Transcriptomic analysis of SH-SY5Y cells in response to enterovirus type 71 infection

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 transcriptome profiling inhuman neuroblastoma cells SH-SY5Y infected with HEV71. The results showed that HEV71 infection lead to altered expression of 161 human mRNAs including 74 up-regulated genes and 87 down-regulated genes. Then we found that the possible roles of the differentially regulated mRNAs in selected pathways including cell cycle/proliferation, apoptosis, and cytokine/chemokine responses by Bioinformatic analysis. Furthermore, we validated the microarray results by real-time RT-PCR with high identity. Overall, our results provided fundamental information about host response to HEV71 infection in human neuroblastoma cells, and this finding will help to understand the pathogenesis of HEV71 infection and virus-host interaction. 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 (Affymetrix) at CapitalBio Corporation (Beijing, China) in which GeneChip microarray service was certificated by Affymetrix.

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

Project description: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.

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.

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.

CHD5 is required for neurogenesis and has a dual role in facilitating gene expression and Polycomb gene repression

Project description:The chromatin remodeler CHD5 is expressed in neural tissue and is frequently deleted in aggressive neuroblastoma. Very little is known about the function of CHD5 in the nervous system or its mechanism of action. Here we report that depletion of Chd5 in the developing murine neocortex blocks neuronal differentiation and leads to an accumulation of undifferentiated progenitors. CHD5 binds a large cohort of genes and is required for facilitating the activation of neuronal genes. It also binds a cohort of Polycomb targets and is required for the maintenance of H3K27me3 on these genes. Interestingly, the chromodomains of CHD5 directly bind H3K27me3 and are required for neuronal differentiation. In the absence of CHD5, a subgroup of Polycomb-repressed genes becomes aberrantly expressed. These findings provide new insights into the regulatory role of CHD5 during neurogenesis and suggest how inactivation of this candidate tumor suppressor might contribute to neuroblastoma. Examination of genome-wide binding/occupancy of CHD5 in the SH-SY5Y cell line

The proteome of neuroglobin-overexpressing SH-SY5Y neuroblastoma cells

Project description:Neuroglobin (NGB) is an oxygen-binding globin expressed in vertebrates mainly in the central and peripheral nervous system, but also in extra-neuronal cells. NGB is involved in oxygen transport, storage, and homeostasis. The role hypothesized for this globin is in fact related to neuroprotection against oxidative stress. Also, NGB is functionally and physically associated to mitochondria, possibly playing a role in ATP production and regulation. NGB actually exerts its function upon up-regulation. Thus, NGB-overexpressing SH-SY5Y neuroblastoma cells (NGB-FLAG) were analyzed by shotgun label-free quantitative proteomics in comparison with control cells (CTRL).
