Description of Research
In collaboration with others, a series of metabolic diseases caused by deficient enzyme activities are being studied, including mucopolysaccharidoses (MPS) I, VI, and VII (alpha-L-iduronidase, 4-sulfatase, and ß-glucuronidase deficiencies, respectively), alpha mannosidosis (alpha-mannosidase deficiency), I-cell disease (N-acetylglucosamine-1-phosphotransferase), Krabbe disease (galactosylceramidase), and acute intermittent porphyria (PBG-deaminase deficiency). Five of these diseases are lysosomal storage disorders with clinical phenotypes in the animals that are the same as in affected children. Experiments include administering recombinant human alpha-L-iduronidase intravenously to cats with MPS I and gene therapy using retroviral and AAV vectors. The gene therapy experiments are being performed in MPS I cats and dogs, MPS VI cats, and MPS VII dogs using the species-specific cDNAs except feline MPS I. The somatic cell gene therapy experiments include a) intraocular injections of AAV-4-sulfatase vector virus in MPS VI cats, b) neonatal intravenous retrovirus gene therapy in MPS I and VI cats, MPS I dogs, and MPS VII dogs, and c) intramuscular AAV vectors containing the feline 4S cDNA and human SUMF-1 cDNA.
