acute lymphoblastic leukemia (all) is one of the most common cancers among children. although there have been tremendous treatments, none of them have led to a precise cure. the use of herbal medicines which are safe and non-toxic have been demonstrated in this study. curcumin is a polyphenol, hydrophobic product that is derived from turmeric plant. curcumin has anti-toxic, anti-bacterial, anti...

We report the anti-leukemic potency of a unique biotargeted nanoscale liposomal nanoparticle (LNP) formulation of the spleen tyrosine kinase (SYK) P-site inhibitor C61. C61-loaded LNP were decorated with a murine CD19-specific monoclonal antibody directed against radiation-resistant CD19-receptor positive aggressive B-precursor acute lymphoblastic leukemia (ALL) cells. The biotargeted C61-LNP w...

Ferroptosis is a newly defined programmed cell death (PCD) process with the hallmark of accumulation iron-dependent lipid peroxidation, which more immunogenic over apoptosis. shows great potential as therapeutic target against acute kidney injury (AKI), cancers, cardiovascular diseases, neurodegenerative and hepatic diseases. Accumulating evidence has highlighted that ferroptosis plays an unneg...

Two models have been proposed for the molecular mechanism by which the Tal1 oncogene causes T cell acute lymphoblastic leukemia (T-ALL). The activation model suggests that Tal1 as heterodimers with the E2A transcription factor activates the expression of oncogenes. The inhibition model postulates that Tal1 interferes with the tumor-suppressing function of E2A. In the Jurkat T cell line, origina...

Chemotherapy and radiotherapy are often used to treat Acute Lymphoblastic Leukemia (ALL). However, the resistance problem of treatment using current drug in ALL patients has decreased effectiveness such therapy. Therefore, a study needs be conducted identify potential new anticancer agents. Organotin (IV) dithiocarbamate, an organometallic compound, causes toxic effects on cancer cells vitro vi...

We have previously demonstrated that human gingival fibroblasts rescue butyric acid-induced T-cell apoptosis via proinflammatory cytokines such as interleukin 6 (IL-6) and IL-11, which are produced by fibroblasts stimulated with butyric acid. In this study, we determined if T-cell adhesion to human gingival fibroblasts influenced the susceptibility of T cells to butyric acid-induced apoptosis. ...

BACKGROUND Human T-acute lymphoblastic leukemia (T-ALL) Jurkat cells are often used for in vitro screening of anticancer compounds; however, in vivo models employing Jurkat cells have not yet been sufficiently described. In this report, the growth characteristics and histology of tumor masses developed following subcutaneous (s.c.) implantation of Jurkat cells into nude mice are presented. MA...

Background and Objective: Vascular endothelial growth factor (VEGF) is a cytokine which is overexpressed in many malignant cancers including leukemia. VEGF plays an important role in tumor invasion and metastasis. Determination of the pattern of VEGF expression in human leukemic cell lines could be useful not only in screening of new antileukemic agents but also to study the mechanism of their ...

We have recently reported that methionine adenosyltransferase (MAT) in resting human peripheral blood T-cells is primarily present in the form of a precursor which we named lambda. This protein decreases upon cell stimulation, as both MAT activity and the amount of the catalytic alpha/alpha' subunits of the enzyme increase. When resting cells are activated by phytohemagglutinin, the decrease in...

BACKGROUND AND OBJECTIVES The apoptotic Bcl-2 family member Hrk is transcriptionally silenced via DREAM in hematopoietic progenitor cell lines, and is specifically induced after growth factor withdrawal. Given that expression of Hrk is sufficient to induce apoptosis, we studied the expression of this apoptotic protein and its regulatory mechanism in human leukemia cells. DESIGN AND METHODS K5...
