Project description:In this experiment we demonstrate the use of an inhibitor of the KDM5 family of histone demethylases, KDM5-C70, on H3K4me3 marks in the multiple myeloma cell line MM1S. KDM5-C70 increases H3K4me3 in a global fashion across the genome. Examination of H3K4me3 mark across MM1S cells treated with either KDM5-C70 or vehicle control

Project description:To determine which genes affected by loss of KDM5 in adults were direct targets, we carried out KDM5 ChIP-seq analyses. To valide this data, we utilized a previously generated fly strain in which the sole source of KDM5 is from a transgene expressing an HA tagged form of KDM5 expressed under the control of its endogenous promoter. Comparing genome-wide gene expression and KDM5 binding analyses in Drosophila adults, we demonstrate the primary function of KDM5 in adults is to activate gene expression KDM5. To investigate the link between KDM5 and H3K4me3, we carried out anti-H3K4me3 ChIP-seq from wildtype adults . Genome-wide, KDM5 and H3K4me3 peaks showed a similar distribution, with both peaking at the transcription start site (TSS) showed a striking overlap with the presence of H3K4me3.

Project description:Here we report the use of high-throughput sequencing technologies (RNA-seq, ATAC-seq, ChIP-seq) to identify the molecular programme of the transcirption factor c-MAF (MAF) in parental (MM1.S, JJN3, H929), MAF-depleted (MM1S, JJN3) and MAF-overexpressing (MM1S, U266) multiple myeloma (MM) cells . We performed chromatin immunoprecipitation followed by sequencing (ChIP-seq) against MAF in naive MM cells , and against MAF, H3K27ac and H3K4me1 in MAF-overexpressing cells. Assay for Transposase-Accessible Chromatin with high-throughput sequencing (ATAC-seq) was performed on MAF-overexpressing U266 myeloma cells. In addition, we identifed the transcriptome of MAF-depleted myeloma cells 3 days after lentiviral transduction with MAF-targeting shRNA and scbl control. Our integrated -omics approach provides a comprehensive characterization of the role and function of MAF in myeloma cells and provides novel insights towards the discovery and design of molecular targets for precision therapy against MAF-overexpressing MM.

Project description:Here we report the use of high-throughput sequencing technologies (RNA-seq, ChIP-seq) to identify the molecular programme of PBX1 and FOXM1 in multiple myeloma cells (MM1S, U266 cell lines). We performed Chromatin Immunoprecipitation followed by sequencing (ChIP-seq) against PBX1 in MM1S and U266 cells (n=2). In addition, we identifed the transcriptome of PBX1-depleted and FOXM1-depleted myeloma cells 3 days after transduction with shRNA-expressing lentiviral vectors. Molecular characterization revealed PBX1 as a novel epigenetic regulator of myeloma cell survival and proliferation. PBX1 directly and unilaterally controls the FOXM1 transcriptional programme and, together,they regulate the high-risk transcriptional signature of chr1q-amplified cells. Pharmacological inhibition of the unified PBX1-FOXM1 axis with thiostrepton showed selectivity against chr1q-amplified MM. Altogether, these data reveal PBX1-FOXM1 axis as a novel therapeutic avenue against chr1q-amplified MM.

Project description:The project aims at identifying surface proteins that are modified by the tetrasaccharide sialyl Lewisa/x and therefore serve as selectin ligands in Multiple Myeloma. To that end, we have performed an immunoprecipitation using the Heca452 antibody (which recognizes sialyl Lewisa/x-related structures) and a matched isotype control on membrane-enriched fractions that have been generated from the sialyl Lewisa/x-enriched and parental Multiple Myeloma cell line MM1S and RPMI8226. Using this approach, we have been able to identify candidate proteins that may function as selectin ligands in myeloma.

Project description:To investigate ferroptosis-dependent changes in DNA methylation, a genome wide DNA methylation profiling of ferroptotic (RSL3-treated) multiple myeloma cells (MM1S & MM1R) was performed using the 850K MethylationEPIC BeadChip Array. The ferroptotic DNA methylation signature was compared to myeloma cells pre-treated with the ferroptosis inhibitor ferrostatin-1 (FRSL3), which served as a negative control. In total, three biological replicates per treatment per cell line were included.

Project description:We have used an agnostic approach to identify drug combinations by using combination high throughput screening (cHTS) technology and make the surprising discovery that adenosine A2A and beta-2 adrenergic receptor agonists are highly synergistic, selective and novel agents that enhance glucocorticoid activity in B-cell malignancies. We used the microarray study to understand the synergistic mechanism between dexamethasone and A2A receptor agonist or Beta-2 Adrenergic receptor agonist in a multiple myeloma cell line, MM1S. MM1S cells were treated with CGS-21680 or Salmeterol alone, or in combination with dexamethasone for six hours for RNA extraction and hybridization on Affymetrix microarrays.
