Growth Arrest of BCR-ABL Positive Cells with a Sequence-Specific Polyamide-Chlorambucil Conjugate

Chronic myeloid leukemia (CML) is characterized by the presence of a constitutively active Abl kinase, which is the product of a chimeric BCR-ABL gene, caused by the genetic translocation known as the Philadelphia chromosome. Imatinib, a selective inhibitor of the Bcr-Abl tyrosine kinase, has significantly improved the clinical outcome of patients with CML. However, subsets of patients lose the...

BCR-ABL antisense oligodeoxyribonucleotides suppress the growth of leukemic and normal hematopoietic cells by a sequence-specific but nonantisense mechanism.

We have examined the effect of BCR/ABL junctional antisense phosphodiester oligodeoxyribonucleotides (ODNs) on BV173 and other chronic myeloid leukemia (CML) cell lines. Various control ODNs were used to understand the mechanism of the observed antiproliferative effect. Not only the antisense ODNs but also several control ODNs inhibit the proliferation of the leukemic cell lines. All the ODNs t...

In vivo eradication of human BCR/ABL-positive leukemia cells with an ABL kinase inhibitor.

BACKGROUND The leukemia cells of approximately 95% of patients with chronic myeloid leukemia and 30%-50% of adult patients with acute lymphoblastic leukemia express the Bcr/Abl oncoprotein, which is the product of a fusion gene created by a chromosomal translocation [(9:22) (q34;q11)]. This oncoprotein expresses a constitutive tyrosine kinase activity that is crucial for its cellular transformi...

DNA vaccination against bcr-abl-positive cells in mice.

A series of DNA vaccines based on the bcr-abl fusion gene were developed and tested in mice. Two mouse (BALB/c) bcr-abl-transformed cell lines, B210 and 12B1, which both expressed p210bcr-abl and were oncogenic for syngeneic animals but differed in some other respects, were used as a model system. In the first series of experiments, plasmids carrying either the complete bcr-abl fusion gene or a...

Induction of BCR-ABL-specific immunity following vaccination with chaperone-rich cell lysates derived from BCR-ABL+ tumor cells.

We have previously reported that chaperonerich cell lysates (CRCL) derived from the BCR-ABL+ 12B1 leukemia activate dendritic cells (DCs) and stimulate leukemia-specific immune responses. Because CRCL contain a variety of heat shock/chaperone proteins, we theorized that CRCL obtained from BCR-ABL+ leukemias are likely to chaperone BCR-ABL-derived fusion peptides and that DCs pulsed with 12B1 CR...
