer operations in 80-year-olds are considerably worse than reported in case studies and published survival statistics, which may lead to unrealistic expectations about the safety of these operations in the elderly.

- Study of African traditional medicine will begin world-first clinical trial
12-06-2007 · EurekAlert!
Sutherlandia may be unfamiliar to many North Americans, but in South Africa, where traditional medicines are used by many people, and often supplement conventional medicines, many consider it a miracle plant. Those that use Sutherlandia claim it cures ailments from depression to cancer. Sutherlandia is the focus of research at the International Center for Indigenous Phytotherapy Studies, led by the University of Missouri and the University of the Western Cape in South Africa.

- Men with prostate cancer avoid radiation due to misconceptions
11-05-2006 · EurekAlert!
Negative perceptions about radiation therapy can strongly influence a prostate cancer patient's choice to avoid external beam radiation therapy, even though studies have proven the treatment to be as safe and effective as other treatments for the disease, including surgery, according to a study presented November 5, 2006, at the American Society for Therapeutic Radiology and Oncology's 48th Annual Meeting in Philadelphia.

- Micro molecules can identify pancreatic cancer
01-10-2007 · EurekAlert!
A pattern of micro molecules can distinguish pancreatic cancer from normal and benign pancreatic tissue, new research suggests. The study examined human pancreatic tumor tissue and compared it to nearby normal tissue and control tissue for levels of microRNA (miRNA). It identified about 100 different miRNAs that are present usually at very high levels in the tumor tissue.
