B-cell chronic lymphocytic leukemia (B-CLL) is a heterogenous disease with a highly variable clinical course. Recent studies have shown that expression of the protein tyrosine kinase ZAP-70 may serve as a prognostic marker in B-CLL. Employing a semiquantitative RT-PCR assay, we examined purified leukemia B cells of 39 CLL patients for the expression of(More)
B-cell chronic lymphocytic leukemia (B-CLL) is a heterogenous disease with a highly variable clinical course. Recent studies have shown that expression of lipoprotein lipase (LPL) and ADAM29 may serve as novel prognostic markers in B-CLL. To investigate the prognostic value of these genes, we quantified their expression in peripheral blood mononuclear cells(More)
PRAME is a tumor-associated antigen, which belongs to the family of cancer–testis antigens (CTA). The expression of CTA is mainly restricted to the testis and various tumors. In contrast to other CTA, PRAME expression is also frequently detected in acute and chronic leukemias. Due to this expression pattern, PRAME has attracted great interest as a(More)
B-cell chronic lymphocytic leukaemia (B-CLL) is a heterogenous disease with a highly variable clinical course and analysis of zeta-associated protein 70 (ZAP-70) and CD38 expression on B-CLL cells allowed for identification of patients with good (ZAP-70−CD38−) and poor (ZAP-70+CD38+) prognosis. DNA microarray technology was employed to compare eight(More)
B-cell chronic lymphocytic leukemia (B-CLL) is a heterogeneous disease with a highly variable clinical course. Recent studies have shown that CD38 surface expression on the malignant cell clone may serve as a prognostic marker in that CD38(+) patients with B-CLL are characterized by advanced disease stage, lesser responsiveness to chemotherapy, and shorter(More)
Microarray-based gene expression profiling (GEP) was used to study how stroma modulates the survival of CLL cells in an in vitro coculture model employing the murine fibroblast cell line M2-10B4. CLL cells cultured in direct contact with the stromal layer (STR) showed a significantly better survival than cells cultured in transwell (TW) inserts above the(More)
