Project description:We analyzed the genome wide binding sites for the potential XLMR genes PHF8 and ZNF711 in the neuroblastoma cell line SH-SY5Y using antibodies specific for PHF8 and ZNF711 and correlated this with binding pattern of H3K4me3. The total number of peaks detected for PHF8 based on 9.8 million sequence reads, 9.6 million sequence reads for ZNF711 and 9.1 million sequence reads for H3K4me3 after IgG normalization were 17075, 1875 and 19534, respectively. Annotation of the peaks to genes using the hg18 genome database revealed 10039 genes positive for H3K4me3, 7682 were bound by PHF8 and 1103 genes were bound by ZNF711 within +/-1000bp from TSS. As former genome wide analysis of H3K4me3 revealed is this histone mark preferentially associated with transcription start sites. The analysis revealed that 82% of H3K4me3 positive genes are also positive for PHF8. In general, PHF8 either co-localizes or partly overlaps with regions positive for H3K4me3 and covers the putative TSS of the target genes.

Project description:PHF8 is an H3K9me2 demethylase, interacts with H3K4me3 and RNA Polymerase II, is enriched at thousands of transcription start sites and can act as a transcriptional co-activator. In the following experiment we wanted to analyze the impact of PHF8-knockdown on transcript levels in HeLa cells. Three independent replicate knockdown experiments with PHF8-shA and control NT-sh were performed (6 samples in total). The two samples of each replicate experiment were hybridized in two color dye swap experiments (6 arrays in total).

Project description:The aim of the experiment is to identify genome wide binding sites for the transcription factor MYCN in MYCN non-amplified and MYCN amplified human neuroblastoma cell lines. Datasets are presented for the ChIP-seq analysis in the tetracycline inducible cell line SH-SY5Y-MYCN (SH-SY5Y/6TR(EU)/pTrex-Dest-30/MYCN), derivative of the parental cell line SH-SY5Y; for noninduced cells and for 24 and 48 hours of Tet induction. Analysis for patinet matched MYCN amplified cell lines SMS-KCN and SMS-KCNR is also included.

Project description:iCLIP experiments tomap the RNA binding sites of the RNA-binding protein Unkempt across the transcriptome in SH-SY5Y cells, HeLa cells with ectopic Unk expression and mouse E15 embryonic brain samples. Expression of Unk is normally largely restricted to the nervous system. We therefore mapped the binding sites in human SH-SY5Y and mouse E15 brain to detect its physiological binding sites (in SH-SY5Y, we also performed the RNAseq experiment upon Unk knockdown). HeLa cells on the other hand normally don't express Unk, but convert to neuron-like shape when the protein is ectopically expressed. So, here we hoped to identify those binding events (and hence target transcripts) that are critical for this morphological transformation.

Project description:We analyzed the chromatin occupancies of active (H3K27ac and H3K4me3) and repressive (H3K27me3) histone marks in adrenergic (SH-SY5Y parental) and mesenchymal (SH-SY5Y LDK-resistant and SH-EP) neuroblastoma cells.

Project description:Mutations in PHF8 are associated with X-linked mental retardationand cleft lip/cleft palate. PHF8 contains a plant homeodomain(PHD) in its N-terminus and is member of a family of JmjC-domaincontaining proteins. While PHDs can act as methyl lysine recognitionmotifs, JmjC-domains can catalyze lysine demethylation. Here,we show that PHF8 is a histone demethylase that removes repressivehistone H3 dimethyl lysine 9 marks. Our biochemical analysisrevealed specific association of the PHF8 PHD domain with histoneH3 trimethylated at lysine 4 (H3K4me3). Chromatin-immunoprecipitationfollowed by high throughput sequencing indicated that PHF8 isenriched at transcription start sites of many active or poisedgenes, mirroring the presence of RNA polymerase II (RNAPII)and of H3K4me3-bearing nucleosomes. We show that PHF8 can actas a transcriptional co-activator and its activation functionlargely depends on binding of the PHD to H3K4me3. Furthermore,we present evidence for direct interaction of PHF8 with theC-terminal domain of RNAPII. Importantly, a PHF8 disease mutantis defective in demethylation and in co-activation. This isthe first demonstration of a chromatin-modifying enzyme whichis globally recruited to promoters through its association withH3K4me3 and RNAPII.

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 transcriptional regulation by ERRα and ERRγ in human neuronal cells, we investigated chromatin binding regions of ERRαlpha and ERRγ genome-wide in the SH-SY5Y cells. We detected thier target genes, which were largely overlap.

Project description:PHF8 is a histone demethylase associated with X-linked mental retardation (XLMR). It has been described as a transcriptional coactivator involved in cell cycle progression, but its physiological role is still poorly understood. Here we show that PHF8 controls the expression of genes involved in cell adhesion and cytoskeleton organization such as RhoA, Rac1 and GSK3M-NM-2. A lack of PHF8 not only results in a cell cycle delay but also in a disorganized actin cytoskeleton and impaired cell adhesion. Our data demonstrate that PHF8 directly regulates the expression of these genes by demethylating H4K20me1 at promoters. Moreover, c-Myc transcription factor interacts with PHF8 and binds to the analyzed promoters, suggesting that c-Myc is involved on PHF8 recruitment to these promoters. Further analysis in the neuroblastoma cell line SH-SY5Y and in cortical neurons shows that depletion of PHF8 results in deficient neurite elongation. Overall, our results suggest that the mental retardation phenotype associated with loss of function of PHF8 could be due to abnormal neuronal connections as a result of alterations in cytoskeleton function. HeLa cells were transfected with either control or PHF8 siRNAs. Experiments were performed in biological triplicates. RNA were extracted and sujected to microarray analysis.

Project description:PHF8 is an H3K9me2 demethylase, interacts with H3K4me3 and RNA Polymerase II, is enriched at thousands of transcription start sites and can act as a transcriptional co-activator. ChIP-seq of PHF8 in HeLa, 293T and Hs68 cells, and of H3K4me3 in Hs68 fibroblasts was performed. Normal IgG-IP or input DNA served as negative controls.
