Abstract

Kronična mijeloična leukemija (KML) je mijeloproliferativni poremećaj, karakteriziran prisutnošću Philadelphia (Ph) kromosoma, koji je rezultat recipročne translokacije između kromosoma 9 i 22, t(9;22)(q34;q11). Molekularna posljedica ove translokacije je konstitutivno aktivni tirozin kinazni protein BCR-ABL1, koji uzrokuje KML fosforilacijom brojnih nizvodnih proteina uključenih u stanični rast i apoptozu. Smatra se da velika većina pacijenata (95%) s KML-om pokazuje prisutnost klasične... More translokacije t(9;22)(q34;q11), te da su varijantne translokacije prisutne u 5-10% pacijenata s KML-om. U tim slučajevima, u translokaciju su uključeni dodatni jedan ili više kromosoma, uz kromosome 9 i 22. Cilj rada je dokazati prisutnost varijantnih translokacija Ph kromosoma pomoću interfazne fluorescencijske hibridizacije in situ (I-FISH) u pacijenata s kroničnom mijeloičnom leukemijom pri dijagnozi, korištenjem probe LSI BCR/ABL Dual Color, Dual Fusion.

Abstract (english)

Chronic myeloid leukemia (CML) is a myeloproliferative disorder characterized by the presence of the Philadelphia (Ph) chromosome, which is the result of the reciprocal translocation between chromosome 9 i 22, t(9;22)(q34;q11). The molecular consequence of this translocation is constitutively active protein tyrosine kinase BCR-ABL1, which causes CML by phosphorylating numerous downstream proteins involved in cell growth and apoptosis. It is considered that the vast majority of patients... More with CML show classical t(9;22)(q34q11) translocation and that in 5-10% CML cases variant Ph translokations are present. In these cases, one or more additional chromosomes are added to 9 and 22 chromosomes in translocation. The aim of this paper is to detect variant Ph chromosome translocations by interphasic fluorescence hybridization in situ (I-FISH) in patients with chonic myeloid leukemia at diagnosis, using LSI BCR/ABL Dual Color, Dual Fusion probe.
