Transcriptome analyses of organ transplants have until now usually focused on whole tissue samples containing activation profiles from different cell populations. Here, we enriched endothelial cells from rat cardiac allografts and isografts, establishing their activation profile at baseline and on day 2, 3 and 4 after transplantation. Modulated transcripts were assigned to three categories based on their regulation profile in allografts and isografts. Categories A and B contained the majority of transcripts and showed similar regulation in both graft types, appearing to represent responses to surgical trauma. By contrast, category C contained transcripts that were partly allograft-specific and to a large extent associated with interferon-gamma-responsiveness. Several transcripts were verified by immunohistochemical analysis of graft lesions, among them the matricellular protein periostin which was one of the most highly upregulated transcripts but has not been associated with transplantation previously. In conclusion, the majority of the differentially expressed genes in graft endothelial cells are affected by the transplantation procedure whereas relatively few are associated with allograft rejection.

View SamplesPrevious studies in our laboratory have shown that low folate diet (control diet with 2mg folate/kg, low folate diet with 0.3mg folate/kg) can induce intestinal tumors in BALB/c mice. In addition, we reported that C57Bl/6J mice did not form tumors under the same conditions.
Differential gene expression and methylation in the retinoid/PPARA pathway and of tumor suppressors may modify intestinal tumorigenesis induced by low folate in mice.

View SamplesWe used the myoma model in conjunction with gene expression profiling with microarray data as an efficient tool for high throughput analysis and to screen for differentially expressed genes. Our aim was to identify candidates playing an important role in SLPI and/or MMP-promoted tumor invasion by comparing oral carcinoma Ca9-22 cells, which highly express secretory leukocyte protease inhibitor (SLPI) gene, with SLPI-deficient Ca9-22 cells.

View SamplesTo investigate the roles of TAZ in lung fibroblasts, we compared the expression profiles of a lung fibroblast cell line, HFL-1, transfected with control siRNA and siTAZ. Overall design: We collected RNA from HFL-1 cells transfected with control siRNA and siTAZ. Two kinds of TAZ siRNAs (siTAZ #1 and siTAZ #2) were used. Two biological replicates (rep1 and rep2) were used for each condition.
TAZ contributes to pulmonary fibrosis by activating profibrotic functions of lung fibroblasts.

View SamplesTo identify the possible targets in EMT-acquisition after developing acquired platinum resistance in urothelial carcinoma (UC), we examined the changes in global gene expression before and after development of acquired platinum resistance. Comparing two types of acquired platinum resistant UC cells and their corresponding parent cells, in the end we identified 49 genes (25 up-regulated and 24 down-regulated genes) which were commonly changed in two acquired platinum resistant UC cells.
Acquired platinum resistance involves epithelial to mesenchymal transition through ubiquitin ligase FBXO32 dysregulation.
