Researchers discover naturally occurring growth factor that stimulates regeneration of injured nerve fibers in the central nervous system

Researchers at Children's Hospital Boston have discovered a naturally occurring growth factor that stimulates regeneration of injured nerve fibers (axons) in the central nervous system.

Steroid and xenobiotic receptor and vitamin D receptor crosstalk mediates CYP24 expression and drug-induced osteomalacia

Long-term therapy with some antiepileptic drugs and antibiotics can cause osteomalacia, a condition marked by softening of the bones that is usually the result of vitamin D and calcium deficiency.

Signaling pathways in immune cells may lead to novel HIV treatment

New research on signaling pathways in immune cells bolsters evidence of connections between the central nervous system and the immune system.

Low affinity analogs of thyrotropin-releasing hormone are super-agonists

Chemical knockoffs resembling a key thyroid-related hormone are, in certain cases, more effective than the real thing at activating the target receptor.

First animal model that mimics human head and neck cancer

An Oregon Health & Science University Cancer Institute research laboratory has developed a novel mouse model designed specifically to study the often devastating head and neck squamous cell cancers.

Inhaled corticosteroids can reduce breathing problems in children at high risk for asthma

Studies in older children and adults show that the most effective long-term control medicine for persistent asthma (symptoms more than two days a week or more than twice a month at night) is inhaled corticosteroids, which reduce airway swelling and help prevent asthma symptoms (e.g., asthma attacks).

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.

Long-term estrogen therapy may be related to a higher risk of breast cancer

Previous studies have linked the use of hormone therapy to breast cancer among postmenopausal women, but have primarily focused on the hormone combination of estrogen plus progestin, according to background information in the article.

Novel protein JHDM2A offers new look at male hormone regulation

For the second time in less than a year, University of North Carolina at Chapel Hill scientists have purified a novel protein and have shown it can alter gene activity by reversing a molecular modification previously thought permanent.

Bacterial binding in the stomach

Scientists have determined that decay-accelerating factor (DAF), a protein found in epithelial cells in the stomach, acts as a receptor for the bacteria Helicobacter pylori. Blocking this interaction could lead to new drugs that reduce the risk of peptic ulcer disease or gastric cancer.

Chancroid vaccine may help control HIV in Africa

HIV plagues more than 25 million people in sub-Saharan Africa, according to the World Health Organization, and efforts to develop a vaccine against the virus have achieved limited success.

Therapeutic gene suspected to cause cancer

One of the few gene therapy studies that had ever been successful was terminated in 2003, because several of the treated children had developed leukemia.

Endocannabinoid system shows promise in combating obesity

As the obesity epidemic grows in the United States, the medical community is faced with the significant challenge of properly treating patients before complications such as heart disease arise.

Inflammation markers identify fatigue in breast cancer survivors

Researchers at the University of California, Los Angeles have defined conditions associated with disabling fatigue that persists for years in almost a third of breast cancer survivors, according to a study in the May 1 issue of Clinical Cancer Research.

New drug lixivaptan reduces excess fluid build-up in patients with congestive heart failure

Researchers believe they may have identified a new agent to reduce the excess fluid build-up in patients with congestive heart failure, one that avoids the relative sodium-depleting effects of diuretics, now the most commonly used drugs for this purpose.

Etanercept and chemo might reduce fatigue in cancer patients

Researchers here have found evidence that combining a drug typically used to treat rheumatoid arthritis with chemotherapy might help reduce fatigue and muscle wasting that often afflicts cancer patients.

Lipoxin A4 regulates bronchial epithelial cell responses to acid injury

Doctors are gaining new leverage in the fight against lung injury caused by acid reflux. The paper by Bonnans et al., "Lipoxin A4 regulates bronchial epithelial cell responses to acid injury," appears in the April issue of The American Journal of Pathology and is accompanied by a commentary.

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).
