ABSTRACT
<p><b>OBJECTIVE</b>To detect over-expression of AChR-gamma mRNA in rhabdomyosarcoma tissues by duplex RT-PCR and discuss its potential in diagnosis of rhabdomyosarcoma.</p><p><b>METHODS</b>Duplex RT-PCR was applied to the simultaneous detection of AChR-alpha and gamma subunit messenger RNA in 17 cases of rhabdomyosarcoma (9 ERMS, 6 ARMS, 2 PRMS). 20 cases of non-rhabdomyosarcomous small round cell tumors (6 poorly differentiated synovial sarcomas, 6 ES/PNET, 6 lymphomas, 2 neuroblastomas) and three normal muscle samples were also detected for AChR-alpha and gamma mRNA by the same method.</p><p><b>RESULTS</b>AChR-alpha and AChR-gamma mRNA were expressed in all the cases of rhabdomyosarcoma. The rate of quantity in both transcripts was AChR-gamma/AChR-alpha >or= 1, but the rate for three normal muscle samples was < 1. Cases of non-rhabdomyosarcomous small round cell tumors were all negative for AChR-gamma.</p><p><b>CONCLUSION</b>AChR-gamma mRNA expression detected by molecular genetic methods is useful in diagnosis and differential diagnosis of rhabdomyosarcoma.</p>
