Project description:Expression data from knockdown of ZXDC1/2 in PMA-treated U937
| PRJNA193671 | ENA
Project description:ZXDC1 augments the expression of various markers of monocyte/macrophage differentiation when over-expressed in the U937 cell line treated with the phorbol ester PMA. Likewise, knockdown of ZXDC1 restricts the induced expression of these markers. We sought to identify specfic gene targets of ZXDC1 during the process of monocyte/macrophage differentiation in U937 by performing gene expression profiling in cells exhibiting reduced expression of ZXDC1 compared to controls. We used microarray to identify genes regulated by ZXDC during PMA-induced differentiation of U937 monoblasts towards a monocyte/macrophage phenotype An inducible shRNAmir (Tet-On) cell line was established in the U937 background that displayed significant, reproducible, and doxycycline inducible knockdown of ZXDC1. Using this cell line, we created four experimental groups to identify gene targets of ZXDC1 during PMA-induced differention towards a monocyte/macrophage phenotype: Vehicle alone; Vehicle+Doxycycline; PMA alone; PMA+Doxycycline. Each independent group was used for RNA extraction and hybridization on Affymetrix microarray chips.

Project description:Human histomonocytic U937 cells exhibit macrophage-like properties after phorbol ester stimulation. Accumulating evidence demonstrated that remarkable number of transcripts changed in their amount at total RNA levels. However, post-transcriptional regulation has not been fully elucidated in this model. Thus, we compared expression profiles between polysomal and cytoplasmic RNAs before and after phorbol 12-myristate 13-acetate stimulation (48h, 32nM).

Project description:Gene expression: Identification of primary target genes of liver X receptor (LXR) in an immune-related cellular model (THP-1 cells) to study, in conjunction with LXR binding data from ChIP-seq, the genome-wide mechanisms of transcriptional regulation by LXR. ChIP-Seq: We performed ChIP-seq in macrophage-type PMA-differentiated THP-1 cells after stimulation with the potent synthetic LXR ligand T0901317 (T09). As a reference we performed microarray gene expression analysis in the same cellular model. We identified in total 1357 LXR binding locations on chromatin (FDR < 1%), of which 526 were observed after T09 treatment. De novo analysis of LXR site sequences identified DR4-type binding sites as major motif. gene expression: THP-1 cells were treated for 4 h with 1 M-BM-5M T09 or vehicle (DMSO) ChIP-Seq: PMA-differentiated THP-1 cells were treated for 60 min with 1 M-BM-5M T09 or vehicle (DMSO)

Project description:FVB/N mice were subjected to 7,12-Dimethylbenz[a]anthracene (DMBA) two-hit multistage skin carcinogenesis protocol. Mice were topically treated with 200 nmol of DMBA in 0.2 mL acetone then twice weekly for six weeks with 5 nmol PMA (Phorbol 12-myristate 13-acetate). A second hit of DMBA was performed on the eighth week followed by the resumption of PMA treatment for 14 more weeks. Control mice were only topically treated with 0.2 mL acetone vehicle. Healthy skins (acetone-treated), hyperplastic skins, papillomas and tumors were harvested throughout the protocol and biopsies were frozen for RNA extraction.

Project description:Early growth response gene 1 (EGR1) has been implicated in megakaryocyte differentiation induced by PMA (phorbol 12-myristate 13-acetate). The identification of direct EGR1 target genes in global scale is critical for our understanding of how EGR1 contributes to this process. In this study, we provide a global survey on the binding location of EGR1 in the K562 cell treated by PMA using chromatin immunoprecipitation and massively parallel sequencing (ChIP-Seq). K562 is a human erythroleukemia cell line, which is situated in the common progenitor stage of megakaryocytic and erythroid lineages of the hematopoietic stem cell differentiation and its normally following differentiation is blockaded. Upon exposure to PMA stimuli, K562 cell can be induced into megakaryocytic cell, which provides a model for the study of transcriptional control networks. Over 14 000 highly confident in vivo EGR1 binding sites were identified in PMA treated K562 cell. More than 70% of these genomic sites associated with EGR1 binding were located around annotated gene regions. This whole genome study on the EGR1 targets may help a better understanding of the EGR1 regulated genes and the downstream pathway in megakaryocyte differentiation. The in vivo binding locations of EGR1 in K562 cell treated with PMA (phorbol 12-myristate 13-acetate, 10 ng/ml for 2 hours) were identified using chromatin immunoprecipitation combing with massively parallel sequencing (ChIP-Seq) based on AB SOLiD System 2.0.

Project description:Pan-viral DNA array (PVDA) and high-throughput sequencing (HTS) are useful tools to identify novel virus of emerging diseases. However, both techniques have difficulties to identify viruses in clinical samples because of host genomic DNA (hgDNA) contamination. Both propidium monoazide (PMA) and ethidium bromide monoazide (EMA) have the capacity to bind free DNA but are cell membrane-impermeable and thus are unable to bind protected DNA and RNA such as viral genomic material. DNA modified by EMA or PMA is not amplifiable by polymerase. In order to assess the capacity of EMA or PMA to lower hgDNA, serum or lung tissue homogenates were spiked with porcine reproductive and respiratory virus (PRRSV) and were processed with different combination of treatment: with or without ultracentrifugation and incubation with or without different concentration of EMA or PMA. PVDA and HTS were used to evaluate the capacity of both techniques to detect the presence of PRRSV from each sample. Negative results were obtained by PVDA and low amount of PRRSV specific reads were obtained by HTS with untreated samples or samples treated only by ultracentrifugation. An increase capacity of PRRSV detection was observable by PVDA in EMA and PMA treated samples but PVDA best results were obtained following PMA treatment, with or without ultracentrifugation. HTS sensitivity was also improved by a treatment with EMA or PMA, but the number of reads was significantly higher in PMA treated samples. These results support the use of PMA as a treatment to increase sensitivity of PVDA and HTS.
