Increased 5-hydroxymethylcytosine (5hmC) at the glutamic acid decarboxylase 67 (GAD67) promoter in psychotic (PSY) patients. Binding of 5-methylcytosine (5mC) (a) and 5hmC (b) to GAD67 promoter was measured by immunoprecipitation using specific 5hmC and 5mC antibodies with previously published procedures.4 We find significantly increased 5hmC, but not 5mC, in PSY patients () compared with nonpsychiatric (CTR) subjects (□) at both regions of the GAD67 promoter examined. *P<0.05 vs CTR; **P<0.01 vs CTR.
