... site. The multiple peptides on the functionalized liposome are arranged with the same average spacing as the binding sites of the PA molecule, which permits a firmer bond between the two, explains Dr. Kane. When the inhibitor is bound tightly to PA, the subsequent steps of enzyme entry cannot occur and the t...

Intravenous gene therapy protects normal tissue of mice during whole-body radiation

... effects of manganese superoxide dismutase plasmid liposome (MnSOD-PL) gene therapy on the bone marrow during whole-body irradiation. The researchers found that in a control group of mice that received an initial 9 Gy dose of radiation there was 80 percent survival at 30 days compared to 93.3 percent survival...
