Combination of MEK inhibitors and nilotinib can overcome CML resistance to targeted drug

Cancer Research UK-funded scientists at The Institute of Cancer Research (ICR) have revealed a technique to kill chronic myeloid leukaemia (CML) cells that have stopped responding to a targeted drug, according to research published in Cancer Cell today.

High gut flora protects children against allergies

High diversity and a variety of bacteria in the gut protect children against allergies as opposed to some individual bacterial genera. These are the findings of a comprehensive study of intestinal microflora (gut flora) in allergic and healthy children, which was conducted at Linköping University in Sweden.

Scientists discover mechanism that controls 'fat switch' in the body

Scientists at Warwick Medical School have made an important discovery about the mechanism controlling the body's 'fat switch', shedding new light on our understanding of how proteins regulate appetite control and insulin secretion.

Toxins in Danish mushroom are effective against cancer cells

Researchers at the University of Copenhagen have explored the active principles of a Danish mushroom and found that some of the substances it contains are particularly toxic towards cancer cells. The goal is to synthesise and refine substances in the mushroom that may be useful in future drug development.

Clues to underlying causes of atherosclerosis

By changing the behavior of certain cells within human blood vessels, Cornell University researchers have discovered important clues as to the underlying causes of atherosclerosis - a discovery researchers hope can lead to more targeted drug therapies for the prevention of the disease.

Study identifies tertiary treatment as an important source of antibiotic resistant genes

Water discharged into lakes and rivers from municipal sewage treatment plants may contain significant concentrations of the genes that make bacteria antibiotic-resistant. That's the conclusion of a new study on a sewage treatment plant on Lake Superior in the Duluth, Minn., harbor that appears in ACS' journal Environmental Science & Technology.

Zoledronic acid increases bone mineral density, reduces recurrence in postmenopausal breast cancer

The addition of zoledronic acid to adjuvant endocrine therapy increased bone mineral density and reduced the risk for disease recurrence among postmenopausal women with early hormone receptor-positive breast cancer, according to new data from the ZO-FAST trial.

Considering varying extent to which genes are turned on or off can help develop personalised, predictive medicines

The vast majority of genetic disorders (schizophrenia or breast cancer, for example) have different effects in different people. Moreover, an individual carrying certain mutations can develop a disease, whereas another one with the same mutations may not. This holds true even when comparing two identical twins who have identical genomes. But why does the same mutation have different effects in different individuals?

H. pylori bacterium produces urease to neutralize gastric acid

A research team led by scientists at the Chinese University of Hong Kong is releasing study results this week showing how a bacterium, Helicobacter pylori, that causes more than half of peptic ulcers worldwide and that has been implicated in stomach cancer has managed for eons to turn the acidic environment of the human gut into one in which it can thrive.

Federal officials push greater medical use of gene sequencing

Almost a year after researchers in Wisconsin published a groundbreaking paper describing their use of genetic sequencing to diagnose and treat a 4-year-old boy, a national health agency is shifting its focus to put $416 million into making the secrets of our genetic script part of standard medical practice.

MS may progress from outermost layers of brain to its deep parts

Multiple sclerosis (MS) may progress from the outermost layers of the brain to its deep parts, and isn't always an "inside-out" process as previously thought, reported a new collaborative study from researchers at the Mayo Clinic and the Cleveland Clinic.

Viewpoints: Insurance safety net; Orszag on shift in health plans

In this country, three subjects that are guaranteed to generate a heated debate are religion, politics and, you guessed it, health insurance. Of the first two, Mark Twain observed that "people's beliefs and convictions are in almost every case gotten at second-hand."

New gene editing technique can heal sickle cell patients with their own cells

Researchers at the Salk Institute for Biological Studies have developed a way to use patients' own cells to potentially cure sickle cell disease and many other disorders caused by mutations in a gene that helps produce blood hemoglobin.

Treating 'brain tsunamis' could stop many victims of major head injury from further damage

Treating 'brain tsunamis' or 'killer waves' could stop many victims of major head injury from suffering additional brain damage, a study published in Lancet Neurology has found.

Researchers determine planar nets to build self-assembling 3-D structures

Material chemists and engineers would love to figure out how to create self-assembling shells, containers or structures that could be used as tiny drug-carrying containers or to build 3-D sensors and electronic devices.

Animal study offers insights into possible drug targets to improve memory as we age

Drugs that affect the levels of an important brain protein involved in learning and memory reverse cellular changes in the brain seen during aging, according to an animal study in the December 7 issue of The Journal of Neuroscience. The findings could one day aid in the development of new drugs that enhance cognitive function in older adults.

Massive and consistent changes in inflammatory gene expression seen in trauma, burns

Serious traumatic injuries, including major burns, set off a "genomic storm" in human immune cells, altering around 80 percent of the cells' normal gene expression patterns. In a report to appear in the December Journal of Experimental Medicine, members of a nationwide research collaborative describe the initial results of their investigation into the immune system response to serious injury, findings which have overturned some longstanding assumptions.
