Cryptochrome-1 expression: a new prognostic marker in B-cell chronic lymphocytic leukemia

2008

Chronic lymphocytic leukemia is an adult-onset leukemia with a heterogeneous clinical behavior. When chronic lymphocytic leukemia cases were divided on the basis of IgVH mutational status, widely differing clinical courses were revealed. Since IgVH sequencing is difficult to perform in a routine diagnostic laboratory, finding a surrogate for IgVH mutational status seems an important priority. In the present study, we proposed the use of Cryptochrome- 1 as a new prognostic marker in early-stage chronic lymphocytic leukemia. Seventy patients (Binet stage A, without treatment) were included in the study. We correlated Cryptochrome-1 mRNA with well established prognostic markers such as IgVH mu…

BCL6: somatic mutations and expression in early-stage chronic lymphocytic leukemia

2009

BCL6 somatic mutations affect normal and tumoral post germinal center B-lymphocytes. Our objective was to analyse expression, mutations and polymorphisms in the BCL6 gene and to correlate those variables with the clinical outcome in early-stage chronic lymphocytic leukemia (CLL). CLL samples were used for characterisation of the mutational status of BCL6/ immunoglobulin variable heavy chain (IGHV) genes, and expression of BCL6 was determined by real time PCR and immunoblot. Out of 68 cases, 29% show somatic mutations on BCL6 which occur exclusively in IGHV mutated cases. They are single nucleotide substitutions located mainly in two short mutational hot spots. CLL cells express different le…

Analysis of chronic lymphotic leukemia transcriptomic profile: differences between molecular subgroups

2009

B cell chronic lymphocytic leukemia (CLL) is a lymphoproliferative disorder with a variable clinical course. Patients with unmutated IgV(H) gene show a shorter progression-free and overall survival than patients with immunoglobulin heavy chain variable regions (IgV(H)) gene mutated. In addition, BCL6 mutations identify a subgroup of patients with high risk of progression. Gene expression was analysed in 36 early-stage patients using high-density microarrays. Around 150 genes differentially expressed were found according to IgV(H) mutations, whereas no difference was found according to BCL6 mutations. Functional profiling methods allowed us to distinguish KEGG and gene ontology terms showing…
