JAK2 inhibition in Philadelphia chromosome like acute lymphoblastic leukemia

Project description:CRLF2 rearranged Ph-like ALL cells are driven by oncogenic cytokine receptor signaling mediated by CRLF2 and JAK2. MHH-cALL4 cells were treated with ruxolotinib (JAK2 inhibitor) to provide insight into mechanisms of drug resistance.

Effect of imatinib on 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. In this study, the tyrosine kinase inhibitor imatinib was used for pharmacological inhibition of BCR-ABL1. Gene expression profiles of Ph+ ALL cell lines were analyzed in response to imatinib treatment.

Inhibition of BCL6-dependent gene expression 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 analyzed the gene expression changes after treatment with Imatinib or Imatinib + RI-BPI.

Effect of imatinib on 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. In this study, the tyrosine kinase inhibitor imatinib was used for pharmacological inhibition of BCR-ABL1. Gene expression profiles of Ph+ ALL cell lines were analyzed in response to imatinib treatment. Four Ph+ ALL cell lines (BV-173, NALM-1, SUP-B15, and TOM1) were either treated with 10µM STI571 (Imatinib) for 16 hours or cultured in absence of STI571.

In this study, we analyzed the gene expression changes after treatment with Imatinib or Imatinib + RI-BPI. Three Ph+ ALL cell lines (BV-173, SUP-B15 and TOM-1) were treated in the presence or absence of 10 μM STI571 (Imatinib) or in the presence of both 10 μM STI571 and 20 μM RI-BPI for 24 hours.

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.

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.
