A loss-of-function ras allele dominantly suppresses the PAX7-FKHR muscular phenotype. (a) Representative hemisegments of wild-type (MHC-Gal4, UAS-GFP) musculature (same animal as shown in Fig.1a). (b) Representative hemisegments of abnormal MHC-Gal4, UAS-PAX7-FKHR musculature. (c) Representative hemisegments of MHC-Gal4, UAS-PAX7-FKHR musculature with one loss-of-function rasE2f allele. The number of intact myofibers is significantly increased in this genetic background. The musculature is highlighted by the UAS-GFP reporter.
