Rice University computational study tracks regulatory mechanisms of E. coli cells

Environment is not the only factor in shaping regulatory patterns -- and it might not even be the primary factor, according to a new Rice University study that looks at how cells' protein networks relate to a bacteria's genome.

Study provides comprehensive blueprint for understanding diabetes

Australian scientists have charted the path of insulin action in cells in precise detail like never before. This provides a comprehensive blueprint for understanding what goes wrong in diabetes.

Caltech biologists show that microRNA-146a protects stem cells during inflammation

When infections occur in the body, stem cells in the blood often jump into action by multiplying and differentiating into mature immune cells that can fight off illness. But repeated infections and inflammation can deplete these cell populations, potentially leading to the development of serious blood conditions such as cancer.

Vitamin C kills drug-resistant TB bacteria in lab

In a striking, unexpected discovery, researchers at Albert Einstein College of Medicine of Yeshiva University have determined that vitamin C kills drug-resistant tuberculosis bacteria in laboratory culture.

Nutritional supplement improves functioning of genes involved in degenerative brain disorders

Widely available in pharmacies and health stores, phosphatidylserine is a natural food supplement produced from beef, oysters, and soy. Proven to improve cognition and slow memory loss, it's a popular treatment for older people experiencing memory impairment.

Grifols signs worldwide licensing agreement for Aradigm's Pulmaquin

Grifols, S.A. and Aradigm Corporation today announced the signing of an exclusive, worldwide license for Aradigm's proprietary formulations of inhaled ciprofloxacin (Pulmaquin and Lipoquin) for the treatment of severe respiratory diseases, including non-cystic fibrosis bronchiectasis.

Scientists bioengineer novel molecule to kill tumour cells

Scientists from Nanyang Technological University and Lund University, Sweden, have bioengineered a novel molecule which has been proven to successfully kill tumour cells.

Scientists design 'fishing' technique to show health benefits of foods

New research suggests that a compound abundant in the Mediterranean diet takes away cancer cells' "superpower" to escape death.

Researchers pinpoint catalytic trigger for onset of Alzheimer's disease

Researchers have pinpointed a catalytic trigger for the onset of Alzheimer's disease - when the fundamental structure of a protein molecule changes to cause a chain reaction that leads to the death of neurons in the brain.

Researchers examine how BRD4 contributes to sustained presence of NF-kappa B in cancer cells

In a new study described in the journal Oncogene, researchers reveal how a key player in cell growth, immunity and the inflammatory response can be transformed into a primary contributor to tumor growth.

Novel medicine for chronic wound treatment

Every 20 seconds, a limb is lost as a consequence of diabetic foot ulcer that does not heal. To date, medical solutions that can change this situation are very limited.

Keystone molecules in chemical communication, defense have dominant consequences in nature

Naturally occurring "keystone" molecules that have powerful behavioral effects on diverse organisms often play large but unrecognized roles in structuring ecosystems, according to a theory proposed in the June issue of BioScience.

Changes in specific proteins contribute to 'leaky-gut' wall

Scientists at Trinity College Dublin have made an important advance in understanding the biological factors that keep the lining of the gut wall intact. Associate Professor, Maria O'Sullivan at Trinity's School of Medicine and St James's Hospital and colleagues, showed that changes in specific proteins may contribute to a 'leaky-gut' wall which may have important implications for common chronic digestive diseases such as irritable bowel syndrome and inflammatory bowel disease.

Study suggests need for better anti-rejection therapies

Transplant researchers at the University of Pittsburgh School of Medicine challenge a long-held assumption about how biologic pathways trigger immune system rejection of donor organs in a report published online today in the Journal of Clinical Investigation.

Researchers demonstrate how EGF accelerates division of cell nucleus

Biologists at Heidelberg University have discovered new approaches for the treatment of cancer. They investigated how a special signalling molecule, the epidermal growth factor (EGF), stimulates the separation of chromosomes in the cell. The researchers were able to demonstrate that EGF accelerates the division of the cell nucleus, i.e. mitosis, as well as boosts precision in chromosome segregation.

Vijay Tiwari from IMB receives Bruno Speck Award from Swiss Foundation of Haematological Research

Dr Vijay Tiwari, a Group Leader at the Institute of Molecular Biology (IMB) in Mainz, has been awarded the Bruno Speck Award by the Swiss Foundation of Haematological Research. The award recognises outstanding work by young scientists in the fields of haematology and stem cell research.

Findings could help develop new approaches to treat depression and memory loss in the elderly

Scientists have known for some time that exercise induces neurogenesis in a specific brain region, the hippocampus. However, until this study, the underlying mechanism was not fully understood.

Inhibiting powerful protein with new agents may supply broad benefit for lymphoma patients

A soon-to-be-tested class of drug inhibitors were predicted to help a limited number of patients with B-cell lymphomas with mutations affecting the EZH2 protein.

Researchers identify microRNA-155 as prognostic marker, treatment target in patients with AML

A study has identified microRNA-155 as a new independent prognostic marker and treatment target in patients with acute myeloid leukemia that has normal-looking chromosomes under the microscope (that is, cytogenetically normal acute myeloid leukemia, or CN-AML).
