Droplet Array Sheds Light On Drug-Resistant Cancer Stem Cells
5/10/2012
Researchers at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have developed a miniaturized biochip for investigating the effect of drugs on cancer stem cells (CSCs). Published recently in Nano Today, this new technology could boost the development of more effective cancer drugs...
A System Needed To Improve Cancer Screening
5/10/2012
An editorial by Marcus Plescia, MD, MPH, director of the Division of Cancer Prevention and Control at the Centers for Disease Control and Prevention (CDC), calls for a more organized and comprehensive approach to increase cancer screening participation among those who are insured or are likely to become insured through the Patient Protection and Affordable Care Act...
Poor women and African Americans with ovarian cancer are less likely to receive the highest standards of care, leading to worse outcomes than among white and affluent patients, according to a study of 50,000 women presented by UC Irvine's Dr. Robert Bristow at the Society of Gynecologic Oncology's annual meeting...
Potent New Drug Kills Tumor Cells In Mice By Clogging Up Their Recycling System
5/10/2012
All cells have the ability to recycle unwanted or damaged proteins and reuse the building blocks as food. But cancer cells have ramped up the system, called autophagy, and rely on it to escape damage in the face of chemotherapy and other treatments...
Breast And Colon Cancer Survivors Live Longer When Physically Active
5/10/2012
Physical activity is associated with reduced breast and colon cancer mortality, but there is insufficient evidence on the association for other cancer types, according to a study published in the Journal of the National Cancer Institute...
Blood Clot Prevention In A Dietary Supplement
5/10/2012
A compound called rutin, commonly found in fruits and vegetables and sold over the counter as a dietary supplement, has been shown to inhibit the formation of blood clots in an animal model of thrombosis...
Mobilizing T-Cells To Kill Cancer Cells
5/09/2012
The medical journal Nature Medicine reports that Immunocore Limited has developed a revolutionary cancer-targeting technology that involves new reagents known as ImmTACs (Immune Mobilising mTCR against Cancer), which mobilize T-cells that kill cancer cells and overcome immune tolerance to cancer...
Locating Rare Pancreatic Tumors With New Imaging Technique
5/09/2012
A non-invasive way to detect the exact location of very small life-threatening tumors in the pancreas (insulinomas) has been discovered by a team of researchers in Switzerland. This new technique will help surgeons to successfully remove the tumors that can be less than 1 centimeter in diameter...
Infection Behind One Sixth Of Cancers Worldwide
5/09/2012
Around 2 million, or one sixth of new cancer cases worldwide are due to infections that are largely preventable or treatable, says a landmark study published in The Lancet Oncology this week. Infections with certain bacteria, viruses and parasites have already been cited as strong risk factors for specific cancers, write the authors in their background information...
Researchers studying the molecular signals that drive a specific type of lymphoma have discovered a key biological pathway leading to this type of cancer. Cancerous cells have been described as being "addicted" to certain oncogenes (cancer-causing genes), and the new research may lay the groundwork for breaking that addiction and effectively treating aggressive types of B cell lymphoma...
