miRNA changes in mild and moderate emphysema correlate with target gene expression in vivo and in vitro [target gene expression data]

Project description:To define the role of microRNAs and their mRNA targets in emphysema severity in COPD patients. We performed Agilent human miRNA oligo arrays (8x15K array, Part No. G4470A, Agilent Technologies) based on miRBase V9.1 on lung tissues from 9 mild and 20 moderate emphysema lungs obtained from patients undergoing curative resection for lung cancer. We identified 5 miRNAs and two of those were tested and validated technically using qRT-PCR. The predicted mRNA targets for the five miRNAs were identified in MSigDB using GSEA and their expression were negatively correlated in exvivo lung mRNA expression profile obtained from GEO datasets (GSE17770 and GSE1650). Increasing the expression of one of the miRNA target, miR-34c in BEAS-2B and HFL 1 cell lines resulted in the downregulation of 50 TargetScan and Pictar predicted targets of miR-34c.

Transcription profiling of human lung tissue from severe emphysema versus normal or mild emphysema human patients

Project description:Comparison of severely emphysematous tissue removed at lung volume reduction surgery to that of normal or mildly emphysematous lung tissue resected from smokers with nodules suspicious for lung cancer. Data obtained from the 18 patients with severe emphysema and 12 patients with mild/no emphysema. Research may provide insights into the pathogenetic mechanisms involved in chronic obstructive pulmonary disease (COPD).

Hippocampus-Cerebellum Axis Specific Transcriptomic Stratification to Discriminate Mild from Moderate TBI

Project description:The variations of psycho- and physiological deficits caused by TBI correlate with the degree of brain injury. However, the objective stratification of TBI is yet elusive. A modified closed-head injury Marmarou model was used based on the release of a 500 gram steel slug on top of the rat skull from a height of 100 cm or 120 cm to induce differential injury models for mild TBI and moderate TBI, respectively. The skull was covered by a helmet to mimic the warfighter’s condition in theater. The hippocampus was at the focal point of injury, and the cerebellum, was susceptible to diffused shock (secondary injury). The HC-CB axis coordinates visuomotor performance, which is known to be vulnerable to TBI. The rats that received moderate TBI showed deficient visuomotor performance by the Barnes maze test for longer time periods than those inflicted with mild TBI. The time resolved and HC-CB specific transcriptomic analysis focused on genes that enabled discrimination of mild from moderate TBI at 14d post injury which is equivalent to nearly 1.5 years of human lifetime. The functional analysis elucidated an active healing mechanism in the HC exposed to mild TBI. In contrast, moderate TBI caused delayed healing and active cell death in the HC. In conclusion, the graded brain injuries differentially implicated the HC-CB axis, despite the use of a helmet to reduce the impact. Time resolved functional dynamics informed the distinct consequences of mild vs. moderate TBI.

Mild, moderate and severe enterovirus 71 (EV71) isolates infection in human PBMCs

Project description:Hand, foot and mouth disease (HFMD), caused by enterovirus 71 (EV71), presents mild to severe disease, and sometimes fatal neurological and respiratory manifestations. However, reasons for the severe pathogenesis remain undefined. To investigate this, infection and viral kinetics of EV71 isolates from clinical disease (mild, moderate and severe) from Sarawak, Malaysia, were characterized in human rhabdomyosarcoma (RD), neuroblastoma (SH-SY5Y) and peripheral blood mononuclear cells (PBMCs). High resolution transcriptomics was used to decipher EV71-host interactions in PBMCs. Ingenuity analyses revealed similar pathways triggered by all EV71 isolates, although the extent of activation varied. Importantly, several pathways were found to be specific to the severe isolate, including triggering receptor expressed on myeloid cells 1 (TREM-1) signaling. Depletion of TREM-1 in EV71-infected PBMCs with peptide LP17 resulted in decreased levels of pro-inflammatory genes, and reduced viral loads for the moderate and severe isolates. Mechanistically, this is the first report describing the transcriptome profiles during EV71 infections in primary human cells, and the involvement of TREM-1 in the severe disease pathogenesis, thus providing new insights for future treatment targets.
