Predictors of chronic lymphocytic leukaemia (CLL) transformation to Richter syndrome (RS) are not established and were investigated in 185 consecutive CLL cases. Actuarial incidence RS (n = 17; all diffuse large B-cell lymphomas) at 10 years was 16.2% (95% confidence interval: 8.0-24.4%). At diagnosis, prognosticators by univariate analysis IGHV homology >/=98% (P 0.006), IGHV4-39 usage < 0.001), del13q14 absence 0.004), expression CD38 0.001) ZAP70 size number lymph nodes, advanced Binet...

Although CD49d is an unfavorable prognostic marker in chronic lymphocytic leukemia (CLL), definitive validation evidence lacking. A worldwide multicenter analysis was performed using published and unpublished CLL series to evaluate the impact of as overall (OS) treatment-free survival (TFS) predictor.A training/validation strategy chosen find optimal cutoff. The hazard ratio (HR) for death treatment imposed by estimated pooled 2,972 CLLs; Cox stratified center stage used adjust confounding...

CD38 and CD49d are associated negative prognosticators in chronic lymphocytic leukemia (CLL). Despite evidence that both molecules involved interactions occurring between CLL normal cells the context of CLL-involved tissues, a functional link is still missing. Using gene expression profiles comparing CD38(+)CD49d(+) versus CD38(-)CD49d(-) cells, we showed overexpression CCL3 CCL4 chemokines from former group. These were also up-regulated by signals CLL; moreover, was expressed bone marrow...

Abstract Purpose: Activation of the PI3K/mTOR signaling pathway is recurrent in different lymphoma types, and pharmacologic inhibition has shown activity patients. Here, we extensively characterized vitro vivo mechanism action PQR309 (bimiralisib), a novel oral selective dual inhibitor under clinical evaluation, preclinical models. Experimental Design: This study included screening on large panel cell lines, both as single agent combination, validation experiments models primary cells,...

The Bruton’s tyrosine kinase (BTK) inhibitor ibrutinib, which antagonizes B cell receptor (BCR) signals, demonstrates remarkable clinical activity in chronic lymphocytic leukemia (CLL). lymphocytosis experienced by most patients under ibrutinib has previously been attributed to inhibition of BTK-dependent integrin and chemokine cues operating retain the tumor cells nodal compartments. Here, we show that VLA-4 integrin, as expressed CD49d-positive CLL, can be inside-out activated upon BCR...

Abstract Loss-of-function mutations in NFKBIE, which encodes for the NF-κB inhibitor IκBε, are frequent chronic lymphocytic leukemia (CLL) and certain other B-cell malignancies have been associated with accelerated disease progression inferior responses to chemotherapy. Using vitro vivo murine models primary patient samples, we now show that NFKBIE-mutated CLL cells selected by microenvironmental signals activate pathway induce alterations within tumor microenvironment can allow immune...

The balanced activity of microtubule-stabilizing and -destabilizing proteins determines the extent microtubule dynamics, which is implicated in many cellular processes, including adhesion, migration, morphology. Among destabilizing proteins, stathmin overexpressed different human malignancies has been recently linked to regulation cell motility. observation that was recurrent metastatic sarcomas prompted us investigate contribution tumor local invasiveness distant dissemination. We found...

A fraction of chronic lymphocytic leukaemia (CLL) cases carry highly homologous B-cell receptors (BCR), i.e. characterized by non-random combinations immunoglobulin heavy-chain variable (IGHV) genes and complementarity determining region-3 (HCDR3), often associated with a restricted selection IGVK/L light chains. Such 'stereotyped' BCR occur more frequently in CLL unmutated (UM) than mutated (M) IGHV genes. We analysed 1426 IG rearrangements (from 1398 cases) clustering driven HCDR3...

Significance CLL is characterized by autonomous B cell receptor (BCR) signaling. subsets are empirically defined sequence similarities of the BCR heavy chain. However, in unfavorable subset 2, an acquired mutation (termed R110) light chain stimulates This study demonstrates that oncogenic R110 dictates prognosis and not restricted to conventional 2. Interestingly, carriers a particular light-chain allele ( IGLV3-21 * 01 ) predisposed develop because this enables signaling as single-point...

Abstract Cancer heterogeneity at the proteome level may explain differences in therapy response and prognosis beyond currently established genomic transcriptomic-based diagnostics. The relevance of proteomics for disease classifications remains to be clinically heterogeneous cancer entities such as chronic lymphocytic leukemia (CLL). Here, we characterize transcriptome alongside genetic ex-vivo drug profiling a annotated CLL discovery cohort (n = 68). Unsupervised clustering data reveals six...

In chronic lymphocytic leukemia the balance between pro-apoptotic and anti-apoptotic members of bcl-2 family is involved in pathogenesis, chemorefractoriness clinical outcome. Moreover, recently proposed anti-bcl-2 molecules, such as ABT-199, have emphasized potential role proteins context target therapies. We investigated bax/bcl-2 ratio by flow cytometry 502 patients identified a cut off 1.50 to correlate with well-established biological prognosticators. Bax/bcl-2 was or over 263 (52%)...

Abstract Purpose: In chronic lymphocytic leukemia (CLL), TP53 mutations are associated with reduced survival and resistance to standard chemoimmunotherapy (CIT). Nevertheless, the clinical impact of subclonal below 10% 15% variant allele frequency (VAF) remains unclear. Experimental Design: Using a training/validation approach, we retrospectively analyzed biological features above (high-VAF) or (low-VAF) previously reported 10.0% VAF threshold, as determined by deep next-generation...
