Expression data: Venous malformation-causative TIE2-mutations mediate an AKT-dependent decrease in PDGFB

Project description:Comparison of transcriptional profiles of human umbilical vein endothelial cells (HUVECs) expressing wild-type vs. VM-causative mutant forms of TIE2/TEK. The effects of the most common Venous Malformation-causative mutations in the endothelial cell tyrosine kinase receptor: R849W and L914F, were tested. 743 genes were differentially expressed across the four groups. The 80 genes distinguishing between L914F and wild-type TIE2-expressing HUVECs were analyzed in greater detail. 3 batches each of: non-transfected, and wild-type TIE2, R849W-TIE2, and L914F-TIE2 overexpressing HUVECs were compared by exon-array profiling.

IgG4-ROD and orbital MALT lymphoma

Project description:The molecular pathogenesis of orbital lymphoproliferative disorders, such as immunoglobulin G4-related ophthalmic disease (IgG4-ROD) and orbital mucosa-associated lymphoid tissue (MALT) lymphoma, remains essentially unknown. Differentiation between the two disorders, which is important since work-up and treatment can vary greatly, is often challenging due to the lack of specific biomarkers. Although miRNAs play an important role in the regulation of carcinogenesis and inflammation, the relationship between miRNA and orbital lymphoproliferative diseases remains unknown. A comprehensive analysis of 2,565 miRNAs was performed in biopsied specimens and serum of 17 cases with IgG4-ROD and 21 cases with orbital MALT lymphoma. We identified specific miRNA signatures, their miRNA target pathways, and network analysis associated with IgG4-ROD and orbital MALT lymphoma. Machine-learning analysis identified miR-202-3p and miR-7112-3p as the best discriminators of IgG4-ROD and orbital MALT lymphoma, respectively. In the tissue pathway, Longevity regulating pathway in IgG4-ROD and MAPK signaling pathway in orbital MALT lymphoma were most enriched by downregulated miRNAs. This is the first evidence of the miRNA profile in biopsied specimens and serum of patients with IgG4-ROD and orbital MALT lymphoma. These data will be useful for developing diagnostic and therapeutic interventions, as well as elucidating of these disorders.

Comprehensive circular RNA expression profiling with associated ceRNA network in orbital venous malformation.

Project description:PurposeOrbital venous malformation (OVM), the most common type of vascular malformation in adults, has a great impact on both visual and cosmetic factors. Circular RNAs (circRNAs) play important roles in various ophthalmological diseases; however, little is known about their function in the pathogenesis of OVM.MethodsWe obtained differentially expressed circRNAs, mRNAs, and miRNAs based on RNA sequencing of four OVM tissues and four normal orbital vascular tissues. The circRNA-mRNA coexpression network and circRNA-miRNA-mRNA and competing endogenous RNA (ceRNA) networks were constructed using miRanda software. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed to identify the up- and downregulated mRNAs in the circRNA-miRNA-mRNA ceRNA network.ResultsOverall, we identified 45 upregulated and 144 downregulated circRNAs, as well as 2,175 upregulated and 1,274 downregulated mRNAs and 156 upregulated and 168 downregulated miRNAs in OVM samples compared with normal orbital vascular tissues. The expression changes of mRNAs and circRNAs detected by quantitative real-time PCR (qRT-PCR) were in line with the RNA-seq results. Then, a ceRNA regulatory network was constructed with these differentially expressed circRNAs, mRNAs, and miRNAs. GO functional analysis revealed that most related biological processes involved extracellular matrix organization, positive regulation of actin nucleation, and so on, which were thought to be involved in the evolution of OVM. KEGG pathway analysis of upregulated mRNAs showed that mucin-type O-glycan biosynthesis, glycosaminoglycan degradation, and the PI3K (Gene ID: 5290; OMIM: 613089)-AKT (Gene ID: 207; OMIM: 114500) signaling pathway were all enriched in OVM samples.ConclusionsOur study provides novel insight into the regulatory mechanism of circRNAs, miRNAs, and mRNAs in the pathogenesis of OVM.

Comparison of miRNA expression profile between arterial plasma and venous plasma

Project description:Circulating microRNAs (miRNAs) presented in venous plasma have recently been demonstrated as powerful biomarkers for the diagnosis and prognostic prediction of complex diseases like cancer. Nevertheless, those presented in arterial plasma have been ignored based on the assumption that the miRNA profiles in arterial and venous plasma would be identical. Here, we disputed this intuitive assumption by comparing arterial and venous plasma miRNA expression profiles from male rats using microarray technique. Though the microRNA profiles were largely similar, a considerable number of miRNAs showed significant differential expression, including 10 arterial highly expressed miRNAs and 14 venous highly expressed miRNAs. The differentially expressed miRNAs were validated by qRT-PCR. We performed computational analysis of the function enrichment and disease association of these miRNAs and their targets. Our analysis also suggested significant correlations between plasma miRNA expression and tissue miRNA expression. Four arterial highly expressed miRNAs showed enriched expression in specific tissues and thus could serve as novel biomarker candidates.
