Research on gene therapy described by scientists at Mount Sinai School of Medicine

Researchers detail in "Metabolic basis of sexual dimorphism in PKU mice after genome-targeted PAH gene therapy," new data in gene. "We have previously reported a transgene delivery system based on phiBT1 bacteriophage integrase that results in targeted insertion of transgenes into mammalian genomes, and its use in the delivery of murine phenylalanine hydroxylase (PAH) complementary DNA (cDNA) into the hepatocytes of male phenylketonuria (PKU) mice, leading to a complete and permanent correction of their hyperphenylalaninemic phenotype. In this study, we report only partial phenotypic correction in female PKU mice, even though hepatic PAH activities in both sexes after gene treatment were...
