Targeted therapeutics for colon cancer to be presented at AACR meeting
2012-04-04
(Press-News.org) (Boston) - Anurag Singh, PhD, assistant professor in the Department of Pharmacology and Experimental Therapeutics at Boston University School of Medicine has been invited to present his recent work on targeted therapeutics for colon cancer at the American Association of Cancer Research Annual Meeting in Chicago, IL. Singh's seminar, scheduled for Tuesday April 3rd, will be featured in the "Late-Breaking Abstracts Mini-Symposium". This highlights recent and provocative groundbreaking research in cancer biology.
Over one million cases of colon cancer are diagnosed worldwide each year resulting in approximately 600,000 deaths annually. Disease-causing mutations in the KRAS gene are found in over half of these cases. In the United States, colon cancer patients are routinely genotyped for KRAS gene mutations and those with mutations are excluded from receiving novel "targeted" therapeutic agents due to a lack of clinical benefit. Thus, patients with KRAS gene mutations are faced with very limited therapeutic options and are subsequently given very poor clinical prognoses.
Singh and his colleagues have identified a network of genes that are hyper-activated in KRAS mutant colon cancers. Within this network is a gene called MAP3K7 or TAK1, which plays a very critical role in promoting colon cancer disease progression. Pharmacological inhibition of TAK1 results in strong killing of affected tumor cells, with minimal effects in "normal" non-mutated cells. "These findings raise the possibility that anti-TAK1 agents could provide the basis for "personalized" medicine in patients with highly aggressive KRAS mutant colon cancers," said Singh. Efforts are now underway to identify clinically efficacious TAK1 inhibitors.

People who are excluded by others online, such as on Facebook, may feel just as bad as if they had been excluded in person, according to researchers at Penn State and Misericordia University.
"If you've ever felt bad about being 'ignored' on Facebook you're not alone," said Joshua Smyth, professor of biobehavioral health and of medicine at Penn State. "Facebook -- with its approximately 800 million users -- serves as a place to forge social connections; however, it is often a way to exclude others without the awkwardness of a face-to-face interaction. Most people would ...

Higher-spending hospitals do have better outcomes for their emergency patients, including fewer deaths, according to a Vanderbilt study released as a working paper through the National Bureau of Economic Research.
Vanderbilt's John Graves, Ph.D., assistant professor of Preventive Medicine, along with colleagues from the Massachusetts Institute of Technology and Cornell University, examined Medicare ambulance and hospital data from 2002-2008, finding that higher-cost hospitals have significantly lower one-year mortality rates compared to lower-cost hospitals.

Dr. Steve Hahn, Acworth prosthodontist, and his staff are pleased to announce the pending opening of a new location in Midtown, Atlanta. The new location will give Dr. Hahn and his associates access to a whole new group of patients.
Roughly 30 miles from the current Acworth location, the Midtown location will be able to bring dental services to a large population center in the heart of Atlanta. For patients of the Acworth dentist who may live closer to Midtown or are employed there, the new location offers a new level of convenience.
"We are all tremendously ...

CHICAGO, IL – April 3, 2012 – The brains of people with anorexia and obesity are wired differently, according to new research. Neuroscientists for the first time have found that how our brains respond to food differs across a spectrum of eating behaviors – from extreme overeating to food deprivation. This study is one of several new approaches to help better understand and ultimately treat eating disorders and obesity.
Eating disorders have the highest mortality rate of any mental illness. And more than two-thirds of the U.S. population are overweight or obese – a health ...

Scientists have long believed that vitamin D, which is naturally absorbed from sunlight, has an important role in the functioning of the body's autoimmune system. Now Prof. Howard Amital of Tel Aviv University's Sackler Faculty of Medicine and Sheba Medical Center has discovered that the vitamin may also affect the outcomes of patients in intensive care.
In a six-month study, Prof. Amital and his colleagues found that patients who had a vitamin D deficiency lived an average of 8.9 days less than those who were found to have sufficient vitamin D. Vitamin D levels also ...

High fat diets cause damage to blood vessels earlier than previously thought, and these structural and mechanical changes may be the first step in the development of high blood pressure. These findings in mice, by Marie Billaud and colleagues from the University of Virginia School of Medicine in the US, are published online in Springer's Journal of Cardiovascular Translational Research.
With age, increasing weight and metabolic disease, the internal walls of our large arteries progressively thicken and become less elastic, which can lead to furring up of the arteries ...

Children who grow up learning to speak two languages are better at switching between tasks than are children who learn to speak only one language, according to a study funded in part by the National Institutes of Health. However, the study also found that bilinguals are slower to acquire vocabulary than are monolinguals, because bilinguals must divide their time between two languages while monolinguals focus on only one.
In the study, bilingual and monolingual children were asked to press a computer key as they viewed a series of images -- either of animals or of depictions ...

In order to maintain healthy smiles, Dr. Chris Hooper, dentist in Virginia Beach, offers his patients extensive dental health care information around the clock. It is commonly understood that in order to avoid cavities and more serious dental problems, a person has to take good care of their teeth and Dr. Hooper of Gentle Dental Center helps reiterate this.
"Consistent brushing and flossing habits do more than just protect your oral health, they also help keep a host of other serious conditions at bay. Because of this I want to ensure that my patients fully understand ...

Montreal, April 3, 2012 — Love it or leave it — if only it were that simple. According to new research from Concordia University, the Université de Montréal and HEC Montréal, staying in an organization out of a sense of obligation or for lack of alternatives can lead to emotional exhaustion, a chronic state of physical and mental depletion resulting from continuous stress and excessive job demands.
Published in the journal Human Relations, the study found that people who stay in their organizations because they feel an obligation towards their employer are more likely ...
