KLF4 and schizophrenia: BIX was able to significantly upregulate IL-6 mRNA (control: F2,69 = 17.2, p<0.001; schizophrenia: F2,69 = 19.4, p<0.001; Fig 2A), GAD67 mRNA (control: F2,69 = 56.2, p<0.001, schizophrenia: F2,69 = 75.1, p<0.001; Fig 2B), NANOG mRNA (control: F2,69 = 11.27, p<0.001, schizophrenia: F2,69 = 38.4, p<0.001; Fig 2C) and KLF4 mRNA (control: F2,69 = 494.6, p<0.001, schizophrenia, F2,69 = 60.9, p<0.001; Fig 2D) in both diagnostic groups.
