Pax6 regulates neuronal migration and cell proliferation via interacting with Wnt3a during cortical development.

ABSTRACT: The paired box 6 (Pax6) gene encodes a highly conserved transcription factor, involved in the development of eyes, brain, and endocrine glands. Homozygous loss of Pax6 resulted in neonatal death in mice, plus loss of eyes and malformation of cerebral cortex. In patients with heterozygous Pax6 mutations, a reduction in thickness of the frontoparietal cortex was detected, which was also observed in small eye mice. In this study, we found that Pax6 overexpression increased the cortical thickness, especially in the intermediate zone of the cortex, which conflicts with the report of Manuel et al. Pax6 overexpression appears to detain neurons in the intermediate zone while promoting cell proliferation. It is worth noting that the impact of Pax6 overexpression on cortical thickness and neuronal m
