In cochlear development, the Notch signaling pathway is required for both the early prosensory phase and a later lateral inhibition phase. While it is known that Hes genes are important downstream mediators of Notch function in lateral inhibition, it is not known what genes function as mediators of the early prosensory function of Notch. We report that two members of the Hes-related gene family...
The embryonic vertebrate heart tube develops an atrioventricular canal that divides the atrial and ventricular chambers, forms atrioventricular conduction tissue and organizes valve development. Here we assess the transcriptional mechanism underlying this localized differentiation process. We show that atrioventricular canal-specific enhancers are GATA-binding site-dependent and act as switches...
We have identified a novel subfamily of mammalian hairy/Enhancer of split (E(spl))-related basic helix-loop-helix (bHLH) genes together with a putative Drosophila homologue. While hairy/E(spl) proteins are characterized by an invariant proline residue in the basic domain and a carboxyterminal groucho-binding WRPW motif, our genes encode a carboxyterminal KPYRPWG sequence and were thus designate...
Regulation of MMP10 expression by the transcription factor CHF1/Hey2 is mediated by multiple E boxes
The Notch signaling is an evolutionarily conserved cell-cell communication pathway that plays critical roles in the proliferation, survival, apoptosis, and fate determination of mammalian cells. Retinal pigment epithelial (RPE) cells are responsible for supporting the function of the neural retina and maintaining vision. This study investigated the function of Notch signaling in RPE cells. We f...
BACKGROUND Vasculogenesis, the de novo formation of blood vessels from precursor cells is critical for a developing embryo. However, the signals and events that dictate the formation of primary axial vessels remain poorly understood. METHODOLOGY/PRINCIPAL FINDINGS In this study, we use ets-related protein-1 (etsrp), which is essential for vascular development, to analyze the early stages of v...
