Study looks at rapid-onset dystonia-parkinsonism that has no known treatment

Fewer than 100 people in the world are known to be affected by a movement disorder called rapid-onset dystonia-parkinsonism (RDP), but its symptoms are life-changing. Seemingly normal young people are suddenly and dramatically unable to control movement of their arms or legs and have trouble speaking or swallowing. A normal life is nearly impossible.

Type 2 diabetes may be derived from composition of specific intestinal flora

Whether you have an increased risk of developing type 2 diabetes, in the future may be derived from the composition of your intestinal flora. That according to new metagenomics research of an international consortium of scientists, including Jeroen Raes, connected to VIB and Vrije Universiteit Brussel. Metagenomics is the study of the genetic material of complete ecosystems, in this case the human intestine. This study appears in the leading journal Nature.

DNp63a protein employs epigenetics to keep cancer cells alive

Squamous cell carcinoma (SCC) is diagnosed in about 700,000 people in the United States every year. Commonly contributing to SCC is a protein called DNp63a - it goes abnormally high and the ability of a patient's body to kill cancer cells goes abnormally low. In many cases of SCC, it's just that simple. And science thought the function of DNp63a was simple, as well: the tumor suppressor gene p53 is responsible for recognizing and killing cancer cells, and in SCC, it's usually inactivated. It looked like high DNp63a repressed p53, made SCC.

Scientists discover 12 genetic markers for ED in prostate cancer patients after radiotherapy

In the first study of its kind, a research team led by Mount Sinai School of Medicine and Albert Einstein College of Medicine of Yeshiva University discovered 12 genetic markers associated with the development of erectile dysfunction (ED) in prostate cancer patients who were treated with radiation.

MicroRNA processing in fat tissue plays a major role in aging and stress resistance

As part of their ongoing research investigating the biology of aging, the greatest risk factor for type 2 diabetes and other serious diseases, scientists at Joslin Diabetes Center have identified a new factor - microRNA processing in fat tissue - which plays a major role in aging and stress resistance.

KSU creates simple blood test that can accurately detect lung and breast cancer’s early stages

Researchers at Kansas State University have developed a simple blood test that can accurately detect the beginning stages of cancer.

Study characterizes movement of rhodopsin

A recent study in The Journal of General Physiology characterizes the movement of rhodopsin, a GPCR and member of a large family of transmembrane receptors responsible for many cellular responses and involved in many human diseases.

Karolinska Institutet scientists discover new approach to treat type II diabetes

An international team of scientists, led from Karolinska Institutet in Sweden, have discovered an entirely new approach to the treatment of type II diabetes. The therapy involves the blockade of signalling by a protein known as VEGF-B and this prevents fat from accumulating in the 'wrong' places, such as in muscles and in the heart. As a result the cells within these tissues are once again able to respond to insulin.

New understanding about functionality of CFTR protein

CFTR is an important protein that, when mutated, causes the life-threatening genetic disease cystic fibrosis. A study in The Journal of General Physiology (JGP) details how an accidental discovery has provided new understanding about CFTR functionality.

Study elucidates memory-forming signal transmission in the hippocampus

The hippocampus represents an important brain structure for learning. Scientists at the Max Planck Institute of Psychiatry in Munich discovered how it filters electrical neuronal signals through an input and output control, thus regulating learning and memory processes.

NCI-funded sequencing project aims to identify genetic links to colorectal cancer

Uncovering colon cancer's genetic roots is the focus of a new $13 million, four-year, National Cancer Institute-funded project at Fred Hutchinson Cancer Research Center. Ulrike (Riki) Peters, Ph.D., M.P.H., a member of the Hutchinson Center's Public Health Sciences Division, will lead the effort. She and her colleagues will use next-generation sequencing, a technique that captures entire genome sequences, to identify genetic links to colorectal cancer.

Adult stem cells can prevent Alzheimer's disease

In the first study of its kind, researchers at Korea's leading university and the RNL Bio Stem Cell Technology Institute announced this week the results of a study that suggests an astounding possibility: adult stem cells may not only have a positive effect on those suffering from Alzheimer's disease, they can prevent the disease.

CSL develops new drug candidate against type 2 diabetes

CSL Limited has developed a new drug candidate that is able to prevent the development of type 2 diabetes and reverse its progression in animal models of the disease.

Researchers characterize brain's immune response to infiltrating metastases

Brain metastases are common secondary complications of other types of cancer, particularly lung, breast and skin cancer. The body's own immune response in the brain is rendered powerless in the fight against these metastases by inflammatory reactions. Researchers at the MedUni Vienna have now, for the first time, precisely characterised the brain's immune response to infiltrating metastases. This could pave the way to the development of new, less aggressive treatment options.

Cell Banker 3 cryopreservation solution effectively preserves iPSCs

In a study to determine the best cryopreservation (freezing) solution to maintain induced pluripotent stem (iPS) cells, a team of researchers from Japan compared 12 kinds of commercially prepared and readily available cryopreservation solutions and found that "Cell Banker 3" out-performed the other 11 solutions by allowing iPS cells to be preserved for a year at -80 degrees C in an undifferentiated state.

Geographic information system software offers new way to study human remains

A common type of geographic mapping software offers a new way to study human remains. In a recent issue of the American Journal of Physical Anthropology, researchers describe how they used commercially available mapping software to identify features inside a human foot bone - a new way to study human skeletal variation.

New cervical cancer screening test introduced in El Salvador

"A new way to screen poor women for cervical cancer was introduced this month in El Salvador, using a test that was originally developed in China," the New York Times reports.

Researchers identify mechanism that appears to underlie non-familial form of Parkinson's

Researchers in the Taub Institute at Columbia University Medical Center (CUMC) have identified a mechanism that appears to underlie the common sporadic (non-familial) form of Parkinson's disease, the progressive movement disorder.

New technique can manipulate and measure magnetic particles without contact

If you throw a ball underwater, you'll find that the smaller it is, the faster it moves: A larger cross-section greatly increases the water's resistance. Now, a team of MIT researchers has figured out a way to use this basic principle, on a microscopic scale, to carry out biomedical tests that could eventually lead to fast, compact and versatile medical-testing devices.
