Comparison of copy number variations between wildtype and BCL6 knockout BCR-ABL1-driven acute lymphoblastic leukemia

ABSTRACT: This comparative genomic hybridization (CGH) study investigated the effect of BCL6 on clonal evolution in BCR-ABL1-driven acute lymphoblastic leukemia (ALL). The frequencies of copy number alterations in BCR-ABL1-transformed BCL6+/+ and BCL6-/- leukemias were determined. Three BCR-ABL1-transformed BCL6+/+ and BCL6-/- ALL samples derived from mice were maintained for 4 month in cell culture and were subjected to CGH analysis. As control samples, normal untransformed splenoytes were used.

Gene expression data of BCR-ABL1 transformed B cell precursors from BCL6 wild-type and BCL6 knockout mice

Project description:To elucidate the mechanism of BCL6-mediated pre-B cell survival signaling, we investigated the gene expression pattern in BCR-ABL1-transformed BCL6+/+ and BCL6-/- B cell precursors. Pharmacological inhibition of BCR-ABL1 was performed with the BCR-ABL1 kinase inhibitor STI571 (Imatinib). BCR-ABL1 transformed B cell precursors of BCL6 wildtype and BCL6 knockout mice were either treated with 10ÂµM STI571 (Imatinib) for 16 hours or cultured in absence of STI571. Three samples for each condition were processed.

Effect of Bach2 overexpression in BCL6+/+ and -/- BCR-ABL1 transformed pre-B cells

Project description:The aim was to investigate how BCL6 genotype affects Bach2 dependent gene expression changes. We compared gene expression profiles of BCL6+/+ and BCL6-/- BCR-ABL1 transformed pre-B cells after inducible overexpression of Bach2.

Gene expression data of BCR-ABL1 transformed myeloid cells from BCL6 wild-type and BCL6 knockout mice treated with and without Imatinib and RI-BPI

Project description:To identify differences in the gene regulation between BCL6+/+ and BCL6-/- CML cells a gene expression analysis has been performed. We investigated the gene expression pattern in BCL6+/+ cells in the presence or absence of Imatinib and a combination of Imatinib and RI-BPI (a novel retro-inverso BCL6 peptide inhibitor). In BCL6-/- CML cells, we investigated the gene expression pattern in the presence or absence of Imatinib. BCR-ABL1 transformed myeloid cells from BCL6+/+ mice were cultured in the presence or absence of 10µM Imatinib or 10µM Imatinib and 20µM RI-BPI for 16 hours. BCR-ABL1 transformed myeloid cells from BCL6-/- mice were cultured in the presence or absence of 10µM Imatinib. Two samples for each condition were processed.

Recruitment of BCL6 to target genes in Philadelphia chromosome positive acute lymphoblastic leukemia

Project description:The Philadelphia chromosome (Ph) encodes the oncogenic BCR-ABL1 tyrosine kinase, which defines a subset of acute lymphoblastic leukemia (ALL) with a particularly unfavorable prognosis. Tyrosine kinase inhibitors (TKI) are widely used to treat patients with leukemia driven by BCR-ABL1 and other oncogenic tyrosine kinases. In response to TKI-treatment, BCR-ABL1 ALL cells upregulate BCL6 protein levels by ~90-fold, i.e. to similar levels as in diffuse large B cell lymphoma (DLBCL) with BCL6 translocations. In this study, we used genome tiling arrays to identify BCL6 target genes with specific recruitment of BCL6. Three Ph+ ALL cell lines (BV-173, NALM-1 and TOM-1) in duplicate were either treated with 10µM STI571 (Imatinib) for 24 hours or cultured in absence of STI571.

IKZF1 in BCR-ABL1 driven pre-B cells

Project description:In order to investigate the function of IKZF1 in ALL, we isolated bone marrow cells from C57Bl6 mice and transformed them with BCR-ABL1. In a second transduction the BCR-ABL1 driven pre-B cells were transformed either with IKZF1-GFP or empty vector control (GFP) and subjected to gene expression analysis.

Role and function of MYC in BCR-ABL1 driven pre-B cells

Project description:In order to investigate the function of MYC in ALL, we isolated bone marrow cells from conditional MYC knockout mice and transformed them with BCR-ABL1. In a second transduction the BCR-ABL1 driven pre-B cells were transformed either with CRE or empty vector control.
