New study in 'Nature' demonstrates protection against cell death during heart attack
... says Dr. Molkentin. "Although our study was in a mouse
model and looked at the heart, studies in cell culture indicate similar benefits when blood flow causes injury to the brain, kidney and liver. The data support clinical trials. Cyclosporin already has been tested in humans and has been well-tolerat...

A marker for new blood vessel formation in tumors
...metastasize. Haubner and colleagues' work, in a mouse
with human melanoma and in a small study of patients with tumors including melanoma, suggests that the marker is truly reflecting the in vivo level of the integrin. Hence the marker could be used to identify tumors that express this marker, assess th...
Indiana University researchers closer to helping hearing-impaired using stem cells

marrow stromal cells with chemicals known to encourage stems cells to change into primitive neurons. The bone marrow cells took the shape and other characteristics of neurons. Next, they exposed the cells to two molecules that are secreted from nearb...
First mouse model for multiple system atrophy points to new treatment targets for brain diseases

Targeting mutant B-Raf protein reduces melanoma development
...t, reducing B-Raf activity in existing tumors in a mouse
model did not shrink the tumors but did prevent them from getting bigger. These discoveries are important for the treatment of metastatic melanoma since therapeutically inhibiting mutant B-Raf could prevent growth of existing tumors and more importan...
