We have shown elsewhere that both the major immediate-early gene ( MIE ) and lytic cycle infectious progeny virus expression can be induced in otherwise nonpermissive monocyte-like U-937 cell cultures infected with either human CMV ( HCMV ) or simian CMV ( SCMV ) by treatment with the phorbol ester 12-O-tetradecanoylphorbol-13-acetate ( TPA ).
