Disrupting estrogen pathway can halt expansion of breast cancer stem cells: Research

Breast cancer stem cells (CSCs), the aggressive cells thought to be resistant to current anti-cancer therapies and which promote metastasis, are stimulated by estrogen via a pathway that mirrors normal stem cell development.

New direct labeling system for oocytes, embryos

Researchers from the Department of Cell Biology, Physiology and Immunology at Universitat Autònoma de Barcelona (UAB), in collaboration with researchers from the Institute of Microelectronics of Barcelona (IMB-CNM) of the Spanish National Research Council (CSIC), have developed an identification system for oocytes and embryos in which each can be individually tagged using silicone barcodes.

Neuralstem files NSI-189 IND with FDA for Phase I safety trials for major depression

Neuralstem, Inc. announced that it has filed an Investigational New Drug (IND) application with the United States Food and Drug Administration (FDA) to begin two Phase I safety trials to test NSI-189, its first small molecule compound, for the treatment of major depression. NSI-189 is a proprietary new chemical entity discovered by Neuralstem that stimulates new neuron growth in the hippocampus, an area of the brain that is believed to be involved in depression.

Study finds phenotypic plasticity among melanoma cells

University of Michigan researchers have determined that most types of melanoma cells can form malignant tumors, providing new evidence that the deadliest form of skin cancer does not conform to the increasingly popular cancer stem cell model.

Researchers discover circadian rhythms regulate fat metabolism

UC Irvine researchers have discovered that circadian rhythms the internal body clock regulate fat metabolism. This helps explain why people burn fat more efficiently at certain times of day and could lead to new pharmaceuticals for obesity, diabetes and energy-related illnesses.

Fisetin slows onset of motor problems, delays death in three models of Huntington's disease: Study

Fisetin, a naturally occurring compound found in strawberries and other fruits and vegetables, slows the onset of motor problems and delays death in three models of Huntington's disease, according to researchers at the Salk Institute for Biological Studies. The study, published in the online edition of Human Molecular Genetics, sets the stage for further investigations into fisetin's neuroprotective properties in Huntington's and other neurodegenerative conditions.

Domainex, Sigma-Aldrich enter collaboration to study epigenetic proteins

Domainex Ltd., the Contract Research Organization committed to excellence in drug discovery, today announced a collaboration with Sigma-Aldrich that will provide essential tools, including biochemical assays and monoclonal antibodies, for the study of proteins involved in the rapidly developing field of epigenetics. These epigenetic proteins regulate DNA expression and can be critical to cancer and stem cell biology research. Funding from the UK Government-backed Technology Strategy Board will support this work.

Scientists unveil mechanism of liver regeneration

The liver's unique ability among organs to regenerate itself has been little understood. Now Weill Cornell Medical College scientists have shed light on how the liver restores itself by demonstrating that endothelial cells the cells that form the lining of blood vessels play a key role.

MqsA and MqsR protein complex can disrupt drug-resistant biofilm formation

When a foreign object such as a catheter enters the body, bacteria may not only invade it but also organize into a slick coating - a biofilm - that is highly resistant to antibiotics. Like sophisticated organized crime rings, biofilms cannot be defeated by a basic approach of conventional means. Instead doctors and drug developers need sophisticated new intelligence that reveals the key players in the network and how they operate. New research led by biologists at Brown University provides exactly that dossier on some key proteins in the iconic bacterium E. coli.

Contraceptive, antiviral gel using bee venom wins 2010 Gates Foundation grant

A vaginal gel that affords both contraception and HIV protection using nanoparticles that carry bee venom is one of the bold, unconventional ideas that won a 2010 Grand Challenges Explorations grant from the Bill & Melinda Gates Foundation.

Johns Hopkins scientists identify protein mechanism that regulates cell division

By tracking the flow of information in a cell preparing to split, Johns Hopkins scientists have identified a protein mechanism that coordinates and regulates the dynamics of shape change necessary for division of a single cell into two daughter cells.

Study explains link between morbid obesity and metabolic syndrome

Scientists have found that the fat cells and tissues of morbidly obese people and animals can reach a limit in their ability to store fat appropriately. Beyond this limit several biological processes conspire to prevent further expansion of fat tissue and in the process may trigger other health problems.

UC researchers receive four-year grant to study mechanism of malarial parasite replication in RBCs

Today, about half the world's population lives in areas at risk of malaria transmission. The disease is transmitted to humans through bites from mosquitoes, and each year causes hundreds of thousands of deaths worldwide, with about 1,500 of these in the United States.
