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.

Low-grade inflammatory processes drive development of osteoarthritis

In a study to be published online Nov. 6 in Nature Medicine, investigators at the Stanford University School of Medicine have shown that the development of osteoarthritis is in great part driven by low-grade inflammatory processes.

Researchers match protein to the job it performs in human body

Scientists at Rochester Institute of Technology and Dowling College are engaged in a similar game with higher stakes. Instead of cards, they are matching the protein to the job it performs in the human body. Their research could lead to drugs that target proteins and switch on or off specific functions associated with various diseases.

Hirano bodies may play a protective role in progression of Alzheimer's

Hirano bodies are almost indescribably tiny objects found in nerve cells of people suffering from conditions such as Alzheimer's, mad cow and Lou Gehrig's diseases. Yet for decades, researchers weren't sure if these structures helped cause the conditions or appeared after onset of the disease and had some other role.

Epigenetic alterations may play an important role in autism

Scientists at the University of Massachusetts Medical School are the first to map epigenetic changes in neurons from the brains of individuals with autism, providing empirical evidence that epigenetic alterations-changes in gene expression caused by mechanisms other than changes in the underlying DNA sequence-may play an important role in the disease.

Study on epigentics and cellular memory

How do fetal cells know what cell types to become? Why do cells in the adult body sometimes forget what they are and develop into cancer cells? These are some of the questions intensively investigated within the research field of epigenetics.

First-ever Mantle Cell Lymphoma Symposium to be held on Nov. 12

The Lymphoma Division of the John Theurer Cancer Center at Hackensack University Medical Center with the participation from the Facebook groups "Hope for Lymphoma" and "Our MCL Family," will host its first-ever Mantle Cell Lymphoma Symposium on Saturday, November 12 from 8:30am - 3:45pm.

Connexin 36 protects mouse pancreatic beta-cells against immune molecules

Type 1 diabetes is a lifelong disease characterized by high levels of sugar (glucose) in the blood. It is caused by the patient's immune system attacking and destroying the cells in their pancreas that produce the hormone insulin, which regulates blood glucose levels. Surprisingly, little is known about the mechanisms regulating the sensitivity and resistance of these cells, which are known as beta-cells, to immune system attack.
