TranscriptomicsAssessment of MEK-ERK pathway targeting by BRAF, NRAS and KRAS gene mutations in plasma cell dyscrasias [Patient samples]
Multiple myeloma (MM) is a malignant disorder characterized by the clonal proliferation of plasma cells (PCs) in the bone marrow (BM). The genetic background and clinical course of the disease are largely heterogeneous, and MM pathophysiology ranges from the premalignant condition of monoclonal gamm...

TranscriptomicsThe HDAC inhibitor Givinostat modulates key hematopoietic genes in JAK2V617F cells, affecting proliferation, differentiation and apoptosis
We investigated the mechanism of action of the HDAC inhibitor Givinostat in JAK2V617F cells. We confirm that the drug inhibits colony formation and proliferation and induces apoptosis at doses 2-3 fold lower in JAK2V617F (HEL, UKE1 and SET2) compared to JAK2 wild type cell lines (K562, KU812, THP1 a...

TranscriptomicsInactivation of the exosome ribonuclease DIS3 triggers the pluripotency factor LIN28B, repressing let-7 miRNAs and unleashing MYC and RAS.
Somatic mutations affecting DIS3, the catalytic component of the RNA exosome, have been found in up to 18% of patients affected by the hematological cancer multiple myeloma. Here we show that DIS3 targets and degrades the pluripotency factor LIN28B. In cancer cells, DIS3 inactivation leads to enhanc...

TranscriptomicsIdentification of MicroRNA Expression Patterns and a MicroRNAs/mRNA Regulatory Network in Multiple Myeloma
To date, little evidence of miRNA expression/deregulation in multiple myeloma (MM) has been reported. To characterize miRNA expression profiling of MM plasma cells (PCs) and integrate miRNA expression data with other molecular features of MM patients, global miRNA expression profiles were generated ...

TranscriptomicsIntegrated genomics approach to detect allelic imbalances in multiple myeloma, SNP data
A SNP microarray and FISH-based procedure to detect allelic imbalances in multiple myeloma: an integrated genomics approach reveals a wide dosage effect on gene and microRNA expression Multiple myeloma (MM) is characterized by marked genomic instability. Beyond structural rearrangements, a relevant...

TranscriptomicsReconstruction of microRNA/genes transcriptional regulatory networks of multiple myeloma through in silico integrative genomics analysis [MM, miRNA]
The identification of deregulated miRNA in multiple myeloma (MM) has progressively added a further level of complexity to MM biology. In the present study, we take virtue of in silico integrative genomics analysis to generate an unprecedented global view of the transcriptional regulatory networks mo...

TranscriptomicsGenomic profiling of enzastaurin-treated B cell lymphoma RL cells
Follicular lymphoma (FL) is an indolent lymphoma associated with follicular center B cells, and typically contains the Bcl-2 chromosomal translocation t(14;18), which leads to overexpression of the anti-apoptotic intracellular protein Bcl-2. FLs are sensitive to chemotherapy; however, patient relaps...
