چکیده
Mutations of genes encoding isocitrate dehydrogenase (IDH1 and IDH2) have been recently described in acute myeloid leukemia (AML). Serum and myeloblast samples from patients with IDH-mutant AML contain high levels of the metabolite 2-hydroxyglutarate (2-HG), a product of the altered IDH protein. In this prospective study, we sought to determine whether 2-HG can potentially serve as a noninvasive biomarker of disease burden through serial measurements in patients receiving conventional therapy for newly diagnosed AML. Our data demonstrate that serum, urine, marrow aspirate, and myeloblast 2-HG levels are significantly higher in IDH-mutant patients, with a correlation between baseline serum and urine 2-HG levels. Serum and urine 2-HG, along with IDH1/2-mutant allele burden in marrow, decreased with response to treatment. 2-HG decrease was more rapid with induction chemotherapy compared with DNA-methyltransferase inhibitor therapy. Our data suggest that serum or urine 2-HG may serve as noninvasive biomarkers of disease activity for IDH-mutant AML.

The evaluation of TLR1, TLR2, TLR4, TLR7, and TLR8 expression levels in the newly-diagnosed acute myeloid leukemia (AML) patients
Background: Acute myeloid leukemia (AML) is described by the clonal expansion of myeloid blasts with abnormal differentiation. Considering the role of Toll-like receptors (TLRs) in inflammation induction and the effect of chronic inflammation on cancer development, investigating the state of TLRs’ expression in human malignancies has attracted scientists’ attention. Methods: In this study, 36 ...

Background: Acute myeloid leukemia (AML) is known as one of the most common leukemia among adults. Environmental and different genetic factors affect disease process, prognosis and treatment. Among different genetic factors NPM1, FLT3, MLL and BAALC genes are the most effective on patient's survival rate. The aim of this study was to assess amount of BAALC gene expression in AML patients, and i...

Background: Imatinib mesylate is the first generation of Tyrosine kinase inhibitors (TKI) and highly effective in the treatment of chronic myeloid leukemia (CML). We aimed to evaluate thyroid function at baseline and at 1, 3, 6 and 12 months after initiation of Imatinib mesylate therapy in 20 newly diagnosed BCR-ABL positive CML patients. Methods: This study was done during 2013-2014, 20 new c...

Acute myeloid leukemia (AML) is a type of poor prognosis hematological malignancies characterized by heterogeneous clonal expansion of myeloid progenitors. Leukemic stem cells are thought to form the majority of a cell population in minimal residual diseases (MRDs) which are resistant to current chemotherapeutic regimens and mediate disease relapse. Current therapeutic vaccine strategies have d...
