Dysregulation of miR-224 has been shown to be involved in cancer tumorigenesis and progression of several cancer types. However, its expression patterns in tumors are controversial. The aim of this study was to determine the expression and clinical significance of miR-224 in pediatric acute myeloid leukemia (AML). Expression levels of miR-224 in bone marrow mononuclear cells were detected by re...
Thirty cases of newly diagnosed pediatric acute myeloblastic leukemia (AML) with French-American-British (FAB) M2 morphology were analyzed with cytogenetics and a comprehensive panel of monoclonal antibodies reactive with lymphoid-, natural killer (NK)-cell-, and myeloid-associated antigens. The t(8;21)(q22;q22), or t(8;21;V)(q22;q22;V), translocation was identified in 16 of the 30 cases. Cases...
Morphological pattern of 234 consecutive cases of various types of leukemias is presented. Acute leukemias (62.8%) were commoner than chronic (37.2%). Amongst acute leukemias, myeloid leukemias (AML) were more frequent as compared to lymphoblastic (ALL). AML:ALL ratio was 2.57:1 in adults and 1:3 in children. Amongst AML cases, M4 was the commonest, followed by M2, M1, M3 and M4 and M6 and M7 r...
Cytogenetic analysis of acute myeloid leukemia (AML) cells has accelerated the identification of genes important for AML pathogenesis. To complement cytogenetic studies and to identify genes altered in AML genomes, we performed genome-wide copy number analysis with paired normal and tumor DNA obtained from 86 adult patients with de novo AML using 1.85 million feature SNP arrays. Acquired copy n...
The plasma soluble interleukin-2 receptor (sIL-2R) level was higher in 137 patients with acute leukemia (1,489 +/- 1,798 U/ml, including 98 cases of acute myeloid leukemia (AML), 1,063 +/- 1,414 U/ml, and 39 cases of acute lymphoblastic leukemia (ALL), 2,561 +/- 2,194 U/ml), compared to 49 normal control subjects, 421 +/- 151 U/ml). The ALL patients showed elevated plasma sIL-2R levels more fre...
One case of acute panmyelosis with myelofibrosis (APMF) is here reported. A 45 year old male presented with abrupt onset of rapidly progressing low backache, weakness and pancytopenia. On examination there was no organomegaly. Peripheral blood examination revealed normocytic normochromic red blood cells with 10% circulating blasts. Flowcytometric examination of peripheral blood revealed blasts ...
OBJECTIVE Detection of chromosomal translocations has an important role in diagnosis and treatment of hematological disorders. We aimed to evaluate the 46 new cases of de novo acute myeloid leukemia (AML) patients for common translocations and to assess the effect of geographic and ethnic differences on their frequencies. MATERIALS AND METHODS In this descriptive study, reverse transcriptase-...
alpha- and beta-tryptase genes encode serine proteases that are abundantly expressed by mast cells. Under physiologic conditions other myeloid cells are virtually tryptase negative. However, tryptases are also expressed in several myeloid leukemia cell lines. In this study, serum total tryptase levels were determined in 150 patients with acute leukemias (de novo acute myeloid leukemia [AML], n ...
OBJECTIVE The aim was to determine relative frequencies of acute leukemia immunophenotypes using commonly expressed markers and to describe the clinicopathological characteristics. Design: This was a prospective cross-sectional study. SETTING The study was based at Aga khan clinical laboratory department. SUBJECTS One hundred and thirty two (132) consecutive blood and bone marrow specimens ...
