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.

Subtle epigenetic change plays important role in correct segregation of chromosomes

Abnormal number of chromosomes is often associated with cancer development. In a new study published in the journal Nature Structural and Molecular Biology researchers at Karolinska Institutet in Sweden have shown that a subtle epigenetic change plays an important role in the correct segregation of chromosomes.

Researchers discover promising new approach for leukemia treatment

A group of researchers at the Institute for Research in Immunology and Cancer of Universit- de Montr-al discovered a promising new approach to treating leukemia by disarming a gene that is responsible for tumor progression. That gene, known as Brg1 is a key regulator of leukemia stem cells that are the root cause of the disease, resistance to treatment and relapse.

Researchers identify histone proteins that may be key to generate induced totipotent stem cells

One major challenge in stem cell research has been to reprogram differentiated cells to a totipotent state. Researchers from RIKEN in Japan have identified a duo of histone proteins that dramatically enhance the generation of induced pluripotent stem cells (iPS cells) and may be the key to generating induced totipotent stem cells.

Researcher receives 2014 Japan Prize in Life Sciences for extraordinary work in the field of epigenetics

C. David Allis, a pioneer in the field of epigenetics whose discovery that chemical modifications of DNA-packaging proteins play a key role in regulating the activity of individual genes, will be awarded the 2014 Japan Prize in Life Sciences. The announcement, by the Japan Prize Foundation, was made at a press conference in Tokyo this morning.
