Genetic, lifestyle factors and HRT increase risk of breast cancer

The risk of breast cancer is increased by genetic and lifestyle factors such as the inherited BRCA2 gene, age of having first child, or use of hormone replacement therapy (HRT).

MC3R gene plays an important role in maintaining steady weight

Against the backdrop of the growing epidemic of obesity in the United States, scientists from the Florida campus of The Scripps Research Institute have made an important new discovery regarding a specific gene that plays an important role in keeping a steady balance between our food intake and energy expenditure. The study may help scientists better understand the keys to fighting obesity and related disorders such as diabetes.

Experimental drug selectively destroys blood supply of fat tissue and decreases body fat

Obese rhesus monkeys lost on average 11 percent of their body weight after four weeks of treatment with an experimental drug that selectively destroys the blood supply of fat tissue, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports in Science Translational Medicine.

Hirano bodies may play a protective role in progression of Alzheimer's

Hirano bodies are almost indescribably tiny objects found in nerve cells of people suffering from conditions such as Alzheimer's, mad cow and Lou Gehrig's diseases. Yet for decades, researchers weren't sure if these structures helped cause the conditions or appeared after onset of the disease and had some other role.

Scientists identify distinct tobacco transporter for nicotine metabolism

A team of Virginia Tech and Purdue University scientists have identified a distinct transporter used by tobacco plant cells for nicotine metabolism. The research appears in the Oct. 17 online before print issue of the Proceedings of the National Academy of Sciences (PNAS) in the article, "A tobacco nicotine uptake permease effects alkaloid metabolism."

Complexities of DNA repair

An international team of scientists led by UC Davis researchers has discovered that DNA repair in cancer cells is not a one-way street as previously believed. Their findings show instead that recombination, an important DNA repair process, has a self-correcting mechanism that allows DNA to make a virtual u-turn and start over.

Australian researchers make a quantum leap in understanding key cell structures

Researchers in Australia and the UK have made a world first discovery that will provide the most accurate understanding to date of the structure and function of the most important energy converting protein, critical to the function of all organs and a cause of disease when malfunctioning.

Four-gene signature may predict patients at higher risk of OSCC recurrence

Oral Squamous Cell Carcinoma (OSCC) is responsible for nearly a quarter of all head and neck cancers. It is one of the leading causes of cancer death - largely due to the failure of current histological procedures in predicting the recurrence of the disease. New research published in BioMed Central's open access journal BMC Cancer shows that a four-gene signature may accurately predict which patients are at higher risk of OSCC recurrence.

Fred Hutchinson Cancer Research Center scientist wins NIH Director's Early Indpendence Award

Carissa Perez Olsen, Ph.D., a Weintraub Scholar in the Basic Sciences Division of Fred Hutchinson Cancer Research Center, is the recipient of the National Institutes of Health Director's Early Independence Award, announced today. She is among the first group of 10 junior U.S. investigators to receive the honor.

Two TGen students receive SRP grants for antibiotic resistance and Alzheimer's research

Two Arizona university graduate students working at the Translational Genomics Research Institute (TGen) have each received $50,000 grants from the Salt River Project.

Researchers discover cellular origins of breast cancer

Identifying the cellular origins of breast cancer might lead to earlier diagnosis and more efficient management of the disease. New research led by Charlotte Kuperwasser of Tufts University School of Medicine (TUSM) has determined that common forms of breast cancer originate from breast cells known as luminal epithelial cells while rarer forms of breast cancer, such as metaplastic carcinomas, originate from basal epithelial cell types.

Combining cell biology and molecular genetics for single-cell research

Fluidigm Corporation has announced a collaboration with BD Biosciences, a segment of BD (Becton, Dickinson and Company), to co-host a public seminar series on the isolation and analysis of single cells. Entitled 'A Powerful Technique for Single-Cell Analysis', the public seminar series will showcase cell isolation using the BD FACSAria™ III Cell Sorter and analysis using the Fluidigm BioMark™ HD System.

Abnormal levels of lysophosphatidic acid can trigger congenital hydrocephalus

Scientists at The Scripps Research Institute have found what may be a major cause of congenital hydrocephalus, one of the most common neurological disorders of childhood that produces mental debilitation and sometimes death in premature and newborn children.

Discovery of a key protein’s role in cell clearance could impact future treatments of autoimmune diseases, obesity and atherosclerosis

The healthy human body is extremely efficient at cleaning house. Every day, we purge 100 to 200 billion dead or dying cells – a process called cell clearance, which is fundamental in our ability to maintain a healthy physiological balance and prevent a number of chronic diseases. Professional cleaning cells, called phagocytes, are responsible for ridding the body of dead, or ‘apoptotic,’ cells.

Researchers discover how yeast cells identify, attach to human tissue and cause infection

Researchers are a step closer towards creating a new class of medicines and vaccines to combat drug-resistant and deadly strains of fungal infections, following a new study published today in Proceedings of the National Academy of Sciences.

Stem cell therapy for baldness

Researchers have found that molecular signals from stem cells within the skin's fatty layer trigger hair growth in mice. This could mean new treatments for baldness in people.

New chemical compounds show promise against set of protein-folding diseases

Collaborating researchers at Stanford University and The Scripps Research Institute have identified chemical compounds that show promise as potential therapeutics for a set of medical conditions caused by the abnormal clumping together of a protein known as transthyretin.
