Small molecule nutlin-3a activates an important cancer suppressor gene

By activating a cancer suppressor gene, a small molecule called nutlin-3a can block cancer cell division, according to researchers at the National Cancer Institute (NCI), part of the National Institutes of Health.

Early treatment of Helicobacter pylori infection may prevent cancer

Based on research using a new mouse model of gastritis and stomach cancer, researchers from the Massachusetts Institute of Technology (MIT) say that prompt treatment of Helicobacter pylori (H. pylori) infections reverses damage to the lining of the stomach that can lead to cancer.

New drug added to chemo kills off residual breast cancer stem cells

New research says chemotherapy often fails to totally eliminate breast cancer because it does not knock out breast cancer stem cells.

Alzheimer's disease risk differs between the sexes

The risks of developing Alzheimer's disease differ between the sexes, with stroke in men, and depression in women, critical factors, suggests research published ahead of print in the Journal of Neurology Neurosurgery and Psychiatry.

Turning on cell-cell communication wipes out staph biofilms

University of Iowa researchers have succeeded in wiping out established biofilms of Staphylococcus aureus (staph) by hijacking one of the bacteria's own regulatory systems.

New understanding of how some bacteria survive antibiotic treatment

Researchers at the University of Illinois at Chicago have discovered how some bacteria can survive antibiotic treatment by turning on resistance mechanisms when exposed to the drugs.

Researchers create heart and blood cells from reprogrammed skin cells

Stem cell researchers at UCLA were able to grow functioning cardiac cells using mouse skin cells that had been reprogrammed into cells with the same unlimited properties as embryonic stem cells.

Scientists discover the double life of proteins

Scientists at The Australian National University are a step closer to understanding the rare Hartnup disorder after discovering a surprising link between blood pressure regulation and nutrition that could also help to shed light on intestinal and kidney function.

Researchers discover molecular basis of limb-girdle muscular dystrophy

A team of French and German researchers report in the May 2008 print issue of The FASEB Journal that people with limb-girdle muscular dystrophy are missing a protein called c-FLIP, which the body uses to prevent the loss of muscle tissue.

Mothers and offspring can share cells throughout life - with positive and negative effects

Cutting the umbilical cord doesn't necessarily sever the physical link between mother and child. Many cells pass back and forth between the mother and fetus during pregnancy and can be detected in the tissues and organs of both even decades later. This mixing of cells from two genetically distinct individuals is called microchimerism. The phenomenon is the focus of an increasing number of scientists who wonder what role these cells play in the body.

Discovery of quick method for making human monoclonal antibodies against flu

Human monoclonal antibodies (mAbs) - highly specific, identical, infection-fighting proteins produced in large quantities in the lab in cell lines that are derived from a single antibody-producing cell - against influenza can be rapidly produced in the lab, according to a new report from scientists supported by the National Institutes of Health (NIH).

Yale scientists explain metastasis

Metastasis, the spread of cancer throughout the body, can be explained by the fusion of a cancer cell with a white blood cell in the original tumor, according to Yale School of Medicine researchers, who say that this single event can set the stage for cancer's migration to other parts of the body.

Review of cervical cancer screening program shows effectiveness and room for improvement

Women who do not undergo regular cervical cancer screening tests are more likely to be diagnosed with the disease than those who do, according to an audit of the Swedish national cervical cancer screening program that will be published online April 29 in the Journal of the National Cancer Institute.

Hydrogen sulphide may be involved in regulating blood pressure

Hydrogen sulphide is a gas most commonly associated with the smell of stink bombs, sewage and rotten eggs, but a team of researchers from the Peninsula Medical School in the South West of England and King's College London have now identified a role for this gas in regulating blood pressure, according to research published in the leading science journal "Circulation".

Aspirin-like compounds (salicylates) increase insulin secretion in otherwise healthy obese people

Aspirin-like compounds (salicylates) can claim another health benefit: increasing the amount of insulin produced by otherwise healthy obese people. Obesity is associated with insulin resistance, the first step toward type 2 diabetes.

Biomarkers identified for idiopathic pulmonary fibrosis

The first evidence of a distinctive protein signature that could help to transform the diagnosis and improve the monitoring of the devastating lung disease idiopathic pulmonary fibrosis (IPF) is being reported by University of Pittsburgh School of Medicine researchers in this month's edition of PLoS Medicine, an open-access journal of the Public Library of Science.

African Americans have five times higher rate of lower limb amputations

The overall amputation rate in northern Illinois is declining due to improved care for diabetes and peripheral vascular disease, new research shows.

Abmormal behaviour of osteoglycin gene linked to heart and kidney problems

A gene that can cause the heart to become enlarged, greatly increasing the risk of heart attacks and heart failure, is identified today in a new study.

New drug discovery tool for Alzheimer's disease

An article published in the April issue of the Journal of Alzheimer's Disease presents a detailed characterization of a new drug discovery tool for Alzheimer's disease.

Tissue-specific blood stem cell line established from embryonic stem cells

A research team at the Umea Center for Molecular Medicine (UCMM) in Sweden, led by Professor Leif Carlsson, has managed to specifically establish and isolate the tissue-specific stem cell that produces blood cells (blood stem cell) by using genetically modified embryonic stem cells.
