Loss of IGSF1 gene function causes central hypothyroidism

Loss of function in the X-linked immunoglobulin superfamily member 1 (IGSF1) gene causes central hypothyroidism, testicular enlargement, and variable prolactin deficiency, according to data presented at the 82nd Annual Meeting of the American Thyroid Association in Québec City, Québec, Canada.

Caltech biologists gain new insight into migrating cells

At any given moment, millions of cells are on the move in the human body, typically on their way to aid in immune response, make repairs, or provide some other benefit to the structures around them. When the migration process goes wrong, however, the results can include tumor formation and metastatic cancer. Little has been known about how cell migration actually works, but now, with the help of some tiny worms, researchers at the California Institute of Technology (Caltech) have gained new insight into this highly complex task.

Iron transport may contribute to diabetes

Scientists have been trying to explain the causes of diabetes for many years. Researchers at the University of Copenhagen and Novo Nordisk A/S have now shown that the increased activity of one particular iron-transport protein destroys insulin-producing beta cells. In addition, the new research shows that mice without this iron transporter are protected against developing diabetes.

Study identifies factors that contribute to solid stress within tumors

It's a high-pressure environment within solid tumors. Abnormal blood and lymphatic vessels cause fluids to accumulate, and the uncontrolled proliferation of cancer cells within limited space leads to the buildup of what is called solid stress.

First extensive analysis of Allen Human Brain Atlas

Scientists at the Allen Institute for Brain Science reported in the latest issue of the journal Nature that human brains share a consistent genetic blueprint and possess enormous biochemical complexity. The findings stem from the first deep and large-scale analysis of the vast data set publicly available in the Allen Human Brain Atlas.

Researchers develop cranial neural crest cell lines

Researchers have successfully developed a stable population of neural crest cells derived from mice that can be grown in large quantities in the laboratory and that demonstrates the potential to develop into many different cell types needed throughout the body.

Researchers use nanoparticles to deliver drugs to mitochondria within cells

Nanoparticles have shown great promise in the targeted delivery of drugs to cells, but researchers at the University of Georgia have refined the drug delivery process further by using nanoparticles to deliver drugs to a specific organelle within cells.

MiR-34a plays a key role in obesity

Scientists have identified a key molecular player in a chain of events in the body that can lead to fatty liver disease, Type II diabetes and other metabolic abnormalities associated with obesity. By blocking this molecule, the researchers were able to reverse some of the pathology it caused in obese mice.

PNAS: Ras proteins bring tension to the phosphate chain

Proteins accelerate certain chemical reactions in cells by several orders of magnitude. The molecular mechanism by which the Ras protein accelerates the cleavage of the molecule GTP and thus slows cell growth is described by biophysicists at the Ruhr-Universit-t Bochum led by Prof. Dr. Klaus Gerwert in the Online Early Edition of the journal PNAS.

Adults with autism have unreliable neural sensory responses to visual, auditory and touch

Autistic adults have unreliable neural sensory responses to visual, auditory, and touch stimuli, according to research published in the journal Neuron. This poor response reliability, the study's authors conclude, appears to be a fundamental neural characteristic of autism.

Tel Aviv University researcher discovers homing device that draws cancer

The process of metastasis, by which cancer cells travel from a tumor site and proliferate at other sites in the body, is a serious threat to cancer patients. According to the National Cancer Institute, most recurrences of cancer are metastases rather than "new" cancers.
