Sgc8c aptamers on a stiff polymer scaffold form multivalent inhibitor targeting acute lymphoblastic leukemia.

We describe a 40-year-old woman with a history of precursor T-cell acute lymphoblastic leukemia who developed an orbital mass associated with diffuse infiltration of the paranasal sinuses. The clinical and radiologic findings suggested an orbital abscess. Examination of orbital and ethmoid sinus biopsy specimens revealed relapse of precursor T-cell acute lymphoblastic leukemia. Although orbital...

AIMS AND BACKGROUND The SET gene is a target of chromosomal translocations in acute leukemia and encodes a widely expressed multifunctional phosphoprotein. It has been shown that SET is upregulated in BCR-ABL1-positive cell lines, patient-derived chronic myeloid leukemia CD34-positive cells, and some solid tumors. METHODS AND STUDY DESIGN We determined the expression level of SET in 59 pediat...

B-Lymphoblastic Leukemia (B-ALL) is the second most common acute leukemia in adults. Its clinical manifestations include leukocytosis or leukopenia, anemia, and thrombocytopenia with an overall poor prognosis elderly patients. If relapse occurs, it commonly involves bone marrow but can also involve Extramedullary (EM) sites such as brain, testis, liver, spleen lymph nodes. Isolated extramedulla...

the significance of immunophenotyping is growing day by day. it provides basic information in regard to classification and prognosis of acute leukemia which helps the management of patients. this study was conducted to identify cd markers in leukemic patients admitted to tabriz, in northwestern iran. immunophenotyping of 60 patients with acute leukemia was determined. patients with acute myelog...

background: this cross sectional comparative study was performed to compare the mean fluorescence intensity of cluster of differentiation 45 between healthy individuals and patients with acute lymphoblastic leukemia. patients and methods: thirty three healthy individuals (mean age 11 years) and 41 patients with b cell acute lymphoblastic leukemia (mean age 7 years) were enrolled in the study in...

FACTORS EFFECTIVE IN THE PROGNOSIS OF NEUTROPENIC FEVER CHILDREN WITH ACUTE LYMPHOBLASTIC LEUKEMIA

acute lymphoblastic leukemia(all) is due to early stage arrest of lymphoblast development. the translocation of philadelphia (ph) chromosome occurs as a result of the bcr-abl fusion gene, which constitutively produced activated tyrosine kinase. this gene fusion is an important indicator for prognosis in all and is associated with poor overall survival and remission duration. bcr-abl could inter...

BACKGROUND The translocation t(1;19)(q23;p13), which results in the TCF3-PBX1 chimeric gene, is one of the most frequent rearrangements observed in B cell acute lymphoblastic leukemia. It appears in both adult and pediatric patients with B cell acute lymphoblastic leukemia at an overall frequency of 3 to 5%. Most cases of pre-B cell acute lymphoblastic leukemia carrying the translocation t(1;19...

Oncoprotein E2a/Pbx1 is produced by the t(1;19) chromosomal translocation of human pre-B acute lymphoblastic leukemia. E2a/Pbx1 blocks differentiation of primary myeloid progenitors but, paradoxically, induces apoptosis in established pre-B-cell lines, and no transforming function of E2a/Pbx1 has been reported in cultured lymphoid progenitors. Here, we demonstrate that E2a/Pbx1 induces immortal...
