title: Translocation of c-sis protooncogene in peripheral neuroepithelioma.
abstract: Molecular genetic analysis of the c-sis protooncogene was performed on two neuroepithelioma cell lines carrying a t(11;22)(q24;q12). The c-sis protooncogene was found by in situ hybridization to be translocated from its germline position on chromosome #22 to the derivative chromosome #11 in each cell line. However, it was not rearranged or amplified in either cell line examined. In addition, we did not detect c-sis transcripts in Northern blots of poly (A)+ RNA. This is similar to results found in Ewing's sarcoma, which carries a cytogenetically indistinguishable translocation from neuroepithelioma.
