DISC1 knockdown reduces mIPSC amplitude and GABAAR current density in cultured cortical pyramidal neurons.
A, cumulative plots of mIPSC amplitudes in neurons transfected with control shRNA, DISC1 shRNA, or DISC1 shRNA plus an shRNA-resistant full-length DISC1 (DISC1R). Note that DISC1 knockdown caused a leftward shift in the distribution of mIPSC amplitudes, indicative of a reduction of mIPSC sizes. B, representative mIPSC traces taken from neurons in A. C, summary (mean ± S.E.) of mIPSC amplitudes and frequencies in neurons with different transfections. **, p < 0.01; Dunnett test. con, control. D, representative whole-cell GABAAR current traces in neurons transfected with control or DISC1 shRNA. E, summary (mean ± S.E.) of GABAAR current density in neurons with different transfections. *, p < 0.05, Student's t test.
