A new, less toxic way to treat malignant melanoma

A new, less toxic way to treat malignant melanoma (skin cancer) is being developed by medicinal chemists at Reading University. They have produced a range of prodrugs: compounds that offer the potential to be converted to toxic molecules only within the vicinity of tumours. These prodrugs aim to reduce the toxicity of treatment.

Scientists reverse memory loss in mice with Alzheimer's

In mice, that had been genetically engineered to develop Alzheimer's disease, scientists were able to reverse the rodents' memory loss by reducing the amount of an enzyme that is crucial for the development of Alzheimer's disease.

"Designer" rats help show how declining estrogen after menopause can affect hypertension

Scientists at Wake Forest University School of Medicine have created a better research rat – the first to enable them to study how declining estrogen after menopause can affect hypertension, heart failure and kidney damage.

Notch1 and Jagged1 genes are likely markers indicating a patient's probable aggressive breast cancer

In a new study, scientists at The Hospital for Sick Children and Princess Margaret Hospital have shown that two genes called Notch1 and Jagged1 are linked to more aggressive breast cancers and that patients are less likely to survive the disease when these two genes are highly expressed.

Neurologix announces positive interim results of gene therapy clinical trial for patients with Parkinson's disease

Neurologix has announced positive interim results of its landmark gene therapy clinical trial for patients with Parkinson's disease. Neurologix's 12-patient, dose-escalating Phase I trial is the world's first study to use a viral vector (the non-pathogenic adeno-associated virus, or AAV) for the treatment of an adult neurological disease.

Raf Kinase Inhibitor Protein plays a role in controlling the active movement of cells

University of Illinois at Chicago researchers report that a protein that regulates key signaling pathways in cells also plays a role in controlling the active movement or migration of cells. The finding may suggest new pharmaceutical therapies for treating a variety of diseases, including cancer.

Study clarifies insulin's role in blocking release of energy in patients with type II diabetes

Chronically high levels of insulin, as is found in many people with obesity and Type II diabetes, may block specific hormones that trigger energy release into the body, according to researchers at the University of California, San Diego (UCSD) School of Medicine.

22 biomarkers that provide a more accurate screening for prostate

Researchers at the University of Michigan Comprehensive Cancer Center have identified a panel of 22 biomarkers that together provide a more accurate screening for prostate cancer than the current prostate specific antigen, or PSA, test.

Simple organism can produce 10 trillion varieties of a single protein

A team led by University of California, San Diego biochemists has discovered the mechanism by which a simple organism can produce 10 trillion varieties of a single protein, a finding that provides a new tool to develop novel drugs.

Antibiotic resistance has put humans in an escalating 'arms race' with infectious bacteria

...as scientists try to develop new antibiotics faster than the bacteria can evolve new resistance strategies. But now, researchers have a new strategy that may give them a leg up in the race -- reproducing in the lab the natural evolution of the bacterial enzymes that confer resistance.

Key neural system at risk from prenatal exposure to alcohol

In a study of adult monkeys who were exposed to moderate amounts of alcohol in utero, scientists have found that prenatal exposure to alcohol - even in small doses - has pronounced effects on the development and function later in life of the brain's dopamine system, a critical component of the central nervous system that regulates many regions of the brain.

O-GlcNAc sugar is a critical regulator of cells' natural life cycle

The discovery reveals that, when disturbed, this process could contribute to cancer or other diseases by failing to properly control the steps and timing of cell division, the researchers say. The findings are described in the Sept. 23 issue of the Journal of Biological Chemistry, available online now.

Low-dose aspirin might prevent the cardiovascular damage known to arise from use of the painkiller rofecoxib (Vioxx)

Their findings that a chemical imbalance might underlie such damage could also lead to the development of anti-inflammatory drugs without the adverse side effects, the researchers said.

PUMA protein offers critical insights for developing new anti-cancer drugs

The discovery of how the activities of the protein p53 initiate signals that trigger cell suicide offers critical insights for developing new anti-cancer drugs, according to investigators from St. Jude Children's Research Hospital.

Possible new target for treating obesity and diabetes

The new target, a molecule called hVps34, is activated by amino acids (nutrients) entering the cell. This molecule triggers the activation of an enzyme, S6 Kinase 1 (S6K1), whose function UC researchers linked last year to obesity and insulin resistance.

Scientists have discovered a new and potent anti-cancer compound in beans

Scientists have discovered a new and potent anti-cancer compound in everyday food. The collaborative study led by UCL (University College London) shows that the compound - inositol pentakisphosphate - found in beans, nuts and cereals inhibits a key enzyme (phosphoinositide 3-kinase) involved in tumour growth.
