A lentiviral vector with novel multiple cloning sites: Stable transgene expression in vitro and in vivo
چکیده انگلیسی

Gene delivery has become an important tool for biological research and gene therapy trials. Lentiviral vector (LV) mediated gene transfer is a preferred approach for stable, sustained transgenic expression. We report here step-wise development of an Indian human immunodeficiency virus type 2 (HIV-2) isolate derived third generation lentiviral vector with a novel, versatile multiple cloning site (MCS) that can also facilitate single step sub-cloning of a PCR amplified transgene cassette by T/A cloning strategy apart from useful cohesive/blunt end cloning. Efficiency of the vector systems was functionally demonstrated by development of a transgenic enhanced green fluorescence protein (GFP) expressing cell line. Further, a GFP down regulated cell line was derived from the said cell line through LV mediated shRNA expression by cloning the GFP-shRNA cassette using the T/A cloning strategy. Subsequently long term expression of GFP transgene in nude mouse spleen/liver was also documented till 30 days. This LV platform with the enhanced user friendly cloning options will be an important advancement in gene transfer technology.
