Researchers set a new standard in the design and engineering of nuclear hormone receptor-based genetic on-off switches

Researchers at the University of Illinois at Urbana-Champaign have set a new standard in the design and engineering of nuclear hormone receptor-based genetic on-off switches, without causing new problems or aggravating existing ones.

Why different tissues in the human body vary in their susceptibility to "amyloid" diseases

Researchers at The Scripps Research Institute are reporting the results of a recent study that addresses why different tissues in the human body vary in their susceptibility to "amyloid" diseases, which include Alzheimer's disease and a cluster of ailments called the familial amyloidoses.

Yeast discovery provides new insights into familial dysautonomia

A discovery in yeast that has important implications for finding a cure for a devastating disease of nerve cell failures -- called familial dysautonomia (FD) -- has been made by Cornell University researchers.

Promising new therapy that prompts the immune system to aid in the fight against melanoma tumors

Melanoma is a particularly deadly form of skin cancer very resistant to treatment. Researchers at H. Lee Moffitt Cancer Center & Research Institute and the University of South Florida are testing a promising new therapy that prompts the immune system to aid in the fight against melanoma tumors.

Pair of cancer genes found to drive both cell migration and division

Johns Hopkins researchers have found that two genes already known to control cell movement are also needed for proper cell division. They report their findings in the April issue of Developmental Cell.

An exceptionally effective lead-detection protein

Scientists from the U.S. Department of Energy’s Brookhaven National Laboratory and the University of Chicago have discovered that a member of a well-known protein family is better at detecting lead than any other known substance.

Immune cells in the liver travel in the liver's blood vessels with surprising speed and agility

Scientists at New York University School of Medicine viewing the actual journey of immune cells in the liver have found that these cells travel in the liver's blood vessels with surprising speed and agility.

Step toward a potential treatment for Huntington's disease

Researchers at the University of Iowa Roy J. and Lucille A. Carver College of Medicine have taken another step toward a potential treatment for Huntington's disease (HD). Using an approach called RNA interference (RNAi), the scientists reduced levels of the disease-causing HD protein in mice and significantly improved the movement and neurological abnormalities normally associated with the disease.

Potential therapeutic role for the ataxin-3 protein for Machado-Joseph disease

The repetition of three little "letters" within the gene that codes for the ataxin-3 protein is both the cause of and perhaps a solution to Machado-Joseph disease and an entire family of similar genetic disorders, according to researchers at the University of Pennsylvania.

New miniature sensors for analysing DNA

The sensors have the same size and thickness as a fingernail and reduce the time needed to identify DNA chains to several minutes or a few hours, depending on each chain.

Could NAADP/cholecystokinin-combo attack fat from inside and out?

One traditional approach to pharmaceutical design uses so-called “first messengers” – hormones, other natural facilitators or synthetic products – to initiate various cellular cascades for the desired physiological effect. To date, despite concerted efforts at all levels of research, this approach has failed to develop a truly successful obesity drug to address this major global health problem.

Discovery of the enzyme that destroys cartilage in inflammatory arthritis

A Melbourne-led team of scientists has discovered the enzyme that destroys cartilage in inflammatory arthritis, offering new hope to sufferers of this painful condition.

Discovery of missing enzyme for tuberculosis iron scavenging pathway

Scientists have discovered that a protein that was originally believed to be involved in tuberculosis antibiotic resistance is actually a "missing enzyme" from the biosynthetic pathway for an agent used by the bacteria to scavenge iron.

Urine actually helps a particular yeast stick to cells along the urinary tract

The finding might offer a new way to prevent or treat certain yeast and fungal infections, and the researchers' work also provides an unexpected new role for some proteins already known to help hungry yeast live longer.

Medication that both stimulates appetite and reduces metabolic rate

Scientists at Oregon Health & Science University, in collaboration with Neurocrine Biosciences Inc., have successfully tested a research medication that both stimulates appetite and reduces metabolic rate in preclinical trials.

New color-coded test for protein folding

Every protein--from albumin to testosterone--is folded into a unique, three-dimensional shape that allows it to function properly. Now Stanford University scientists have developed a simple test that instantly changes color when a protein molecule attached to a gold nanoparticle folds or unfolds.

Gene/yeast finding links processes in heart disease and cancer

By studying a little-known yeast too primitive to get diseases, Johns Hopkins researchers have uncovered a surprising link between two processes at play in heart disease and cancer in people.

Molecule that causes secondary stroke

Scientists at the University of Cincinnati (UC) College of Medicine have discovered the cause of a deadly type of secondary stroke known as cerebral vasospasm.

New therapy for treating cat allergies looks promising

Andrew Saxon, M.D., and a team of researchers at University of California, Los Angeles (UCLA) have found that a molecule designed to block cat allergies can prevent allergic reactions in laboratory mice and was also successful when tested on human cells in a test tube.

New directions toward the treatment of bipolar disorder

While lithium treatment has proven to be a godsend for many of the two million Americans with bipolar disorder, it is not without its downside. People on the drug may develop hypothyroidism, tremors, cognitive impairment, and excessive thirst and urination and gain weight.
