Project description:Neuroblastoma (NB) is a common pediatric malignancy tumor with poor outcome. Recent studies show that MDM2 protein inhibitors are promising anti-cancer agents. MI-773 is a novel and specific antagonist of MDM2 and the molecular mechanisms of MI-773 in neuroblastoma are still unclear. In this study, we used microarrays to analyze the global change in gene expression as a result of MI-773 treatment in the human neuroblastoma cell line SH-SY5Y.
Project description:Affymetrix SNP6.0 array data used to reveal predictive biomarkers of tumour sensitivity to MI-773 . MI-773 is a recently developed small-molecule inhibitor of the Mouse Double Minute 2 (MDM2) proto-oncogene. Here we report an integrative pharmacogenomic study to gain further insights into the therapeutic potential of the compound

Project description:Neuregulin-1 (NRG-1) is a paracrine factor critical for cardiac development. We have been examining whether the recombinant NRG-1β isoform known as glial growth factor 2 (GGF2) has therapeutic potential for heart failure. In both small and large animals after experimental myocardial infarction (MI) we have found that GGF2 treatment improves myocardial function and limits progressive myocardial remodeling. To understand potential mechanisms for this effect, we compared gene expression in swine by microarray analysis. We used microarrays to compared th the global gene expression underlying the efficacy of GGF2 treatment for heart injury. Left ventricular tissue remote from the site of infarct was collected from each of 8 animals (3 untreated controls, 3 low dose GGF2-treated and 2 high dose GGF2-treated) and processed for gene expression microarray analysis using Affymetrix porcine genome GeneChips.

Project description:Male C57Bl/6 mice were randomized to undergo 5 days of i) a shiftwork protocol (10-hour light: 10-hour dark cycle) before myocardial infarction (MI) surgery, ii) a normal 12-hour light: 12-hour dark environment before MI surgery, iii) a normal 12-hour light: 12-hour dark environment and used as sham controls, or iv) a shiftwork protocol (10-hour light: 10-hour dark cycle) and used as sham controls. MI surgery was performed on the 5th day, after which all mice were returned to a normal 12-hour light: 12-hour dark cycle. Hearts were collected 24-hours post-MI at ZT06. The microarray approach allows the investigation of transcriptome-wide gene expression changes in hearts from mice on a shiftwork cycle or on a regular light:dark cycle before MI.
