Transcription profiling by array of human HEK293 cells overexpressing SOX11

ABSTRACT: We have carried out a cell line-based overexpression study coupled with microarray analysis to characterise the set of genes regulated by SOX11 and therefore critical for neurodevelopmental processes important in health and disease. The HEK293 cells were transiently transfected by pDEST40-SOX11 or control plasmid (pDEST40).Cells were collected at 24 hours post-transfection.Total RNA from alll samples was extracted.Biotinylated cRNA was prepared using the Illumina total Prep RNA application Kits.Hybridization, washing and scanning were performed according to the Illumina BeadStation 500* manual (revision C)

NPAS3-HEK293-circadian-Illumina

Project description:The fragments of FLNPAS3 and DeltaNPAS3 were transferred into a similar TET-inducible expression plasmid and transfected into HEK293 [T-REx-293] cells (Invitrogen). At the zero hour time-point, cells were shifted into a serum-rich medium plus tetracycline in order to induce circadian cycling and NPAS3 overexpression. Parental HEK293 [T-REx-293] cells after circadian rhythmcity induction for +12hr/+24hrs were used as negative controls because stably integrated FLNPAS3/DeltaNPAS3 cell lines showed a low level of leaky transcription in the absence of tetracycline. At +2 hours, cells were washed with DMEM and then incubated with the same plus tetracycline for the remaining period of the experiment. Cell samples were collected at +12hrs and +24hrs respectively. For all circadian cell culture experiments with FLNPAS3/DeltaNPAS3/parental negative control cell lines, duplicate biological samples were assessed. Microarray probes synthesised from RNA extraction products was quantified using an Agilent Bioanalyzer to ensure high quality probes of equal quantity between experiments. Sentrix® HumanRef-8 v2 chips were used to detect gene expression profiles.

Mastermind-like protein 1 regulates DNA methylation and expression of early developmental gene clusters in human embryonic kidney cells (methylation)

Project description:Mastermind-like 1 (MAML1) is a transcriptional coregulator that has been associated with early development of many systems such as neuronal, muscular, cardiovascular and urogenital. The present study aimed to explore the genome-wide effects of MAML1 on gene expression and DNA methylation in human embryonic kidney cells. RNA expression was measured using a microarray that screens approximately 36,000 transcripts, and DNA methylation was determined for 450,000 CpG sites. 225 genes were found to be differentially expressed, while 11802 CpG sites were found to be differentially methylated in MAML1-expressing cells. A subset of 211 differentially methylated loci was associated with the expression of 85 genes. Gene ontology analysis revealed that these genes are involved in the regulation of urogenital system development, cell adhesion and embryogenesis. The aim of the study was to identify genes regulated by mastermind-like pritein 1 and DNA methylation, using genome-wide approach. We assayed the effects of MAML1 overexpression, as well as knock-down, on global DNA methylation profiles in HEK293 cells. 11802 CpG sites were found to be differentially methylated in MAML1-overexpressing cells. However, no significant changes were observed by comparing HEK293_H_siControl with HEK293_H_siMAML1.

Chromatin immunoprecipitation of human HEK cells immunoprecipitated by Staufen1

Project description:In human cells, Staufen1 is double-stranded RNA-binding protein involved in several cellular functions including mRNA localization, translation and decay. We used a genome wide approach to identify and compare the mRNA targets of mammalian Staufen1. The mRNA content of Staufen1 mRNPs was identified by probing DNA microarrays with probes derived from mRNAs isolated from immunopurified Staufen-containing complexes following transfection of HEK293T cells with a Stau1-HA expressor. Our results indicate that 7% of the cellular RNAs expressed in HEK293T cells are found in Stau1-containing mRNPs. There is a predominance of mRNAs involved in cell metabolism, transport, transcription, regulation of cell processes and catalytic activity. Experiment Overall Design: HEK293 cells were transiantly transfected with plasmids coding for Staufen1-HA. Cell extracts were immunoprecipitated using anti-HA antibodies and co-immunoprecipitated mRNAs were purified and used to hybridize microarrays. As control, cell extract from mock transfected cells were used.

Chromatin immunoprecipitation profiling of human HEK293 cells transiantly transfected with plasmids coding for Staufen2-HA isoforms

Project description:In human cells, Staufen2 is a double-stranded RNA-binding protein involved in several cellular functions. Although 51% identical to Staufen1, these proteins are nevertheless found in different RNA particles. In addition, differential splicing events generate Staufen2 isoforms that only differ at their N-terminal extremities. We used a genome wide approach to identify and compare the mRNA targets of mammalian Staufen2 isoforms. The mRNA content of Staufen mRNPs was identified by probing DNA microarrays with probes derived from mRNAs isolated from immunopurified Staufen2-containing complexes following transfection of HEK293T cells with Stau2-HA (59kDa) or Stau2-HA (62kDa) expressors. Our results indicate that 11% of the cellular RNAs expressed in HEK293T cells are found in Stau2-containing mRNPs. There is a predominance of mRNAs involved in cell metabolism, transport, transcription, regulation of cell processes and catalytic activity. Experiment Overall Design: HEK293 cells were transiantly transfected with plasmids coding for Staufen2-HA isoforms. Cell extracts were immunoprecipitated using anti-HA antibodies and co-immunoprecipitated mRNAs were purified and used to hybridize microarrays. As control, cell extract from mock transfected cells were used.

We assayed the effects of MAML1 overexpression, as well as knock-down, on global gene expression profiles in HEK293 cells. We applied a filter of p < 0.01 for significantly modulated gene expression and at least a 1.5-fold change in mean differential expression. By comparing HEK293 (AW01-03_H average) with HEK293_MAML1 samples (AW04-06_MAML1 average), 225 genes were found to be differentially expressed. However, no significant changes were observed by comparing HEK293_H_siControl (AW13-14_H_siCtrl average) with HEK293_H_siMAML1 (AW15-16_siMAML1 average).

High resolution ChIP sequencing reveals novel bindings targets and prognostic role for SOX11 in Mantle cell lymphoma (RNA-Seq)

Project description:SOX11 (Sex determining region Y-box 11) expression is specific for MCL as compared to other Non-HodgkinM-bM-^@M-^Ys lymphomas. However, the function and direct binding targets of SOX11 in MCL are largely unknown. We used high-resolution ChIP-Seq to identify the direct target genes of SOX11 in a genome-wide, unbiased manner and elucidate its functional significance. Pathway analysis identified WNT, PKA and TGF-beta signaling pathways as significantly enriched by SOX11 target genes. qCHIP confirmed that SOX11 directly binds to individual genes in these pathways in both MCL cell lines and patients. Interrogation of an eighty-two patientM-BM- gene-expression dataset demonstrated that SOX11 mRNA expression was inversely proportional to Ki-67, a marker of cell proliferation. Functional studies using RNA interference demonstrate that SOX11 directly regulates WNT signaling and modulates chemotherapy sensitivity to cytarabine in MCL. We analyzed SOX11 expression in three independent well-annotated tissue microarrays from the University of Wisconsin (UW), Karolina Institute and British Columbia Cancer Agency (BCCA). Our findings suggest that high SOX11 expression is associated with improved survival in a subset of MCL patients, particularly those treated with intensive chemotherapy incorporating cytarabine. Transcriptional regulation of WNT and other biological pathways affects by SOX11 target genes may help explain the impact of SOX11 expression on patient outcomes. RNA-seq experiments studying SOX11-mediated regulation of gene transcription by examining genes differentially expressed following SOX11 depletion in 3 MCL cell lines, Granta-519, Z138 and JEKO-1
