Systems medicine dissection of chromosome 1q amplification reveals a novel PBX1-FOXM1 axis for targeted therapy in multiple myeloma

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.

Effect of forkhead box M1 in multiple myeloma

Project description:Forkhead Box M1 (FOXM1) is a promising molecular target for high-risk multiple myeloma and relapse and refractory myeloma, but whether FOXM1 is essential in myeloma has not yet been established. To address this knowledge gap, we used Western blotting to measure FOXM1 protein levels in 11 human myeloma cell lines (HMCLs) and then chose the two lines expressing the largest amount of the transcription factor, OPM2 and Delta47, for gene editing using CRISPR-Cas9. In both cases, two independent FOXM1-deficient daughter lines, designated KO-1 and KO-2, were generated. They contained 2 different 10-bp deletions at the target site of their respective guide RNA in case of OPM2 and a 10-bp deletion and 1-bp insertion in case of Delta47. Western analysis confirmed the lack of FOXM1 in all knockout clones. FOXM1-deficient myeloma cells proliferated more slowly than their parental counterparts containing normal levels of FOXM1. Moreover, we added back FOXM1 to FOXM1-KO cells by transfection of a constitutively expressed FOXM1c cDNA gene. The reconstituted OPM2 and Delta47 cells, designated FOXM1 KO-R contained high amounts of FOXM1 protein. Here, we used these cell lines to investigate the role of FOXM1 in regulating the gene expression in multiple myeloma.

Serum protein N-glycosylation changes in multiple myeloma

Project description:<h4><strong>BACKGROUND:</strong> Multiple myeloma is characterized by clonal proliferation of malignant plasma cells in the bone marrow that produce monoclonal immunoglobulins. N-glycosylation changes of these monoclonal immunoglobulins have been reported in multiple myeloma, but previous studies only detected limited serum N-glycan features.</h4><h4><strong>METHODS:</strong> Here, a more detailed study of the human serum N-glycome of 91 multiple myeloma patients and 51 controls was performed. We additionally analyzed sequential samples from patients (n = 7) which were obtained at different time points during disease development as well as 16 paired blood serum and bone marrow plasma samples. N-glycans were enzymatically released and measured by mass spectrometry after linkage specific derivatization of sialic acids.</h4><h4><strong>RESULTS:</strong> A decrease in both α2,3- and α2,6-sialylation, galactosylation and an increase in fucosylation within complex-type N-glycans were found in multiple myeloma patients compared to controls, as well as a decrease in difucosylation of diantennary glycans. The observed glycosylation changes were present in all ISS stages, including the 'low-risk' ISS I. In individual patients, difucosylation of diantennary glycans decreased with development of the disease. Protein N-glycosylation features from blood and bone marrow showed strong correlation. Moreover, associations of monoclonal immunoglobulin (M-protein) and albumin levels with glycan traits were discovered in multiple myeloma patients.</h4><h4><strong>CONCLUSIONS & GENERAL SIGNIFICANCE: </strong>In conclusion, serum protein N-glycosylation analysis could successfully distinguish multiple myeloma from healthy controls. Further studies are needed to assess the potential roles of glycan trait changes and the associations of glycans with clinical parameters in multiple myeloma early detection and prognosis.</h4>
