introduction: in order to determine the multidrug resistance (mdr) phenotype due to p-glycoprotein expression in haematological malignancies including acute myeloblastic leukemia (aml), a well-characterized p-gp expressing cell line was required to validate and standardize flow cytometric assays and to calibrate instruments. therefore, this resistant subline of k562 was established for the firs...
مهار رشد رده سرطانی K562 با استفاده از کالپروتکتین (Calprotectin) نوترکیب انسانی در شرایط آزمایشگاهی
Background: Recombinant human Calprotectin is a protein that has inhibitory effect on the growth of cancer. This substance could use as a marker or therapeutic agents for cancer. The goal of this study was to evaluate the anti-tumor property of recombinant human Calprotectin on K562 cell line. Methods: Recombinant human Calprotectin was cloned and purified in E. coli. Then, different concent...
Background: RNA interference (RNAi) is the mechanism of gene silencing-mediated messenger RNA degradation by small interference RNA (siRNA), which becomes a powerful tool for in vivo research, especially in the areas of cancer. In this research, the potential use of an expression vector as a specific siRNA producing tool for silencing of Bcr-abl in K562 cell line has been investigated. Methods:...
Background and Aim: Chronic myelogenous leukemia is characterized by Philadelphia (Ph) chromosome, the presence of BCR-ABL fusion gene and constitutive activation of the ABL1 tyrosine kinase. Despite an excellent result of target therapy by imatinib, some patients develop resistance to imatinib. In this study Efficacy of HESA-A on proliferation and apoptosis of K562 cell line was assessed. Mat...
Objective(s): β-thalassemia is one of the most common genetic disorders in the world. As one of the promising treatment strategies, fetal hemoglobin (Hb F) can be induced. The present study was an attempt to reactivate the γ-globin gene by introducing a gene construct containing KLF1 binding sites to the K562 cell line. Materials and Methods: A plasmid containing a 192 bp sequence with two repe...
abstract the antineoplastic activities of alcoholic and aqueous extracts of the roots, stems and leaves of isatis campylocarpa an endemic species of the brassicaceae family from iran, investigated on the growth of jurkat as an acute lymphocytic leukemia cell line, k562 as a chronic myelogenous leukemia cell line and fen as a bladder cancer cell line using colorimetric assay. results showed that...
Introduction: Chronic myeloid leukemia (CML) is a malignant clonal disorder of hematopoietic stem cells resulting in the increase of myeloid cells, erythroid cells and platelets in the peripheral blood and hyperplasia in bone marrow. The research evaluated the cytotoxic effects of hydro-alcoholic extracts of Lepidium Sativum (Cress plant) shoots before and after flowering on K562 cell line as a...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
The K562 Chronic Myeloid Leukaemia Cell Line undergoes Apoptosis in Response to 4-chloro-5-iodo-7H-pyrrolo[2.3-d]pyrimidine
Background and Aim: Micro RNAs are a group of small non-coding RNAs which play an important role in multiple processes such as proliferation, differentiation, apoptosis, and cancer. Recent studies indicate that mir-210 is overexpressed into erythroid linage during the differentiation of hematopoietic precursor. The main goal of the present study is to investigate the influence of mir-210 on the...
