Researchers discover role played by epigenetic factors in senescence and age-related diseases

One way cells promote tumor suppression is through a process called senescence, an irreversible arrest of proliferation. Senescence is thought to be associated with normal aging, but is also a protective measure by the body against run-away cell replication.

Trinity researchers reveal CHD5 protein acts as tumor suppressor in nervous system development

CHD5 has previously been proposed as a tumour suppressor, acting as a brake that prevents healthy cells from developing into cancer cells. But the part played by the protein in healthy tissue, and whether this role is important for its ability to counter tumour growth, has remained largely uncharted.

Scientists present novel method to visualize how nuclear protein mobility changes following DNA damage

Understanding the cellular response to DNA strand breaks is crucial to decipher the mechanisms maintaining the integrity of our genome. In eukaryotic cells, the molecular events triggered by DNA damage are strongly influenced by the local chromatin environment surrounding the lesion. The ensuing DNA repair process, in turn, impacts on chromatin structure. In order to understand how these two fundamental processes are mutually connected, both chromatin rearrangements induced by DNA damage as well as DNA repair activity have to be visualized in living cells.

High mobility group (HMG) genes and cancer: an interview with Dr. Linda Resar, Johns Hopkins University School of Medicine

High mobility group A genes are highly expressed in all aggressive cancers studied to date. These genes encode the high mobility group A (HMGA) proteins. In other words, these genes provide the genetic “code” necessary to produce HMGA proteins.

Cancer-linked mitosis: an interview with Professor Scott Kern, Johns Hopkins University School of Medicine

Mitosis is the process by which a cell gives rise to two daughter cells. It’s the basis behind the growth of the human body, the renewal of the human body as it ages, and unfortunately, the growth of cancers.

Statins: A class of cholesterol-lowering drugs may help treat Rett Syndrome

Statins, a class of cholesterol-lowering drugs found in millions of medicine cabinets, may help treat Rett Syndrome, according to a study published today in Nature Genetics. The Rett Syndrome Research Trust (RSRT) funded this work with generous support from the Rett Syndrome Research Trust UK and Rett Syndrome Research & Treatment Foundation.

Scientists focus on the role of mutated adult neural stem cells play in human diseases

CHARGE syndrome* is a severe developmental disorder affecting multiple organs. It affects 1 in 8500 newborns worldwide. The majority of patients carry a mutation in a gene called CHD7. How this single mutation leads to the broad spectrum of characteristic CHARGE symptoms has been a mystery.

Discovery sheds new light on aggressiveness of certain breast cancers

In a discovery that sheds new light on the aggressiveness of certain breast cancers, Whitehead Institute researchers have identified a transcription factor, known as ZEB1, that is capable of converting non-aggressive basal-type cancer cells into highly malignant, tumor-forming cancer stem cells (CSCs). Intriguingly, luminal breast cancer cells, which are associated with a much better clinical prognosis, carry this gene in a state in which it seems to be permanently shut down.

RORA: A novel candidate gene for autism regulates large number of other genes

A new study by Valerie Hu, Ph.D., professor of biochemistry and molecular medicine at the George Washington University (GW) School of Medicine and Health Sciences (SMHS), reports that RORA, a novel candidate gene for autism discovered by her group in a 2010 study, regulates a large number of other genes associated with autism.

PLK1 crucial for proper functioning of cancer cells, researchers reveal

One of the main indicators for determining the activity of a tumour or cancer is cell division. Cancer cells divide more than other types and the genes and molecules involved in the process of division are, often, targets for identifying and treating certain types of cancer.

Modifications in key epigenetic markers influence human embryonic stem cells

Scientists have long known that control mechanisms known collectively as "epigenetics" play a critical role in human development, but they did not know precisely how alterations in this extra layer of biochemical instructions in DNA contribute to development.
