C-myc-3'RR/p53+/- mice lymphomas

ABSTRACT: c-myc-3'RR mice prone to develop Burkitt lymphoma (BL) were crossed with p53+/- mice in order to obtain c-myc-3'RR/p53+/- mice. These mice develop a wider spectrum of lymphoma including BL, mantle cell lymphoma (MCL) and plasma cell lymphoma (PCL). Transcriptoma analysis of these lymphomas is investigated in these arrays.

c-myc-3'RR/p53+/- mice lymphomas

Project description:c-myc-3'RR mice prone to develop Burkitt lymphoma (BL) were crossed with p53+/- mice in order to obtain c-myc-3'RR/p53+/- mice. These mice develop a wider spectrum of lymphoma including BL, mantle cell lymphoma (MCL) and plasma cell lymphoma (PCL). Transcriptoma analysis of these lymphomas is investigated in these arrays. Four different plasma cell lymphoma (PCL1-4), three different mantle cell lymphoma (MCL1-4) and four different Burkitt lymphoma (BL1-4) were compared.

Transcriptoma comparison of mantle cell lymphoma of c-myc-3'RR/Cdk4R24C mice and c-myc-3'RR/p53+/- mice

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

The class-specific BCR tonic signal modulates lymphomagenesis in a transgenic model of c-myc transgene deregulation.

Project description:c-myc-3'RR mice developed Burkitt like lymphoma (IgM and IgD positive cells). We wished to study lymphomagenesis in mice carrying a modified B cell receptor with a higher level of tonic signal. The c-myc-3'RR transgene was introduced in a background with an IgH mutation that replaces IgM with IgA expression. Lymphoma arising in double mutant animals mostly carried the phenotype of activated cells, often expressing CD43, and in 10% of cases carrying a plasma cell phenotype. BCR tonic signal appears as a direct modulator of B cell malignancy phenotype. Burkitt lymphoma (BL) from 4 c-myc-3'RR mice, anaplastic (ANA) lymphoma from 4 c-myc-3'RR mice, CD43 negative lymphoma from 4 c-myc-IgA mice and CD43 positive lymphoma from 4 c-myc-IgA mice were investigated.

Transcriptoma analysis of B splenocytes of 3'RR-deficient mice and wt mice

Project description:The IgH 3' regulatory region (3'RR) controls class switch recombination and somatic hypermutation in mice. Similar numbers of B cells are found in spleen of 3'RR-deficient mice and wt mice. We compare their transcriptoma in order to find differences in their maturation status. B splenocytes from four wt mice and four 3'RR-deficient mice are investigated. Splenic B cells are purified with anti-B220-coupled beads.

A defect of the INK4-Cdk4 checkpoint and c-myc collaborate in blastoid mantle cell lymphoma (MCL)-like lymphoma formation in mice

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.
