Microarray analysis of Normal and MPS VII mouse aorta


ABSTRACT: Mucopolysaccharidosis VII (MPS VII) is due to mutations within the gene encoding the lysosomal enzyme beta-glucuronidase, and results in the accumulation of glycosaminoglycans. MPS VII causes aortic dilatation and elastin fragmentation. In this study we performed microarray analysis of ascending aortas from normal and MPS VII mice, trying to find out possible genes responsible for the phenotype observed. In addition, during our breeding strategy, we noticed that some MPS VII mice had less dilated aortas, and we proposed that an yet-unidentified gene could be responsible for the difference observed. We therefore included in the analysis two MPS VII mice with aortas that were not dilated. Total RNA extracted from ascending aortas from 3 Normal mice, 3 MPS VII mice with dilated aortas and 2 MPS VII mice with aortas that were not dilated.

Mucopolysaccharidosis VII (MPS VII) is due to mutations within the gene encoding the lysosomal enzyme β-glucuronidase, and results in the accumulation of glycosaminoglycans. MPS VII causes aortic dilatation and elastin fragmentation, which is associated with upregulation of the elastases cathepsin S (CtsS) and matrix metalloproteinase 12 (MMP12). To test the role of these enzymes, MPS VII mice were crossed with mice deficient in CtsS or MMP12, and the effect upon aortic dilatation was determined  ...[more]
