The effect of miR-146a-dependent regulation of STAT1 on apoptosis in acute lymphoblastic leukemia (ALL) Jurkat cells was investigated. The miR-146a mimic and miR-146a inhibitor vectors were constructed in vitro, and experimental grouping was as follows: Control group (untreated Jurkat cells), empty vector group (Jurkat cells transfected with empty vector), agonist group (Jurkat cells transfecte...

Three distinct immature T-cell acute lymphoblastic leukemia entities have been described including cases that express an early T-cell precursor immunophenotype or expression profile, immature MEF2C-dysregulated T-cell acute lymphoblastic leukemia cluster cases based on gene expression analysis (immature cluster) and cases that retain non-rearranged TRG@ loci. Early T-cell precursor acute lympho...

The proteasome has been successfully targeted for the treatment of multiple myeloma and mantle cell lymphoma; however, in other hematologic malignancies, bortezomib has been less effective as a single agent. Here, we describe effects of NPI-0052, a novel proteasome inhibitor, in leukemia model systems. In cell lines, NPI-0052 inhibits all 3 proteolytic activities associated with the proteasome:...

MicroRNAs (miRs) play an important role in tumorogenesis and chemoresistance in lymphoid malignancies. Comparing with reactive hyperplasia, miR181a was overexpressed in 130 patients with T-cell leukemia/lymphoma, including acute T-cell lymphoblastic leukemia (n = 32), T-cell lymphoblastic lymphoma (n = 16), peripheral T-cell lymphoma, not otherwise specified (n = 45), anaplastic large cell lymp...

background: leukemia is a malignant proliferative disorder of the hematopoietic cells. the important role of angiogenesis in leukemia has been reported by several studies. matrix metalloproteinases (mmps) are a large group of endopeptidases which degredate the extracellular matrix and play an important role in angiogenesis. objective: the present study was conducted to evaluate the patterns of ...

abstract introduction connection of socioeconomic status measures (such as income and education and parental addiction) to childhood leukemia are likely to vary with place and time. the aim of this study was to assess the relation between socioeconomic status and childhood leukemia. materials and methods a case- control study conducted on 86 case of acute lymphoblastic leukemia age 0-14 years i...

Gallic acid is a polyhydroxyphenolic compound which can be found in various natural products. It is recognized to be an excellent free radical scavenger and has been shown to induce apoptosis in lung cancer and leukemia cells. No report has addressed whether gallic acid affects mouse leukemia cells in vivo. In this study, we examined the in vivo effects of gallic acid on leukemia WEHI-3 cells a...

Objective: Phenolic compounds have been considered inhibitors of various cancers. Material and Methods: In this study, caffeic acid and gallic acid were appraised for their possible effects on apoptotic genes expression in a breast cancer cell line in vitro. We also evaluated ligand interaction and ligand binding with estrogen receptor alpha by m...
