New research shows that the brain can produce and release estrogen

A University of Wisconsin-Madison research team reports today that the brain can produce and release estrogen - a discovery that may lead to a better understanding of hormonal changes observed from before birth throughout the entire aging process.

Findings suggest new approach for treating inflammatory bone diseases and skeletal metastases

The skeleton is constantly being remodelled by the breakdown of old bone by cells called osteoclasts and the formation of new bone by cells called osteoblasts. This coordinated activity is essential for maintaining healthy bone. However, excessive osteoclast activity leads to bone destruction in skeletal diseases such as osteoporosis, rheumatoid arthritis and cancer metastases in bone. A family of signaling enzymes known as phosphatidylinositol 3-kinases control diverse cell functions but, up until now, little was known about the function of specific PI3K isoforms in osteoclasts.

Biologists discover how nerve cells recycle tiny vesicles

University of Utah and German biologists discovered how nerve cells recycle tiny bubbles or "vesicles" that send chemical nerve signals from one cell to the next. The process is much faster and different than two previously proposed mechanisms for recycling the bubbles.

New report analyzes growth and development of stem cell field

Elsevier, EuroStemCell, and Kyoto University's Institute for Integrated Cell-Material Sciences, today released "Stem Cell Research report: Trends and Perspectives on the Evolving International Landscape" at the World Stem Cell Summit. This new, comprehensive analysis of the growth and development of the stem cell field as a whole, closely examines the research landscape for embryonic stem cell, human embryonic stem cell and induced pluripotent stem cell.

Research: Low level of daily exposure to sunlight can cause skin damage

A low level of daily exposure to a common component of sunlight can cause skin damage at the molecular level after just a few days, new University of Michigan Medical School research shows.

B2G2 component of grape seed extract induces apoptosis in prostate cancer cells

A University of Colorado Cancer Center study published online ahead of print in the journal Nutrition and Cancer describes the laboratory synthesis of the most active component of grape seed extract, B2G2, and shows this synthesized compound induces the cell death known as apoptosis in prostate cancer cells while leaving healthy cells unharmed.

TLR4 antibody-mediated signaling system in apoptosis of hippocampal neurons

Toll-like receptor 4 (TLR4) antibody, protein kinase B (AKT) inhibitor, LY 294002, and glycogen synthase kinase 3β (GSK-3β) inhibitor, LiCl, were used by Yu He and colleagues from Nantong University, China to attenuate or augment the effects of the TLR4-phosphatidylinositol 3 kinase (PI3K)/AKT-GSK-3β signaling pathway so as to identify the participation of this signaling system in the apoptosis of hippocampal neurons.

UCSB researcher tracks source of E280A gene mutation responsible for early-onset Alzheimer's

The age and origin of the E280A gene mutation responsible for early-onset Alzheimer's in a Colombian family with an unusually high incidence of the disease has been traced to a single founder dating from the 16th century.

New method for counting tumor-fighting cells to predict ovarian cancer

One way to predict survival of many types of cancer is by counting the number of tumor-attacking immune cells that have migrated into the tumor in an effort to eradicate it - a sign of the body's immune response to the cancer. However, quantifying these armies of immune cells has been difficult - until now.

Tongue twisters can open windows into the brain's speech-planning processes

Tongue twisters are not just fun to say; it turns out that these sound-related slip-ups can also open windows into the brain's speech-planning processes. A team from the Massachusetts Institute of Technology (MIT) will report new insights gleaned from a comparison of two types of tongue twisters at the 166th meeting of the Acoustical Society of America (ASA), held Dec. 2-6, 2013, in San Francisco, Calif

Stomach circadian clock limits food intake to specific times of day

University of Adelaide researchers have discovered the first evidence that the nerves in the stomach act as a circadian clock, limiting food intake to specific times of the day.

Scientists receive $4M grant to identify biomarker for secondary injuries associated with brain

In an effort to lower medical costs, identify patients at risk for injury, and speed patient recovery, scientists will attempt to identify a molecular signal that indicates severity of brain-injury during a $4 million, five-year federal grant to Barrow Neurological Institute at St. Joseph's Hospital and Medical Center, Phoenix Children's Hospital and the Translational Genomics Research Institute (TGen).

Study: Track-side noise may exceed 8,500% of person's daily recommended noise exposure

As an acoustical engineer, Craig Dolder - currently a graduate student at the University of Texas, Austin - knew that loud noises can damage hearing. Even so, when Canada's Formula 1 Grand Prix coincided with an Acoustical Society of America (ASA) meeting that he was attending in Montreal, Quebec, earlier this year, Dolder was drawn to the racetrack and the deafening roar of the Formula 1 engines.

New research offers fresh insights to drug designers searching for better pain treatments

In a technical tour de force, UC San Francisco scientists have determined, at near-atomic resolution, the structure of a protein that plays a central role in the perception of pain and heat.

Blocking Cdh1 protein could accelerate development of new therapies targeting cancer

The laboratory of Marcos Malumbres, who is head of the Spanish National Cancer Research Centre's (CNIO) Cell Division & Cancer Group, working alongside Isabel Fari-as' team from the University of Valencia, shows, in a study published today in the journal Nature Communications, how in mice the elimination of the Cdh1 protein -a sub-unit of the APC/C complex, involved in the control of cell division-prevents cellular proliferation of rapidly dividing cells.

Baicalin inhibits colistin sulfate-induced apoptosis of PC12 cells

Baicalin, a type of flavonoid extracted from the dried root of Scutellaria baicalensis georgi, has been shown to effectively inhibit cell apoptosis. Colistin sulfate, a cyclic cationic polypeptide antibiotic, has been shown to have renal and neurological side effects.

UCLA researchers discover how prostate cancer stem cells evolve as the disease grows

UCLA researchers have discovered how prostate cancer stem cells evolve as the disease progresses, a finding that could help point the way to more highly targeted therapies.

BIDMC study shows carbon monoxide may have a role to play in treating cancer

In recent years, research has suggested that carbon monoxide, the highly toxic gas emitted from auto exhausts and faulty heating systems, can be used to treat certain inflammatory medical conditions. Now a study led by a research team at Beth Israel Deaconess Medical Center (BIDMC) shows for the first time that carbon monoxide may also have a role to play in treating cancer.

Tet1 helps erase epigenetic imprints from genome ahead of egg, sperm development

A protein called Tet1 is partly responsible for giving primordial germ cells a clean epigenetic slate before developing into sperm and egg cells, according to a new study by researchers at Boston Children's Hospital.

Researchers discover how PC7 protein affects certain types of cognitive performance

A team of Montr-al researchers at the IRCM led by Dr. Nabil G. Seidah, in collaboration with Dr. William C. Wetsel's team at Duke University in the United States, discovered that the protein PC7 plays a critical role in the brain by affecting certain types of cognitive performance such as anxiety, learning and emotional memory. Their results, recently published in the scientific journals Proceedings of the National Academy of Sciences (PNAS) and Nature, could have a significant impact on regulating behaviour related to anxiety disorders and trauma.
