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...

PURPOSE Arsenic trioxide (ATO) as a single agent is used for treatment of acute promyelocytic leukemia (APL) with minimal toxicity, but therapeutic effect of ATO in other types of malignancies has not been achieved. We tested whether a combination with ethacrynic acid (EA), a glutathione S-transferase P1-1 (GSTP1-1) inhibitor, and a reactive oxygen species (ROS) inducer will extend the therapeu...

BACKGROUND Arsenic trioxide (ATO) has been reported to have activity in vitro against multiple myeloma cells. Recently, it has also been used as a therapeutic agent to treat acute promyelocytic leukemia (APL) patients who have relapsed from conventional treatment with all-trans retinoic acid (ATRA) and chemotherapy. Recent studies from our laboratory indicate that ascorbic acid (AA) enhances th...

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 ...

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...

In the current study, we examined whether ligation of CB2 receptors would lead to induction of apoptosis in tumors of immune origin and whether CB2 agonist could be used to treat such cancers. Exposure of murine tumors EL-4, LSA, and P815 to delta-9-tetrahydrocannabinol (THC) in vitro led to a significant reduction in cell viability and an increase in apoptosis. Exposure of EL-4 tumor cells to ...

UNLABELLED Non-Hodgkin lymphomas incidence has increased more than 70% in last 25 years. Aggressiveness, higher relapse rate, and treatment complications pose significant barriers. Decreased food intake and side effects of treatments make cancer patients vulnerable to deficiency of essential nutrients such as vitamin C, lysine, and proline leading to the formation of weak extra cellular matrix ...
