A simple blood test could be used to detect breast cancer

University of Leicester and Imperial College London in study to determine whether DNA in blood could show early signs of cancer

2012-10-02

(Press-News.org) A SIMPLE blood test could one day be a more accurate way to test for the early signs of breast cancer than using mammograms to spot a lump say researchers today (Tuesday), as Breast Cancer Awareness Month gets underway.

They also hope the blood test could improve treatment by detecting whether breast cancer patients are likely to relapse and what drugs their particular type of tumour will respond to.

This pioneering new clinical study – funded by Cancer Research UK in collaboration with the University of Leicester and Imperial College London – is about to start in the UK's largest breast screening clinic at Charing Cross Hospital, London.

Researchers will take blood samples from women attending the breast screening clinic and compare the DNA in the blood of women who are diagnosed with breast cancer with those that do not have cancer to see what DNA markers are consistent.

Dr Jacqui Shaw, principal investigator from the University of Leicester, said: "This exciting research means we could one day have a blood test that detects the very early signs of cancer meaning women could have an annual blood test rather than breast screening. This would remove any worry and anxiety for women who are called for further investigations after a mammogram only to find they don't have cancer.

"As things stand we aren't able to monitor breast cancer patients after they've had surgery and treatment - which is like treating diabetes but not measuring blood sugar levels. The new blood test could change that."

Professor Charles Coombes, co-investigator and Cancer Research UK's breast cancer expert from Imperial College, said: "This type of translational science is extremely promising and the international scientific community is collaborating on its development. When a woman has breast cancer we can tell by the DNA in their blood. But what we're trying to find out in our study is how early the signs of breast cancer show up in a blood test. So by looking at blood samples of women who have breast cancer diagnosed through screening we can see if the cancer is already showing in their blood.

"Our research team is only looking at breast cancer but there are a number of other projects that are looking at using a blood test to detect other cancers such as bowel and lung."

Kate Law, director of clinical research at Cancer Research UK, said: "We really do hope that in the not too distant future a simple blood test for breast cancer, which could not only detect cancer but help with treatment options, will become standard practice on the NHS.

"Cancer Research UK has invested over a million pounds into this project as this fascinating area of science could prove to be a huge step forward in the way certain types of cancer are diagnosed and treated."

Breakthrough in understanding lung cancer vulnerabilities points the way to new targeted therapy

2012-10-02

More effective treatments for one of the deadliest forms of cancer are one step closer thanks to groundbreaking research from an international collaborative study. Scientists from the Universities of Sheffield and Cologne have identified the dependencies of multiple Small Cell Lung Cancer (SCLC) types – paving the way for clinical trials of new targeted treatments which could revolutionise the current approach. Around 40,000 people are diagnosed annually with lung cancer in the UK, and SCLC accounts for nearly one in five of all these cases. Unfortunately, the prognosis ...

Severely obese are fastest growing group of overweight Americans, study finds

2012-10-02

The proportion of Americans who are severely obese -- those people 100 pounds or more overweight -- continues to increase rapidly and much faster than those with moderate obesity, but the rate of growth has slowed, according to a new RAND Corporation study. The RAND study found that from 2000 to 2010, the proportion of Americans who were severely obese rose from 3.9 percent of the population to 6.6 percent -- an increase of about 70 percent. The findings mean that more than 15 million adult Americans are morbidly obese with a body mass index of 40 or more. The good ...

Meeting pigs' phosphorous requirements with fermented soybean meal

2012-10-02

Fermented soybean meal (FSBM), considered a promising substitute for fish meal in weanling pig diets because of its protein content, lower cost, and lack of anti-nutritional factors, may have an additional advantage. University of Illinois researchers recently found that pigs digest the phosphorous in FSBM better than the phosphorus in conventional soybean meal. "Most of the P in soybean meal is bound to phytate, so it's not available to pigs," explained animal sciences professor Hans Stein. Previous research by Stein's group found that pigs digest the phosphorous in ...

Marine animals could hold the key to looking young

2012-10-02

Sea cucumbers and sea urchins are able to change the elasticity of collagen within their bodies, and could hold the key to maintaining a youthful appearance, according to scientists at Queen Mary, University of London. The researchers investigated the genes of marine creatures such as sea urchins and sea cucumbers, known as echinoderms. They found the genes for "messenger molecules" known as peptides, which are released by cells and tell other cells in their bodies what to do. The study was published online in the journals PLOS One and General and Comparative Endocrinology. ...

Climate change cripples forests

2012-10-02

LOS ALAMOS, N.M., Oct. 1, 2012— Combine the tree-ring growth record with historic information, climate records and computer-model projections of future climate trends, and you get a grim picture for the future of trees in the southwestern United States. That's the word from a team of scientists from Los Alamos National Laboratory, the U.S. Geological Survey, University of Arizona, and several other partner organizations. Described in a paper published in Nature Climate Change this week, "Temperature as a potent driver of regional forest drought stress and tree mortality," ...

No relief for relief workers: Humanitarian aid work raises risk of depression and anxiety

2012-10-02

Humanitarian workers are at significant risk for mental health problems, both in the field and after returning home. The good news is that there are steps that they and their employers can take to mitigate this risk. These findings, from a new study by scientists at the U.S. Centers for Disease Control and Prevention (CDC) and collaborators, including Columbia University's Mailman School of Public Health, are published online in the journal PLOS ONE. Researchers surveyed 212 international humanitarian workers at 19 NGOs. Prior to deployment, 3.8% reported symptoms of ...

Novel gene associated with Usher syndrome identified

2012-10-02

LEXINGTON, Ky. (Oct. 1, 2012) — Usher syndrome is a hereditary disease in which affected individuals lose both hearing and vision. The impact of Usher syndrome can be devastating. In the United States, approximately six in every 100,000 babies born have Usher syndrome. Several genes associated with different types of Usher syndrome have been identified. Most of these genes encode common structural and motor proteins that build sensory cells in the eye and inner ear. In a paper to be published in the November 2012 issue of Nature Genetics, a team of researchers from ...

Zinc deficiency mechanism linked to aging, multiple diseases

2012-10-02

CORVALLIS, Ore. – A new study has outlined for the first time a biological mechanism by which zinc deficiency can develop with age, leading to a decline of the immune system and increased inflammation associated with many health problems, including cancer, heart disease, autoimmune disease and diabetes. The research was done by scientists in the Linus Pauling Institute at Oregon State University and the OSU College of Public Health and Human Sciences. It suggests that it's especially important for elderly people to get adequate dietary intake of zinc, since they may need ...

Popular antidepressant might prevent heart failure

2012-10-02

ANN ARBOR—A medication usually used to help treat depression and anxiety disorders has the potential to help prevent heart failure, according to researchers at the University of Michigan. John Tesmer, research professor at the U-M Life Sciences Institute and professor in the Department of Pharmacology at the U-M Medical School, and his research team at the Tesmer lab found that paroxetine, a selective serotonin reuptake inhibitor (SSRI) sold under the name Paxil, inhibits G protein-coupled receptor kinase 2 (GRK2), a protein kinase that becomes over-expressed when people ...

Stem cells improve visual function in blind mice

2012-10-02

An experimental treatment for blindness, developed from a patient's skin cells, improved the vision of blind mice in a study conducted by Columbia ophthalmologists and stem cell researchers. The findings suggest that induced pluripotent stem (iPS) cells – which are derived from adult human skin cells but have embryonic properties – could soon be used to restore vision in people with macular degeneration and other diseases that affect the eye's retina. "With eye diseases, I think we're getting close to a scenario where a patient's own skin cells are used to replace retina ...
