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: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

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 SH-SY5Y Human neuroblastoma cell line was subcloned from the SK-N-SH cell line, which has been isolated from a bone marrow biopsy of a 4 year-old female patient. To examine the overall distribution of gene expression under stress condition in human neuronal cells, we investigated changes in the transcriptome profiles in the SH-SY5Y cells exposed with sodium arsenite which causes oxidative stress. We detected changes in the expression levels for several genes including FOS and Jun, which are well-known stress-dependent upregulated genes.

Project description:During brain development, histone-modifying enzymes play an important role by orchestrating transcriptional programs that regulate neuronal maturation. Lysine-Specific Demethylase 1 (LSD1, also named as KDM1A) functions as a transcriptional repressor by removing methyl groups at lysine 4 of histone H3 (H3K4). In neurons, alternative splicing can include an additional exon (exon E8a) within LSD1 transcripts, generating a LSD1+8a neuro-specific isoform. We here report that LSD1+8a isoform does not have the intrinsic ability to demethylate H3K4. LSD1+8a functions as a co-activator on its target genes by removing H3K9 repressive histone marks. We identify the supervillin protein (SVIL) as a LSD1+8a interacting partner and demonstrate that SVIL protein regulates neuronal maturation by controlling LSD1+8a mediated H3K9 demethylation. Thus, our results show that alternative splicing provides a genius mechanism by which LSD1 isoforms can acquire a dual specificity (H3K9 vs H3K4) and therefore differentially control specific gene expression patterns during brain development. In order to find some LSD1+8a regulated genes at differentiated SH-SY5Y cell lines, we infected SH-SY5Y with control or LSD1+8a shRNA, then induced differentiation with RA and BDNF, (Retinoic acid (RA) (Sigma) was added at a final concentration of 10 μM the next day after plating. After 4 days, the cells were washed three times with PBS and incubated with 50 ng/mL of Brain Derived Neural Factor (BDNF) (Millipore) in serum-free medium for 3 days), we extracted RNA from BDNF induced SH-SY5Y cells for expression analysis.Duplicates were included for Affymetrix Human transcriptome version 2 array.
