(Submitter supplied) Bendamustine is a commonly-used drug to treat CLL patients. Because drug-responses among the patients are heterogeneous, we wanted to find candidate genes to predict sensitivity to the compound We used microarrays to find genes whose expression correlates with the in vitro induced-cytotoxcity by a 24-hour incubation with bendamustine 25 µm

(Submitter supplied) Mesenchymal stem cells (MSCs) are known to induce the conversion of activated T-cells into regulatory T-cells in vitro. The marker CD69 is a target of canonical NF-κB signaling and is transiently expressed upon activation; however, stable CD69 expression defines cells with immunoregulatory properties. Given its enormous therapeutic potential, we explored the molecular mechanisms underlying the induction of regulatory cells by MSCs. more...

(Submitter supplied) Comparison of Chronic Lymphocytic Leukemia patients expressing high or low levels of ZAP70 mRNA: prognostic factors and interaction with the microenvironment. Zeta-associated protein 70 (ZAP70) is a widely recognized prognostic factor in chronic lymphocytic leukemia (CLL), but mechanisms by which its higher expression leads to a poor outcome remain to be fully explained. In an attempt to unveil unfavorable cellular properties linked to high ZAP70 expression, we used gene expression profiling to identify genes associated with disparities in B-cells from CLL patients expressing high versus low ZAP70 mRNA, measured by quantitative real-time PCR. more...

(Submitter supplied) UGT2B17 is a recently identified molecular marker for poor prognosis and drug response in Chronic Lymphocytic Leukemia (CLL), which is the most prevalent adult leukemia subtype in the western world. The goal of this study was to investigate transcriptome changes associated with drug-induced UGT2B17 up-regulation to identify possible upstream regulators of drug response and downstream effects of UGT induction.

(Submitter supplied) Chronic lymphocytic leukemia (CLL) is characterized by the accumulation of CD5+ B lymphocytes in peripheral blood, lymphoid organs and BM. The main feature of the disease is accumulation of the malignant cells due to decreased apoptosis. CD84 belongs to the Signaling Lymphocyte Activating Molecule (SLAM) family of immunoreceptors, and has an unknown function in CLL cells. Here, we show that the expression of CD84 is significantly elevated from the early stages of the disease, and is regulated by macrophage migration inhibitory factor (MIF) and its receptor, CD74. more...

(Submitter supplied) The clinical course of patients with chronic lymphocytic leukemia (CLL) is heterogeneous. Several prognostic factors have been identified that can stratify patients into groups that differ in their relative tendency for disease progression and/or survival. Here, we pursued a subnetwork-based analysis of gene expression profiles to discriminate between groups of patients with disparate risks for CLL progression. more...

(Submitter supplied) Today’s diagnostic tests for multiple myeloma (MM) reflect the criteria of the updated WHO classification based on biomarkers and clinicopathologic heterogeneity. To that end, we propose a new subtyping of myeloma plasma cells (PC) by B-cell subset associated gene signatures (BAGS), from the normal B-cell hierarchy in the bone marrow (BM). To do this, we combined FACS and GEP data from normal BM samples to generate classifiers by BAGS for the PreBI, PreBII, immature (Im), naïve (N), memory (M) and PC subsets. more...

(Submitter supplied) Mononuclear cells were isolated from the sternal bone marrow and prepared for multiparametric flow cytometry using an optimized and validated protocol. B-cell subsets of PreBI, PreBII, Immature, Naive, Memory and Plasma cells were isolated and a al of 38 gene expression profiles were generated using the HuEx-1_0-st-v2-micro array chip from Affymetrix to characterize the gene expression in the individual subpopulations.

We propose a refined classification sys-tem based on subset-specific B-cell–associated gene signatures (BAGS) in the normal B-cell hierarchy, hypothesizing that it can provide new biologic insight and diagnostic and prognostic value. more...

(Submitter supplied) Purpose: It has been proposed that vitamin D may play a role in prevention and treatment of cancer while epidemiological studies have linked vitamin D insufficiency to adverse disease outcome in chronic lymphocytic leukemia (CLL). However, the underlying mechanisms have not yet been revealed. In this study, we sought to identify key signaling pathways and molecules that are altered after calcitriol, the biologically active form of vitamin D, supplementation of CLL cells in vitro. more...
