MRNA profiling in enterovirus type 71-infected SH-SY5Y cells after transfection with miR-1246 inhibitor

ABSTRACT: Today, the pathogenesis of human enterovirus type 71 (HEV71) infection in human central neural system remains unclear. HEV71 is the major pathogen of hand-foot-and-mouth disease (HFMD), and has been associated with severe neurological disease and even death in infants and young children. We employed the human whole genome microarray analyze the mRNA profiling in human neuroblastoma cells SH-SY5Y infected with HEV71 after transfection. Firstly, SH-SY5Y cells were transfected wtih miR-1246 inhibitor and negtive control respectively using HiPerFect Transfection Reagent according to the manufacturer’s instructions. Then the cells were infected with HEV71 after transfection. After 12 hours infection, the cells were harvested to microarray analysis. The results showed the altered expression of mRNAs including up-regulated genes and down-regulated genes. Overall, this finding will help to understand the functional genes in HEV71-infected human neuroblastoma cells and miR-1246-virus-host interaction. SH-SY5Y cells were transfected wtih miR-1246 inhibitor and negtive control respectively using HiPerFect Transfection Reagent according to the manufacturer’s instructions. Then the cells were infected with HEV71 after transfection. After infection, the cells were harvested to microarray analysis. Total RNA of cells infected with HEV71 was extracted using the TRIZOL Reagent according to the manufacturer's instructions. Gene-expression profiling was performed for each pooling RNA sample separately on the GeneChip_ Porcine Genome Array at CapitalBio Corporation (Beijing, China).

Gene expression microarray analysis following siRNA knockdown of T-UC.300A

Project description:SH-SY5Y cells were transfected with an siRNA against T-UC.300A (final concentration 50nM) or negative control siRNA (Dharmacon Negative Control #1, final concentration 50 nM) using the transfection reagent Lipofectamine (Invitrogen). Media was changed after 24hrs. RNA was extracted 120hrs after transfection. Gene expression microarray analysis was carried out using Roche NimbleGens 4x72K Homo Sapiens gene expression array.

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.

Expression profiling of death-related genes in ZIKV-infected SH-SY5Y cells

Project description:Analysis of death triggering pathways activated by experimental Zika virus infection in SH-SY5Y cells by expression profiling of 42 genes related to survival, anti-apoptotic and proapoptotic responses, and death receptors pathway, and 06 endogenous control genes. Commercially available neuroblastoma SH-SY5Y cells were grown in vitro, experimentally infected with Zika virus (MOI 0.5), and MOCK- and ZIKV-infected cells were harvested at 1 and 2 days post-infection. We used TaqMan ™ Array Human Apoptosis via Death Receptors (Thermo Fisher Scientific, MA, USA) to quantitate gene expression during ZIKV infection in SH-SY5Y cells.

Genome-wide analysis of miRNA-associated transcriptome profiles in multiple cell models

Project description:Schizophrenia-associated miRNA were bidirectionally modulated in HEK-293, HeLa, and SH-SY5Y cell models. Results provide important insights into the current understanding of miRNA function in various cellular environments. Total RNA was obtained from HEK-293, HeLa, and SH-SY5Y cells at 24hrs post-transfection with either synthetic miRNA (miR overexpression) or anti-miR inhibitor (miR inhibition) oligonucleotides.

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.

Gene expression during neuronal differentiation in two subtypes of SH-SY5Y

Project description:Background: SH-SY5Y cells exhibit a neuronal phenotype when treated with all-trans retinoic acid (RA), but the molecular mechanism of activation in the signaling pathway mediated by phosphatidylinositol 3-kinase (PI3K) is not sufficiently understood. To shed new light on the mechanism, we comprehensively compared the gene expression profiles between SK-N-SH cells and two subtypes of SH-SY5Y cells (SH-SY5Y-A and SH-SY5Y-E), each of which showed a different phenotype during RA-mediated differentiation. Results: SH-SY5Y-A cells differentiated in the presence of RA, whereas RA-treated SH-SY5Y-E cells required additional treatment with brain-derived neurotrophic factor (BDNF) for full differentiation. In combination with perturbation using a PI3K inhibitor, LY294002, we identified 386 genes and categorized them into two clusters dependent on the PI3K signaling pathway during RA-mediated differentiation in SH-SY5Y-A cells. Transcriptional regulation of the gene cluster was greatly reduced in SK-N-SH cells or partially impaired in SH-SY5Y-E cells in coincidence with a defect in the neuronal phenotype of these cell lines. Additional stimulation with BDNF induced a set of neural genes which were down-regulated in RA-treated SH-SY5Y-E cells but were abundant in the differentiated SH-SY5Y-A cells. Conclusions: We identified the gene clusters controlled by PI3K- and TRKB-mediated signaling pathways during differentiation in two subtypes of SH-SY5Y cells. TRKB-mediated bypass pathway compensates for the impaired neural functions generated by defects in several signaling pathways including PI3K in SH-SY5Y-E cells. The expression profiling data are useful for further studies to elucidate the signal transduction-transcriptional network including PI3K and/or TRKB. Keywords: Cell type comparison, time course
