Study defines specific genetic mechanism that explains some of schizophrenia's heritability

The overall number and nature of mutations—rather than the presence of any single mutation—influences an individual's risk of developing schizophrenia, as well as its severity, according to a discovery by Columbia University Medical Center researchers published in the latest issue of Neuron.

TSRI researchers discover key proteins involved in one type of DNA repair gone awry

Accumulation of DNA damage can cause aggressive forms of cancer and accelerated aging, so the body's DNA repair mechanisms are normally key to good health. However, in some diseases the DNA repair machinery can become harmful.

3D shape of leukemia cell's genome holds key to solving puzzle of human diseases

To solve a puzzle, you need to recognize shapes, patterns and a particular kind of order. In much the same way, researchers at McGill University have discovered that the 3D shape of a leukemia cell's genome holds a key to solving the puzzle of human diseases. The researchers report their findings in the open access journal Genome Biology.

Scientists unlock one of mysteries of modern genetics

Scientists at Indiana University have unlocked one of the mysteries of modern genetics: how acquired traits can be passed between generations in a process called epigenetic inheritance. The new work finds that cells don't know to silence some genes based on information hardwired into their DNA sequences, but recognize heritable chemical marks that are added to the genes. These chemical tags serve as a form of molecular memory, allowing cells to recognize the genes and remember to silence them again in each new generation.

Researchers identify steps by which cell removes RNA from cytoplasm

RNA encodes the proteins that play a key role in cellular reproduction, but the manner in which cells regulate its removal once these proteins are synthesized remains a mystery. One piece of this mystery has been solved as researchers at the University of North Carolina at Chapel Hill who have identified the steps by which a cell removes RNA from the cytoplasm.

Researchers identify high-speed cellular transport mechanism

Our DNA and its architecture are duplicated every time our cells divide. Histone proteins are key building blocks of this architecture and contain crucial information that regulates our genes. Danish researchers show how an enzyme controls reliable and high-speed delivery of histones to DNA copying hubs in our cells. This shuttling mechanism is crucial to maintain normal function of our genes and prevent disease. The results are published in the journal Nature Communications.

Scientists uncover key mechanism of gene regulation

In the cells of humans and other organisms, only a subset of genes are active at any given time, depending largely on the stage of life and the particular duties of the cell. Cells use different molecular mechanisms to orchestrate the activation and deactivation of genes as needed.

Study identifies promising target for new drugs to treat lethal form of brain cancer

A molecule in cells that shuts down the expression of genes might be a promising target for new drugs designed to treat the most frequent and lethal form of brain cancer, according to a new study by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

Study identifies enzyme with key role in precancerous lesions

Cancer of the pancreas is usually not detected until it's too late to cure. But precursor lesions that form in the pancreas and its ducts can signal the disease before it strikes, and when caught early enough, they can be prevented from progressing to become cancer.

Researchers develop new technology that reveals secrets of cellular memory

Cells in our body are constantly dividing to maintain our body functions. At each division, our DNA code and a whole machinery of supporting components has to be faithfully duplicated to maintain the cell's memory of its own identity.
