Project description:Purpose: The goal of this study is to compare endothelial small RNA transcriptome to identify the target of OASL under basal or stimulated conditions by utilizing miRNA-seq. Methods: Endothelial miRNA profilies of siCTL or siOASL transfected HUVECs were generated by illumina sequencing method, in duplicate. After sequencing, the raw sequence reads are filtered based on quality. The adapter sequences are also trimmed off the raw sequence reads. rRNA removed reads are sequentially aligned to reference genome (GRCh38) and miRNA prediction is performed by miRDeep2. Results: We identified known miRNA in species (miRDeep2) in the HUVECs transfected with siCTL or siOASL. The expression profile of mature miRNA is used to analyze differentially expressed miRNA(DE miRNA). Conclusions: Our study represents the first analysis of endothelial miRNA profiles affected by OASL knockdown with biologic replicates.

Project description:Sequencing of relevant miRNAs was performed in si-uc003pxg.1-transfected HUVECs and control HUVECs. Fourteen upregulated and 5 downregulated miRNAs were selected based on P-values and fold change values. And cell experiments also showed that miR-25-5p was significantly upregulated in HUVECs compared to normal samples following uc003Pxg.1 knockdown. The luciferase activities of the miR-25-5p mimic + uc003pxg.1 wt group were significantly decreased compared with those of the miR-25-5p mimic + uc003pxg.1 mut group, while there was no significant difference in the luciferase activities between the miR-25-5p mimic and NC samples in the mutant group. This result indicated that uc003pxg.1 interacts with miR-25-5p. This study provides a theoretical basis for the study of the molecular mechanism of uc003pxg.1 in HUVECs.

Project description:Purpose: The goal of this study is to compare endothelial transcriptome affected by OASL knockdown under basal or stimulated conditions by utilizing RNA-seq. Methods: Endothelial mRNA profilies of siCTL or siOASL transfected HUVECs were generated by illumina sequencing method, in duplicate. Following an optimized data analysis workflow, RNA sequence reads were counted using StringTie-2.1.3b and used to identify genes differentially expressed between siCTL- and siOASL-transfected HUVECs treated with or without TNFα and IFNγ. Results: DESeq2 was used to identify genes differentially expressed between siCTL- and siOASL-transfected HUVECs under basal or stimulated conditions. Genes showing <10 read counts total were pre-filtered. Conclusions: Our study represents the first analysis of endothelial mRNA affected by OASL knockdown with biologic replicates, generated by RNA-seq.

Project description:Purpose: In recent years, research has revealed the role of microRNAs (miRs) as important regulators of endothelial function. Notably, miR-125a is upregulated in the blood of patients with acute vascular diseases. Since miRNAs act out their function in networks, we aimed at investigating the presence of a miR-125a-related network regulating the endothelial barrier. Method: We investigated transcriptional changes of human umbilical cord endothelial cells (HUVEC) after miR-125a overexpression in an acute inflammatory in-vitro setting using Next Generation Sequencing. Briefly, primary HUVECs from five different donors were transfected either with hsa-miR-125a-5p or negative control (NC). After transfection HUVECs were cultivated for 18 hours and stimulated with TNF (25 ng/ml) for additional 6 hours. We compared the following groups: NC (18047-0001, 18047-0002, 18047-0003, 18047-0004, 18047-0005) versus miR125a: (18047-0006, 18047-0007, 18047-0008, 18047-0009, 18047-0010) Results: MiR-125a overexpression in inflammatory activated HUVECs significantly altered gene expression of 468 genes (FC: +1.25 to -1.25 p<0.01). We found eight potential miR-125a direct target genes involved in endothelial barrier function.

Project description:MicroRNAs (miRNAs) are small (18-22 nucleotides), non-coding RNAs that suppress the translation of target mRNAs by binding to their 3` untranslated region, and regulate gene networks, helping to control cell function and phenotype. Recently, the existence of extracellular miRNAs enclosed in exosomes has raised the possibility that they play an important role in cell-cell communication. The goals of this study were to elucidate whether or not miRNAs secreted from neoplastic cells transfer into endothelial cells and works functionally active in the recipient cells. In the present study, we investigated the interaction of a leukemia cell line (K562) and human umbilical vein endothelial cells (HUVECs) using a non-contact co-culture system, and assess the expression profiles of intercellular and extracellular miRNAs in HUVECs and K562 cells using Taqman MicroRNA Array v2.0 (Applied Biosystems, Bedford, MA). We compared the miRNA expression profiles between 1) K562 cells or HUVECs; 2) intercellular and extracellular; 3) mono-culture medium and co-culture medium.

We compared the miRNA expression profiles between 1) K562 cells or HUVECs; 2) intercellular and extracellular; 3) mono-culture medium and co-culture medium. K562 cells and HUVECs were non-contact co-cultures using Transwell (Corning, pore size: 0.45µm) for 24 hr. The culture medium was collected and filtered through a 0.45 µm PVDF filter (Millipore, Billerica, MA). The intercellular and extracellular RNAs were isolated from K562 cells, HUVECs and each culture medium using the mirVana PARIS kit (Ambion, Austin, TX). The expression profile was determined using the Human Taqman MicroRNA Arrays A (Applied Biosystems). QRT-PCR was carried out on an Applied Biosystems 7900HT thermal cycler. The thermal cycling conditions consisted of 10 min at 95°C, followed by 40 cycles at 92°C for 15 s and 60°C for 1 min.

Project description:Brain metastasis (BM) can affect up to 25% of non-small cell lung cancer (NSCLC) patients during their lifetime. Efforts to characterize patients that will develop BM have been fairly disappointing. Small non-coding microRNAs (miRNAs) regulate the expression of target mRNAs by repressing their translation or regulating their sequence-specific degradation. miRNAs play a role in regulating a variety of targets and, consequently, multiple pathways, which makes them a powerful tool to be exploited for early detection of disease, risk assessment, and prognosis. In this study, we investigated miRNAs that may serve as biomarkers to differentiate between NSCLC patients with and without BM. miRNA microarray profiling was performed on samples from clinically matched NSCLC from patients with BM (BM+) and without BM (BM-). miR-328 and miR-330-3p were able to correctly classify BM+ vs. BM- patients. Gene expression analysis comparing NSCLC parental and stably transfected miR-328 cells identified several significantly differentially-expressed genes, whose expression may be directly or indirectly regulated by miR-328.
