Scientists learn valuable lesson from nature - secret behind nature's medicines

After years of wondering how organisms managed to create self-medications, such as anti-fungal agents, chemists have discovered the simple secret.

Inhibiting cell process may give cancer drug a boost

A molecule that interferes with the internal scaffolding that shapes the cell may kill cancer cells, retard the growth of tumors and give a boost to a common chemotherapy drug, according to findings appearing in the May 3 issue of the European Journal of Cancer.

An engineered virus that tracks down and compels cancer cells to eat themselves

An engineered virus tracks down and infects the most common and deadly form of brain cancer and then kills tumor cells by forcing them to devour themselves, researchers at The University of Texas M. D. Anderson Cancer Center report.

Elevated serum alanine aminotransferase activity and calculated risk of coronary heart disease in the U.S.

A new study on the relationship between nonalcoholic fatty liver disease (NAFLD) and heart disease found that patients with an elevated level of the enzyme associated with NAFLD had an increased risk of coronary heart disease, which appears to be related to insulin resistance, obesity and central fat distribution.

Environmentally damaged DNA may contribute to human genetic diversity

In this month's issue of the leading scientific journal Genome Research, scientists from Kyushu University report how environmentally damaged DNA may contribute to human genetic diversity.

New drug to treat rare Pompe disease gets FDA approval

The Food and Drug Administration in the U.S. has given approval for the first drug to treat a rare, debilitating muscle disease that can kill infants within a year.

Method by which Caspase-12 shuts down the body's immune system discovered

Caspase-12 is a molecule with a death-wish. Found only in people of African descent, this protein shuts down our body's immune system, opening the door to potentially lethal infections. In a groundbreaking new study published in the prestigious journal Nature this week, the team that first discovered the role of caspase-12 in humans has now uncovered the mechanism by which it sabotages us, allowing researchers to develop methods to counter its damaging effects.

Amyloid protein content in the brain linked to Alzheimer's disease risk

Researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to the University of Antwerp are the first to show that the quantity of amyloid protein in brain cells is a major risk factor for Alzheimer's disease. Amyloid protein has already been known to be the primary component of the senile plaques in the brains of patients. The new discovery demonstrates that the greater the quantity of the protein that is produced, the younger the dementia patient is.

Enzyme discovery could reduce Kaposi sarcoma tumour growth and lead to drugs suitable for treating other viral cancers

A report in the Journal of Biological Chemistry shows that inhibition of heme oxygenase-1, an enzyme involved in iron metabolism, reduces Kaposi sarcoma tumor growth. This discovery could result in the production of new drugs to treat this and other viral cancers.

Study indicates how drug efficacy can be increased by manipulating the signalling mechanism

Researchers believe they have found a way to change the action of 60 percent of currently available medications, in some cases making them many times more effective, according to an article published in the April 21 edition of the journal Science. The discovery has the potential to improve treatments for diseases including heart disease, cancer, diabetes, depression and arthritis. The study describes a new way to manipulate perhaps the most important signaling mechanism in human cells: G-protein coupled receptors (GPCRs).

Finding indicate why some kinds of Leukemia are more aggressive than others

New clues to why some kinds of leukemia are more aggressive and deadly than others are coming from research examining the types of genetic damage that allow some blood cells to grow out of control, scientists report.

Caspase-12 antagonists could potentially be useful in the treatment of sepsis and other inflammatory and immune disorders

According to the new study, the presence of caspase-12, which appears to modulate inflammation and innate immunity in humans, increases the body's "vulnerability to bacterial infection and septic shock" while a deficiency confers strong resistance to sepsis. This new discovery suggests that caspase-12 antagonists could be a potentially useful in the treatment of sepsis and other inflammatory and immune disorders.

Anthrax killed by protein that explodes cell walls

Not all biological weapons are created equal. They are separated into categories A through C, category A biological agents being the scariest: They are easy to spread, kill effectively and call for special actions by the pubic health system. One of these worrisome organisms is anthrax, which has already received its fair share of media attention. But work in Vince Fischetti's laboratory at Rockefeller University suggests that a newly discovered protein could be used to fight anthrax infections and even decontaminate areas in which anthrax spores have been released.

Novel approach used to neutralize anthrax toxin

Researchers from Rensselaer Polytechnic Institute and the University of Toronto have designed a nanoscale assembly of molecules that successfully counteracts and inhibits anthrax toxin in animal and laboratory experiments.

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.

WRN exonuclease structure and molecular mechanism imply an editing role in DNA end processing

A team of scientists from Lawrence Berkeley National Laboratory and the Scripps Research Institute has determined the crystal structure and molecular mechanisms of a key part of WRN, a protein that protects humans from premature aging and cancer.
