Project description:Tuberculosis-associated Immune Reconstitution Inflammatory Syndrome (TB-IRIS) is a common complication in HIV-TB co-infected patients receiving combined antiretroviral therapy (cART). While monocytes/macrophages play major roles in both HIV- and TB-infection individually, a putative contribution of monocytes to the development of TB-IRIS remains unexamined. We performed a genome-wide array analysis on MOs purified from peripheral blood mononuclear cells (PBMCs) obtained before initiation of combined antiretroviral therapy (cART) to verify whether the transcriptome of MOs was already significantly modulated (even before receiving cART) in HIV+/TB+ patients who later developed TB-IRIS compared to control HIV+/TB+ patients who did not develop the complication . The subjects under study included a subset of 18 TB-IRIS patients and controls matched for age, gender and CD4 count.

Project description:Here, we have developed a novel methodology called IRIS (Imaging Reconstruction using Indexed Sequencing) that enables cost-effective spatial transcriptomics profiling without relying on optical imaging. Through neighborhood interaction-based reconstruction, IRIS allows extensive analysis of large tissue sections and many replicates with adjustable mapping resolution at only a fraction of the cost of other commercial platforms. With the IRIS platform, we reconstructed a large area spatial area with two whole mouse brain coronal sections. Moreover, we also created a spatially resolved transcriptome atlas of the mouse brain and identified aging-associated changes in gene expression and spatial organization across various brain cell types. Further analysis of cell-cell interaction changes identified aging-associated foci in white matter regions enriched with inflammatory subtypes of microglia and oligodendrocytes. Overall, the IRIS methodology cost-effective and ease-of-use approach makes it broadly applicable to the studies of spatial gene expression changes in various systems.

Project description:Tuberculosis Immune Reconstitution Inflammatory Syndrome (TB-IRIS) frequently complicates combined anti-retroviral therapy (ART) and anti-tubercular therapy in HIV-1 co-infected tuberculosis (TB) patients. The immunopathological mechanism underlying TB-IRIS is incompletely defined. Differential transcript abundance in PBMC from IRIS and control patients stimulated with heat killed H37Rv was determined by microarray Blood samples were collected during longitudinal observational studies of TB-IRIS patients and controls (both groups HIV-infected patients placed on antiretroviral treatment). PBMC were stimulated with heat killed H37Rv and RNA extracted.

Project description:Transcriptome sequencing of non-model organisms is valuable resource of the genetic basis of ecological-meaningful traits. The Royal Irises, Iris section Oncocyclus (Iris: Iridaceae, order Asparagales), are a Middle-East group of species in the course of speciation. The species are characterized with extremely large flowers, a huge range of flower colors and a unique pollination system. The Royal Irises, which are a symbol of conservation in the Middle-east, serve as a model for evolutionary processes of speciation and plant ecology. However, there are not sufficient transcriptomic and genomic data for molecular characterization. Thus, it is necessary to generate massive transcript sequences for functional characterization and molecular marker development for the Royal Irises. The Iris transcriptome sequencing provides valuable resource for studying adaptation-associated traits in this non-model plant. Although intensive eco-evolutionary studies, this is the first reported transcriptome for the Royal Irises. The data available from this study will facilitate gene discovery, functional genomic studies and development of molecular markers in irises, and will provide genetic tools for their conservation.

Project description:The aim of this study was to identify anti-obesity peptide from Allomyrina dichotoma (A. dichotoma) and investigate the biochemical signaling pathway. For that, A. dichotoma larvae was hydrolyzed enzymatically, and further purified by using tangential flow filtration and consecutive chromatographic method. Finally, anti-obesity peptide was obtained, and their sequences identified as Gln-Ile-Ala-Gln-Asp-Phe-Lys-Thr-Asp-Leu (EIA10). EIA10 prevented adipocyte differentiation in vitro and was further investigated the mechanism underlying the effects in vivo. Our results indicated that EIA10 reduced body weight gain, organ weight and adipose tissue volume. Glucose tolerance and insulin resistance in high fat diet-fed obese mice significantly improved after EIA10 administration for four weeks. In addition, EIA10 significantly decreased TC and LDL, increased HDL, improved lipid metabolism, and downregulated mRNA and protein expression of transcription factors implicated in lipid adipogenesis. Taken together our results suggest that EIA10 from possessed potential for the treatment and prevention of obesity.

Project description:Patients with HIV-associated TB are known to experience systemic hyperinflammation, clinically known as immune reconstitution inflammatory syndrome (IRIS), following the commencement of antiretroviral therapy (ART). No prognostic markers or biomarkers have been identified to date and little is known about the mechanism mediating the hyperinflammation. We recruited a prospective cohort of 63 patients with HIV-associated TB, 33 of whom developed TB-IRIS. Of which transcriptomic profiling was performed using longitudinal whole blood RNA samples from 15 non-IRIS and 17 TB-IRIS patients. Transcriptomic signatures that distinguish patients who would eventually develop IRIS were identified as early as week 0.5 (2-5 days post-ART) and predicted a downstream activation of proinflammatory cytokines. At the peak of IRIS (week 2), transcriptomic signatures were overrepresented by innate receptor signaling pathways including toll-like receptor, IL-1 receptor and TREM-1.

Project description:Previous Genome-wide association studies (GWASs) have identified susceptibility loci of primary angle closure glaucoma (PACG), but applicating these findings is difficult. Although shallow anterior chamber depth (ACD) and short axial length (AL) are characteristic phenotypes of PACG, current GWAS variants do not show any correlation with these features, calling for the identification of more risk factors . Here, thicker and enlarged iris was identified as a significant independent risk factors. By employing allelic-specific STARR-seq and assay for transposase-accessible chromatin using sequencing (ATAC-seq), we screened disease-related variants in linkage disequilibrium and identified 2 causative variants in iris. Alterations in these variants may contribute to the pathogenic iris phenotype by upregulating the expression of PLEKHA7 and C10orf53, potentially regulating PACG development and progression. Our efforts nominate the important role of iris and identify pathogenic SNP-target gene interactions for PACG, providing a potentially powerful approach for interpreting noncoding variation of diseases.
