Jumping DNA:Cause of Schizophrenia?

Retrotransposons are short sequences of DNA that autonomously amplify and move around the genome. One class of retrotransposons named Long Interspersed Nuclear Elements (LINE) make up a large part of the eukaryotic genome and it is believed that they may contribute to a number of disorders and diseases such as cancer and schizophrenia. In a study published, a Japanese team revealed that LINE-1 retrotransposons are abnormally abundant in the schizophrenia brain, modify the expression of genes related to schizophrenia during brain development, and may be one of the causes of schizophrenia. LINE-1 have been shown to be more abundant in brain cells than in other cells in the body in adults, providing evidence for enhanced activity of LINE-1 in the human brain. However, the role played by LINE-1 in mental disorders, and in particular schizophrenia, has remained unclear.

 

New Scope: However, this study proposes a brand new mechanism of pathophysiology of schizophrenia. Previously, schizophrenia was regarded as a disease caused by gene-environment interactions, but our study shows that the environment can alter the genome and may contribute to the disease.
