Scientists have used a gene therapy tool that acts like intelligent molecular scissors to correct the key gene defect in mice with hemophilia B, a disease that can lead to uncontrolled bleeding. The intervention improved the animals’ blood clotting enough that their severe disease was reduced to a mild form.

A study in mice has pinpointed a pivotal new player in triggering the rapid antidepressant response produced by ketamine. By deactivating a little-known enzyme, the drug takes the brakes off rapid synthesis of a key growth factor thought to lift depression, say researchers supported by the National Institutes of Health.

In a study of mice, researchers have slowed an immune system attack on the ovaries. The mice developed a disorder resembling primary ovarian insufficiency (POI), a menopause-like condition that affects women under the age of 40, sometimes years or even decades before normal menopause.

Mayo Clinic investigators and collaborators from the United Kingdom cured well-established prostate tumors in mice using a human vaccine with no apparent side effects. This novel cancer treatment approach encourages the immune system to rid itself of prostate tumors without assistance from toxic chemotherapies and radiation treatments.

The findings suggest manipulating activity of PKD1, the gene causing the most common form of polycystic kidney disease, may prove beneficial in reducing cysts in both liver and kidney.

Scientists have designed a brain implant that restored lost memory function and strengthened recall of new information in laboratory rats — a crucial first step in the development of so-called neuroprosthetic devices to repair deficits from dementia, stroke and other brain injuries in humans.

Funded by the Defense Advanced Research Projects Agency (DARPA) and spurred by the return of injured Iraq and Afghanistan war veterans, researchers aim to design prostheses that will not only be able to move, but also provide amputees and quadriplegics with a sense of touch.

A study, conducted in baboon primates, finds that when mothers are even moderately undernourished while pregnant and breastfeeding, their offspring are consistently found to be prediabetic before adolescence. It is the first time that diabetes has been shown to have prenatal origins in a primate model.

There is an intimate and complex relationship between inflammation and cancer; and it is well established that tumors secrete many different chemicals that attract host cells which drive inflammation and help to support tumor growth. Now, a new study published by Cell Press in the June issue of the journal Cancer Cell identifies a single protein that is required for trafficking of immune cells involved in inflammation. The research opens up new avenues for therapeutics that can indirectly suppress malignancy by disrupting the inflammatory response.
