... ossification Receptor tyrosine kinase Neural crest Mesoderm Bone formation is a complex process in which mesenchymal cells become osteoblasts and deposit bone matrix. There are generally two pathways to form bone. The mesenchymal cells may first form a cartilaginous template that is later replaced...

...Smita Amarnath; Leslie M. Stevens; David S. Stein Formation of the Drosophila embryonic termini is controlled by the localized activation of the receptor tyrosine kinase Torso. Both Torso and Torso's presumed ligand, Trunk, are expressed uniformly in the early embryo. Polar activation of Torso...

... to those seen with other signaling mutants, such as in the JNK pathway, and we demonstrate that JNK signaling is not perturbed by altering Pvr receptor tyrosine kinase activity. Rather, modulation of Pvr levels in the ectoderm has an impact on PIP3 membrane accumulation, consistent with a link to PI3K...

These results provide new insight into the signaling molecules downstream of FGF receptor tyrosine kinases in cardiac progenitors. The FGF family of regulatory polypeptides...

... known as linotte ) receptor tyrosine kinase as an essential component of adult MB development. Here we show, using MARCM clones, a non-cell-autonomous requirement for the DRL receptor in MB development. This result is in accordance with the pattern of DRL expression, which occurs throughout development...

... activities by activating diverse isotypes of FGF receptor tyrosine kinases (FGFRs). Among the FGFs, FGF7 and FGF10 have been implicated in the regulation of prostate development and prostate tissue homeostasis by signaling through the FGFR2 isoform. Using conditional gene ablation with the Cre-LoxP system...

We demonstrate that the molecular mechanism underlying downregulation of YAN involves CRM1-mediated nuclear export and define a novel role in this context for MAE, a co-factor previously implicated...

...Ruth Herbst; Ekaterina Avetisova; Steven J. Burden Mice lacking Musk, a muscle-specific receptor tyrosine kinase that is activated by agrin, fail to form neuromuscular synapses and consequently die at birth because of their failure to move or breathe. We produced mice that express a chimeric...
