Infection with retroviruses containing oncogenes, e.g., Abelson Virus (v-Abl [2]), J3V1 virus (v-Raf plus v-Myc [3]), RIM virus (v-Ha-Ras plus c-Myc [4]), ABLMYC Virus (v-Abl plus c-Myc [5]), accelerates PCT formation, producing ABPC, J3PCs, RIMPCs and ABLMYCPCs, respectively, in as little as 12 days (see Figure 1A and Table 1). The gene discussed is MYC; the disease is infection.
