Analysis of peripheral blood B cells isolated from 41 untreated chronic lymphocytic leukemia (CLL) patients and 11 age-matched control subjects. B-cell CLL is the most common type of leukemia, mainly affecting adults. Results provide insight into molecular mechanisms underlying CLL pathogenesis.

(Submitter supplied) The cellular origin of chronic lymphocytic leukemia (CLL) is debated. Transcriptome analysis of CLL and normal peripheral blood and splenic B cell subsets displayed highest similarity of CLL to mature CD5+ B cells. We identified a distinct CD5+CD27+ post-germinal center B cell subset, and revealed that immunoglobulin V gene mutated CLL are more similar to mutated CD5+ B cells, whereas unmutated CLL are more related to unmutated CD5+ B cells. more...

(Submitter supplied) We conducted a genome-wide DNA methylation analysis in CD19+ B-cells from CLL patient and normal control samples using reduced representation bisulfite sequencing (RRBS). The methylation status of 1.8-2.3 million CpGs in the CLL genome was determined; about 45% of these CpGs were located in more than 23,000 CpG islands (CGIs). While global CpG methylation was similar between CLL and normal B-cells, 1764 gene promoters were identified as being differentially methylated between the two groups. more...

(Submitter supplied) Wnt pathway is dysregulated in CLL-We characterized Wnt pathway gene expression in normal B and CLL-B cells and identified Wnt targets in normal B and CLL-B cells through this data set. In this dataset, we included normal B cells and CLL-B cells for Wnt pathway gene expression. This leads to the identification of 62 Wnt pathway components which are differnetially expressed between normal and CLl-B cells. more...

(Submitter supplied) Prospective series of 136 clinical monoclonal B lymphocytosis (cMBL) and 216 chronic lymphocytic leukemia (CLL) Rai 0 patients, were investigated in this study. While the distribution of CD38 and ZAP-70 positivity was similar, IGHV-mutated cases were more frequent among cMBL (P = 0.005). A Cox multivariate analysis on the whole patient cohort showed that cMBL condition was predictive of longer PFS, while CD38 expression and IGHV-unmutated status and CD38 expression correlated significantly with a shorter PFS in cMBL and Rai0-CLL, respectively. more...

(Submitter supplied) Chronic lymphocytic leukemia (CLL) is a clinically heterogeneous disease characterized by chromosomal aberrations of prognostic significance. Recent studies showed that gain of chromosome 2p is a recurrent lesion in CLL. We investigated the 2p gain and its relationship with prognostic biomarkers in a prospective series of 287 early-stage CLLs (Binet A). The 2p gain was detected by FISH in 17 patients (6%) and further characterized by single nucleotide polymorphism-array. more...

(Submitter supplied) The T-box transcription factor T-bet is encoded by Tbx21 and was identified to play a role in aging and tissue localization of B cells. T-bet expression was detected in malignant B cells but its potential role in B-cell malignancies remains largely unexplored. We used single cell RNA sequencing (scRNA-seq) and the assay for transposase accessible chromatin using sequencing (scATAC-seq) to analyze the regulatory role of T-bet in TCL1 leukemia.

(Submitter supplied) In chronic lymphocytic leukemia (CLL) a diverse set of genetic mutations is embedded in a deregulated epigenetic landscape that drives cancerogenesis. To elucidate the role of aberrant chromatin features, we mapped DNA methylation, 7 histone modifications, nucleosome positions, chromatin accessibility, binding of EBF1 and CTCF as well as the transcriptome of B cells from CLL patients and healthy donors. more...
