Objective(s): This study focused on determining cytotoxic effects of copper oxide nanoparticles (CuO NPs) on chronic myeloid leukemia (CML) K562 cell line in a cell-specific manner and its possible mechanism of cell death. We investigated the cytotoxicity of CuO NPs against K562 cell line (cancerous cell) and peripheral blood mononuclear cell (normal cell). Materials and Methods: The toxicity w...
The expression of the beta-like globin genes is intricately regulated by a series of both general and tissue-restricted transcription factors. The hemapoietic lineage-specific transcription factor GATA-1 is important for erythroid differentiation and has been implicated in regulating the expression of the erythroid-specific genes including the genes of the beta-globin locus. In the human erythr...
Quantitation of target mRNAs using the reverse-transcription polymerase chain reaction found a widespread field of application in diverse biomedical diagnostic assays. However, the problem of varying sample quality has to be solved by correcting target molecule amounts through detection of an endogenous control template. The choice of an appropriate reference gene is still object of debate as p...
Cells of the proerythromyeloid cell line K562 and of the T cell line Jurkat were able to induce an increase in TNF-, IL1 alpha-, and IL1 beta-mRNA expression in human peripheral blood derived monocytes in vitro. The activating principle of these tumor cells was associated with fractions of membrane preparations of distinct molecular mass, 32-38 kD for Jurkat cells and 46-54 kD for K562 cells, r...
Among several prostaglandins (PGs) tested, PGF1 alpha was found to slightly enhance, while PGAs and PGDs were found to drastically inhibit the growth of K562 cells in culture. This effect was dose dependent. While PGD2 was cytotoxic, PGA1 treatment could totally inhibit K562 cell proliferation, without affecting cell viability. PGA1 action was reversible; however, K562 cells totally lost their ...
Apoptosis is a programmed cellular process that occurs in pathological and physiological pathways it one of the most studied topics cell biology. To understand underlying mechanism apoptosis plays an important role molecular pathogenesis many diseases including cancers. Chronic myeloid leukemia (CML) clonal myeloproliferative malignancy arising from neoplastic transformation hematopoietic stem ...
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:...
Recent studies indicate that a purified protein, activin A, belongs to the transforming growth factor beta (TGF-beta) superfamily. Similar to TGF-beta, activin A can have different biologic activities, depending on the target tissues. We used recombinant activin A to demonstrate a possible regulatory role of this protein in modulating human erythroid differentiation in the human erythroid cell ...

Background: Chronic myeloid leukemia is a common cancer in human, so the goal of this study was the use of natural compound such as cell wall obtained from Saccharomyces cerevisiae (S. cerevisiae) and Saccharomyces boulardi (S. boulardi) and zinc nanoparticles on the growth inhibition of K562 cell line. Methods: For cell wall preparation, both yeasts were cultured in a basic medium at a...
