dc.description.abstract | Acute myeloid leukemia (AML) is a malignancy of hematopoetic tissue which occurs due to a halt in
differentiation, loss of proliferation control and dysregulated apoptosis of myeloid progenitor cells. In
many cancers, as well as AML, dysregulation of apoptosis constitutes the basis of pathogenesis and this
phenomenon is important for chemotherapy success. Pharmacotranscriptomic markers of AML
prognosis could be targets of specific therapy. The anti-apoptotic gene BCL2 (B-cell lymphoma protein
2), the pro-apoptotic BAX (BCL2-associated X) and genes involved in drug resistance, like MDR1
could have a significant impact on AML prognosis and therapy response. Bone-marrow samples at
diagnosis were collected from 51 adult patients with AML-NK. Expressions of BCL2, BAX and MDR1
were analysed using the real-time polymerase chain reaction method. Statistical evaluation was
performed. The presence of chemoresistance was found to be associated with overexpression of BCL2
(BCL2+) (p=0.018), while underexpression of BAX in patients has shown a greater affinity towards
relapse (p=0.034). Evaluating the expressions of BCL2 and BAX in a combined effect has shown that
87% of patients with BAX/BCL2low status were resistant to therapy (p=0.024). BCL2+ status was
associated with high expression of MDR1 (p<0.001). Likewise, high expression of MDR1 was
associated with the absence of NPM1 and FLT3-ITD mutations (p=0.048 and p=0.010, respectively).
This is the first study that focused only on AML-NK patients, when it comes to analysis of BCL2, BAX
and MDR1 gene expression profiles. The results of this preliminary study have shown that high BCL2
expression would likely lead to resistance from chemotherapy, making anti-BCL2 treatment a viable
option in patients with this expression profile. A study on a larger group of patients could clarify the
prognostic importance of the studied genes in adult AML-NK patients and improve the precision
medicine approach in the field of hematology. | sr |
