(Submitter supplied) A rare complication of multiple myeloma is a secondary extramedullary involvement, and the skin is one of the possible sites, due to the physiological homing of plasma cells (PCs) into the skin. The article reports a case of a relapsed refractory MM patient, who developed a cutaneous localization after 16 months from the diagnosis under Bortezomib treatment without a leukemic phase. Patient was refractory to Bortezomib. more...

(Submitter supplied) To determine the mechanisms of the initial extramedullary translocation of myeloma cells from bone marrow into peripheral blood. We found that the clonal cPCs were more frequently detected by flowcytometry in extramedullary plasmacytoma patients and worsened their prognosis. It is technically much easier to collect single cPCs using FACS than it is to perform EMP biopsy. Combining imaging extramedullary plasmacytoma diagnosis and cPCs detection may be a promising strategy for prognostic stratification. more...

(Submitter supplied) Multiple myeloma (MM) is a cancer of malignant plasma cells in the bone marrow and extramedullary sites. We previously characterized a VQ model for human high-risk MM. Different VQ lines display distinct disease phenotypes and survivals, suggesting significant intra-model variation. Here, we use whole exome sequencing and copy number variation (CNV) analysis coupled with RNA-Seq to stratify VQ lines into corresponding clusters: Group A cells had monosomy chr5 and overexpressed genes and pathways associated with sensitivity to bortezomib (Btz) treatment in human MM patients. more...

(Submitter supplied) Virtually all patients with multiple myeloma become unresponsive to treatment over time. Relapsed/refractory multiple myeloma (RRMM) is accompanied by the clonal evolution of myeloma with heterogeneous genomic aberrations and profound changes of the bone marrow microenvironment (BME). However, the molecular mechanisms that drive drug resistance remain elusive. Here, we have analyzed the heterogeneous tumor cell population of 20 RRMM patients and its complex interaction network with the BME by single cell RNA-sequencing before/after treatment. more...

(Submitter supplied) In this study, we performed scRNA-seq analyses of bone marrow mononuclear cells (BM-MNCs) in patients with MM receiving bortezomib-based treatments to investigate following questions; (i) the compositional differences in BM-MNCs between normal control and MM patients, and between good and poor responder groups, and (ii) the genes and the cell-to-cell communication networks associated with the treatment responsiveness.

(Submitter supplied) To understand the biological mechanism of ELL2 in multiple myeloma (MM), we show that the MM risk allele lowers ELL2 expression in CD138+ plasma cells (Pcombined=2.5×10-27; bcombined=-0.24 s.d.), but not in peripheral blood or other tissues. Consistent with this, several variants representing the MM risk allele map to regulatory genomic regions, and three yield reduced transcriptional activity in plasmocytoma cell lines. more...

(Submitter supplied) Multiple myeloma is a plasma cell malignancy almost always preceded by precursor conditions, but low tumor burden of these early stages has hindered the study of their molecular programs through bulk sequencing technologies. Here, we generated and analyzed single cell RNA-sequencing of plasma cells from 26 patients at varying disease stages and 9 healthy donors. In silico dissection and comparison of normal and transformed plasma cells from the same bone marrow biopsy enabled discovery of novel, patient-specific transcriptional changes. more...
