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.

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.

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.
