Expression of a medaka (Oryzias latipes) Bar homologue in the differentiating central nervous system and retina

Mech Dev. 2002 Jun;114(1-2):193-6. doi: 10.1016/s0925-4773(02)00054-0.

Abstract

The Bar homeobox genes play an essential role during nervous system and eye development in Drosophila. We isolated a medaka Bar gene closely related to the Drosophila and mammalian Bar genes. In the medaka embryo, OlBar is expressed from gastrula stages onwards, in a region demarcating the presumptive prosencephalic-mesencephalic boundary. Later in development, OlBar transcripts are found in populations of differentiating neuronal cells of the brain and the retina.
