View SamplesWe 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
Dysregulation of gene expression in a lysosomal storage disease varies between brain regions implicating unexpected mechanisms of neuropathology.

View SamplesThe gas-1(fc21) mutation affects the 49 kD subunit of complex I, decreasing the rate of complex I-dependent oxidative phosphorylation. This is a model for human mitochondrial respiratory chain disease. NAD+ and PPAR-modifying drugs may confer benefits with respect to lifespan in these short-lived mutant worms. Analysis of gas-1(fc21) electron transport chain complex I mutants treated either starting in development or in young adulthood only with nicotinic acid (1 mM), resveratrol (50 microM), rosiglitazone (5 mM) or fenofibrate (14 microM) is presented. The goal is to detect transcriptional changes in clusters of genes using gene set enrichment analysis to explain treament effects in these mutant worms.

View SamplesBehavioral transitions Young infant rats paradoxically prefer odors paired with shock but older pups learn aversions. This transition is amygdala- and corticosterone-dependent.
Transitions in infant learning are modulated by dopamine in the amygdala.

View SamplesMetastasis via the lymphatics is a major risk factor in squamous cell carcinoma of the oral cavity (OSCC). We sought to determine whether the presence of metastasis in the regional lymph node could be predicted by a gene expression signature of the primary tumor. A total of 18 OSCCs were characterized for gene expression by hybridizing RNA to Affymetrix U133A gene chips. Genes with differential expression were identified using a permutation technique and verified by quantitative RT-PCR and immunohistochemistry. A predictive rule was built using a support vector machine, and the accuracy of the rule was evaluated using crossvalidation on the original data set and prediction of an independent set of four patients. Metastatic primary tumors could be differentiated from nonmetastatic primary tumors by a signature gene set of 116 genes. This signature gene set correctly predicted the four independent patients as well as associating five lymph node metastases from the original patient set with the metastatic primary tumor group. We concluded that lymph node metastasis could be predicted by gene expression profiles of primary oral cavity squamous cell carcinomas. The presence of a gene expression signature for lymph node metastasis indicates that clinical testing to assess risk for lymph node metastasis should be possible.

View SamplesWe show that infant trauma, as modeled by infant paired odor-shock conditioning, results in later life depressive-like behavior that can be modulated by learned infant cues (i.e., odor previously paired with shock). We have previously shown that this infant attachment odor learning paradigm results in the creation of a new artificial maternal odor that is able to control pup behavior and retain its value throughout development. Here, we assess the mechanism by which this artificial maternal odor is able to rescue depressive-like behavior and show that this anti-depressant like effect results in glucocorticoid and serotonin (5-HT) related changes in amygdala gene expression and is dependent on amygdala 5-HT. Furthermore, increasing amygdala 5-HT and blocking corticosterone (CORT) in the absence of odor mimics the adult rescue effects elicited by the artificial maternal odor, suggesting a mechanism by which odor presentation exerts its repair effects.

View SamplesWe explored the hypothesis that Serotonin (5HT) receptor signaling, that can be enhanced with 5HT transporter blockade with Fluoxetine (Fluox), in the aortic valve may vary based upon the biomechanical activity of the aortic valve leaflet.
Aortic valve cyclic stretch causes increased remodeling activity and enhanced serotonin receptor responsiveness.
