Tectum Development Signaling Model

Model for a possible cooperation of Meis2, Pax3, Pax7 and Otx2during tectal development.

• MHB - mid-hindbrain boundary

Red lines indicate negative regulation, green arrows positive regulation. Dashed lines indicate hypothetical direct regulation of the Meis2 promoter/enhancer by different Pax3 concentrations. Solid lines indicate indirect regulation of Meis2 expression via Pax3/7 mediated induction of Fgf8 as previously reported:

1. Regulation of Meis2 expression in response to Ras-MAPK signaling levels reported in [19];
2. Induction of Fgf8 by Pax3 and Pax7 reported in [11];
3. Existence of Meis2-Otx2 containing protein complexes in the tectal anlage reported in [17].
