Insulin resistance associated with cortical atrophy and brain dysfunction

Many complications of diabetes, including kidney disease, foot problems and vision problems are generally well recognized. But the disease's impact on the brain is often overlooked.

Johns Hopkins researchers unravel how breast cancer metastasizes

The spread of breast cancer is responsible for more than 90 percent of breast cancer deaths. Now, the process by which it spreads—or metastasizes—has been unraveled by researchers at Johns Hopkins. Reporting in two papers, the researchers have discovered the switch that enables breast cancer cells to travel to and be received in the lungs.

Viagra may improve antitumor immunity in people with melanoma

At first it sounds like good news: The body's own immune system gets active in almost every cancer - however, not necessarily for the benefit of the patient. "We distinguish between two different types of immune response," says Professor Dr. Viktor Umansky, immunologist at DKFZ and University Medical Center Mannheim. "On the one hand, cells of the immune system specifically attack tumor cells.

Prenatal processes gone awry linked to children with autism

A study by researchers at the University of California, San Diego Autism Center of Excellence shows that brain overgrowth in boys with autism involves an abnormal, excess number of neurons in areas of the brain associated with social, communication and cognitive development.

Potential fish enzyme biomarker for environmental toxins

The level of the enzyme carbonyl reductase (CBR) is elevated in the livers of fish that have been exposed to cleaned wastewater. Scientists at the University of Gothenburg can show that CBR has properties that may make it suitable to be used as a biomarker, an early warning signal of environmental toxins. The aim of the project is to achieve better environmental monitoring.

'Second hit' determines immune response against developing Burkitt's lymphoma

The human c-myc gene encodes a transcription factor (MYC) involved in the regulation of a vast number of other genes - it has been estimated that the transcription of about one in six genes is somehow under the control of MYC.

Study: Genes that are active in brain are transcribed with special mechanism

Knowledge about the development of the nervous system is of the greatest importance for us to understand the function of the brain and brain disorders. Researchers at Uppsala University have examined the key step when genes are read and found that genes that are active in the brain are transcribed with a special mechanism.

Prefrontal cortex neurons from individuals with autism show changes in chromatin structures

Neurons in the prefrontal cortex of individuals with autism show changes at numerous sites across the genome, according to a study being published Online First by the Archives of General Psychiatry, one of the JAMA/Archives journals.

TWIST protein plays a major role in controlling estrogen resistance in breast cancer

In dozens of experiments in mice and in human cancer cells, a team of Johns Hopkins scientists has closely tied production of a cancer-causing protein called TWIST to the development of estrogen resistance in women with breast cancer.

Polystyrene surface triples number of human ES and iPS cells in culture

By irradiating typical polystyrene lab plates with ultraviolet (UV) waves, Whitehead Institute and MIT scientists have created a surface capable of tripling the number of human embryonic stem (ES) and induced pluripotent stem (iPS) cells that can be grown in culture by current methods. Use of this novel surface also eliminates the need for layers of mouse "feeder cells" to support ES- and iPS-cell growth.
