Spuren von Feuchtigkeit / Nässe; Leichte Rillen / Abschürfungen / Risse / Knicke. The epidermal growth factor (EGF) receptor and its downstream signaling networks are crucial in tumor development and maintenance, driving the search for targeted anti-EGF receptor therapies. Extensive research has detailed the EGF receptor's structure, ligand binding domains, intrinsic tyrosine kinase function, and interactions with signaling adaptor proteins like SH2, PTB, and SH3, which are essential for signal transduction. The EGF receptor serves as a central hub for various signaling pathways and interacts with three other family receptors, forming dimers and oligomers in response to at least eleven ligands, some of which have overlapping or distinct functions. This interaction activates multiple second messenger proteins and facilitates cross-talk between systems, adding complexity to the signaling landscape. However, the cross-regulation of the EGF receptor with other anti-apoptotic, mitogenic, and metabolic signaling systems remains less understood. New findings continue to emerge from studying these interactions, although a significant challenge has been the tendency to define signaling pathways without considering their tissue-specific or cell-interaction contexts.

Riassunto

The epidermal gro wth factor (EGF ) receptor and its downstream signal transduction networks have been implicated in the ontology and maintenance of tumor tissues, which has motivated the discovery and development of molecularly targeted anti-EGF receptor therapies. Over decades of study, the EGF receptor structure, its ligand binding domains, the physical biochemistry underlying its intrinsic tyrosine kinase catalytic function and the modular interactions with SH2, PTB, and SH3 domain containing signaling adaptor p- teins required for signal transduction, have been extensively dissected. Not only is the EGF receptor the nexus of many streams of information, but it also forms one part of a calcul- ing device by forming dimers and oligomers with the other three receptors in its family in response to at least eleven ligands (some of which are expressed in multiple forms with overlapping or quite distinct functions). This phenomenon, while recruiting to the inner surface of the cell membrane and activating multiple second messenger proteins, also allows the possibility of cross talk between these systems, permitting a further layer of information to be exchanged. Less well described are the cross re gulation of the EGF receptor and other anti-apoptotic, mitogenic and metabolic signaling systems. The study of these systems has yielded new surprises. One hurdle in these efforts has been that signal transduction pathways have frequently been defined in the generic absence of their tissue-specific or cell-interaction specific context.

Dalla quarta di copertina

The epidermal growth factor (EGF) receptor and its downstream signal transduction networks have been implicated in the ontology and maintenance of tumor tissues, which has motivated the discovery and development of molecularly targeted anti-EGFR therapies. Edited by John Haley and William J. Gullick, EGFR Signaling Networks in Cancer Therapy, is separated into two sections. The first of which probes the molecular pathways and the intersection of signaling networks which are frequently deregulated in human cancers, with a view to describing EGF receptor in a tumor tissue specific context. Meanwhile, the second section illustrates the many ways in which EGF receptor contribute to abnormal survival and migration signaling in cancer cells and to epithelial to mesenchymal transition and metastasis. The book also describes the mitogenic, survival, adhesive and migratory pathways within a framework of interacting subsystems that contribute to the activity and physiological regulation of the receptor in normal and neoplastic tissues. Even though there is still much to learn, this volume explores this fascinating system with compelling information.
