Mutation screening of PAX6 gene helped in identifying a novel heterozygous pathogenic variation g. 31801757dupG (c. 216-19dupG) that resulted in a frameshift mutation that extended into exon 7.
it was suggested that miR-19, upregulated in osteosarcoma cells, negatively regulated the expression of Pax6, which can promote the malignant phenotypes of osteosarcoma cells via activation of the extracellular signal-regulated kinase signaling pathways
Molecular genetic defects involving PAX6 were identified in 30 participants (91%), including 4 novel PAX6 mutations (Gly18Val; Ser65ProfsX14; Met337ArgfsX18; Ser321CysfsX34) and 4 novel chromosome 11p deletions inclusive of PAX6 or a known PAX6 regulatory region.

Pax6 depletion has no effect on the adult mouse corneal epithelium.
Tgfbeta2, Bmp4 and Foxc1 are direct downstream targets of Pax6 in the developing iris.
a novel regulatory relationship between the retinal pigmented epithelium (RPE) transcription factors Pax6 and Sox9 that controls the timing of RPE differentiation and the adjacent choroid maturation, is reported.
PAX6 can substitute for LHX2 and override NFIA-induced astrogliogenesis in developing hippocampus in vivo.
these results not only reveal a novel function for LHX2 in regulating dorsoventral patterning in the telencephalon, but also identify PAX6 as a fundamental regulator of where the hem can form, and therefore implicate this molecule as a determinant of hippocampal positioning.
Comparative functional analyses revealed that the neurogenic function of Pax6 is highly conserved in the developing mouse and chick pallium, whereas stage-specific binary functions of Pax6 in neurogenesis are unique to mouse neuronal progenitors, consistent with Pax6-dependent temporal regulation of Notch signaling. Pax6-dependent enhancer activity of Dbx1 is extensively conserved between mammals and chick.
These results demonstrate a novel role for Tlx3 and indicate that Pax6-Tlx3 expression and interaction is part of a region specific regulatory network in cerebellum and its deregulation during development could possibly lead to Autistic spectral disorders (ASD).

Pax6 normally represses Cdca7 expression in the lateral cortex and that repression of Cdca7 in cells of this region is required for their production of a normal complement of Tbr2-expressing intermediate progenitors
this Pax6 (fl) allele provides a useful addition to the existing Pax6 allelic series and this study demonstrates the utility of using compound heterozygotes with null alleles to unmask cryptic effects of floxed alleles.

Together, the authors show the antagonistic regulation of the alpha-enhancer activity by Pax6 and the LIM protein complex is necessary for the establishment of an inner retinal circuitry, which controls visual adaptation.
reduced expression of PAX6 in metabolically stressed beta cells may contribute to beta cell failure and alpha cell dysfunction in diabetes.
The expression of Barhl2 in the thalamus and pretectum is related to, and regulated by, the expression of Pax6. Pax6 is known to be required for normal diencephalic development. The findings suggest that some of its actions might be mediated by its maintenance of a repressive influence over Barhl2 expression in the thalamus and pretectum.

Study finds that Pax6 is initially distributed contiguously throughout a large domain of the anterior neural plate of zebrafish, including the presumptive eye fields and the dorsal diencephalon.

Pax6 interacts with itself via both the paired domain and the homeodomain. Pax6 interaction with itself superactivates Pax6 mediated transactivation.
This gene encodes paired box gene 6, one of many human homologs of the Drosophila melanogaster gene prd. In addition to the hallmark feature of this gene family, a conserved paired box domain, the encoded protein also contains a homeo box domain. Both domains are known to bind DNA and function as regulators of gene transcription. This gene is expressed in the developing nervous system, and in developing eyes. Mutations in this gene are known to cause ocular disorders such as aniridia and Peter's anomaly. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
