Notch signaling, which is driven by the Notch1 receptor, plays an essential role in the pathogenesis and stroma-mediated drug resistance of T-cell acute lymphoblastic leukemia (T-ALL). However, little is known about the roles of Notch ligands in the survival or drug resistance of T-ALL cells. In the present study, isolated mesenchymal stem cells (MSCs) from human umbilical cord (hUC) samples, t...
BACKGROUND Despite the high cure rate of T cell acute lymphoblastic leukemia (T-ALL), drug resistance to chemotherapy remains a significant clinical problem. Bone marrow mesenchymal stem cells (MSCs) protect leukemic cells from chemotherapy, but the underlying mechanisms are poorly understood. In this study, we aimed to uncover the mechanism of MSC-induced chemoresistance in T-ALL cells, thus p...
objective(s): t-cell acute lymphoblastic leukemia (t-all) is an aggressive hematologic malignant tumor. administration of chemical compounds influencing apoptosis and t cell development has been discussed as promising novel therapeutic strategies. valproic acid (vpa) as a recently emerged anti-neoplastic histone deacetylase (hdac) inhibitor and pioglitazone (pgz) as a high-affinity peroxisome p...
Chronic lymphocytic leukemia (CLL) remains an incurable disease that requires innovative new approaches to improve therapeutic outcome. Many Ferula species, including F. asa-foetida, synthesize terpenyloxy coumarins. One of these coumarins is umbelliprenin, which has been implicated with induction of apoptosis in some cancer cell lines. In this study induction of apoptosis by umbellipre...
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...
Activation of host cell protein tyrosine phosphatases (PTPases) and protein dephosphorylation is an important mechanism used by various microorganisms to deactivate or kill host defense cells. To determine whether protein tyrosine dephosphorylation played a role in signaling pathways affecting Entamoeba histolytica-mediated host cell killing, we investigated the involvement of PTPases during th...
chronic lymphocytic leukaemia (cll) is the most common b-cell malignancy in the western world and exists as subtypes with very different clinical courses. myeloid cell leukemia 1 (mcl-1) is one member of bcl-2 family proteins that has been shown to be expressed in various tissues and malignant cells, including cll, where its expression is significantly associated with a failure to achieve compl...

 Purpose: To determine the effect of fresh soy milk and its compounds (coumestrol, daidzein genistein) on apoptosis in human leukemic cells peripheral blood mononuclear (PBMC).
 Methods: The apoptotic (K562, Jurkat, U937) PBMC was determined by flow cytometry. from healthy donors were isolated conducting density gradient centrifugation principle. Lymphoprep cytotoxicity evaluated 3-(...
