Abstract：
:To discriminate with molecular-cytogenetic resolution between 3q26.2 breakpoint, associated to various myeloproliferative disorders, and 3q27 breakpoint, recurrent in several types of non-Hodgkin lymphoma, we tested the feasibility of using a yeast artificial chromosome, YAC clone H10, mapped on 3q26.3. Fluorescent in situ hybridization of the biotinylated polymerase chain reaction product of the YAC H10 was performed in three myeloproliferative diseases and one follicular non-Hodgkin lymphoma carrying different rearrangements of chromosome 3 involving region q26-q27. Our study shows that YAC H10 signal was telomeric to all three myeloid breakpoints, while it was centromeric in the lymphoid one thus showing that this probe can discriminate between these two subsets of chromosome 3 rearrangements. These results point out the opportunity of using additional YACs in the characterization of polymorphic chromosome alterations acquired in neoplastic cells.

LEUKEMIA文献大全abstract：:A relationship was proved between constitutive activity of leukemic cell c-jun-N-terminal kinase (JNK) and treatment failure in AML. Specifically, early treatment failure was predicted by the presence of constitutive JNK activity. The mechanistic origins of this association was sought. A multidrug resistant leukemic c...
