Experimental study demonstrates efficient DNA transfection by HIV-1 Vpr C-terminal domain across mammalian cells, indicating an alternative nuclear delivery pathway.

Key Points

To determine whether the DNA-condensing and nuclear import properties of HIV-1 Viral protein R, specifically its C-terminal domain Vpr(52-96), can be utilized for efficient DNA transfection.
Assessed plasmid DNA condensation induced by HIV-1 Viral protein R (Vpr).
Evaluated transfection activity of the C-terminal peptide Vpr(52-96) across multiple human and nonhuman cell lines in comparison to polylysine and established transfection agents.
Investigated the pH dependency of nuclear uptake for Vpr(52-96)-DNA complexes.
Vpr(52-96) mediated DNA transfection across a variety of human and nonhuman cell lines, exhibiting 10- to 1,000-fold higher activity than the standard polycationic reagent polylysine.
Transfection efficiency achieved with Vpr(52-96) was on par with the best-known transfection agents.
Vpr(52-96)-DNA complexes successfully entered the cell nucleus through a pH-independent transport mechanism.
