Virus-Free Adenocarcinoma of the Frog (Summer Phase Tumor) Transcribes Lucké Tumor Herpesvirus-Specific RNA

[ 3 H]RNA isolated from "virus-free," summer phase, renal adenocarcinomas of Rana pipiens labeled with [ 3 H]uridine hybridizes with DNA of herpesvirus particles isolated from the winter phase Lucke tumor. Transcription of the herpesvirus genome in virus-free tumors provides additional evidence for the viral etiology of this tumor.
