Megjegyzések:	The expression of apoptosis-related genes BCL2, BAX, BCL2L1, BCL2A1, MCL1, DAPK1 and MYC was studied by quantitative real-time polymerase chain reaction on total RNA samples from patients with acute lymphoblastic leukaemia (ALL, n = 16), acute myeloid leukaemia (AML, n = 27), chronic myeloid leukaemia (CML, n = 12), mantle cell lymphoma (MCL, n = 19) and chronic lymphoid leukaemia (CLL, n = 32). BCL2, BAX, BCL2A1, MCL1, DAPK1 and MYC were overexpressed in all patient groups. BCL2L1 was underexpressed in CLL and CML, but not in AML, ALL and MCL. MCL1 levels were significantly higher in CD13 and CD33-positive ALL, and in CD56-positive AML samples. BCL2, BCL2L1, BCL2A1 and MCL1 were overexpressed and DAPK1 was underexpressed in CLL samples with a 11q23 deletion. MYC overexpression was significantly associated with shorter overall survival in MCL (P < 0.01). AML patients with a normal karyotype showed a higher frequency of BCL2A1 overexpression (P < 0.001) than those with an abnormal karyotype.

Cím:	RAF-1 over-expression does condition survival of patients affected by aggressive mantle cell lymphoma / Nagy Bálint, Galimberti Sara, Benedetti Edoardo, Caracciolo Francesco, Pacini Simone, Vilpo Juhani, Ferrer Anna, Elonen Erkki, Franssila Kaarle, Knuutila Sakari, Petrini Mario

Megjegyzések:	Our results show over-expression of RAF-1 in MCL versus tonsilar B-cell population. The absence of significance versus normal bone marrows could be related to variability of neoplastic infiltration and, perhaps, to the microenvironment, that in MCL would be particularly relevant [11].The observation of a clinical prognostic significance of RAF-1 would be useful in the stratification of cases on the basis of a "biological risk".This would be particularly relevant in the context of the R-Hyper-CVAD regimen that, notwithstanding its high clinical efficacy (even in the eradicating minimal residual disease) has a not negligible toxicity (in our series, 30% of infective complications, with two patients who died because of sepsis).Consequently, if the prognostic role of RAF-1 over-expression will be confirmed in larger series of patients, different therapeutic strategies would be adopted in the treatment of MCL.In this line, Sorafenib, an oral multi-kinase inhibitor that targets also RAF kinases would be an interesting compound [12] for treatment of mantle cell lymphoma.

Cím:	Lymphotoxin [béta] expression is high in chronic lymphocytic leukemia but low in small lymphocytic lymphoma : a quantitative real-time reverse transcriptase polymerase chain reaction analysis / Bálint Nagy, Anna Ferrer, Marcelo L.

Megjegyzések:	The lymphotoxin beta (LTB) gene, localized to the major histocompatibility complex region on chromosome 6p21.3, has an important role in the formation of germinal center reactions and regulation of immune response and apoptosis. Our aim was to determine LTB gene expression in different hematologic neoplasias. DESIGN AND METHODS: We determined the expression of LTB using quantitative real-time reverse transcriptase polymerase chain reaction (RT-PCR) on a series of RNA samples from CD3(+) T cells and CD19(+) B cells isolated from peripheral blood (n=7); CD19(+) B cells isolated from lymph nodes (n=11) and from patients with acute lymphoblastic leukemia (ALL; n=16), acute myeloid leukemia (AML; n=43), chronic myeloid leukemia (CML; n=12), mantle cell lymphoma (MCL; n=19), chronic lymphocytic leukemia (CLL; n=32) and small lymphocytic lymphoma (SLL; n=22). RESULTS: The expression level of LTB in CD3(+) T cells and CD19(+) B cells isolated from blood was ten to forty times lower than that in normal CD19(+) B cells isolated from lymph nodes. In malignant myeloid cells the expression levels were very low, whereas in malignant lymphoid cells the expression was higher than in myeloid cells, being highest in MCL and CLL (20.2+/-14.0 ng/microL and 81.0+/-116.3 ng/microL) and low in SLL (4.5+/-3.6 ng/microL; p=0.001). We did not find correlations between LTB expression and hematoclinical parameters (risk groups, immunophenotypes and overall survival). INTERPRETATION AND CONCLUSIONS: A distinct difference in expression of LTB in CLL and SLL indicates that these morphologically similar B-cell malignancies are molecularly different. Further studies are needed to investigate the prognostic value of LTB and any role that LTB may have in determining whether the malignant B cells manifest a leukemia or lymphoma.

Megjegyzések:	Mantle cell lymphoma (MCL) is a non-Hodgkin's lymphoma of B-cell lineage. The blastoid variant of MCL, characterized by high mitotic rate, is clinically more aggressive than common MCL. We used the cDNA array technology to examine the gene expression profiles of both blastoid variant and common MCL. The data was analysed by regression analysis, principal component analysis and the naive Bayes' classifier. Eight genes were identified as differentially deregulated between the two groups. Oncogenes CMYC, BCL2 and PIM1 were upregulated more frequently in the blastoid variant than in common MCL. This implied that the gp130-mediated signal transducer and activator of transcription 3 (STAT3) signalling pathway was involved in the blastoid variant transformation of MCL. Other differentially deregulated genes were TOP1, CD23, CD45, CD70 and NFATC. By using the eight differentially deregulated genes, we created a classifier to distinguish the blastoid variant from common MCL with high accuracy. We also identified 18 genes that were deregulated in both groups. Among them, BCL1, CALLA/CD10 and GRN were suggested to be oncogenes. The products of RGS1, RGS2, ANX2 and CD44H were suggested to promote tumour metastasis. CD66D was suggested to be a tumour suppressor gene.
