Project description:Transcriptional profiling of human leukemia HL-60 cells comparing ATRA treated HL-60 cells with ATRA plus ATO. Goal was to determine the effects of ATO on ATRA induced differentiation of HL-60 cells.
Project description:These RNA-seq data were generated to correlate with genomic interaction data in a related Hi-C analysis. Analysis revealed differential expressed genes in ATRA treated and control HL-60 cells. Changes of gene expression with topological associated domains (TADs) were showd to be correlated with chromatin structure alteration
Project description:We performed RNA-Seq on acute promyelocytic leukemia (APL) cells treated with both all-trans retinoic acid (ATRA) and trichostatin A (TSA) to identify transcriptional changes potentially associated with changes in APL cell mechanical properties. As a control, we performed the same treatments and RNA-Seq analysis on HL-60 cells, which were derived from a patient diagnosed with APL but whose cells lacked the hallmark fusion gene associated with APL. We performed RNA-Seq on these three cell lines (AP-1060, NB4, HL-60) under different conditions (untreated, TSA, ATRA, TSA + ATRA), and identified differentially expressed genes between samples and conditions. This study identified differentially expressed genes and enriched gene sets associated with (1) a resistance to differentiation induced by ATRA or (2) changes in mechanical properties. Overall, we find evidence that ATRA resistance and mechanical properties may be linked by the degree of chromatin condensation in APL cells.
Project description:Transcriptional profiling of human leukemia?HL-60 cells comparing ATRA treated HL-60 cells with ATRA plus ATO. Goal was to determine the effects of ATO on ATRA induced differentiation of HL-60 cells. Two-condition experiment, ATRA vs. ATRA plus ATO treated HL-60 cells.
Project description:These ChIP-seq data were generated to correlate with genomic interaction data in a related Hi-C analysis.The goal of ChIP-seq are to annotate active promoter and enhancer of ATRA treated and control HL-60 cells. After ATRA induction, H3K27ac peaks distal to gene promoters showed significant changes. Those changes were correlated with interaction intensity between promoters and enhancers.
Project description:All-trans retinoic acid (ATRA)-based differentiation therapy has achieved success with the treatment of acute promyelocytic leukemia (APL), a unique subtype of acute myeloid leukemia (AML). However, other subtypes of AML display resistance to ATRA-based treatment. Here, we demonstrate that a novel natural vibsane-type diterpenoid vibsanine A promotes the differentiation of myeloid leukemia cell lines and primary AML blasts. To reveal how vibsanine A function on promoting myeloid leukemia cell differentiation, we analyzed and compared the gene expression profiles in myeloid leukemia HL-60 cells treated with vibsanine A, PMA, and ATRA. HL-60 cells were treated with vibsanine A, PMA and ATRA for 6 hours or longer up to 24 hours. Gene expression profiling was conducted
Project description:We investigate the effects of GCN5 and LSD1 inhibition in acute myeloid leukemia. Therefore, we characterized gene expression changes by RNA-seq in AML cells (AML M2 cell line HL-60) following treatment with ATRA, MB3, GSK-LSD1 and their combinations.
Project description:ATRA-induced differentiation of HL-60 cells was studied using targeted mass-spectrometry including selected reaction monitoring (SRM) and parallel reaction monitoring (PRM) approach. PRM experiment was performed in time-course manner, without peptide standards usage. PRM data was inspected in Skyline 3.1 software. In order to check peptide identity we developed spectrum library based on shotgun mass-spectrometry data, which has been obtained for HL-60 cells protein samples at 0, 3, 24, 48 and 96h after ATRA treatment.
Project description:The leukemic cell line HL-60 is widely used to study normal and aberrant myelopoiesis. HL-60 cells can be treated with ATRA (all-trans retinoic acid) and Vit-D3 (1,25-Dihydroxyvitamin D3, calcitriol) to differentiate into granulocytes and monocytes respectively. Induced myeloid differentiation helps us to understand the molecular basis of myeloid differentiation. To understand the genome-wide gene expression changes associated with HL-60 cells upon myeloid differentiation, RNA-sequencing was carried out. We subjected the HL-60 cells with 10 µM ATRA and 50 nM Vit-D3 for 72 hours. Post induction, the uninduced and induced cells were sorted based on CD11b and CD14 markers. The uninduced cells were negative for both the markers while ATRA and Vit D3 inductions were highly positive for CD11b-FITC and CD14-APC-H7 markers respectively. Two biological replicates were used for this experiment. Sorted cells were collected for RNA extraction using RNAeasy Kit from Qiagen and RNA quality was assessed using Bioanalyzer. High quality RNA with RIN values greater than 8, were used to generate library using TrueSeq stranded library preparation kit from Illumina following manufacturer’s instructions. Finally, barcoded libraries were pooled, and a final concentration of 10 nM was loaded in HiSeq 2500 Illumina platform and paired-end sequencing for 2*126 cycles were carried out.
