... induction. Secondary senescence was initially shown as a paracrine response to the secretion of cytokines from primary senescent cells. More recently, juxtacrine Notch signalling has been implicated in mediating secondary senescence induction. Primary and secondary senescent induction results in distinct...

...Thaned Kangsamaksin; Ian W. Tattersall; Jan Kitajewski The Notch signalling pathway is a key regulator of developmental and tumour angiogenesis. Inhibition of Delta-like 4 (Dll4)-mediated Notch signalling results in hyper-sprouting, demonstrating that Notch regulates tip-stalk cell identity...

... development and postnatal life. The interplay between the VEGF and Notch signalling pathway has been recently found to regulate the morphogenic events leading to the growth of new vessels by sprouting. Angiogenesis can also take place by an alternative process, i.e. intussusception or vascular splitting...

...Chern Ein Oon; Adrian L. Harris Notch signalling is a key pathway controlling angiogenesis in normal tissues and tumours. This has become a major focus of development of anticancer therapy, but to develop this appropriately, we need further understanding of the mechanisms of regulation of Dll4...

.... Protein–protein interfaces are widely recognized to be challenging targets as they tend to be large and relatively flat, and therefore usually do not have the concave binding sites that characterize the so-called ‘druggable genome’. One such prototypic multiprotein target is the Notch transcription...

...Lars Jakobsson; Katie Bentley; Holger Gerhardt ECs (endothelial cells) in the developing vasculature are heterogeneous in morphology, function and gene expression. Inter-endothelial signalling via Dll4 (Delta-like 4) and Notch has recently emerged as a key regulator of endothelial heterogeneity...

... targeting them for degradation in lysosomes. In the present paper, we review how ESCRT-mediated receptor down-regulation affects signalling downstream of Notch and growth factor receptors, and how ESCRTs may control cell proliferation, survival and cytoskeletal functions and contribute to tumour suppression...

... in Drosophila oocytes. Recent data showed that this regulatory process is required for somitic segmentation in Xenopus . Inactivation of EDEN-BP (EDEN-binding protein) causes severe segmentation defects, and the expression of segmentation markers in the Notch signalling pathway is disrupted. We showed...
