FGFR1 amplification predicts poor outcome in early-stage NSCLC

Amplification of fibroblast growth factor receptor 1 is associated with poor clinical outcome in patients with early-stage non-small-cell lung cancer, Swiss researchers report.

SCLC tumours replicated in mice from patients' CTCs

Scientists have used circulating tumour cells taken from patients with small-cell lung cancer to grow explant tumours in mice that retain the original’s morphological and genetic characteristics.

Greenlander study identifies single mutation with large diabetes risk

Researchers have used a Greenlandic cohort to identify a genetic mutation whose effect on the risk of diabetes is “several times larger” than any previously discovered.

Telephone-based weight loss intervention is effective in breast cancer treatments

A series of simple telephone calls can make a profound difference in helping women to meet their treatment goals for breast cancer, according to a randomized trial of women who are also obese, published online today in Journal of Clinical Oncology by Dr. Pamela Goodwin of Mount Sinai Hospital and the Lunenfeld-Tanenbaum Research Institute.

EU-funded projects in Romania retain young research talent

EU-funded research projects in Romania are helping the country retain talent. Young researchers, who might be tempted to look for a career abroad, find they can contribute at an even higher level by staying at home and participating in exciting projects.

Alternative disposal process in optic nerve cells has implications for neurodegenerative diseases

Biologists have long considered cells to function like self-cleaning ovens, chewing up and recycling their own worn out parts as needed.

Researchers explore genetic and cellular mechanisms of retinal development

The circuitry of the central nervous system is immensely complex and, as a result, sometimes confounding. When scientists conduct research to unravel the inner workings at a cellular level, they are sometimes surprised by what they find.

Researchers review effectiveness of RDTs in diagnosing visceral leishmaniasis

Researchers from the Cochrane Infectious Disease Group, co-ordinated through the editorial base in LSTM, conducted an independent review into the effectiveness of rapid diagnostic tests in diagnosing patients with visceral leishmaniasis (VL), published in The Cochrane Library today.

UCLA study sheds light on the development of lung cancer

UCLA researchers led by Dr. Brigitte Gomperts have discovered the inner workings of the process thought to be the first stage in the development of lung cancer. Their study explains how factors that regulate the growth of adult stem cells that repair tissue in the lungs can lead to the formation of precancerous lesions.

HIV infection emerges among PWID in the Middle East and North Africa

HIV epidemics are emerging among people who inject drugs in several countries in the Middle East and North Africa. Though HIV infection levels were historically very low in the Middle East and North Africa, substantial levels of HIV transmission and emerging HIV epidemics have been documented among people who inject drugs in at least one-third of the countries of this region, according to findings published today in PLOS Medicine.

Research reveals key aspect of protein regulation in cells

St. Jude Children's Research Hospital scientists have discovered how an important "on" switch is attached to the machinery that cells rely on to adapt thousands of proteins to meet changing conditions.

Researchers discover analgesic mechanism that prevents pain in Buruli ulcer patients

When the body receives an injury to the skin, a signal is sent to the brain, which generates a sensation of pain.

FAK inhibitors prevent ovarian cancer progression

A team of scientists, led by principal investigator David D. Schlaepfer, PhD, professor in the Department of Reproductive Medicine at the University of California, San Diego School of Medicine report that small molecule inhibitors to a protein called focal adhesion kinase (FAK) selectively prevent the growth of ovarian cancer cells as tumor spheroids.

Researchers explore how neurons establish spatial polarity and direction in tissues, organs

The question of how neurons and their axons establish spatial polarity and direction in tissues and organs is a fundamental question of any organism or biological system.

Researchers develop tissue engineered bone grafts for healing large bone defects

Bone is one of the most frequently transplanted tissues. And the demand is rising. Transplants treat large defects like those caused by trauma, complicated fractures, tumour resection or osteoporosis.

NIH receives $10 million grant for research on breast cancer metastasis

The American Cancer Society predicts that 40,000 American women will die from breast cancer this year. Most of those deaths will occur due to cells from the primary tumor that spread to other parts of the body-the process known as metastasis.

New model for HIV-1 infection offers promising option for clinical research

HIV-1, the virus responsible for most cases of AIDS, is a very selective virus. It does not readily infect species other than its usual hosts — humans and chimpanzees.

Osteoarthritis may be treated with stem cell mobilization therapy

Researchers in Taiwan have found that peripheral blood stem cells can be "mobilized" by injection of a special preparation of granulocyte colony-stimulating factor (G-CSF) into rats that modeled osteoarthritis (OA).

Yap1 oncogene drives recurrence and progression of pancreatic cancer

Pancreatic cancer tumors addicted to mutant Kras signaling for their growth and progression have a ready-made substitute to tap if they're ever forced to go cold-turkey on the mutant oncogene, scientists at The University of Texas MD Anderson Cancer Center report in the journal Cell.

Scientists create bone material from human stem cells to improve patient's welfare

Bone defects, like a damaged femoral head, are usually replaced by metal implants. This has many disadvantages, but now scientists in Germany have created bone material from human stem cells that could bring significant improvement to the patient's welfare.
