Table 2.

IDUA transgene expression in tissues of MPS I mice treated with different doses and volumes of lentiviral vector. High dose: 1 × 107 TU/g; low dose: 5 × 106 TU/g. ND: non-detectable (< 0.002 nmol/h/mg). Normal heterozygous mice had IDUA levels: 2.7 ± 0.26 nmol/h/mg protein in the brain, 3.8 ± 0.06 in the heart, 1.8 ± 0.1 in the liver and 10.2 ± 0.23 in the spleen. Data are mean ± standard errors. The difference between treated mice and untreated MPS I mice was significant, with a p value of < 0.05.
