Project description:Expression profiling of NB4 cells after treatment with ATRA
| PRJNA118087 | ENA
Project description:NB4 is an APL derived cell line, carrying the t(15;17) translocation and expressing the PML/RARa fusion protein. Still, an important question that remains to be addressed is whether PML/RARa target genes are transcriptionally suppressed in primary APL cells and re-activated in all-trans retinoic acid (ATRA) treated NB4 cells. Gene expression of NB4 cells treated with ATRA at different time points were analyzed.

Project description:ATRA was identified as a Pin1 inhibitor via fluorescence polarization-based high throughput screening. We performed microarray expression profiling to demonstrate the similarity between ATRA and Pin1 KD at the genome-wide level APL NB4 cells in response to ATRRA or inducible Pin1 knockdown for 3 days were collected for RNA extraction and hybridization on Affymetrix microarrays. We sought to validate in genome-wide level whether similarity occurred between ATRA and Pin1 knockdown-treated NB4 cells.

Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.

Project description:Illumina High-Throughput ChIP Sequencing profiling was performed using the H3K9K14ac antibody in NB4 cells treated with the compounds ATRA, MS-275,MC2392 (a hybrid molecule of ATRA with a 2-aminoanilide tail of the HDAC inhibitor MS-275) or solvent, DMSO. We find that MC2392 induces changes in H3 acetylation at a small subset of PML-RARα binding sites but also in regions not regulated by ATRA. Moreover, MC2392 alters expression of a number of stress-responsive and apoptotic genes.

Project description:Treatment of acute promyelocytic leukemia (APL) with all-trans-retinoic acid (ATRA) results in terminal differentiation of leukemic cells toward neutrophil granulocytes. Administration of ATRA leads to massive changes in gene expression, including down-regulation of cell proliferation-related genes and induction of genes involved in immune function. One of the most induced genes in APL NB4 cells is transglutaminase 2 (TG2). RNAi-mediated stable silencing of TG2 in NB4 cells (TG2-KD NB4) coupled with whole genome microarray analysis revealed that TG2 is involved in the expression of a large number of ATRA-regulated genes. The affected genes participate in granulocyte functions and their silencing lead to reduced adhesive, migratory and phagocytic capacity of neutrophils and less superoxide production. The expression of genes related to cell cycle control also changed, suggesting that TG2 regulates myeloid cell differentiation. CC chemokines CCL2, 3, 22, 24 and cytokines IL1B and IL8 involved in the development of differentiation syndrome (DS) are expressed at significantly lower levels in TG2-KD NB4 cells than in wild-type NB4 cells upon ATRA treatment. Based on our results, we propose that reduced expression of TG2 in differentiating APL cells may suppress effector functions of neutrophil granulocytes and attenuate the ATRA-induced inflammatory phenotype of DS. We used microarrays to detail the global program of gene expression underlying ATRA-induced differentiation of TG2 knockout NB4 cells. TG2 knockout NB4 cells were differentiated for 48 and 72 hours in the presence of ATRA and their gene expression profiles were compared to the wild-type cells at the same time points. Undifferentiated wild-type and TG2 knockout NB4 cells were used as untreated controls. Three biological replicates each.
