The regulation of gene expression is mediated by interactions between chromatin and
protein complexes. The importance of where and when these interactions take place in the …

We show that the nuclear architecture of rod photoreceptor cells differs fundamentally in
nocturnal and diurnal mammals. The rods of diurnal retinas possess the conventional …

This article focuses on the role of the interchromatin compartment (IC) in shaping nuclear
landscapes. The IC is connected with nuclear pore complexes (NPCs) and harbors splicing …

The mesencephalic dopaminergic (mesDA) system regulates behavior and movement control
and has been implicated in psychiatric and affective disorders. We have identified a bicoid-…

… The promoter domains are aligned with the diagram in C below. [C) The position of the
known regulatory elements of the rPOMC promoter [ - 480 bp to + 63 bp) is shown. Previously …

… line when introduced in Balb/c mouse blastocysts. All animals analyzed for this work were
hybrid Sv129 × Balb/c of the first three generations of crossing with Balb/c mice. About 50 Ptx1 …

A subfamily of bicoid-related homeodomain factors was recently discovered through its
involvement in transcription of pituitary-specific genes. We isolated the first member of this family, …

… In addition, high Ptx1 expression colocalized with αGSU-expressing cells from the onset
of αGSU expression during pituitary development (C. Lanctôt and J. Drouin, in preparation). …

Fluorescence in situ hybridization (FISH) of specific DNA probes has become a widely used
technique mostly for chromosome analysis and for studies of the chromosomal location of …

Ptx1 is a member of the small bicoid family of homeoboxcontaining genes; it was isolated as
a tissue-restricted transcription factor of the pro-opiomelanocortin gene. Its expression …
