GCET1 (germinal center B cell-expressed transcript-1) gene codes for a serpin expressed in germinal center (GC) B cells. Following the observation that follicular lymphoma cases exhibit an increased level of Gcet1 expression, compared with follicular hyperplasia, we have characterized Gcet1 protein expression in human tissues, cell lines, and a large series(More)
Mantle cell lymphoma (MCL) is a prototypical neoplastic disease in which a common cytogenetic alteration, t11;14, leading to cyclin D1 overexpression, is associated with other changes that need to be considered in an explanation of the clinical, morphological, and molecular variability of this disease. Using a cDNA microarray (Oncochip-CNIO) containing(More)
Splenic marginal zone lymphoma (SMZL) is a newly recognized lymphoma type whose precise molecular pathogenesis is still essentially unknown. This hampers differential diagnosis with other small B-cell malignancies. With the aim of characterizing this tumor more comprehensively, and of identifying new diagnostic and prognostic markers, we performed cDNA(More)
Ecteinascidin 743 (ET-743; Yondelis, Trabectedin) is a marine anticancer agent that induces long-lasting objective remissions and tumor control in a subset of patients with pretreated/resistant soft-tissue sarcoma. Drug-induced tumor control is achievable in 22% of such patients, but there is no clear indication of the molecular features correlated with(More)
Diffuse large B-cell lymphoma (DLBCL) prognostication requires additional biologic markers. miRNAs may constitute markers for cancer diagnosis, outcome, or therapy response. In the present study, we analyzed the miRNA expression profile in a retrospective multicenter series of 258 DLBCL patients uniformly treated with chemoimmunotherapy. Findings were(More)
BACKGROUND Immunoglobulin gene somatic hypermutation is a biologically relevant and clinically useful prognostic factor in different types of low-grade B-cell lymphomas, including chronic lymphocytic leukemia, mantle cell lymphoma and splenic marginal zone lymphoma. DESIGN AND METHODS With the aim of identifying surrogate markers of somatic hypermutation,(More)
Gene-expression profiling in B-cell lymphomas has provided crucial data on specific lymphoma types, which can contribute to the identification of essential lymphoma survival genes and pathways. In this study, the gene-expression profiling data of all major B-cell lymphoma types were analyzed by unsupervised clustering. The transcriptome classification so(More)
Targeted treatment of advanced melanoma could benefit from the precise molecular characterization of melanoma samples. Using a melanoma-specific selection of 217 genes, we performed targeted deep sequencing of a series of biopsies, from advanced melanoma cases, with a Breslow index of ≥ 4 mm, and/or with a loco-regional infiltration in lymph nodes or(More)
MicroRNAs (miRNAs) have negative effects on gene expression and are major players in cell function in normal and pathological conditions. Epstein-Barr virus (EBV) infection of resting B lymphocytes results in their growth transformation and associates with different B cell lymphomas. EBV-mediated B cell transformation involves large changes in gene(More)
