Project description:The transcriptional profile of the human multiple myeloma (MM) cell line MM.1S treated with MLN4924 vs control MM.1S cells was characterized by oligonucleotide microarray analysis, using the human U133 plus 2.0 Affymetrix GeneChip, according to previously described protocols for total RNA extraction and purification; cDNA synthesis; in vitro transcription reaction for production of biotin-labeled cRNA; hybridization of cRNA with U133plus2.0 Affymetrix gene chips; and scanning of image output files. Scanned image output files were analyzed using DNA-Chip Analyzer (dChip) (www.dchip.org), including conversion to DCP files, normalization and modeling. The gene expression profile of MM.1S cells for each time point of MLN4924 treatment was compared to the profile of control MM.1S cells. The NEDD8 activating enzyme (NAE) is upstream of the 20S proteasome in the ubiquitin/proteasome pathway and catalyzes the first step in the neddylation pathway. NEDD8 modification of cullins is required for ubiquitination of cullin-ring ligases (CRLs), which regulate degradation of a distinct subset of proteins. The more targeted impact of NAE on protein degradation prompted us to study MLN4924, an investigational NAE inhibitor, in preclinical multiple myeloma (MM) models. In vitro treatment with MLN4924 led to dose-dependent decrease of viability in a panel of human MM cell lines. In this analysis, we evaluated the molecular changes triggered in MM.1S myeloma cells by their in vitro treatment with MLN4924. The transcriptional profiles of each experimental condition were characterized by oligonucleotide microarray analysis, using the human U133 plus 2.0 Affymetrix GeneChip. The human multiple myeloma (MM) cells MM.1S were cultured in vitro in the presence or absence of the NEDD8 activating enzyme (NAE) inhibitor MLN4924 for 8, 16 or 24hrs. The gene expression profiles of drug treated cells were compared with the profiles of control MM.1S cells.

Project description:This study provides a genome-wide map of changes in degradative ubiquitination in response to proteasome inhibition in the multiple myeloma cell line MM.1S. Following proteasome inhibition with lactacystin, CUT and RUN assays were carried out to determine the genomic locations of ubiquitin in multiple myeloma cells stably expressing a flagged version of ubiquitin (MM.1S-3XFlag Ubiquitin cells). In addition, we report the DNA binding locations of the transcription factor c-MYC in basal conditions in MM.1S parental cells.

Project description:Multiple myeloma (MM) evolves from highly prevalent premalignant condition termed Monoclonal Gammopathy of Undetermined Significance (MGUS). We report an MGUS-MM phenotype arising in transgenic mice with Emu-directed expression of the unfolded protein/ER stress response and plasma cell development spliced isoform factor XBP-1s. Emu-XBP-1s elicited elevated serum Ig and IL-6 levels, skin alterations and with advancing age, a significant proportion of Emu-xbp-1s transgenic mice develop features diagnostic of human MM including bone lytic lesions. Transcriptional profiles of Emu-xbp-1s B lymphoid and MM cells show aberrant expression of genes known to be dysregulated in human MM including Cyclin D1, MAF, MAFB, and APRIL. This genetic model coupled with documented frequent XBP-1s overexpression in human MM serve to implicate chronic XBP-1s dysregulation in the development of this common and lethal malignancy.
