Scientists shed new light on why pancreatic cancer drugs can fail

Cancer Research UK scientists led an international team of investigators who have discovered a new mechanism that may explain why pancreatic cancer patients are often resistant to a common chemotherapy treatment called gemcitabine, according to a study published in Science.

Tamed virus wipes out cancer safely

Cancer Research UK scientists have tamed a virus so that it attacks and destroys cancer cells but does not harm healthy cells, according to a paper published in PLoS Pathogens, today.

Cancer drugs erlotinib and gefitinib might treat alcoholism

A class of drugs already approved as cancer treatments might also help to beat alcohol addiction. That's the conclusion of a discovery in flies of a gene, dubbed happyhour, that has an important and previously unknown role in controlling the insects' response to alcohol.

Simple genetic test determines transplant drug tolerance

A simple genetic test can determine a kidney transplant patient's tolerance for a potent anti-rejection medication, according to an upcoming study in the Journal of the American Society Nephrology (JASN). The test could allow doctors to individualize each patient's dose, optimizing the drug's benefits and minimizing its side effects.

Research looks at ways to reduce the over-prescribing of antibiotics

Improving communications skills and the use of a simple blood test could help cut the growing number of inappropriate prescriptions of antibiotics, a joint Cardiff University trial has discovered.

New direction needed for obesity research

Most of the current obesity research is not proving helpful in finding solutions to the growing international epidemic, according to a Deakin University public health expert.

Genetic testing for breast or ovarian cancer risk may be greatly underutilized

Although a test for gene mutations known to significantly increase the risk of hereditary breast or ovarian cancer has been available for more than a decade, a new study finds that few women with family histories of these cancers are even discussing genetic testing with their physicians or other health care providers.

Researchers discuss combined approach to maximize benefits and minimize risks of stem cell therapy

Once placed into a patient's body, stem cells intended to treat or cure a disease could end up wreaking havoc simply because they are no longer under the control of the clinician.

Research details function of key protein in cancer spread

Research led by David Worthylake, PhD, Assistant Professor of Biochemistry and Molecular Biology at LSU Health Sciences Center New Orleans, may help lay the groundwork for the development of a compound to prevent the spread of cancer. The research will be published in the May 29, 2009 issue of the Journal of Biological Chemistry.

Protein discovery provides new targets for drugs that could extend the healthy years of life

A protein that plays a key role in tumor formation, oxygen metabolism and inflammation is involved in a pathway that extends lifespan by dietary restriction.

Research suggests role of low vitamin D in cancer

In studying the preventive effects of vitamin D, researchers at the Moores Cancer Center at the University of California, San Diego, have proposed a new model of cancer development that hinges on a loss of cancer cells' ability to stick together. The model, dubbed DINOMIT, differs substantially from the current model of cancer development, which suggests genetic mutations as the earliest driving forces behind cancer.

Novel method stimulates growth of new neurons in adult brain

University at Buffalo researchers have identified a new mechanism that plays a central role in adult brain stem cell development and prompts brain stem cells to differentiate into neurons.

Study offers new insights into morphine-induced tolerance and increased pain sensitivity

A study published in the June issue of Anesthesiology has shown that a drug metabolite of the opioid morphine may be a key factor in the paradoxical increased sensitivity to pain caused by chronic morphine use. For the first time, this metabolite (called morphine-6 glucuronide, or M6G) was shown to act independently of the pain receptors typically targeted during morphine administration.

Vitamin D found in fish improves cognitive function

Eating fish - long considered 'brain food' - may really be good for the old grey matter, as is a healthy dose of sunshine, new research suggests.

A new slow-release hydrogen sulfide donating molecule may hold the key to the development of new anti-inflammatory drugs

Researchers from the Peninsula Medical School in Exeter have synthesized a new molecule which releases hydrogen sulfide (H2S) - the gas that gives rotten eggs their characteristic smell and which has recently been found to be produced naturally in the body - and discovered that it could in time lead to a range of new, safer and effective anti-inflammatory drugs for human use.

People with Down syndrome may have more cancer-protective genes

Most cancers are rare in people with Down syndrome, whose overall cancer mortality is below 10 percent of that in the general population. Since they have an extra copy of chromosome 21, it's been proposed that people with Down syndrome may be getting an extra dose of one or more cancer-protective genes.

Junk DNA may not be so ‘junky’ after all

Scientists have called it "junk DNA." They have long been perplexed by these extensive strands of genetic material that dominate the genome but seem to lack specific functions. Why would nature force the genome to carry so much excess baggage?

Twins born after fertility treatment have a higher risk of problems at birth and in the first three years of life

Twins born as a result of assisted reproductive technology (ART) are more likely to be admitted to neonatal intensive care and to be hospitalised in their first three years of life than spontaneously conceived twins, according to new research published online today (Wednesday 20 May) in Europe’s leading reproductive medicine journal Human Reproduction.
