Project description:In this study, small RNA sequencing was performed on plasma samples from 10 polytraumatized patients (Injury Severity Score, ISS ≥ 16), who were stratified into two groups based on their initial Troponin T (TnT) levels at the emergency room. The high TnT group (n = 5) included patients with TnT concentrations > 50 pg/mL, while the low TnT group (n = 5) included those with TnT concentrations < 12 pg/mL. The aim of this dataset is to identify differentially expressed miRNAs associated with elevated TnT levels, a marker of cardiac injury in trauma patients. Differential expression analysis revealed several candidate miRNAs that may serve as potential biomarkers for cardiac dysfunction. This dataset highlights the diagnostic potential of miRNAs in post-trauma cardiac injury.

Project description:To understand molecular mechanisms of the joint effects of 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), both widely used ordnance compounds, we constructed a microarray consisting of 4,032 cDNA isolated from the earthworm Eisenia fetida using the suppressive subtractive hybridization technique. Worms were exposed to TNT-, RDX-, or TNT+RDX-spiked soil for 28 days (TNT 50 mg/kg, RDX 30 mg/kg). Keywords: Combined toxicity of TNT and RDX to earthworm (Eisenia fetida)

Project description:Cells undergo a major epigenome reconfiguration when reprogrammed to human induced pluripotent stem cells (hiPS cells). However, the epigenomes of hiPS cells and human embryonic stem (hES) cells differ significantly, which affects hiPS cell function. These differences include epigenetic memory and aberrations that emerge during reprogramming, for which the mechanisms remain unknown. Here we characterized the persistence and emergence of these epigenetic differences by performing genome-wide DNA methylation profiling throughout primed and naive reprogramming of human somatic cells to hiPS cells. We found that reprogramming-induced epigenetic aberrations emerge midway through primed reprogramming, whereas DNA demethylation begins early in naive reprogramming. Using this knowledge, we developed a transient-naive-treatment (TNT) reprogramming strategy that emulates the embryonic epigenetic reset. We show that the epigenetic memory in hiPS cells is concentrated in cell of origin-dependent repressive chromatin marked by H3K9me3, lamin-B1 and aberrant CpH methylation. TNT reprogramming reconfigures these domains to a hES cell-like state and does not disrupt genomic imprinting. Using an isogenic system, we demonstrate that TNT reprogramming can correct the transposable element overexpression and differential gene expression seen in conventional hiPS cells, and that TNT-reprogrammed hiPS and hES cells show similar differentiation efficiencies. Moreover, TNT reprogramming enhances the differentiation of hiPS cells derived from multiple cell types. Thus, TNT reprogramming corrects epigenetic memory and aberrations, producing hiPS cells that are molecularly and functionally more similar to hES cells than conventional hiPS cells. We foresee TNT reprogramming becoming a new standard for biomedical and therapeutic applications and providing a novel system for studying epigenetic memory.

Project description:To understand molecular mechanisms of the chronic, sublethal toxicity of 2,4,6-trinitrotoluene (TNT), a widely used ordnance compound of public concerns, we constructed a microarray consisting of 4,032 cDNA isolated from the earthworm Eisenia fetida using the suppressive subtractive hybridization technique. Worms were exposed to a gradient of TNT-spiked soil for 28 days. Based on the reproduction response to TNT, four treatments, i.e., control, 7, 35 and 139 ppm, were selected for gene expression studies. Keywords: Sublethal toxicity of TNT (dose-response) to earthworm (Eisenia fetida)

Project description:Tunneling NanoTubes (TNTs) are membrane conduits that mediate long distance intercellular crosstalk in several organisms and play vital roles during development, pathogenic transmission and cancer metastasis. However, the molecular mechanisms of TNT formation and function remain poorly understood. The protein MSec is essential for TNT formation in multiple cell types. We identified a novel interaction of MSec with the endoplasmic reticulum chaperone ERp29. ERp29 depletion in mammalian cells led to a significant reduction in TNT formation, while its over-expression induced TNT formation, but strictly in an MSec-dependent manner. ERp29 stabilized MSec protein levels but not its mRNA levels, and the chaperone activity of ERp29 was required for maintaining MSec protein stability. Our study implicates MSec as a new target of ERp29 and reveals an indispensable role for the endoplasmic reticulum in the biogenesis of TNTs, thus suggesting new modalities for regulating TNT numbers.
