Unlocking schizophrenia biology via genetics

Schizophrenia genetics and its complexities are beginning to yield to large genome-wide studies. One of the recently identified top risk loci, miR 137, can be seen as a master key that unlocks other doors. The Mir 137 locus encodes a micro RNA that regulated hundreds of other genes, and several of those are also linked to schizophrenia.

In early July, Emory’s chair of cell biology Gary Bassell and former graduate student Kristen Thomas published a paper in Cell Reports analyzing how perturbing Mir 137 affects signaling in neurons. Inhibiting Mir 137 blocked neurons’ responses to neuregulin and BDNF, well-known growth factors. Dr. Bassell is a faculty member in the BCDB and NS programs. Dr. Thomas is now a postdoctoral fellow at St Jude Children’s Research Hospital.
