Chemists create new molecule that can tangle inside the DNA for up to 16 days

Chemists at The University of Texas at Austin have created a molecule that's so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates itself, much longer than any other molecule reported.

23andMe, Cleveland Clinic to discover how genes and environment influence PD

In an effort to study the interactions between genomics and Parkinson's disease, Cleveland Clinic has joined the ongoing efforts of 23andMe, a leading personal genetics company, to recruit Parkinson's patients to participate in research by contributing their DNA to a research database and completing online surveys about their health.

Chemists adapt natural strategies to improve performance of DNA detectors

Over their 3.8 billion years of evolution, living organisms have developed countless strategies for monitoring their surroundings. Chemists at UC Santa Barbara and University of Rome Tor Vergata have adapted some of these strategies to improve the performance of DNA detectors. Their findings may aid efforts to build better medical diagnostics, such as improved HIV or cancer tests.

HB-EGF plays a critical role during retina regeneration

University of Michigan Health System research into the mechanisms by which zebrafish are able to regenerate damaged retinas after injury suggests new strategies for one day being able to do the same in humans - potentially allowing doctors to slow or reverse conditions like macular degeneration and glaucoma.

Disrupted sleep may lead to build-up of amyloid plaques

The amount and quality of sleep you get at night may affect your memory later in life, according to research that was released today and will be presented at the American Academy of Neurology's 64th Annual Meeting in New Orleans April 21 to April 28, 2012.

Mass spectroscopy identifies total of 1,210 UCB proteins

Blood tests have been a mainstay of diagnostic medicine since the late 19th century, offering a wealth of information concerning health and disease. Nevertheless, blood derived from the human umbilical cord has yet to be fully mined for its vital health information, according to Rolf Halden, a researcher at Arizona State University's Biodesign Institute.

Study finds BRCA1 mutations in nearly one in five TN breast cancer patients

Leading breast cancer experts are calling for women under 50 who are diagnosed with triple-negative (TN) breast cancer to be offered testing for faults in the BRCA1 gene, according to a report published in the British Journal of Cancer.

Tissues in SIV-infected monkeys can ramp up production of Tregs

Tissue in monkeys infected with a close relative of HIV can ramp up production of a type of T cell that actually weakens the body's attack against the invading virus. The discovery, in lymph nodes draining the intestinal tract, could help explain how the HIV virus evades the body's immune defenses.

Tetrahydrobiopterin plays a key role in arterial health of women

Researchers studying why arteries stiffen in postmenopausal women have found a specific chemical cofactor that dramatically improves vascular function.

Researchers investigate role of a MYC family gene in ovarian cancer

The role of a known cancer-causing gene in the development of the most lethal type of ovarian cancer is being investigated by researchers from the Walter and Eliza Hall Institute after they were awarded a Cure Cancer Australia Foundation (CCAF) grant.

mRNA sequencing reveals transcriptomic landscape of breast cancer

GW Cancer Research Team in the Department of Biochemistry and Molecular Biology, in the School of Medicine and Health Sciences, published a study that is the first of its kind to use mRNA sequencing to look at the expression of genome, at a unprecedented resolution at the current time, in three types of breast cancer.

New information about IL-6 protein's role in development of neurological disorders

A UT Dallas study is revealing new information about a key protein's role in the development of epilepsy, autism and other neurological disorders. This work could one day lead to new treatments for the conditions.

U-M's first human embryonic stem cell line to be placed on the U.S.NIH registry

The University of Michigan's first human embryonic stem cell line will be placed on the U.S. National Institutes of Health's registry, making the cells available for federally-funded research. It is the first of the stem cell lines derived at the University of Michigan to be placed on the registry.

Curcumin prolongs life and enhances activity of fruit flies with AD

Curcumin, a substance extracted from turmeric, prolongs life and enhances activity of fruit flies with a nervous disorder similar to Alzheimers. The study conducted at Link-ping University, indicates that it is the initial stages of fibril formation and fragments of the amyloid fibrils that are most toxic to neurons.

New group of compounds may protect brain cells from inflammation

Scientists at Emory University School of Medicine have identified a new group of compounds that may protect brain cells from inflammation linked to seizures and neurodegenerative diseases.

New WSU model system focuses on causes of everyday MS symptoms

Annoying, frustrating symptoms like difficulty hearing or remembering things can complicate everyday living for multiple sclerosis (MS) patients, but most research to date has focused on the disease's less frequent but more debilitating consequences.

Study confirms increased risk of cancers linked with Lynch syndrome

People with Lynch syndrome have a genetic mutation that gives them a high risk of several types of cancer including bowel cancer. The genes that are damaged can't repair any errors that occur in our DNA.

Study shows how malaria parasite changes into banana form before sexual reproduction

New research from the University of Melbourne shows how the malaria parasite (Plasmodium falciparum) changes into a banana shape before sexual reproduction, a finding that could provide targets for vaccine or drug development and may explain how the parasite evades the human immune system.

Scientists identify and describe molecular mechanism behind holoprosencephaly

Researchers of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch have now identified and described a molecular mechanism underlying the most common malformation of the brain in humans. In holoprosencephaly (HPE), the forebrain (prosencephalon) is only incompletely formed.

Epigenetic mechanisms maintain tolerance in T cells specific for self antigens

At the most basic level, the immune system must distinguish self from non-self, that is, it must discriminate between the molecular signatures of invading pathogens (non-self antigens) and cellular constituents that usually pose no risk to health (self-antigens).
