Abstract
Five adenosines within the coding sequence of the serotonin 2C receptor (5-HT2C) pre-mRNA are converted to inosines by RNA editing (named A, B, C' (E), C, and D sites). In human prefrontal cortex (PFC), the most abundant 5-HT2C mRNA sequences result from editing at the A site, or from the editing combinations AC'C, ABCD, and ABD. In suicide victims with a history of major depression, C' site editing is significantly increased, D site editing is significantly decreased, and the C site shows a trend toward increased editing. Treatment of mice with the antidepressant drug fluoxetine (Prozac) causes changes in C', C, and D site editing that are exactly opposite to those seen in suicide victims. Thus, one outcome of fluoxetine treatment may be to reverse the abnormalities in 5-HT2C pre-mRNA editing seen in depressed suicide victims.
