PAN RNA: transcriptional exhaust from a viral engine

Kaposi's sarcoma-associated herpesvirus (KSHV), also designated human herpesvirus 8 (HHV-8), has been linked to Kaposi's sarcoma, as well as to primary effusion lymphoma (PEL), and a subset of multicentric Castleman's disease. KSHV genomes are maintained as episomes within infected cells and the virus exhibits a biphasic life cycle consisting of a life-long latent phase during which only a few viral genes are expressed and no viral progeny are...
