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.

SENP1 prevents STAT5 from becoming trapped in nucleus

When SUMO grips STAT5, a protein that activates genes, it blocks the healthy embryonic development of immune B cells and T cells unless its nemesis breaks the hold, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports today in Molecular Cell.

DNA stays too tightly wound in brain cells of patients with schizophrenia

Scientists at The Scripps Research Institute have discovered that DNA stays too tightly wound in certain brain cells of schizophrenic subjects. The findings suggest that drugs already in development for other diseases might eventually offer hope as a treatment for schizophrenia and related conditions in the elderly.

Animal study offers insights into possible drug targets to improve memory as we age

Drugs that affect the levels of an important brain protein involved in learning and memory reverse cellular changes in the brain seen during aging, according to an animal study in the December 7 issue of The Journal of Neuroscience. The findings could one day aid in the development of new drugs that enhance cognitive function in older adults.

Researchers manipulate life span of yeast by mutating chemical residues

Collaborations between Johns Hopkins and National Taiwan University researchers have successfully manipulated the life span of common, single-celled yeast organisms by figuring out how to remove and restore protein functions related to yeast aging.

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.

Researchers identify surprising mechanism that facilitates protein interactions

Research led by St. Jude Children's Research Hospital scientists has identified an unexpected mechanism facilitating some protein interactions that are the workhorses of cells and, in the process, identified a potential new cancer drug development target.

New VAAST software tool can identify disease-causing mutations in rare genetic disorders

Harnessing the new generation of rapid, highly accurate gene-sequencing techniques, a research team has identified the disease-causing mutation in a newly characterized rare genetic disease, by analyzing DNA from just a few individuals.

Gestational high-fat diet programs woman's baby for future diabetes

A high-fat diet during pregnancy may program a woman's baby for future diabetes, even if she herself is not obese or diabetic, says a new University of Illinois study published in the Journal of Physiology.

Exacerbate-reverse' approach can identify potential therapy for fatal childhood disease

Many genes that cause human diseases have parallel genes in other organisms, including yeast. Now Columbia University researchers have used an innovative yeast-based screening method to identify a possible treatment for the fatal childhood disease Niemann-Pick C.

Researchers study role of acetylation in Alzheimer's disease

Researchers at the University of Pennsylvania School of Medicine have determined that a well-known chemical process called acetylation has a previously unrecognized association with one of the biological processes associated with Alzheimer's disease and related disorders. The findings were published in the latest issue of Nature Communications.

Research: CREBBP mutation may help cancer resist steroid treatment, fuel ALL's return

Despite dramatically improved survival rates for childhood acute lymphoblastic leukemia, relapse remains a leading cause of death from the disease. Work led by St. Jude Children's Research Hospital investigators identified mutations in a gene named CREBBP that may help the cancer resist steroid treatment and fuel ALL's return.

Aging-associated protein deficiency may lead to positive breast cancer in women

The most common type of breast cancer in older women - estrogen and progesterone receptor positive breast cancer - has been linked to a protein that fends off aging-related cellular damage.

Acetylation complex fits like a halo over a histone

To understand the emerging science of epigenetics-a field that describes how genes may be regulated without altering the underlying DNA itself-scientists are deciphering the many ways in which enzymes act on the proteins surrounding DNA within cells.

Study highlights role of SIRT1 protein as tumor suppressor in prostate cancer

Researchers from the Kimmel Cancer Center at Jefferson and two other institutions have discovered new evidence that suggests the "longevity" protein SIRT1, known for its life-spanning effects in different species, can inhibit the development of a known precursor to prostate cancer, prostatic intraepithelial neoplasia.
