Inactivation of the hh regulator ptch is responsible for the gorlin cancer predisposition syndrome. The spectrum of tumors found in gorlin syndrome includes basal cell carcinoma, medulloblastoma, and rarely, rhabdomyosarcoma (rms). A previous report utilizing in situ hybridization has provided initial evidence for the expression of hh targets gli1 and ptch in rms tumors. Procedure to investigate the role of hh pathway signaling in pediatric rms and undifferentiated sarcoma (us) tumors, the expression of hh pathway targets gli1 and ptch was measured. Rna was extracted from archival human tumor specimens collected from pediatric patients enrolled on intergroup rhabdomyosarcoma study iii and iv, and subjected to quantitative reverse transcriptase‐polymerase chain reaction. buy viagra viagra online without a prescription viagra for sale cheap viagra viagra online buy viagra cheap viagra for sale uk canadian pharmacy viagra no prescription viagra online Results expression of gli1 with or without ptch was detected in substantial subsets of embryonal rms (erms) and us tumors but only rarely in alveolar rms tumors. Neither ptch mutations nor activating smo mutations were detected in erms tumors with high gli1 expression. Microarray analysis demonstrated relative overexpression of downstream hh targets in erms tumors with high or intermediate gli1 expression. Unlike a recent report, hh pathway activity in erms tumors did not correlate with a unique clinical phenotype. Conclusions our findings support a role for hh pathway activation in the genesis of a subset of erms and us tumors. Hh signaling may represent a novel therapeutic target in affected tumors.
