Project description:In the current work we have compared the transcriptomic and eQTL profiles of the porcine skeletal muscle and liver by using a data set of 103 Duroc pigs genotyped with the Illumina SNP60 BeadChip and with available microarray measurements of gene expression for both tissues.
Project description:This experiment was performed to improve gene expression analysis of non-human primates using human microarrays. To improve the interpretation of cross-species hybridizations a probe match table was created. We validated this table by comparing gene expression data obtained from human and M. fascicularis. Two tissues were used in this comparison: Liver and muscle.
Project description:With the extensive use of microarray technology as a potential prognostic and diagnostic tool, the comparison and reproducibility of results obtained from the use of different platforms is of interest. The integration of those datasets can yield more informative results corresponding to numerous datasets and microarray platforms. We developed a novel integration technique for microarray gene-expression data derived by different studies for the purpose of a two-way Bayesian partition modelling which estimates co-expression profiles under subsets of genes and between biological samples or experimental conditions. The suggested methodology transforms disparate gene-expression data on a common probability scale to obtain inter-study-validated gene signatures. We evaluated the performance of our model using artificial data. Finally, we applied our model to six publicly available cancer gene-expression datasets and compared our results with well-known integrative microarray data methods. Our study shows that the suggested framework can relieve the limited sample size problem while reporting high accuracies by integrating multi-experiment data.
Project description:In order to identify the deregulated genes in hepatocellular carcinama, we applied the Agilent two-color chip cDNA microarray to explore the expression of genes in hepatocellular carcinoma and nontumor liver tissue samples. Hepatocellular carcinoma tissues and nontumor liver tissues were obtained from hepatocellular carcinoma patients during surgery. In these samples, RNA was extracted and cDNA microarray was performed to identify the differentially expressed genes in these samples.
Project description:We generated a tamoxifen-inducible skeletal muscle-specific Bmal1 knockout mouse model and performed a time-course microarray experiment to identify gene expression changes downstream of the molecular clock. We report the transcrpt expression profiles in adult gastrocnemius skeletal muscle harvested from iMS-Bmal1-/- and at 4 hour intervals for a full circadian time-course (6 time-points).
