The Notch signaling pathway controls diverse cell-fate specification events throughout development. The versatility of this pathway to influence different aspects of development comes from its multiple levels of regulation. Upon ligand-induced Notch activation, the Notch intracellular domain (Notch-ICD) is released from the membrane and translocates to the nucleus, where it transduces Notch sig...

Notch is a phylogenetically conserved transmembrane receptor that is required for many aspects of animal development. Upon ligand stimulation, a fragment of Notch is released proteolytically and enters the nucleus to form a complex with the DNA-binding protein CSL (CBF1/Suppressor of Hairless/Lag1) and activate transcription of Notch-CSL target genes. The physical structure of the Notch-CSL com...

The Notch signaling pathway is important for cell-cell communication; it is involved in gene regulation mechanisms that control multiple cell differentiation processes during embryonic and adult life. Notch is present in all metazoans, and vertebrates possess four different Notch receptors: Notch-1, Notch-2, Notch-3, and Notch-4. The aim of the present study was to identify the role of Notch pr...

What would contemporary music scholarship look like if it was no longer imprinted with the disciplinary assumptions, boundaries and divisions inherited from the last century? This article proposes that a generative model for future music studies would take the form of a relational musicology. The model is drawn from the author’s work; but signs of an incipient relational musicology are found sc...

The roles of the Notch pathway proteins in normal adult vascular physiology and the pathogenesis of brain arteriovenous malformations are not well-understood. Notch 1 and 4 have been detected in human and mutant mice vascular malformations respectively. Although mutations in the human Notch 3 gene caused a genetic form of vascular stroke and dementia, its role in arteriovenous malformations dev...

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...

Although aberrant Notch activation contributes to leukemogenesis in T cells, its role in acute myelogenous leukemia (AML) remains unclear. Here, we report that human AML samples have robust expression of Notch receptors; however, Notch receptor activation and expression of downstream Notch targets are remarkably low, suggesting that Notch is present but not constitutively activated in human AML...

Differential precession due to the planet's quadrupole moment tends to destroy the alignment of particles in inclined rings. We propose that alignment is maintained by the self-gravity of the ring. This hypothesis predicts that 8i/8a>0 across the ring. If 8i/i0 <(1, 8e/e0 <(1, a8i/8a<(1, and a8e/8a< 1, a further prediction is that 8i/i0 = 8e/e0 • The a and /3 rings of Uranus may be used to test...

[Purpose] The purpose of this study was to identify the effects of changes in support and inclined boards on lower-extremity muscle activity. [Subjects and Methods] The study subjects were 15 healthy adult males. Aero-Step equipment was used as an unstable support, and an inclined board was used to maintain angles of 0° and 20°. Electromyography was employed to analyze lower-extremity muscle ac...
