Microarray Gene Expression Analysis of control and UBF knockdown in NIH3T3 cells

ABSTRACT: UBF is an essential RNA Polymerase I (Pol I)-transcription factor. Our research investigates extra roles for UBF in regulation of Pol II gene expression. Our gene expression data identifies genes that are differentially regulated following UBF knockdown by siRNA. RNA was extracted from NIH3T3 cells after 48 hour of transfection with two independent siRNA oligonucleotides targeting UBF, sirEGFP or Mock control. A total of 12 samples were analysed using Affymetrix arrays.We include the expression data from three biological replicate experiments

Expression data of NIH3T3 in G0 and G1 phases

Project description:NIH3T3 in the middle of G0 to G1 transion consists of the cells which is still staying G0 phase and the cells which enters G1. Monitoring the expressions of p27 and Cdt1 enables to distinguish these two; p27+/Cdt1+ cells as the cells in G0 phase and p27-Cdt1+ cells as G1 phase We sorted p27+Cdt1+ (G0) NIH3T3 cells and p27-Cdt1+ (G1) NIH3T3 cells in the middle of G0-G1 transition, 5 hours after serum addition following the serum addition using mVenus-p27K- and mCherry-hCdt1(30/120) . We compared the expression profiles of these NIH3T3 cells in G0 and G1 phases and identified the genes upregulated in G0 or G1 phases. The p27+Cdt1+ (G0) NIH3T3 cells and p27-Cdt1+ (G1) NIH3T3 cells were sorted by FACS for RNA extraction and hybridization on Affymetrix microarrays.

Nutrient-dependent growth of NIH3T3 and NIH3T3 K-ras cell lines.

Project description:Expression profiling of normal NIH3T3 and transformed NIH3T3 K-ras cell lines grown for 72 hours in optimal glucose availability (25 mM glucose) or low glucose availability (1 mM). Low glucose induces apoptosis in transformed cells as compared to normal ones. We performed genome-wide analysis by using Affymetrix GeneChip oligonucleotide microarrays to identify those genes whose expression levels are modulated by glucose availability in NIH3T3 and NIH3T3 K-ras cell lines. The cells, to be used for the transcription analysis, were collected at 18h from the initial seeding, time corresponding to the change of medium (25 or 1 mM glucose, indicated as T0) and then at 24, 48 and 72h upon medium change.

Illumina mRNA-Seq of control and hnRNP H knockdown in 293T cells

Project description:Pre-mRNA splicing is regulated through combinatorial activity of RNA motifs including splice sites and splicing regulatory elements (SREs). Here, we show that the activity of a major class of mammalian SREs is highly sensitive to the strength of the adjacent 5' splice site (5'ss) sequence, and that this has important functional and evolutionary implications. Activity of G-run SREs was higher for intermediate strength 5'ss by ~4-fold relative to weak 5'ss, and by ~1.3-fold relative to strong 5'ss. The dependence on 5'ss strength was supported both by comparative genomics and by microarray and Illumina mRNA-Seq analyses of splicing changes following RNAi against the splicing factor heterogeneous nuclear ribonucleoprotein (hnRNP) H, which binds G-runs. This dependence implies that the responsiveness of exons to changes in hnRNP H levels is a bivariate function of both SRE abundance and 5'ss strength; this relationship may hold also for other splicing factors. This pattern of activity enables G-runs and hnRNP H to buffer the effects of 5'ss mutations, augmenting both the frequency of 5'ss polymorphism and the evolution of new splicing patterns. Examine mRNA expression in 293T cells following hnRNP H or control siRNA knockdown

Circadian rhythm in NIH3T3 cells

Project description:Identification of cyclical expressed coding and non-coding genes during the circadian rhythm in NIH3T3 cells. NIH3T3 cells were synchronized for their circadian rhythm and RNA sequencing were performed at several time points along the rhythm. This data was used to identify cyclical expressed genes as well as long intergenic non-coding RNAs. NIH3T3 cells were synchronized with 100 nM Dexamethasone for 2 hours, then medium was changed to normal culture medium (0h). Every 4 hours cells were harvested, RNA isolated and RNAseq performed.

Proteomic analysis identifies the potential effects of trichostatin A and bone marrow-derived dendritic cells on NIH3T3 cells under oxygen–glucose deprivation conditions

Project description:Fibroblasts usually mediate acute wound healing and long-term tissue remodeling with scarring in tissue injury. In myocardial infarction (MI), following a prolonged lack of oxygen supply, necrotized cardiomyocytes become replaced by secreted extracellular matrix proteins produced by fibroblasts. Dendritic cells (DCs) act as inflammatory cells and can migrate from the bone marrow to the infarct areas and infarct border areas to mediate collagen accumulation after MI, whereas trichostatin A (TSA) can regulate the apoptosis and proliferation of the fibroblasts and affect DCs functions under oxygen–glucose deprivation (OGD) conditions. In this study, we used proteomics to investigate the effects of TSA and bone marrow-derived dendritic cells (BMDCs) on NIH3T3 fibroblasts under OGD conditions. Results showed that the fatty acid degradation pathway was significantly upregulated in NIH3T3 cells under OGD conditions, and the fatty acid synthesis pathway was significantly downregulated in NIH3T3 cells treated with BMDCs conditioned media with TSA (BMDCs-CM[TSA]) under OGD conditions. Meanwhile, the BMDCs-CM(TSA) significantly decreased the levels of triglycerides and free fatty acids and mediated ten fatty acid metabolism-related proteins in the NIH3T3 cells under OGD conditions. Summarily, the proteomic analysis showed that TSA and BMDCs affect fatty acid metabolism in NIH3T3 cells under OGD conditions.

Gene expression profiles of NIH3T3 influenced by MARVELD1

Project description:To investigate biological function of MARVELD1, we have employed whole genome microarray expression profiling as a platform to analyze gene expression alternation influenced by MARVELD1. MARVELD1 stably transfected NIH3T3 and control vector cells were used to compare their gene expression profiling. Total RNA from MARVELD1 overexpressing NIH3T3 cells and control cells were extracted to analyze their gene expression profiles by using mouse whole genome expression microarray.

Project description:We report ChIP-Seq analysis of the RNA polyemerase I trascription factor UBF1/2 in NIH3T3, HMEC and HMLER cell lines. NIH3T3* samples: We correlated UBF1/2 binding across the genome with that of RNA polemerase I (Pol I), RNA polemerase II (Pol II) and chromatin states in NIH3T3 cells We perfromed ChIP-seq of UBF1/2 (2 biological replicates), Pol I (POLR1A/RPA194), Pol II, H3K9me3, H3K4Me3, H3K9ac, H4 hyperacetylation and genomic DNA input as reference. HMEC* samples: We report ChIP-Seq analysis of UBF1/2 and Pol I (POLR1A/RPA194) in human mammary epithelial cells (HMEC). In addition we include UBF1/2 ChIP-seq in the tumourigenic epithelial cell line HMLER. In this study, we compared UBF1/2 binding in HMEC to UBF1/2 binding in in the tumorigenic HMLER cells, an isogenic HMEC-derived cell line expressing the SV40 large-T, TERT, and an oncogenic allele of the HRAS gene (expressing HRASV12G) that forms tumors in nude mice (Elenbaas et al., Gene & Development 2001) We sequenced UBF1/2 ChIP and Pol I(POLR1A/RPA194) ChIP and gDNA input from HMEC. We sequenced UBF1/2 ChIP and gDNA input from HMLER
