Mouse model tests health risks of circadian disturbances
People who work outside of the normal 9-5 schedule or experience frequent jet lag have been found to be at an increased risk for everything from weight gain to cancer, but there are too many variables involved to conduct multi-decade, controlled studies in humans to confirm whether sleep pattern disruption is a correlation or the cause. In Current Biology, researchers present the next best thing: a model that subjects mice to human-relevant circadian rhythm disturbances.

Patients' own genetically altered immune cells show promise in fighting blood cancer
In recent years, immunotherapy has emerged as a promising treatment for certain cancers. Now this strategy, which uses patients' own immune cells, genetically engineered to target tumors, has shown significant success against multiple myeloma, a cancer of the plasma cells that is largely incurable. The results appeared in a study published online today in Nature Medicine.

'Pill on a string' could help spot early signs of cancer of the gullet
A 'pill on a string' developed by researchers at the University of Cambridge could help doctors detect esophageal cancer -- cancer of the gullet -- at an early stage, helping them overcome the problem of wide variation between biopsies, suggests research published today in the journal Nature Genetics.

Study shows promise of precision medicine for most common type of lymphoma
A clinical trial has shown that patients with a specific molecular subtype of diffuse large B-cell lymphoma are more likely to respond to the drug ibrutinib (Imbruvica) than patients with another molecular subtype of the disease. The study appeared online July 20, 2015, in Nature Medicine.

T-cell receptor therapy achieves encouraging clinical responses in multiple myeloma
Results from a clinical trial investigating a new T cell receptor therapy that uses a person's own immune system to recognize and destroy cancer cells demonstrated a clinical response in 80 percent of multiple myeloma patients with advanced disease after undergoing autologous stem cell transplants.

Researchers discover a possible reason for drug resistance in breast tumors
Amplified levels of HER2 membrane proteins drive unrestricted cell growth in certain types of breast cancer. HER2-tailored antibody-based therapeutics aim to prevent cancer cell growth. However, two-thirds of the patients develop resistance against such therapeutics. Why, is not yet understood. Researchers now found out that HER2 dimers appeared to be absent from a small sub-population of resting SKBR3 breast cancer cells. This subpopulation may have self-renewing properties and thus may be resistant to antibody therapy.

Imaging glucose uptake activity inside single cells
Researchers at Columbia University have reported a new approach to visualize glucose uptake activity in single living cells by light microscopy with minimum disturbance. In a recent study published in Angewandte Chemie International Edition, Associate Professor of Chemistry Wei Min's team developed a new glucose analogue that can mimic the natural glucose, and imaged its uptake as energy source by living cancer cells, neurons and tissues at the single cell level.

Exercising 300 minutes per week better for reducing total fat in postmenopausal women
Postmenopausal women who exercised 300 minutes per week were better at reducing total fat and other adiposity measures, especially obese women, during a one-year clinical trial, a noteworthy finding because body fat has been associated with increased risk of postmenopausal breast cancer, according to an article published online by JAMA Oncology.

Resveratrol, quercetin could provide new options for cancer therapy
Resveratrol and quercetin, two polyphenols that have been widely studied for their health properties, may soon become the basis of an important new advance in cancer treatment, primarily by improving the efficacy and potential use of an existing chemotherapeutic cancer drug. For the first time a system has been developed that could dramatically increase the levels of these compounds in the body.

30-year study shows that moderate hormone suppression may be enough in thyroid cancer
A study of long-term thyroid cancer outcomes shows, among other findings, that moderate suppression of thyroid-stimulating hormone, which drives the disease, may be as beneficial as more extreme hormone suppression. Extreme TSH suppression is associated with increased side effects including osteoporosis and heart rhythm irregularities. Results are published online ahead of print in the journal Thyroid.

Magnetic nanoparticles could be key to effective immunotherapy
In recent years, researchers have hotly pursued immunotherapy, a promising form of treatment that relies on harnessing and training the body's own immune system to better fight cancer and infection. Now, results of a study led by Johns Hopkins investigators suggests that a device composed of a magnetic column paired with custom-made magnetic nanoparticles may hold a key to bringing immunotherapy into widespread and successful clinical use.

A portable 'paper machine' can diagnose disease for less than $2
In the US and other industrialized nations, testing for infectious diseases and cancer often requires expensive equipment and highly trained specialists. In countries where resources are limited, performing the same diagnostics is far more challenging. To address this disparity, scientists are developing a portable, low-cost 'paper machine' for point-of-care detection of infectious diseases, genetic conditions and cancer. Their report appears in the ACS journal Analytical Chemistry.
