Plasma extracellular vesicle miR-483-3p and let-7d-3p as potential biomarkers for sepsis

Project description:Recent literature has documented the use of microRNAs (miRNAs) from circulating extracellular vesicles (EVs) as biomarkers for a plethora of diseases. The aim of this prospective study was to identify the diagnostic value of plasma EV-miRNAs in sepsis.Sepsis patients and healthy controls were matched for age and gender. EVs were separated from plasma of sepsis patients at admission as well as healthy controls. The expression of EV-miRNAs was evaluated by microarray and qRT-PCR.

Project description:HaCaT human keratinocytes were transfected with pre-miR-483-3p or pre-miR-NC. RNA samples were harvested 48h post-transfection and mRNA profiles were determined with pan genomic arrays. Two biological replicates were performed for each comparison. Data were normalized using a dye-swap method.

miRNA-483-3p overexpression unleashes invasive growth of metastatic colorectal cancer via NDRG1 downregulation and ensuing activation of the ERBB3/AKT axis

Project description:Colorectal cancer is a prevalent disease that is the third most common cause of cancer-associated death globally. The genetic mechanisms underlying tumor aggressiveness in colorectal cancer require further elucidation. Taking advantage of a large panel of human metastatic colorectal cancer xenografts and matched stem-like cell cultures (m-colospheres), we show here that overexpression of miRNA-483-3p, encoded by a frequently amplified gene locus encompassing IGF2, confers an aggressive phenotype. Following ectopic overexpression of miRNA-483-3p, m-colospheres displayed (i) increased proliferative response to exogenous EGFR family ligands EGF and neuregulin 1; (ii) increased spontaneous and growth factor-induced invasiveness and epithelial-mesenchymal transition (EMT); and (iii) enhanced stem-cell frequency and resistance to differentiation. Transcriptomic analyses and functional validation found that miRNA-483-3p directly targets NDRG1, a known metastasis suppressor responsible for downregulation of the EGFR family. As a result, induced or endogenous miRNA-483-3p overexpression associated with stimulation of the signaling pathway triggered by ERBB3, including AKT and GSK3β, which is responsible for EMT transcription factor activation. Consistently, treatment of miRNA-483-3p-overexpressing m-colospheres with selective ERBB3 antibodies counteracted their proliferative and invasive phenotype. The pro-malignant role of miRNA-483-3p was further corroborated by analysis of human colorectal tumors, where miRNA-483-3p expression levels directly correlated with expression of EMT transcription factors and poor prognosis, and downregulation of miRNA-483-3p, which prevented invasion of tumors formed by m-colosphere transplantation. These results unveil a previously unrecognized link between miRNA-483-3p, NDRG1, and ERBB3-AKT signaling, which can directly support colorectal cancer invasion and is amenable to therapeutic targeting.

Extracellular vesicle microRNA biomarkers of late post-sepsis survivors

Project description:Sepsis is a life-threatening condition with high hospital mortality. Elevated mortality has also been observed in patients after hospital discharge, associated with post sepsis syndrome (PSS), causing systemic impairments and reduced life quality. The etiology of PSS is still not completely known but certainly involves inflammation. Extracellular vesicles (EV) are recognized as a notable mechanism of intercellular communication in inflammatory processes. It has been reported that EV microRNA (miRNA) production patterns during the acute phase of the disease may persist until after sepsis resolution and are associated with PSS. Methods: We employed mass spectrometry and qPCR to characterize the protein and miRNA composition of plasma-derived EVs of 35 patients during sepsis-related hospitalization and after discharge (post-sepsis) for up to three years. Findings: Fifteen differentially expressed EVs miRNAs (DEMiRs) were identified in septic patients compared to the control group. Predictive analyses revealed that these DEMiRs could influence inflammation by modulating pathways mediated by the activation of NF-κB, STAT3, and TLR4. Thirteen miRNAs (-15b-5p, -16-5p, -20a-5p, -25-3p, -27a-3p, -29a-3p, -30d-5p, -93-5p, -146a-5p, -148a -3p, -191-5p, -195-5p, -223-3p) were downregulated in the death group compared to the survivor group and are candidates for serving as prognostic markers of survival in the Intensive Care Unit. The expression of 11 miRNAs (-15b-5p, -16-5p, -21-5p, -25-3p, -27a-3p, -29a-3p, -30d-5p, -93-5p, -146a-5p -195- 5p and -223-3p) was lower one year after ICU discharge than the control group. Interpretation: The miRNAs identified in the present study represent potential biomarkers for the survival prognosis of post-sepsis patients.

Transcriptome data of miR-483 overexpression in human pulmonary arterial endothelial cells

Project description:MicroRNA-483 (miR-483) regulate endothelial function through inhibition expression of connective tissue growth factor (CTGF). Endothelial dysfunction is involved in the pathogeneis of pulmonary arterial hypertension (PAH). We investigated the role of miR-483 overexpression on human pulmonary arterial endothelial cells (hPAECs) through comparing the transcriptome file of hPAECs transfected with miR-483 -3p and -5p mimic and with control mimic. Gene ontology analysis showed that several PAH-associated signaling pathways were regulated by miR-483, including transforming growth factor-β signaling, Wnt signaling and inflammatory response, cell adhesion, response to hypoxia, apoptotic processes, oxidative reduction processes and negative regulation of cell migration and proliferation.

miR-483 overexpression in human sarcoma cell line MHH-ES-1.

Project description:miRNA abnormalities are increasingly relevent to cancer development, We used microarrays to detail the global programme of gene expression upon miR-483 overexpression in sarcoma cell line MHH-ES-1. MHH-ES-1 cells were transfected with miR-483-5p, -3p or scrambled control mimics and then harvested 48 hours after to isolate total RNAs using Trizol reagent (Invitrogen). Total RNA was converted to cRNA probes using the BioArray High Yield Transcript Labeling Kit (ENZO diagnostics), and hybridized to Affymetrix GeneChip human HG-U133ver2+ 3’-mRNA expression microarray chips using protocol EukGEs2v4 on the GeneChip Fluidic Station.
