GSK3B and schizophrenia: Despite the critical roles of WNT signaling in neurodevelopment and synaptic plasticity, our findings revealed no significant changes between schizophrenia and non-psychiatrically ill cohorts in the region-level mRNA expression of the 10 WNT signaling genes studied: IQGAP1, CTNNB1, GSK3β, FOXO1, LRP6, MGEA5, TCF4, βTRC, PPP1Cβ, and DVL2.
