Severe cutaneous injuries continue to result from exposure to sulfur mustard [bis(2-chloroethyl)sulfide; HD] and thermal burns. Microarray analysis was utilized in this study to evaluate transcriptional changes in porcine skin assessing the underlying repair mechanisms of HD and thermal injury involved in wound healing. Four ventral abdominal sites on each of 4 weanling swine were exposed to 400 microL undiluted HD or a heated brass rod (70 degrees C) for 8 minutes and 45-60 seconds, respectively. At 7 days postexposure, skin samples were excised and total RNA was isolated, labeled, and hybridized to Affymetrix GeneChip (Santa Clara, CA, USA) Porcine Genome Arrays (containing 20,201 genes). Based on the gene expression patterns in HD- and thermal-exposed skin at 7 days, the transcriptional profiles do not differ greatly. HD and thermal exposures promoted similar changes in transcription, where 270 and 283 transcripts were increased with HD and thermal exposures, respectively. Both exposures promoted decreases in 317 and 414 transcripts, respectively. Of the significantly increased transcripts, at least 77% were commonly expressed in both HD- and thermal-exposed skin, whereas at least 67% of decreased transcripts were common between both exposure types. Six of the top 10 biological functions were common to HD and thermal injury in which 9 canonical pathways were shared. The present study illustrates the similarities found between HD and thermal injury with respect to transcriptional response and wound healing and identifies specific genes (CXCL2, CXCR4, FGFR2, HMOX1, IGF1, PF4, PLAU, PLAUR, S100A8, SPP1, and TNC) that may be useful as potential therapeutic targets to promote improved wound healing.

Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of Johne's disease, which causes considerable economic loss in the dairy industry and has a possible relationship to Crohn's disease (CD) in humans. As MAP has been detected in retail pasteurized milk samples, its transmission via milk is of concern. Despite its possible role in the etiology of CD, there have been few studies examining the interactions between MAP and human cells. In the current study, we applied Ingenuity Pathway Analysis to the transcription profiles generated from a murine model with MAP infection as part of a previously conducted study. Twenty-one genes were selected as potential host immune responses, compared with the transcriptional profiles in naturally MAP-infected cattle, and validated in MAP-infected human monocyte-derived macrophage THP-1 cells. Of these, the potential host responses included up-regulation of genes related to immune response (CD14, S100A8, S100A9, LTF, HP and CHCIL3), up-regulation of Th1-polarizing factor (CCL4, CCL5, CXCL9 and CXCL10), down-regulation of genes related to metabolism (ELANE, IGF1, TCF7L2 and MPO) and no significant response of other genes (GADD45a, GPNMB, HMOX1, IFNG and NQO1) in THP-1 cells infected with MAP.

Myocardial ischemia/reperfusion (MI/R) injury is a complex phenomenon that causes severe damage to the myocardium. However, the potential molecular mechanisms of MI/R injury have not been fully clarified. We identified potential molecular mechanisms and therapeutic targets in MI/R injury through analysis of Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were found between MI/R injury and normal samples, and overlapping DEGs were found between GSE61592 and GSE67308. Gene Ontology (GO) and pathway analysis were performed for overlapping DEGs by Database for Annotation, Visualization and Integration Discovery (DAVID). Then, a network of protein-protein interaction (PPI) was constructed through the Search Tool for the Retrieval of Interacting Genes (STRING) database. Potential microRNAs (miRNAs) and therapeutic small molecules were screened out using microRNA.org database and the Comparative Toxicogenomics database (CTD), respectively. Finally, we identified 21 overlapping DEGs related to MI/R injury. These DEGs were significantly enriched in IL-17 signaling pathway, cytosolic DNA-sensing pathway, chemokine signaling, and cytokine-cytokine receptor interaction pathway. According to the degree in the PPI network, CCL2, LCN2, HP, CCL7, HMOX1, CCL4, and S100A8 were found to be hub genes. Furthermore, we identified potential miRNAs (miR-24-3p, miR-26b-5p, miR-2861, miR-217, miR-4251, and miR-124-3p) and therapeutic small molecules like ozone, troglitazone, rosiglitazone, and n-3 polyunsaturated fatty acids for MI/R injury. These results identified hub genes and potential small molecule drugs, which could contribute to the understanding of molecular mechanisms and treatment for MI/R injury.
