GLI1 and embryonal rhabdomyosarcoma: However, there is an ongoing discussion regarding whether the survival of ERMS patients is linked to Gli1 and Ptch1 expression level—microarray analysis of rhabdomyosarcoma samples showed that the survival rate, age, tumor stage, group, and the primary anatomic site did not correlate with the expression of Gli1 mRNA transcripts (Pressey et al. 2011).
