Project description:This pilot study enrolled 9 GWI (Gulf War Illness) cases identified from the Department of Veterans Affairs GWI registry, and 11 sedentary control veterans who had not been deployed to the Persian Gulf and were matched to cases by sex, body mass index (BMI) and age.<br>We exposed GWI patients and matched controls to an exercise challenge to explore differences in immune cell function measured by classic immune assays and gene expression profiling.

Project description:Gulf War Illness (GWI) is a diverse set of neurologic and systemic symptoms affecting many veterans deployed in the Persian Gulf War, but its etiology is unknown and treatment options are limited. Veterans with GWI were exposed to a variety of agents, including pyridostigmine bromide, used as prophylaxis against nerve agents, intranasal lipopolysaccharide (LPS) from desert sandstorms, and chronic unpredictable stress (CUS) from combat. Here, we investigated the gene expression effects of these three Gulf War-related exposures (GWE) in adult rat frontal cortex (FC) and lateral amygdala (LA) using Clariom S microarrays. We found 138 transcript clusters (TCs) in LA and 38 TCs in FC differentially expressed between the group with GWE (n=2) compared to naïve controls (n=3, FDR <10%). These TCs included genes involved in inflammation such as Fosb (pmin=1.02e-5) and Junb (pmin=1.13e-5). Gene ontology analysis found enrichment of differentially expressed genes in “T cell differentiation” (pmin=8.71e-5) and “response to organophosphorus” (pmin=1.74e-8), among other categories. Lastly, we found that prophylactic treatment with rosiglitazone, a PPAR- agonist, reduced gene expression changes associated with GWE (in LA: 115/138 [83.3%] TCs with reduced changes, χ2=61.33, p=4.82e-15). These results suggest our rat model of GWI is associated with gene expression changes related to neuroinflammation and that some of these molecular changes may be mitigated by rosiglitazone prophylaxis.

Project description:The Persian Gulf is a special habitat of marine sponges whose bacterial communities are under-investigated. Recently, next-generation sequencing technology has comprehensively improved the knowledge of marine sponge-associated bacteria. For the first time, this study aimed to evaluate the diversity of the Persian Gulf sponge-associated bacteria using tag pyrosequencing in Iran. In this study, 10 sponge samples from 6 different taxonomic orders were collected from the Persian Gulf using SCUBA diving. The diversity of the bacteria associated with the marine sponges was investigated using the 16S rRNA gene PCR-tagged pyrosequencing method. A total of 68,628 high-quality sequences were obtained and clustered at a 97% similarity into 724 unique operational taxonomic units (OTUs), representing 17 bacterial phyla. Cyanobacteria was the most abundant phylum in the sponges, followed by Proteobacteria, Chloroflexi, Acidobacteria, and Actinobacteria. Other phyla were detected as minor groups of bacteria. Bacterial community richness, Shannon, and Simpson indices revealed the highest diversity in sponge S11 (Dictyoceratida sp.) compared to other sponges. This study showed a diverse structure of bacterial communities associated with the Persian Gulf sponges. The dominance of Cyanobacteria may suggest an ecological importance of this phylum in the Persian Gulf sponges.

Project description:Intensive research in past two decades has uncovered the presence and importance of noncoding RNAs (ncRNAs), which includes microRNAs (miRs) and long ncRNAs (lncRNAs). These two classes of ncRNAs interact to a certain extent, as some lncRNAs bind to miRs to sequester them. Such lncRNAs are collectively called 'competing endogenous RNAs' or 'miRNA sponges'. In this study, we screened for lncRNAs that may act as miRNA sponges using the publicly available data sets and databases. To uncover the roles of miRNA sponges, loss-of-function experiments were conducted, which revealed the biological roles as miRNA sponges. LINC00324 is important for the cell survival by binding to miR-615-5p leading to the de-repression of its target BTG2 LOC400043 controls several biological functions via sequestering miR-28-3p and miR-96-5p, thereby changing the expressions of transcriptional regulators. Finally, we also screened for circular RNAs (circRNAs) that may function as miRNA sponges. The results were negative at least for the selected circRNAs in this study. In conclusion, miRNA sponges can be identified by applying a series of bioinformatics techniques and validated with biological experiments.
