TCF4 and schizophrenia: No significant differences were detected in the mRNA expression of IQGAP1 (F(1, 38) = 1.16, p = 0.29), CTNNβ1 (F(1, 38) = 0.17, p = 0.68), GSK3β (F(1, 38) = 0.26, p = 0.61), FOXO1 (F(1, 38) = 1.93, p = 0.17), LRP6 (F(1, 38) = 0.29, p = 0.59), MGEA5 (F(1, 38) = 0.64, p = 0.43), TCF4 (F(1, 38) = 0.34, p = 0.56), βTRC (F(1, 37) = 0.01, p = 0.92), PPP1Cβ (F(1, 38) = 0.52, p = 0.46), or DVL2 (F(1, 38) = 1.27, p = 0.27) in DLPFC tissue between the schizophrenia and non-psychiatrically ill control cohorts.
