Project description:In this study we compared the expression of 30215 genes in mantle cell lymphoma-initiating cells (MCL-ICs) with mantle cell lymphoma-non-initiating cells (MCL-non-ICs) and B-cells from healthy donor Three samples each of MCL-ICs and MCL-non-ICs were isolated from aphresis of 3 mantle cell lymphoma primary patient samples and 2 samples of CD19+ Bcells isolated from buffy coats of healthy donor Microarray include both coding and non-coding transcripts but only mRNA coding transcript were included in this study.

Project description:Mantle Cell Lymphoma (MCL) is a mostly incurable malignancy arising from naïve B cells (NBC) in the mantle zone of lymph node follicles. We analyzed genome-wide methylation in MCL patients using the HELP (Hpa II tiny fragment Enrichment by Ligation mediated PCR) assay and found significant aberrancy in promoter methylation patterns as compared to normal NBCs. Using biological and stringent statistical criteria, we further identified four hypermethylated genes CDKN2B, MLF-1, PCDH8, HOXD8 and four hypomethylated genes CD37, HDAC1, NOTCH1 and CDK5 where aberrant methylation was associated with inverse changes in mRNA levels. MassArray Epityper analysis confirmed the presence of differential methylation at the promoter region of these genes. Immunohistochemical analysis of an independent cohort of 14 MCL patient samples, confirmed CD37 surface expression in 93% of patients, validating its selection as a target for MCL therapy. Treatment of MCL cell lines with a novel small modular immunopharmaceutical(CD37-SMIP) resulted in significant loss of viability in cell lines with intense surface CD37 expression. Treatment of MCL cell lines with the DNA methyltransferase inhibitor decitabine resulted in reversal of aberrant hypermethylation and synergized with the HDAC inhibitor SAHA in induction of the four hypermethylated genes CDKN2B, MLF-1, PCDH8 and HOXD8. The combination of Decitabine and SAHA also resulted in potent and synergistic anti-MCL cytotoxicity as compared to either drug alone. In conclusion, our analysis shows prominent and aberrant methylation of the MCL genome and identifies novel differentially methylated and expressed genes in MCL cell lines and patient samples. Furthermore, our data suggest that differentially methylated genes can be targeted for therapeutic benefit in MCL. Gene expression profiling by array comprised of 8 mantle cell lymphoma (MCL) cell lines and 8 leukemic blast from blood from patients newly diagnosed with MCL. Unbiased genome-wide analysis of DNA methylation in leukemic blast from peripheral blood or pheresis products from 22 patients newly diagnosed with mantle cell lymphoma (MCL) prior to any treatment. 10 IgD+ Na ve B cells from specimens from healthy donors undergoing routine tonsillectomy were used as appropriate controls. Methylation patterns of 13 MCL cell lines were also compared.

Project description:Mantle cell lymphoma (MCL) is a B cell malignancy characterized by a monoclonal proliferation of lymphocytes with co-expression of CD5, CD43 but not CD23. Typical MCL are associated with cyclin D1 overexpression, and blastoid MCL variants are associated with c-myc translocations. We have developed a murine model of MCL-like lymphoma by crossing Cdk4R24C mice with c-myc-3’RR transgenic mice. Cdk4R24C mice is a knock-in strain that express a Cdk4 protein resistant to inhibition by p16INK4a and other INK4 family members. Breeding Cdk4R24C mice with c-myc-3’RR transgenic mice prone to develop aggressive Burkitt lymphoma-like lymphoma leads in c-myc/Cdk4R24C mice to development of clonal blastoid MCL-like lymphoma. A defect of the INK4-Cdk4 checkpoint can participate to lymphomagenesis in conjunction with additional alterations of cell cycle control, a situation which might be reminiscent of the development of human blastoid MCL. B splenocytes from 4 c-myc/Cdk4(R24C) lymphoma mice and 4 wt mice were investigated.

Project description:Mantle cell lymphoma (MCL) is a B cell malignancy characterized by a monoclonal proliferation of lymphocytes with co-expression of CD5, CD43 but not CD23. We have developed two murine models of MCL-like lymphoma. Breeding Cdk4R24C mice (a knock-in strain that express a Cdk4 protein resistant to inhibition by p16INK4a and other INK4 family members) with c-myc-3’RR transgenic mice (prone to develop aggressive Burkitt lymphoma-like lymphoma) leads in c-myc/Cdk4R24C mice to development of clonal blastoid MCL-like lymphoma. Breeding p53+/- mice with c-myc-3’RR transgenic mice lead to the development of several mature B cell lymphomas including MCL. In this study we compare MCL transcriptomas of c-myc-3'RR/Cdk4R24C mice and c-myc-3'RR/p53+/- mice. B splenocytes from 2 c-myc/Cdk4R24C lymphoma mice and 2 c-myc-3'RR/p53+/- mice were investigated
