Physiological, anatomical, and clinical laboratory analytic scoring systems (APACHE, Injury Severity Score (ISS)) have been utilized, with limited success, to predict outcome following injury. We hypothesized that a peripheral blood leukocyte gene expression score could predict outcome, including multiple organ failure, following severe blunt trauma.

View SamplesEpstein-Barr virus (EBV)-transformed lymphoblastoid cell lines (LCLs) provide a conveniently accessible and renewable resource for functional studies in humans. The ability to accumulate multidimensional data pertaining to the same individual cell lines, from complete genomic sequences to detailed gene regulatory profiles, further enhances the utility of LCLs as a model system. A lingering concern, however, is that the changes associated with EBV transformation of LCLs reduce the usefulness of LCLs as a surrogate model for primary tissues. To evaluate the validity of this concern, we compared global gene expression profiles between CD20+ primary B cells and CD3+ primary T cells sampled from six individuals. Six independent replicates of transformed LCLs were derived from each sample.

View SamplesTGF is one of most intensively studied regulators of extracellular matrix formation, and has been implicated in the development of pulmonary fibrosis in different models. However, little is know about the role of miRNAs in TGF mediated fibrogenic gene regulation. By using miRNA qRT-PCR array, we have identified miRNAs whose expression are regulated by TGF in IMR-90 cells. Among those down-regulated miRNAs are miR-29 family members. Knockdown miR-29 in IMR-90 cells results in up-regulation of a large number of extracellular matrix and fibrogenic genes including family members of collagen, laminin, integrin, ADAM and MMP, many of them are predicted or confirmed miR-29 targets. Hierarchichal clustering analysis of mRNA array data revealed that many extracellular matrix and fibrogenic genes up-regulated by TGF in IMR-90 cells, are also up-regulated in miR-29 KD cells. Moreover, the similar set of extracellular matrix and fibrogenic genes is also significantly up-regulated in bleomycin treated mouse lungs. Together, our data strongly suggest that downstream of the TGF, miR-29 is a master modulator of genes involved in extracellular matrix formation and might play a significant role in pulmonary fibrosis.

View SamplesIn the present study, we have investigated the effect of CpG Oligodeoxynucleotides (CpG-ODN) on the outcome of Plasmodium infection of the mosquito vectors Anopheles stephensi and Anopheles gambiae and on the modulation of mosquito immunity to Plasmodium. Anopheles mosquitoes inoculated with CpG-ODN showed significant reduction of Plasmodium infection rate and intensity. Microarrays were used to profile transcription of fat-body from CpG-ODN-treated mosquitoes. Mosquitoes were dissected 18h after ODN inoculation (immediately before feeding). Batches of 20 to 30 fat bodies (abdomen without midgut, ovaries and malpighian tubule]) were dissected in cold DEPC-treated phosphate-buffered saline (PBS) and processed for RNA preparation. Mosquitoes treated with CpG-ODNs are less susceptible to Plasmodium infection. Transcription profile of fat body indicates that protection was associated with coagulation/wound healing, while melanization appears to be depressed.
