SiRNA profiling of human SH-SY5Y cells after LSD1 knock down

ABSTRACT: To analyze the functional relevance of LSD1 in neuroblastic tumors, SH-SY5Y cells were transiently transfected with siRNA directed against LSD1 or with a scrambled control siRNA. Microarray analysis revealed changes in expression that were consistent with these observations 72 hours after LSD1 knock-down. At this time, 28 genes were significantly induced at least 1.5-fold and 29 genes were significantly repressed at least 1.5-fold. Among the 28 induced genes, 4 are markers of cytoskeletal remodelling (TNS1, TPM1, DNM2, DNAL4), indicating differentiation, and 3 (TPM1, DNM2 and SHANK2) are functionally linked to neurite dynamics and synaptic trafficking. TaqMan quantitative RT-PCR confirmed the expression changes detected via microarray analysis for LSD1, DNAL4, DNM2, TNS1 and TPM1 Experiment Overall Design: SH-SY5Y cells were transfected with siRNA directed against LSD1 or control siRNA. 2 independent transfection experiments were performed each. Reverse transcription, labelling of total RNA and subsequent hybridization to Affymetrix U133v2 chips were performed according to the manufacturerÂ´s protocols

Project description:To investigate impact of CLN3 deficiency on cell signaling and metabolism, SH-SY5Y neuroblastoma cells were transiently transfected with CLN3 siRNA (siCLN3; n=3) or control siRNA (siCTL; n=3). Transcriptomes of siCTL and siCLN3 SH-SY5Y cells were determined using Affymetrix Human Genome U133 plus 2 arrays.

The LSD1/KDM1A neuro-specific isoform regulates neuronal differentiation through H3K9 demethylation [Affymetrix]

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.

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.

LSD1 knockdown in 3T3-L1 preadipocytes

Project description:Obesity is often associated with a low-grade systemic inflammation state that contributes to the development of insulin resistance and atherosclerotic complications. This is usually coupled with increased macrophage infiltration in the adipose tissue and a defect in adipocyte differentiation that results in accumulation of hypertrophic fat cells characterized by a deregulated pattern of adipokine expression. Here we show that knockdown of histone demethylase lsd1 in 3T3-L1 preadipocytes results in defective adipogenesis and derepression of an inflammatory program in these cells. The dataset consists of four sample groups: [1] 3T3-L1 preadipocytes (passage 19) transfected with a control scrambled siRNA at 24h after transfection (siC.24h), [2] 3T3-L1 preadipocytes (p.19) transfected with a siRNA directed against LSD1 at 24h after transfection (siLsd1.24h), [3] 3T3-L1 preadipocytes (p.21) transfected with a control scrambled siRNA at 48h after transfection (siC.48h), and [4] 3T3-L1 preadipocytes (p.21) transfected with a siRNA directed against LSD1 at 48h after transfection (siLsd1.48h). The 24h sample groups (siC.24h and siLsd1.24h) consist of two biological replicate samples; the 48h sample groups (siC.48h and siLsd1.48h) consist of three biological replicate samples. Each sample was hybridized to a separate array, for a total of ten arrays.

Transcriptome of human neuroblastoma SH-SY5Y cells in response to 2B protein of enterovirus-A71

Project description:Non-structural 2B protein of enterovirus-A71 has reported involving in intracellular Ca2+ manipulation and altering cellular homeostasis such as inducing cell death in human SH-SY5Y cells. The aim of the study is to profile transcriptomic signature of human neuroblastoma SH-SY5Y cells altered by EV-A71 2B protein using RNA-sequencing analysis. We generated mRNA expression profiles of SH-SY5Y cells transfected with EV-A71 2B protein fused with mCherry and FLAG tag protein (2BmCherry) and mCherry as well as parental SH-SY5Y cells. We find that 7 genes including CCL2, RELB, IL32, PLAT, PTGES, PHLDA1, and TNFRSF9 are uniquely overexpressed in 2BmCherry comparing to mCherry. Moreover, there were 333 upregulated and 333 downregulated genes showed significant different expression level in 2BmCherry transcriptome in comparison with SHSY5Y transcriptome but not in mCherry vs SHSY5Y comparison. Functional analysis showed that EV-A71 2B upregulated genes involved Ca2+-related signaling pathways participating gene expression, immune response, apoptosis, and long-term potentiation (synaptic adaptation) of neuron in the transfected SH-SY5Y cells.
