Objective(s): NOTCH signaling pathway is well known for its role in cell fate, cell survival, cell differentiation, and apoptosis. Some of the NOTCH signaling genes are critical for endometrial function and implantation in animals and appear to play a similar role in humans. The purpose of the current study was to investigate the potential roles of some main components of the NOTCH family in hu...

Background: Differentiating oligodendrocyte precursor cells (OPCs) into oligodendrocytes could be improved by inhibiting signaling pathways such as Wnt and Notch. 9-cis-retinoic acid (9-cis-RA) and 1,25-dihydroxyvitamin D3 (1,25[OH]2D3) can ameliorate oligodendrogenesis. We investigated whether they could increase oligodendrogenesis by inhibiting the Wnt and Notch signaling pathways.Methods: Co...

Notch signaling inhibits hair cell differentiation, based on studies on mice deficient in Notch signaling-related genes and its downstream genes. However, the precise mechanisms of this inhibition are unknown because it is difficult to control the timing and duration of the suppression of Notch signaling. Here, we developed a novel in vitro culture and analysis method for mouse fetal cochleae a...

BACKGROUND In the vasculature, Notch signaling functions as a downstream effecter of Vascular Endothelial Growth Factor (VEGF) signaling. VEGF regulates sprouting angiogenesis in part by inducing and activating matrix metalloproteases (MMPs). This study sought to determine if VEGF regulation of MMPs was mediated via Notch signaling and to determine how Notch regulation of MMPs influenced endoth...

Notch receptor signaling regulates cell growth and differentiation, and core components of Notch signaling pathways are conserved from Drosophila to humans. Fringe glycosyltransferases are crucial modulators of Notch signaling that act on epidermal growth factor (EGF)-like repeats in the Notch receptor extracellular domain. The substrate of Fringe is EGF-O-fucose and the transfer of fucose to N...

Notch signaling is known to play important roles during retinal development. Recently, Notch signaling has been shown to be active in proliferating Müller glia in acutely damaged chick retina (Hayes et al., 2007). However, the roles of Notch in mature, undamaged retina remain unknown. Thus, the purpose of this study was to determine the role of the Notch-signaling pathway in the postnatal retin...
