Receptor Tyrosine Kinase (RTK)/Ras GTPase/MAP kinase (MAPK) signaling pathways are used repeatedly during metazoan development to control many different biological processes. In the nematode Caenorhabditis elegans, two different RTKs (LET-23/EGFR and EGL-15/FGFR) are known to stimulate LET-60/Ras...

One of the most common intracellular signaling pathways triggered by RTKs is known as the mitogen-activated protein (MAP) kinase cascade, because it involves three serine-threonine kinases. The pathway starts with the activation of Ras, a small G protein anchored to the plasma membrane. In its...
elegans have provided much insight into the basic framework ofthis RTK/Ras/MAPK signaling pathway, its regulation, how it elicits cell-type specific responses, and how itinteracts with other signaling pathways such as the Wnt and Notch pathways.1. IntroductionReceptor Tyrosine Kinase (RTK)/Ras ...
Prostate cancer lineage plasticity is a key driver in the transition to neuroendocrine prostate cancer (NEPC), and the RTK/RAS signaling pathway is a well-established cancer pathway. Nevertheless, the comprehensive link between the RTK/RAS signaling path
Thus, melanomas escape B-RAF(V600E) tar-geting not through secondary B-RAF(V600E) mutations but via receptor tyrosine kinase (RTK)-mediated activation of alternative survival pathway(s) or activated RAS-mediated reactivation of the MAPK pathway, suggesting additional therapeutic strategies.Nature...
