Examination of the expression of molecules in the Notch signaling pathway in the forebrain of mice for all treatment groups (n=6 for each group). (A-B) RT-PCR showed no change of Notch2 (F 3, 25=0.323, P=.809), and Notch4 levels (F 3, 18 = 0.708, P=.56) in each group. (C-E) RT-PCR results demonstrated that Notch1, Hes1, and Hes5 were upregulated by quetiapine and downregulated by cuprizone. Notch1 (C) (F 3, 24 = 8.335, P<.01), Hes1 (D) (F 3, 22 = 8.637, P<.01), and Hes5 (E) (F 3, 24 = 4.478, P<.05) all increased in the cuprizone/quetiapine cotreatment group. (F-H) Western-blot analysis showed decreased expressions of Hes1 (F 3,22=7.498, P<.01), and Hes5 (F 3, 22=10.335, P<.01) in CPZ group and were upregulated after quetiapine co-administration. *P<.05, **P<.01.
