title: Gene transfer into mammalian cells using histone-condensed plasmid DNA.
abstract: A recombinant histone (NLS-H1) containing both the SV40 large T antigen nuclear localization signal and the carboxy-terminal domain of human histone H1(0) was produced in bacteria. NLS-H1-plasmid DNA complexes, in the presence of chloroquine, mediated reporter gene transfer into cultured cells with similar efficiencies as plasmid DNA-cationic lipid (lipofectin) complexes. NIH-3T3 or COS-7 cells transfected with NLS-H1-plasmid DNA-lipofectin complexes expressed at least 20 times more luciferase or had at least 2.5 times more beta-galactosidase-positive cells than those transfected with plasmid DNA-lipofectin complexes. Foreign gene expression was also improved by other DNA-binding proteins and cationic lipid formulations, yet the greatest enhancement was obtained with complexes containing either NLS-H1 or calf thymus histone H1. Histone H1-plasmid DNA-lipofectin complexes were internalized by a greater number of cells than plasmid DNA-lipofectin complexes.
