Scientists identify gene responsible for one type of Charcot-Marie-Tooth disorder

Scientists have identified the gene responsible for one type of Charcot-Marie-Tooth disorder, a common inherited neurological disease, thanks to the chance appearance of a strain of impaired 'pale tremor' mice in a University of Michigan research laboratory.

DNA repair by Brca2 prevents medulloblastoma

St. Jude investigators have gained some of the first major insights into how certain genes known to prevent cancer also guide the nervous system's normal development before birth and during infancy by repairing DNA damage.

New understanding of modern pandemic infection

Human resistance to a retrovirus that infected chimpanzees and other nonhuman primates 4 million years ago ironically may be at least partially responsible for the susceptibility of humans to HIV infection today.

New treatment slows the growth of colon and liver cancers

A. Navarro, a researcher at the School of Pharmacy of the University of Navarra, has developed a new treatment which slows the growth of colon and liver cancers.

RNA polymerase points to new targets for drug design

Researchers at UAB (University of Alabama at Birmingham) have new information on the structure of a key enzyme in bacteria that could lead to improved antibiotics and less antibiotic resistance.

Goltz syndrome gene found

Researchers funded in part by the National Institutes of Health have identified the gene that accounts for most cases of Goltz syndrome, a rare skin disorder that can also affect bone and eye development.

Entecavir can compromise HIV treatment

Treating hepatitis B patients with the drug entecavir can cause those who are also infected with HIV to become resistant to two of the most important drugs in the anti-HIV arsenal, according to a new report in the New England Journal of Medicine.

Smoking affects ligament healing

The list of reasons you shouldn't smoke has gotten longer. Researchers at Washington University School of Medicine in St. Louis are reporting that smoking interferes with ligament healing.

Autism-related proteins control nerve excitability

Two proteins that are implicated in autism have been found to control the strength and balance of nerve-cell connections, researchers at UT Southwestern Medical Center have found.

New way to increase stem cells in blood

Researchers at Children's Hospital Boston report finding a new way to increase stem cells in blood, suggesting a possible treatment to help patients who undergo chemotherapy or bone marrow transplant for leukemia and other cancers recover their immune function more quickly.

Size of family appears to affect breast cancer risk

Researchers have found that the probability of the breast cancer gene mutation BRCA among women with a history of breast cancer is greater when the number of older, female relatives in the family is smaller, according to a study in the June 20 issue of JAMA: The Journal of the American Medical Association.

Master regulator of the stem cell state

For more than 25 years, stem cells have been defined based on what they can become: more of themselves, as well as multiple different specialized cell types.

Gene test not needed if cancer drug irinotecan given in low dose

Investigators at St. Jude Children's Research Hospital have shown that when the cancer drug irinotecan is given in low doses for multiple days, it eliminates the need to delay treatment to perform costly genetic testing that determines if the patient is at risk for serious treatment side effects, such as neutropenia.

Scientists develop unique “switch” that can control the activity of any protein

Our bodies could not maintain their existence without thousands of proteins performing myriad vital tasks within cells. Since malfunctioning proteins can cause disease, the study of protein structure and function can lead to the development of drugs and treatments for numerous disorders.

Resistant gut bacteria will not go away by themselves

E. coli bacteria that have developed resistance to antibiotics will probably still be around even if we stop using antibiotics, as these strains have the same good chance as other bacteria of continuing to colonise the gut, according to a thesis at the Sahlgrenska Academy.

New molecular mechanism discovered that may 'spontaneously' cause liver cancer

Adding more good news to last week's announcement that Nexavar (sorafenib) may be the first effective treatment for advanced liver cancer, researchers at the Lombardi Comprehensive Cancer Center at Georgetown University have uncovered a new molecular mechanism that may 'spontaneously' cause liver cancer.
