Genetics of mouse mammary tumor virus-induced mammary tumors: linkage of tumor induction to the gag gene.

abstract：:Kaposi's sarcoma-associated herpesvirus (KSHV) encodes a cluster of 12 microRNAs (miRNAs) that are processed from a transcript that is embedded within the major latency control region. We have generated a deletion mutation that eliminates 10 of the 12 viral miRNAs from the KSHV bacmid by using recombineering methods. ...
