Modeling schizophrenia in flies

Abstract

Schizophrenia is a debilitating mental illness that affects 1% of the population worldwide. Although its molecular etiology remains unclear, recent advances in human psychiatric genetics have identified a large number of candidate genetic risk factors involved in schizophrenia. Modeling the disease in genetically tractable animals is thus a challenging but increasingly important task. In this review, I discuss the potential problems and perspectives associated with modeling schizophrenia in fruit flies, and briefly review the recent studies analyzing the molecular and cellular functions of Disrupted-In-Schizophrenia-1 (DISC1) in transgenic flies.
