We monitored Hh:GFP after pulsed expression, and analyzed the movement and colocalization of Hh, Patched (Ptc) and Smoothened (Smo) proteins tagged with GFP or mCherry and expressed at physiological levels from bacterial artificial chromosome transgenes. Hh:GFP...

We also investigate what orients the muscles; these are mostly precisely arranged in the anteroposterior axis. In embryos, a signal from sr -expressing cells attracts the myotubes...

... of a patched homolog, At-ptc , that encodes a putative negative regulator of Hedgehog (Hh) signaling, prevented initiation of the symmetry-breaking cell migration. Knockdown of a smoothened homolog, At-smo , showed that Hh signaling inactivation also arrested the cells at the germ disc center, whereas moderate...

When Hh is absent, its receptor Patched (Ptc...

... interaction between these two signaling pathways, we have inactivated theβ-catenin gene and upregulated Ihh signaling simultaneously in the same cells during endochondral skeletal development using β-catenin and patched 1 floxed alleles. We uncovered previously unexpected roles of Ihh signaling in synovial...

...) in the developing cerebellum, but little is known about the early stages of the disease. Here, we identify a pre-neoplastic stage of medulloblastoma in patched heterozygous mice, a model of the human disease. We show that pre-neoplastic cells are present in the majority of patched mutants,although only 16...

... of lens precursors express genes characteristic of pituitary cells. However, overexpression of shh does not increase median pituitary placode size nor does it upregulate patched ( ptc ) expression in pituitary precursors during early somitogenesis. Our study suggests that by the end of gastrulation, pitx3...

... plays a key role in hedgehog signaling in the early mouse embryo. Here we have used a hypomorphic allele in Disp1(Disp1 Δ 2 ) , to extend our knowledge of Disp1 function in Hh-mediated patterning of the mammalian embryo. Through genetic combinations with null alleles of patched 1 ( Ptch1 ),sonic...

Hh promotes the entry of Sxl into the nucleus in the wing disc. In the anterior compartment, the Hh receptor Patched(Ptc) is required for this effect, revealing Ptc...

Our results indicated that loss of Hhip results in increased hedgehog signaling within the pancreas anlage. Pancreas...

Induction of patched expression, which results from activation by Hh, demonstrates that cells in the anterior half of the tracheal pit are activated. In hh -mutant embryos migration...
