The selleck chem Perifosine integrity of total RNA also passed analysis with the Bioanalyzer 2100 and RNA 6000 Nano LabChip Kit with RIN number 6. Microarray analyses Agilent Oligo microarrays were used to determine global gene expression of 36 samples. Individual microarrays were performed for each sample. Hybridization, washing, and scanning were done according to standard Agilent protocols. Generated array images were loaded into Feature Extraction Software for feature data extraction, and data analysis was performed with MultiExperiment Viewer. Array data have been uploaded to NCBIs Gene Expression Omnibus. For more informa tion, please refer to Li et al. To obtain high confidence gene expression data, we mapped 43,603 probes to the pig re ference genome allowing up to one mismatch, and fur ther filtered unannotated pig target sequences which resulting 4,309 genes were used in subsequent analysis.

To identify differentially expressed mRNAs for the clustering analysis, we used three way ANOVA for comparisons. Resulting P values of above tests were corrected with adjusted Bonferroni method. Construct modules of coexpressed genes For LDM and PMM separately, modules of highly coexpressed genes were constructed using pair wise average linkage cluster analysis as previously described. We kept repeating this as an iterative process until the most significantly correlated pair was r 0. 8. To visualize the correlations between probes within the modules, we constructed colored heatmaps by plotting pair wise correlation values of expression of all the probes within the modules.

To calculate significance of overlap in gene content between modules and between different datasets, we performed Fishers exact tests. Function enrichment analysis of genes To elucidate the biological mechanisms associated with the genes that are correlated to the phenotypic traits, we performed functional enrichment analysis of Gene Ontology for genes using DAVID software. Quantitative PCR We selected six genes randomly to validation experiment using Q PCR. Primer sequences used for the Q PCR are shown in Additional file 9, Table S6. Porcine ACTB, TBP and TOP2B were simultaneously used as endogenous con trol genes. Relative expression levels of objective mRNAs were calculated using the Ct method. Inflammation is the result of a cascade of physiological and immunological reactions that aim to localize toxic materials, fight pathogens and prevent tissue injury.

The inflammatory response Cilengitide consists of the sequential release of mediators including inflammatory cytokines and the recruitment of circulating leukocytes that become activated at the inflammatory site and release further mediators. In most cases, macrophage activation constitutes the key orchestration and regulation event of the inflammatory response.
