BACKGROUND Receptors of the Notch family affect the determination of many cell types. In the Drosophila eye, Notch antagonises the basic helix-loop-helix (bHLH) protein atonal, which is required for R8 photoreceptor determination. Similar antagonism between Notch and proneural bHLH proteins regulates most neural cell determination, however, it is uncertain whether the mechanisms are similar in ...

To meet the requirement of radio frequency signal processing tasks among various bands, here we have demonstrated a reconfigurable microwave photonic bandpass filter by flipping optical notch spectrum cascaded microring resonator (MRR) pool chip through phase modulation. We experimentally characterize MRR on Si3N4 platform and evaluate system performance established (MPF). In system, center can...

During mammalian central nervous system (CNS) development, an enormous variety of cell types are generated. This cell diversity is due in part to asymmetrical cell division. Asymmetrical segregation of Numb, a cell-determinant protein, can result in the differential activation of the Notch pathway. The Notch pathway defines one of the few fundamental signalling pathways that govern metazoan dev...

This paper presents a high performance notch filtering for real time suppression of power line interference in a general signal. The disturbing signal is suppressed using an optimal notch FIR filter with tunable notch frequency. The tuning of the filter preserves its selectivity, most importantly the specified attenuation at the notch frequency. One example and two Matlab functions demonstrate ...

Members of the Notch family of transmembrane receptors play an important role in cell fate determination. Over the past decade, a role for Notch in the pathogenesis of hematologic and solid malignancies has become apparent. Numerous cellular functions and microenvironmental cues associated with tumorigenesis are modulated by Notch signaling, including proliferation, apoptosis, adhesion, epithel...

The Notch signaling pathway plays a significant role in embryonic cell fate determination and adult tissue homeostasis. Various studies have demonstrated the deep involvement of Notch signaling in the development of the pancreas and the lateral inhibition of Notch signaling in pancreatic progenitor differentiation and maintenance. The targeted inactivation of the Notch pathway components promot...

The Notch signalling pathway is involved in many processes where cell fate is decided. Previous work showed that Notch is required at successive steps during R8 specification in the Drosophila eye. Initially, Notch enhances atonal expression and promotes atonal function. After atonal autoregulation has been established, Notch signalling represses atonal expression during lateral specification. ...

Notch signaling is a major pathway in cell fate decisions. Since the first reports showing the major role of Notch in embryonic development, a considerable and still growing literature further highlights its key contributions in various pathological processes during adult life. In particular, Notch is now considered as a major player in vascular homeostasis through the control of key cellular f...

Notch signaling has pleiotropic context-specific functions that have essential roles in many processes, including embryonic development and maintenance and homeostasis of adult tissues. Aberrant Notch signaling (both hyper- and hypoactive) is implicated in a number of human developmental disorders and many cancers. Notch receptor signaling is mediated by tightly regulated proteolytic cleavages ...

Notch signaling is an extremely conserved and widely used mechanism regulating cell fate in metazoans. Interaction of Notch receptors (Notch) with their ligands (Delta-like or Jagged) leads to cleavage of the Notch intracellular domain (NICD) that migrates into the nucleus. In the nucleus, NICD associates with a transcription factor, RBP-Jk. The NICD-RBP-Jk complex, in turn, upregulates express...
