Acetylation News and Research

RSS

Acetylation (or in IUPAC nomenclature ethanoylation) describes a reaction that introduces an acetyl functional group into an organic compound. Deacetylation is the removal of the acetyl group.

Researchers show how a cell surface protein can mobilize immune cells to attack malignant tumors

Revealing a biological combat strategy worthy of a five-star general, researchers from Houston Methodist Hospital, University of Chicago and Cornell University have shown how a cell surface receptor--a specialized protein which communicates signals between a cell and the outside world--can mobilize immune cells to attack, rather than protect, malignant tumors.

Penn Medicine researchers show that DNA editing errors can lead to cancer

Sometimes when the immune system makes small mistakes, the body amplifies its response in a big way: Editing errors in the DNA of developing T and B cells can cause blood cancers. Now, researchers from the Perelman School of Medicine, University of Pennsylvania have shown that when the enzyme key to cutting and pasting segments of DNA hits so-called "off-target" spots on a chromosome, the development of immune cells can lead to cancer in animal models.

Study reveals new epigenetic mechanism underlying progression of cancer tumors

Aggressive cancer growth and alterations in gene activity without changes in DNA sequence (epigenetics) are associated with mutant p53 proteins, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

Ancient natural compound can protect the heart from hypertrophy

A natural compound derived from the bark of the magnolia tree, can protect the heart from hypertrophy, a thickening of cardiac muscle often caused by chronic high blood pressure that can lead to heart failure, researchers report in the April 14 issue of the online journal Nature Communications.

IU researchers reveal how Toxoplasma parasites modify brain cells

Rodents infected with a common parasite lose their fear of cats, resulting in easy meals for the felines. Now IU School of Medicine researchers have identified a new way the parasite may modify brain cells, possibly helping explain changes in the behavior of mice -- and humans.

Researchers discover new way by which metabolism is linked to regulation of DNA

A research team at the Faculty of Medicine & Dentistry at the University of Alberta have discovered a new way by which metabolism is linked to the regulation of DNA, the basis of our genetic code. The findings may have important implications for the understanding of many common diseases, including cancer.

Study: Obesity causes changes in colon that may lead to colorectal cancer

Obesity, rather than diet, causes changes in the colon that may lead to colorectal cancer, according to a study in mice by the National Institutes of Health. The finding bolsters the recommendation that calorie control and frequent exercise are not only key to a healthy lifestyle, but a strategy to lower the risk for colon cancer, the second leading cause of cancer-related death in the United States.

Gladstone-led study sheds light on critical molecular process

One of biology's most fundamental processes is something called transcription. It is just one step of many required to build proteins-and without it life would not exist. However, many aspects of transcription remain shrouded in mystery. But now, scientists at the Gladstone Institutes are shedding light on key aspects of transcription, and in so doing are coming even closer to understanding the importance of this process in the growth and development of cells-as well as what happens when this process goes awry.

Study shows enhancer RNA molecules may open new avenues for gene therapy

A study investigating the function of the recently discovered enhancer RNA molecules may open new avenues for gene therapy. According to the study researchers, altering the production and function of these molecules could affect the expression of genes and, in consequence, possibly also the progression of various diseases.

Researchers find vital enzyme complex that gets elevated in many cancers

A team of researchers from Philadelphia and Norway has determined the structure of an enzyme complex that modifies one end of most human proteins and is made at elevated levels in numerous forms of cancer. A study in Nature Structural & Molecular Biology, led by researchers at The Wistar Institute, depicts the structure and the means of action of a protein complex called NatA.

Scientists discover molecular switch that determines death or survival of cell

The study is the result of a collaboration of scientists at Karolinska Institutet in Sweden, University of Michigan, and University of California San Diego, USA, who were interested in finding out whether autophagy can be affected by events in the cell nucleus. Surprisingly, they discovered that a signal chain in the nucleus serves as a kind of molecular switch that determines whether the cell dies or survives.
