The impact of treatment of lithium and olanzapine on glycogen synthase kinase-3 activity in the peripheral blood mononuclear cells of patients with bipolar mania

Objective：To explore the impact of treatment of lithium and olanzapine on glycogen synthase kinase-3（GSK3） activity in the peripheral blood mononuclear cells（PBMCs） of patients with bipolar mania. Method：21 patients with bipolar I mania were enrolled and received treatment of lithium and olanzapine for eight weeks.20 ml of blood was collected from each patient by venipuncture at week 0,week 4 and week 8.The level of pSer21-GSK3α,pSer9-GSK3β,total GSK3α and GSK3β in PBMCs of patients were measured by western blot when blood samples of three visits were collected.Clinical symptoms were assessed with the Young mania rating scale（YMRS） ,the Montgomery-Asberg depression rating scale（MADRS） and the clinical global impression for bipolar disorder-severity（CGI-S） at the same time. Results：①The average scores of YMRS,MADRS,and CGI-S significantly reduced at week 8 compared with those at week 0（P0.001）;②The level of pSer-GSK3α and pSer-GSK3β increased at week 8.The increase was especially apparent in pSer-GSK3β from（53.44±17.57） at week 0 to（72.96±25.66） at week 8;Excluding patients with manic episodes more than 3 times,there is a significant increase in pSer-GSK3β during the eight-week treatment（P=0.022）;③There was a negative correlation between ratio of pSer-GSK3β to total-GSK3β and the average score of YMRS at week 0（r= -0.-487,P=0.025） . Conclusion：Lithium and olanzapine could increase the level of pSer-GSK3β in PBMCs of patients with bipolar mania and decrease GSK3 activity.
