Project description:To determine interactors of Aurora-A, HA tagged Aurora-A was immunoprecipitated from MV4-11 cells stably expressing HA tagged Aurora-A wild type and compared to MV4-11 cells expressing empty vector.
Project description:Enhanced homing and uncontrolled expansion are the characteristics of AML cells. We identified a transcription factor FEV (fifth Ewing variant) as the regulator. To assess the regulation mechanisms, FEV expression was knocked down in AML cell line MV4-11 cells using shRNA. MV4-11 cells transduced with non-silencing control (NC), FEV shRNA (shFEV) were cultured for 3 days and sorted by FACS. The cells were collected and total RNA was isolated by the Trizol kit (Takara Bio, Otsu, Japan) according to manufacturer’s protocol. High-throughput RNA sequencing (RNA-seq) was performed by Illumina HiSeq 2500 (Illumina, San Diego, CA) at CapitalBio Corporation (Beijing, China). Differentially expressed genes were analysed between the two groups.
Project description:Our gene set analysis of MV4-11-R versus MV4-11 indicated decreased depolarization of mitochondria and mitochondrial membrane, mitochondrial dysfunction and anti-apoptosis as other top ranked molecular or cellular functions of differential gene sets. expression of most genes encoding glycolytic enzymes was up-regulated in MV4-11-R cells we revealed a metabolic alteration in sorafenib-resistant cell lines with mitochondrial respiration deficiency, leading to substantial decrease of mitochondria-derived ATP generation and a significant increase in glycolytic activity to maintain sufficient ATP production. Our study revealed a metabolic signature of sorafenib resistance and indicated that increase of glycolytic activity including upregulation of major glycolytic enzymes may be viewed as a marker for early detection of sorafenib resistance in AML patients with FLT3/ITD mutation and glycolytic inhibitors warrant further investigation as alternative therapeutic agents for sorafenib-resistant cells Sorafenib resistant cells MV411-R VS. parental MV4-11 cells. Biological replicates: 3 control replicates, 3 treated replicates.

Project description:To investigate the effect of decitabine on CD36/NFkB/TLR signaling pathway in MV4-11 cells, and to explore the CD36-dependent signaling pathway regulated by decitabine. We then performed gene expression profiling analysis using data obtained from RNA-seq of 2 different cells at two different treatment.
Project description:Pharmacological inhibition of the SMARCA4 bromodomain inhibited human leukemic cell proliferation, phenocopying SMARCA4 knockdown in these cells. We performed microarray analysis of global gene expression changes in MV4-11 cells after 6 days of PFI-3 treatment and after SMARCA4 knock-down. With this analysis we identified several genes whose expression was similarly up- or down-regulated upon inhibitor treatment and SMARCA4 depletion. Human acute monocytic leukemia cells (MV4-11, ACC 102) were lentivirally transduced with shRNA taregting SMARCA4 (KD) or with a negative control shRNA (Scr). In a parallel experiment MV4-11 cells were treated for 6 days with 10 uM PFI-3, which is SMARCA4, SMARCA2 and PBRM1 bromodomain inhibitor, or DMSO as a negative control. All sample types were prepared in triplicates.
Project description:A novel hypomethylating agent NTX-301 is a promising therapeutic agent for AML patients. To examine its mechanisms of action, we produced gene expression data upon treatment with NTX-301 or decitabine (DAC) in MV4-11 cell line.
Project description:The expression level of microRNAs in FLT3-ITD+ AML is unknown. Using empty vector (EV) lentiviral CRISPR-Cas9 infected FLT3-ITD+ AML cell lines (MV4-11 cells), we performed next generation RNA sequencing on small RNAs to determine microRNA expression level in these cells. We found a variety of evolutionarily conserved and non-conserved microRNAs expressed in our cells of interest. Small RNAseq on EV lentiviral CRISPR-Cas9 infected MV4-11 cell lines was performed on triplicate cultures.
