PAX3 and neoplasm: The expression levels of Caveolin family members were analysed by western blot using four human RMS cell lines (embryonal RD, RD12, RD18 and alveolar RH30) and two mouse primary tumor cultures established from transgenic Myf6Cre/p53−/− and Myf6Cre/Pax3-Foxo1/p53−/− mice (embryonal U57810 and alveolar U23674, respectively) [21], [24].
