Cis- and Trans-Regulatory Mechanisms of Gene Expression in the ASJ Sensory Neuron of Caenorhabditis elegans
... ABSTRACT The identity of a given cell type is determined by the expression of a set of genes sharing common cis-regulatory motifs and being regulated by shared transcription factors. Here, we identify cis and trans ...

Target derived BMP signaling limits sensory neuron number and the extent of peripheral innervation in vivo
... At E15 there was no increase in the density of innervation of the skin in the K14-noggin transgenic animals (Fig. 2). Because this corresponds to the normal period of maximal neuronal death in the trigeminal ganglion, ...
