Project description:To study the effects of miR--210 on 293T cells and hypoxia response, we used the CRISPR/Cas9 system to knockout (KO) the human miR-210 gene in 293T cells. We then added DMOG to mimic hypoxia condition and analyzed the RNA expression profile of wildtype (WT) and KO cells under normal and hypoxic conditions. DMOG treatment and RNA-seq were performed three times (experiment 1, 2, and 3).

Project description:MicroRNAs are small non-coding RNA species, some of which are playing important roles in malignancies. However, roles of miR-210 in cancer have yet to be unknown and controversial. Here, we found the expression level of miR-210 is downregulated in human esophageal squamous cell carcinoma and its cell lines. Additionally, we demonstrate that miR-210 inhibits cancer cell survival and proliferation through upregulation of cell death and induction of cell cycle arrest at G1/G0 and G2/M phases. However, candidate target mRNAs of miR-210 and the mechanism behind observed phenomena is uncertain. Then, we performed comprehensive gene expression analysis to identify candidate target mRNAs and understand their mechanisms.

Project description:Single microRNAs are usually associated with hundreds of putative target genes that can influence multiple phenotypic traits in Drosophila, ranging from development to behaviour. We investigated the function of Drosophila miR-210 in circadian behaviour by misexpressing it within circadian clock cells. Manipulation of miR-210 expression levels in the PDF (pigment dispersing factor) positive neurons affected the phase of locomotor activity, under both light-dark conditions and constant darkness. PER cyclical expression was not affected in clock neurons, however, when miR-210 was up-regulated, a dramatic alteration in the morphology of PDF ventral lateral neuron (LNv) arborisations was observed. The effect of miR-210 in shaping neuronal projections was confirmed in vitro, using a Drosophila neuronal cell line. A transcriptomic analysis revealed that miR-210 overexpression affects the expression of several genes belonging to pathways related to circadian processes, neuronal development, GTPases signal transduction and photoreception. Collectively, these data reveal the role of miR-210 in modulating circadian outputs in flies and guiding/remodelling PDF positive LNv arborisations and indicate that miR-210 may have pleiotropic effects on the clock, light perception and neuronal development.

KYSE-170 cells were transfected with oligoribonucleotides for miR-210 or ncRNA (Ambion, Austin, TX) using Hiperfect (Qiagen, Valencia, CA) according to the provider’s protocol for overexpression. Total RNA was extracted by the acid guanidinium thiocyanate-phenol-chloroform method and was labeled and prepared for hybridization to human Oligo chip 25k (Toray, Kamakura, Japan) using standard methods.

Project description:To identify putative novel specific targets of miR-34a, miR-122, miR-206 and miR-210, we overexpressed these miRNAs in human Hela cells by transfecting them with synthetic pre-miRNAs or a synthetic “negative” pre-miRNA as control (miR-Neg1). RNA samples were harvested at 48 hours post-transfection and 2 independent experiments were carried out.

Project description:Compulsory expression of miR-210 in normal endometrial stromal cells directed the induction of cell proliferation and vascular endothelial growth factor production, and the inhibition of apoptosis in through signal transducer and activator of transcription 3 (STAT3) activation. Accumulating evidence suggests that microRNAs play definite roles in the pathogenesis of endometriosis. The objective of the study was to determine the role of miR-210, one of the upregulated microRNA in endometriotic cyst stromal cells, in the pathogenesis of endometriosis. Downstream targets of miR-210 were identified by Compulsory expression of miR-210 in normal eutopic endometrial stromal cells, a global mRNA microarray technique, and Ingenuity pathways analysis.

Project description:MicroRNAs (miRNAs) are small non-protein-coding RNAs that are incorporated into the RNA-induced silencing complex (RISC) and inhibit gene expression by regulating the stability and/or the translational efficiency of target mRNAs. Previously, we demonstrated that miR-210 is a key player of endothelial cell (EC) response to hypoxia, modulating EC survival, migration and ability to form capillary like-structures. Moreover, the receptor tyrosine kinase ligand Ephrin-A3 was identified as one functionally relevant target. Since each miRNA regulates hundreds of mRNAs, different approaches were combined to identify new miR-210 targets: a Using target prediction software, 32 new miR-210 potential targets were identified. b The proteomic profiling of miR-210 over-expressing ECs identified 11 proteins that were specifically inhibited by miR-210, either directly or indirectly. c Affymetrix based gene expression profiles identified 51 genes that were both down-modulated by miR-210 over-expression and de-repressed when miR-210 was blocked. Surprisingly, only few genes identified either by proteomics or transcriptomics were recognized as miR-210 targets by target prediction algorithms. However, a low-stringency pairing research revealed enrichment for miR-210 putative binding sites, raising the possibility that these genes were targeted via non-canonical recognition sequences. To clarify this issue, miR-210-loaded RISC was purified by immuno-precipitation along with its mRNA targets. The presence of Ephrin-A3 mRNA in the complex validated this approach. We found that 32 potential targets were indeed enriched in miR-210-loaded RISC, and thus can be considered as genuine miR-210 targets. In keeping with this conclusion, we were able to further validate a sub-set of them by 3’UTR-reporter assays. Gene ontology analysis of the targets confirmed the known miR-210 activity in differentiation and cell cycle regulation, highlighting new functions such as involvement in RNA processing, DNA binding, development, membrane trafficking and amino acid catabolism. In conclusion, we validated a multidisciplinary approach for miRNAs target identification and indicated novel molecular mechanisms underpinning miR-210 role in EC response to hypoxia.
