miRNA profiling in HEV71-infected SH-SY5Y cells

Project description:MicroRNA (miRNA) has been highlighted in pathogen-host interactions, however, little is known about roles of miRNAs in neurological pathogenesis of human enterovirus 71 (HEV71) infections. In this study, the comprehensive miRNA expression profiling in HEV71-infected human neuroblastoma SH-SY5Y cells were performed to identify cellular miRNAs response to HEV71. A total of 69 miRNAs were differentially expressed in HEV71-infected SH-SY5Y cells compared to non-infected cells. These findings provide new information on the miRNA and mRNA profiles in HEV71 infection, which may serve as a basis for further investigation into the biological functions of miRNAs in the neurological pathogenesis of HEV71 infections. Human neuroblastoma SH-SY5Y cells were infected with HEV71. After infection, the cells were harvested and extracted total RNA for miRNA profiling by hybridization on Affymetrix microarrays. A total of 69 miRNAs were differentially expressed inHEV71-infected SH-SY5Y cells compared to non-infected cells.

Functional investigation of miRNAs by characterization of SH-SY5Y cells overexpressing wild type or mutant miRNA genes

Project description:Genome wide mRNA and miRNA profiling was performed in SH-SY5Y cells stably overexpressing wild type or mutant MIR204 or MIR618. Mutants came from a large scale genetic screening of brain expressed miRNA genes in patients with schizophrenia or idiopathic generalized epilepsy and in control individuals. Based on enrichment of the variants with the schizophrenic or epileptic phenotype and based on impact prediction, two variants, one near MIR204 (rs7861254) and one in MIR618 (rs2682818) were selected for functional validation. Genome wide profiling of mRNA (micro-array) and mature miRNAs (small RNA sequencing, submitted to SRA) was performed in the created stable cells to assess the effect of the variants and to investigate the function of these miRNA genes. Micro-array analysis on HTA2.0 array was performed at AROS Applied Biotechnology, Denmark. SH-SY5Y cells (purchased from Sigma-Aldrich, catalog number: 94030304-1VL) were transduced with MIR204 or MIR618 wild type or mutant constructs. The stable cells were then split to obtain biological replicates and were cultured separately prior to total RNA extraction and micro-array analysis on the HTA2.0 array. For MIR204 analysis: 2 wt cells versus 3 mutant cells; for MIR618 analysis: 3 wt cells versus 3 mutant cells were used.

HSV-1 infection of neural system-derived cells, including SH-SY5Y and U87MG cells at 0, 4 and 10 hour post infection with an MOI of 0.01,to identify the differentially expressed miRNAs and perform pathway enrichment analysis using KEGG.

Project description:we employed human miRNA Microarray assay to identify differentially expressed (DE) miRNAs in response to HSV-1 infection of SH-SY5Y and U87MG cells. The significantly DE miRNAs existed in U87MG but not SH-SY5Y cells at 4 hours post-infection (hpi), HSV-1 latency-associated transcripts (LAT)-derived miRNAs were not abundantly expressed in both SH-SY5Y and U87MG cells, meanwhile, HSV-1 replication was significantly inhibited in U87MG but not SH-SY5Y. Pathway enrichment analysis results showed that target genes of 10 down-regulated DE miRNAs were significantly enriched in Janus kinase-signal transducers and activator of transcription (JAK-STAT) signaling and Herpes simplex virus infection in U87MG cells at 4 hpi. These results indicated that DE of miRNAs may contribute to the HSV-1 replication inhibition in U87MG cells and also may be linked to HSV-1 latency in neurons.

The effect of knock-down of neuroblastoma associated lncRNA on transcriptome

Project description:As part of functional characterization of neuroblastoma assocated lncRNA, we performed its knock-down in neuroblastoma cell line SH-SY5Y, which resulted in modulation of expression levels of a set of genes involved in angiogenesis and inflammation, the hallmarks of metastatic cancer. SH-SY5Y cells were transfected with non-targeting siRNA control and two siRNAs targeting lncRNA BEHOT. Two days after transfection total RNA was isolated and hybridized to microarray, each sample was done in four replicas.

MicroRNA-664a-5p promotes neuronal differentiation of SH-SY5Y cells

Project description:MicroRNAs (miRNAs) belong to a class of small non-coding RNAs that play important roles in the transcriptional regulation of gene expression. A number of miRNAs are known to act as key regulator of diverse processes such as neuronal differentiation. In this study, we have attempted to identify novel miRNAs related to neuronal differentiation. 15 upregulated and 8 downregulated miRNAs were identified in SH-SY5Y cells treated with all-trans retinoic acid. We further showed that one of the upregulated miRNAs, miR-664a-5p promoted neuronal differentiation of SH-SY5Y cells. Herein, we report for first time the important role of miR-664a-5p in SH-SY5Y cells.
