Biologists unravel why some people infected with HIV have more virus

Biologists at UC San Diego have unraveled the anti-viral mechanism of a human gene that may explain why some people infected with HIV have much higher amounts of virus in their bloodstreams than others.

Anesthetics and proteins: understanding the interactions

Spanish scientists at the University of the Basque Region and the University of La Rioja have combined mass-resolved electronic spectroscopy and ab initio calculations to model the interactions of anesthetics with proteins.

Molecular similarity between one sub-type of breast cancer and ovarian cancer

A team of scientists with The Cancer Genome Atlas program reports their genetic characterization of 800 breast tumors, including finding some of the genetic causes of the most common forms of breast cancer, providing clues for new therapeutic targets, and identifying a molecular similarity between one sub-type of breast cancer and ovarian cancer.

New findings on how naked mole-rats adapt to acidic environments

Naked mole-rats evolved to thrive in an acidic environment that other mammals, including humans, would find intolerable. Researchers at the University of Illinois at Chicago report new findings as to how these rodents have adapted to this environment.

Researchers solve mystery of radial glial cells

Researchers at Cold Spring Harbor Laboratory (CSHL) have solved an important piece of one of neuroscience's outstanding puzzles: how progenitor cells in the developing mammalian brain reproduce themselves while also giving birth to neurons that will populate the emerging cerebral cortex, the seat of cognition and executive function in the mature brain.

Alzheimer's can involve mixture of proteins from different neurodegenerative diseases

Neurodegenerative diseases such as Alzheimer's or Parkinson's are characterised by the loss of nerve cells and the deposition of proteins in the brain tissue. A group of researchers led by Gabor G. Kovacs from the Clinical Institute of Neurology at the MedUni Vienna has now demonstrated that Alzheimer's disease does not just - as previously believed - involve the proteins that are attributed to Alzheimer's, but instead the condition can involve a mixture of interacting proteins from different neurodegenerative diseases.

Denosumab effective in treating giant-cell tumor of the bone

Treatment with denosumab, a drug targeted against a protein that helps promote bone destruction, decreased the number of tumor giant cells in patients with giant-cell tumor of the bone, and increased new bone formation, according to the results of a phase II study published in Clinical Cancer Research, a journal of the American Association for Cancer Research.

Genomic analysis of E. coli shows multiple steps to evolve new trait

Several years ago researchers at Michigan State University (MSU) reported discovering a novel, evolutionary trait in a long-studied population of Escherichia coli, a rod-shaped bacterium commonly found in the lower intestine of mammals. The E. coli added a helping of citrate to its traditional diet of glucose, even though other E. coli can't consume citrate in the presence of oxygen.

Adding missing protein to infertile human sperm can 'kick-start' its ability to fertilise eggs

Adding a missing protein to infertile human sperm can 'kick-start' its ability to fertilise an egg and dramatically increase the chances of a successful pregnancy, a team of Cardiff University scientists have uncovered.

NCI awards Provocative Questions grant to Mount Sinai School of Medicine researchers

Two Mount Sinai School of Medicine researchers are among a select group of scientists from around the world who have been recognized by the National Cancer Institute (NCI) for their quest to answer the most pressing questions about cancer. Stuart Aaronson, MD, Professor and Chair of Oncological Sciences and Ross Cagan, PhD, Professor of Oncological Sciences at Mount Sinai, have received the NCI's new "Provocative Questions" grant, which was established to explore the important yet less obvious questions about cancer that may have been neglected in this era of significant discovery.

Loss of IGSF1 gene function causes central hypothyroidism

Loss of function in the X-linked immunoglobulin superfamily member 1 (IGSF1) gene causes central hypothyroidism, testicular enlargement, and variable prolactin deficiency, according to data presented at the 82nd Annual Meeting of the American Thyroid Association in Québec City, Québec, Canada.

Iron transport may contribute to diabetes

Scientists have been trying to explain the causes of diabetes for many years. Researchers at the University of Copenhagen and Novo Nordisk A/S have now shown that the increased activity of one particular iron-transport protein destroys insulin-producing beta cells. In addition, the new research shows that mice without this iron transporter are protected against developing diabetes.

MiR-34a plays a key role in obesity

Scientists have identified a key molecular player in a chain of events in the body that can lead to fatty liver disease, Type II diabetes and other metabolic abnormalities associated with obesity. By blocking this molecule, the researchers were able to reverse some of the pathology it caused in obese mice.

PNAS: Ras proteins bring tension to the phosphate chain

Proteins accelerate certain chemical reactions in cells by several orders of magnitude. The molecular mechanism by which the Ras protein accelerates the cleavage of the molecule GTP and thus slows cell growth is described by biophysicists at the Ruhr-Universit-t Bochum led by Prof. Dr. Klaus Gerwert in the Online Early Edition of the journal PNAS.
