| Research Abstract |
1. Promoter activities of various murine retroviruses were compared in human hematopoietic stem cells and hepatocytes.
2. The U3 region of the spleen-focus forming virus (SFFVp) provided the stronger activity than that of Moloney murine leukemia virus (MoMLV) in human stem cells. The leader sequence from MoMLV supressed the expression but the sequence from murine embryonic stem cell virus (MESV) did not. FMEV-type vectors were developed in combination of the SFFVp U3 and the leader from MESV. These vectors provided superior transgene expression in human stem cells than Moloney-based vectors.
3. The U3 region of SFFVp provided the stronger activity than that of MoMLV in human hepatocellular carcinoma cell lines in vitro. The leader sequence from MoMLV supressed the expression but the sequence from MESV did not. FMEV-type vectors provided superior transgene expression in human hepatocellular carcinoma cell lines and also in murine hepatocytes in vivo.
