Project description:CSB-depletion induced SH-SY5Y differentiation defects can be partially rescued by re-expression of SYT9 gene. This study characterizes the transcriptome signatures upon SYT9 re-expression in CSB-KD SH-SY5Y cells after RA treatment. The Nimblegen human 12 x 135K gene expression array was used to characterize the transcriptome landscape of CSB-KD SH-SY5Y cells overepressing SYT9 before and after RA treatment.

Project description:Neuroblastoma cells SH-SY5Y undergoes a morphology change upon retinoic acid (RA) treatment, the neurite outgrowth characteristic in undividing cells is accompanied by cell cycle arrest and neuronal markers expression, controlled by a precise dynamic molecular circuits. Depletion of CSB in SH-SY5Y cells leads to differentiation defects. This study examines the temporal gene expression profile during differentiation. Using Nimblegen microarray we characterized the gene expression profiles before and after RA treatment in both wild type and CSB-KD SH-SY5Y cells, and we identified the difference in gene expression between wild type and CSB-KD cells underlying the differentiation defects induced by CSB depletion.

Project description:Gene expression profile during SH-SY5Y neuroblastoma differentiation
| PRJNA248790 | ENA
Project description:The human neuroblastoma cell lines SH-SY5Y and IMR-32 can be differentiated into neuron-like phenotypes through treatment with all-trans retinoic acid (ATRA). After differentiation, these cell lines are extensively utilized as in vitro models to study various aspects of neuronal cell biology. However, temporal and quantitative profiling of the proteome and phosphoproteome of SH-SY5Y and IMR-32 cells throughout ATRA-induced differentiation has been limited. Here, we performed relative quantification of the phosphoproteomes of SH-SY5Y and IMR-32 cells at multiple time points during ATRA-induced differentiation. The data presented serve as a valuable resource for investigating temporal protein and phosphoprotein abundance changes in SH-SY5Y and IMR-32 cells during ATRA-induced differentiation.

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

Project description:We report here the expression profile of microRNAs in human neuronal differentiation in the neuroblastoma cell line SH-SY5Y. Six microRNAs were significantly upregulated during differentiation induced by all-trans¬-retinoic acid and brain-derived neurotrophic factor. We demonstrated that ectopic expression of either miR-124a or miR-125b increases the percentage of differentiated SH-SY5Y cells with neurite outgrowth. Subsequently, we focused our functional analysis on miR-125b and demonstrated the important role of this miRNA in both spontaneous and induced differentiation of SH-SH5Y cells, based on neurite outgrowth and neuronal marker expression. In human neural progenitor ReNcell VM cells, miR-125b is also upregulated during differentiation and miR-125b ectopic expression significantly promotes neurite outgrowth. To identify the targets of miR-125b regulation, we profiled the global changes in gene expression following miR-125b ectopic expression in SH-SY5Y cells. miR-125b represses 164 genes that contain the seed match sequence of the microRNA and/or predicted to be direct targets of miR-125b by conventional methods. Pathway analysis suggests that a subset of miR-125b-repressed targets antagonize neuronal genes in several neurogenic pathways, thereby mediating the positive effect of miR-125b on neuronal differentiation. We have further validated the binding of miR-125b to the microRNA response elements of ten selected targets. Together, we report here for the first time the important role of miR-125b in human neuronal differentiation.

Experiment Overall Design: Human neuroblastomas, SK-N-SH (HTB-11) and SH-SY5Y-A cells (CRL-2266) were obtained from the American Type Culture Collection (ATCC). We also obtained SH-SY5Y-E cells (EC94030304) from the European Collection of Cell Cultures (ECACC). Tissue culture cells were maintained in D-MEM/F12 1:1 mixture supplemented with 15% FBS (Fetal Bovine Serum) and 1% NEAA (Non-essential amino acid) in a 5% CO2 humidified incubator at 37oC. The culture medium was changed twice a week. For the RA-inducible experiment, random culture cells from two clone subtypes of SH-SY5Y and SK-N-SH were seeded in laminin coated culture dishes (BioCoat Laminin Cellware; BD Biosciences, Billerica, MA, USA) for 1 day and then transferred to a medium containing 10 μM of RA in the presence or the absence of LY294002 (10μM) for five days. For BDNF-induced sequential differentiation of the SH-SY5Y-E strain, cells were washed with D-MEM/F12 twice after five days in the presence of RA and then incubated with 50 ng/ml of BDNF in D-MEM/F12 without serum for three days.

Project description:To reveal the molecular mechanism underling necrotic neuronal cell death caused by norephedrine, we examined alteration of gene expression profile during norephedrine exposure in human neuroblastoma SH-SY5Y cells. The alteration of gene expression during norephedrine exposure (3 mM, 0,2 and 6 hours) in differentiated SH-SY5Y cells was examined.
