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:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
