To characterize the product of this new oncogenic ELE1/RET rearrangement, here designated as RET/PTC4, we performed an immunoprecipitation and Western blot analysis on cell extracts from NIH3T3 transfectants.     ///    "Alternatively, targeted radiation effects could be responsible for the atypical RET rearrangement producing RET/PTC4 oncogene..
