Mayo Clinic researchers and colleagues at the University of California San Francisco (UCSF) have found a connection between DNA alterations on human chromosome 9 and aggressive brain cancer known as glioblastoma. The findings are reported in the current online issue of Nature Genetics.

Using zebrafish, researchers at the University of Pittsburgh have identified and described an enzyme inhibitor that allows them to increase the number of cardiac progenitor cells and therefore influence the size of the developing heart. The findings are described in the advance online version of Nature Chemical Biology.
