COX-1 and COX-2 enzymes may be blocked by pain medications

COX-1 and COX-2 enzymes may be blocked by pain medications such as Advil and Vioxx in a more complex manner than was previously understood, a Queen's University study has found.

Canadian researchers close in on new treatments for type 2 diabetes

Researchers funded by the Canadian Institutes of Health Research (CIHR) and the Canadian Diabetes Association (CDA) have identified an unsuspected role of a protein named SHP-1 that could constitute a new therapeutic path against Type 2 Diabetes.

Level of selenium-containing proteins in the body instrumental in preventing cancer

Selenium, an essential dietary mineral that can act as an antioxidant when incorporated into proteins, has been shown in many studies to reduce the incidence of cancers -- notably lung, colorectal and prostate.

Bedsores and bald hides: novel roles revealed for a "scaffolding" protein

A protein long thought to provide only mechanical support for keeping cells and tissues from literally falling apart turns out to have much wider utility.

17 May 2006

Study holds promise for malarial susceptibility test

Cell and animal studies conducted jointly by scientists at Johns Hopkins, Yale and other institutions have uncovered at least one important contributor to the severe anemia that kills almost half of the 2 million people worldwide who die each year of malaria.

c-myc gene found to play role in immune system

c-myc, a gene commonly involved in cancer onset, has been found to have a role in the immune system's normal function according to a study published in Blood.

Extension of embryo screening will help reduce serious illness

A fertility watchdog in Britain, the Human Fertilisation and Embryology Authority (HFEA), has given approval for the extension of embryo screening to cover a wider range of mutated genes, in the main those which raise the risk of cancer in later life.

New discovery about role of sugar in cell communication

A research team from Uppsala University has uncovered an entirely new mechanism for how communication between cells is regulated.

9 May 2006

Gene silencing protein discovered

A team of researchers, including biologists at Washington University in St. Louis, has discovered the key role one protein plays in a major turn-off -in this case, the turning off of thousands of nearly identical genes in a hybrid plant.

Allergy-free soybeans

Researchers have isolated two Chinese soybean lines that grow without the primary protein linked to soy allergies in children and adults.

Researchers have made important progress in regenerating hearing cells

Massachusetts General Hospital (MGH) researchers have made important progress in their ongoing effort to regenerate the inner ear's hair cells, which convert sound vibrations to nerve impulses.

Identification of CPT1c gene that the brain needs to manage body weight

Working with genetically engineered mice, Johns Hopkins scientists have interfered with the brain's ability to control an animal's response to a high-fat diet.

Protein produced by immune cells during malaria infection triggers severe anemia

Richard Bucala and colleagues at Yale University show that immune cells in mice with malaria secrete a protein called MIF, which decreases the production of red blood cells (RBCs) from the bone marrow. The study appears in The Journal of Experimental Medicine.

3 May 2006

Blood cancers may be caused by inactivation of a "tumor suppressor" gene

The discovery of a gene, called PRDM1, as a tumor suppressor sheds new light on the cause - and possible treatment - of diffuse large B-cell lymphomas (DLBCLs), a cancer of the blood's B-lymphocytes. DLBCLs comprise about 30 percent of non-Hodgkin's lymphomas.

Study reveals findings on how insulin-producing beta cells grow and function

A new Joslin Diabetes Center-led study has shown conclusively that two receptors in the insulin-producing beta cell do not affect developmental growth, refuting a long-held hypothesis in diabetes research.

New finding provides researchers with renewable source for macrophages and neutrophils

A new approach to generating large quantities of two types of white blood cells that are critical for destroying invading bacteria, viruses and other pathogens in humans has been developed by researchers at the University of California, San Diego (UCSD) School of Medicine.

Potent induction of chondrocytic differentiation of human adipose-derived adult stem cells by bone morphogenetic protein 6

A novel growth factor significantly improves the ability of specialized stem cells derived from human fat to be transformed into cartilage cells, according to Duke University Medical Center and Pratt School of Engineering researchers.

16 Apr 2006

The Notch effect steers stem cells into cells of the nervous system

Stem cell scientists at the University of Edinburgh have discovered that Notch, a protein first discovered more than 80 years ago in the fruit fly, directs unspecialized embryonic stem cells to become cells of the nervous system.

13 Apr 2006

New model of p53 regulation has important implications for the development of anticancer drugs

Genetically engineered mice convinced scientists at the Salk Institute for Biological Studies that it was time to overhaul widely held beliefs about how a powerful tumor suppressor called p53 is controlled in cells. Their new model of p53 regulation has important implications for the development of anticancer drugs.

Targeted mutations in mice uncover two key molecular events linked to learning

Johns Hopkins researchers have used mouse mutants to define critical steps involved in learning basic motor skills. The study focuses on the behavior of two proteins and the specific steps they take to control a neuron's ability to learn by adapting to signals from other nerve cells.
