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 proteomes 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:SH-SY5Y neuroblastoma cells are widely used as in vitro neuronal model. They can be induced to a differentiated phenotype, presenting neurites and synaptical-like structures in response to retinoic (RA) acid and brain-derived neurotrophic factor (BDNF), providing a model to analyze neuronal differentiation. We report a large scale MS quantification of SH-SY5Y cells proteome during its differentiation process after treatment with RA/BDNF. Using isobaric tags for relative and absolute quantification (iTRAQ) approach and phosphopeptide enrichment protocols, we identified a total of 5587 proteins, 366 of them showed differential abundance between both conditions of culture. Differentiated SH-SY5Y cells showed regulation of proteins and phosphosites strongly related to neuronal development, in contrast, undifferentiated cells expressed proteins more related to cell proliferation and control of cell cycle. Interactive network analysis covered processes as focal adhesion, cytoskeleton dynamics and neurodegenerative diseases and pathway analysis displayed regulation of mitogen-activated protein kinase and phosphoinositide 3-kinase/Akt signaling pathways mainly; the proteins involved in those processes might be considered as markers for neuronal differentiation. Overall the data collection presented here can be explored for any studies which intent to use SH-SY5Y as neuronal model.

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. 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:The proteomes of undifferentiated and differentiated SH-SY5Y cells are characterised and compared. For this, neuronal differentiation using retinoic acid (RA) or a combination of RA and phorbol-12-myristat-13-acetate (RA/PMA) was explored. An MS-based label-free quantification approach is applied to identify changes in the protein expression, the as proteins’ subcellular localisation abundance as well as their association with enriched KEGG pathways. By employing formaldehyde cross-linking insights into protein interaction networks of undifferentiated as well as RA- and RA/PMA-differentiated neurons are obtained. The analyses provided insights into the proteomes of undifferentiated and differentiated SH-SY5Y cells and suggest structural rearrangements, for instance, of the actin network during neuronal differentiation.

Project description:Zika virus (ZIKV) is an emerging, mosquito-borne pathogen associated with a widespread 2015–2016 epidemic in the Western Hemisphere and a proven cause of microcephaly and other fetal brain defects in infants born to infected mothers. ZIKV infections have been also linked to other neurological illnesses in infected adults and children, including Guillain-Barré syndrome (GBS), acute flaccid paralysis (AFP) and meningoencephalitis, but the viral pathophysiology behind those conditions remains poorly understood. Here we investigated ZIKV infectivity in neuroblastoma SH-SY5Y cells, both undifferentiated and following differentiation with retinoic acid. We perform RNA seq, and global trancriptome analysis to corroborate the effect of retinoic acid in SH-SY5Y cells. Then we analyze the virus infection in differentiated and undifferntiated cells. We found that multiple ZIKV strains, representing both the prototype African and contemporary Asian epidemic lineages, were able to replicate in SH-SY5Y cells. Differentiation with resultant expression of mature neuron markers increased infectivity in these cells, and the extent of infectivity correlated with degree of differentiation. Enhanced ZIKV infectivity in a neural cell line following differentiation may contribute to viral neuropathogenesis in the developing or mature central nervous system.

Project description:Human SH-SY5Y neuroblastoma cells are widely utilized in in vitro studies to dissect out pathogenetic mechanisms of neurodegenerative disorders. These cells are considered as neuronal precursors and differentiate into more mature neuronal phenotypes under selected growth conditions. In this study, we performed systematic transcriptomic (RNA-seq) and bioinformatic analysis to pinpoint pathways and cellular processes underlying neuronal differentiation of SH-SY5Y cells according to a two-step paradigm: retinoic acid treatment followed by enriched neurobasal medium. Categorization of 1989 differentially expressed genes (DEGs) identified in differentiated cells outlined meaningful biological functions associated with changes in cell morphology including remodelling of plasma membrane and cytoskeleton, neuritogenesis. Seventy-three DEGs were assigned to Axonal Guidance Signalling pathway, and the expression of selected gene products such as neurotrophin receptors, the functionally related SLITRK6, and semaphorins, was validated by immunoblotting. Along with these findings, the differentiated cells exhibited the ability to elongate longer axonal process as assessed by the morphometric evaluation. Recognition of molecular events occurring in differentiated SH-SY5Y cells is necessary to accurately interpret the cellular responses to specific stimuli in studies on disease pathogenesis.

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.
