Genes rapidly regulated by Ara-C and DNR treatment of HL-60 AML cells and role of NADPH-oxidase derived ROS in DNR-induced gene expression

ABSTRACT: Daunorubicin (DNR) and Cytarabin (Ara-C) are the main chemotherapeutic drugs used for Acute Myeloid Leukemias (AML) treatment. However, their mode of action is not well understood. To decipher if these drug would induce rapid transcriptional reprogramming, we treated HL-60 AML cell line with DNR or Ara-C for 3 hours and carried out a transcriptomic analyses. In addition, we had shown that Reactive Oxigen Species (ROS) produced by NADPH oxidases (NOX) are involved in DNR-induced gene expression. We therefore also performed a transcriptomic analyses in HL-60 cells treated with DNR and VAS2870, an NADPH oxidase inhibitor. HL-60 cells were treated or not for 3 hours with 2 ÂµM Ara-C, 1 ÂµM DNR or 1 ÂµM DNR + 20ÂµM VAS 2870. RNAs were purified from 3 independent experiments and used to probe Affymetrix Human Gene 2.0 ST Genechips

SUMO-2/3 ChIP-Seq in HL-60 cells treated or not with Daunorubicin, Cytarabin and the Nox inhibitor VAS2870

Project description:Acute Myeloid Leukemia cell line HL-60 were treated with 1 M daunorubicin (DNR) or 2M cytarabin (Ara-C) or 1 M DNR + 10 M VAS2870 (NADPH oxidase inhibitor) for 2 hours. ChIP-Seq experiments were carried out with SUMO-2/3 antibodies. Immunoprecipitated DNA and corresponding inputs from 3 independent experiments were pooled and processed for deep-sequencing (Hi-SEq 2000, Illumina).

Gene expression signatures in ex vivo Cytarabine (Ara-C) and Daunorubicin (Dnr) sensitive AML samples

Project description:Wide inter-individual variation in terms of outcome and toxic side effects of treatment exist among patients with AML receiving chemotherapy with cytarabine (Ara-C) and daunorubicin (Dnr). Drug resistance and relapse are considered major causes of treatment failure. Gene expression profiling was undertaken to address possible mechanisms of Ara-C/Dnr resistance. Based on ex vivo Ara-C cytotoxicity at diagnosis, Ara-C sensitive (IC50 <3uM AraC) and Dnr sensitive samples (IC50 < 0.5 uM) (5 samples each) were included for microarray analysis. These were compared with the samples which were drug resistant ex vivo at diagnosis. Our microarray experiment resulted in indentifying differentially expressed genes under ex vivo Ara-C sensitive as well as Dnr sensitive samples compared to ex vivo Drug resistant samples.

RNA-Seq analysis of HL-60 AML cells resistant to daunorubicin or cytarabine

Project description:The Acute Myeloid Leukemia cell line HL-60 was rendered resistant to daunorubicin (DNR) or cytarabine (Ara-C) by continuous exposure to the drug up to concentrations of 30nM for DNR and 100nM for Ara-C. Transcriptomic analysis were then performed by RNA-Seq to compare the cell lines

SUMO2/3 CHIP-Seq in HL-60 cells treated or not with cytarabine or daunorubicine

Project description:SUMOylation, a post-translational modification of the ubiquitin family plays key roles in Acute Myeloid Leukemias response to therapies, in particular through the regulation of gene expression. We have investigated here how daunorubicine (DNR) and cytarabine (Ara-C), the two main drugs used for Acute Myeloid Leukemia treatment, affect the distribution of SUMO on chromatin in the HL-60 cell lines. We found that DNR but not Ara-C leads to a massive decrease in the presence of SUMOylated proteins on the chromatin, in particular at promoters and enhancers, where they are enriched.

SUMOylation controls the rapid transcriptional reprogramming induced by chemotherapies in Acute Myeloid Leukemias

Project description:Genotoxicants have been used for decades as front-line therapies against cancer on the basis of their DNA-damaging actions. However, some of their non-DNA-damaging effects are also instrumental for killing dividing cells. We report here that the anthracycline Daunorubicin (DNR), one of the main drugs used to treat Acute Myeloid Leukemia (AML), induces broad transcriptional changes in AML cells before cell death induction. The regulated genes are particularly enriched in genes controlling cell proliferation and death, as well as inflammation and immunity. These transcriptional changes are preceded by DNR-dependent deSUMOylation of chromatin proteins, which limits both the positive and negative effects of DNR on transcription. Quantitative proteomics shows that proteins that are deSUMOylated in response to DNR are mostly transcription factors, transcriptional co-regulators and chromatin organizers. Among them, the CCCTC-binding factor CTCF is highly enriched at SUMO-binding sites found in cis-regulatory regions. This is notably the case at the promoter of the DNR-induced NFKB2 gene. Its induction is preceded by a SUMO-dependent reconfiguration of chromatin loops engaging its CTCF- and SUMO-bound promoter with distal cis-regulatory regions. Altogether, our work suggests that one of the earliest effects of DNR in AML cells is a SUMO-dependent transcriptional reprogramming.

Gene Expression Analysis of Ara-C Resistance in AML

Project description:Using two independently derived murine BXH2 cell lines, Ara-C resistant derivatives were developed by exposure to increasing concentrations of Ara-C. Microarray analysis comparing the Ara-C resistant cells to their Ara-C sensitive parental cell lines identified potential genes involved in Ara-C resistance.

Gene expression profiling of murine WT and DNR Tregs

Project description:Donminant negative transform growth factor receptor II (DNR) mice were served as a murine primary biliary cirrhrosis model. CD4+Foxp3+ Regulatory T cells (Tregs) play a critical role in self-tolerance and in regulating PBC. In order to determine whether DNR mice derived Tregs processed defective function compared with WT Tregs, CD4+Foxp3+ Treg cells were sorted from DNR and WT mice, respectively, then gene expression analysis was performed by using the Affymetrix GeneChip Mouse Genome 430 2.0 arrays CD4+Foxp3+ Tregs were sorted from the spleen of 10-week-old DNR mice and B6 wild-type mice, respectively. RNA of each sample was then extracted and hybridized on Affymetrix microarrays to detail differences between DNR Tregs and WT Tregs in gene expression.
