Project description: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.

Project description:As intracellular parasites, viruses exploit cellular proteins at every stage of infection. Adenovirus related outbreaks cause severe acute respiratory illnesses and conjunctivitis, with no specific antiviral therapy yet available. Herein, we investigate human adenovirus (HAdV-D37) pIIIa-host protein interactions by affinity purification and mass spectrometry (AP-MS) screens. We demonstrate that viral pIIIa interacts with ubiquitin-specific protease 9x (USP9x) and Ran-binding protein 2 (RANBP2).

Project description:Adenovirus minor coat protein VI contains a membrane-disrupting peptide that is inactive when VI is bound to hexon trimers. Protein VI must be released during entry to ensure endosome escape. Hexon:VI stoichiometry has been uncertain, and only fragments of VI have been identified in the virion structure. Recent findings suggest an unexpected relationship between VI and the major core protein, VII. According to the high-resolution structure of the mature virion, VI and VII may compete for the same binding site in hexon; and noninfectious human adenovirus type 5 particles assembled in the absence of VII (Ad5-VII-) are deficient in proteolytic maturation of protein VI and endosome escape. Here we show that Ad5-VII- particles are trapped in the endosome because they fail to increase VI exposure during entry. This failure was not due to increased particle stability, because capsid disruption happened at lower thermal or mechanical stress in Ad5-VII- compared to wild-type (Ad5-wt) particles. Cryoelectron microscopy difference maps indicated that VII can occupy the same binding pocket as VI in all hexon monomers, strongly arguing for binding competition. In the Ad5-VII- map, density corresponding to the immature amino-terminal region of VI indicates that in the absence of VII the lytic peptide is trapped inside the hexon cavity, and clarifies the hexon:VI stoichiometry conundrum. We propose a model where dynamic competition between proteins VI and VII for hexon binding facilitates the complete maturation of VI, and is responsible for releasing the lytic protein from the hexon cavity during entry and stepwise uncoating.

Project description:Mucopolysaccharidosis (MPS) VII is a lysosomal storage disorder characterized by deficient activity of β-glucuronidase, leading to progressive accumulation of incompletely degraded heparan, dermatan and chondroitin sulfate glycosaminoglycans (GAGs). Patients with MPS VII exhibit progressive skeletal deformity including kyphoscoliosis and joint dysplasia, which decrease quality of life and increase mortality. Previously, using the naturally-occurring canine model, we demonstrated that one of the earliest skeletal abnormalities to manifest in MPS VII is failed initiation of secondary ossification in vertebrae and long bones at the requisite postnatal developmental stage. The objective of this study was to obtain global insights into the molecular mechanisms underlying this failed initiation of secondary ossification using whole transcriptome sequencing (RNA-Seq). Epiphyseal tissue was isolated from the vertebrae of control and MPS VII affected dogs at 9 and 14 days-of-age (n=5 for each group). Differences in global gene expression across this developmental window for both cohorts were established using RNA-Seq. A targeted analysis focused on signaling pathways important in the regulation of endochondral ossification, and a subset of gene expression changes were validated using qPCR. Principal Component Analysis revealed clustering of samples from each group, indicating clear effects of both age and disease state. At 9 days-of-age, 1375 genes were significantly differentially expression between MPS VII and control, and by 14 days-of-age, this increased to 4719 genes. Osteoactivin (GPNMB) was the top upregulated gene in MPS VII at both ages. Targeted analysis revealed temporal changes in gene expression from 9 to 14 days-of-age in control samples consistent with chondrocyte maturation, cartilage resorption, and osteogenesis. In MPS VII samples, however, elements of key osteogenic pathways such as Wnt/β-catenin and BMP signaling were dysregulated. In conclusion, this study represents the first step towards identifying druggable therapeutic targets and putative biomarkers for bone disease in MPS VII patients during postnatal growth.

Project description:We used microarray to detect pathway differences in the various brain regions in a monogenic in mucopolysaccharidosis type VII ( MPS VII ), a mouse model of a lysosomal storage disease A number of changes revealed unexpected system and process alterations, such as upregulation of the immune system with few inflammatory changes (a significant difference from the closely related MPS IIIb model), down-regulation of major oligodendrocyte genes even though white matter changes are not a feature histopathologically, and a plethora of developmental gene changes. 94 samples, no replicates, made up of half normals and half MPS mutant mice for the MPS VII mutation backcrossed on a C3h-heouj background
