Osteosarcoma (OS) is the most common type of malignant bone tumor in children and adolescents. In total, 40-50% of patients with OS experience metastasis, and thus have a poor prognosis. Our previous study demonstrated that arsenic trioxide (As2O3) combined with doxorubicin [also known as Adriamycin (ADM)] significantly inhibited OS cell proliferation by downregulating stathmin expression. The ...
Arsenic (As) is a bioactive metalloid that highly toxic to humans, animals, and plants. Environmental contamination of As especially in groundwater increases due natural anthropogenic activities. The present study was performed evaluate the potential wild Tagetes species for phytoremediation contaminated soil/water. This comparative research aims analyze accumulation tolerance two Tagetes, T. m...
Although there is no compelling evidence that vitamin C has antitumor activity in humans, clinical trials are testing the hypothesis that ascorbic acid (AA) will enhance the efficacy of arsenic trioxide (As2O3) in myeloma. In vitro, AA cytotoxicity depends on its interaction with free transition metal ions in culture media leading to the generation of H2O2 and other reactive oxygen species (ROS...
The ameliorative effect of the aqueous extract of three medicinal plants P. fraternus. Terminalia A., and Moringa oleifera (PF, TA, and MO) on arsenic trioxide (As2O3) induced alteration in lipid peroxidation (LPO) and protein contents was studied in vitro. Liver from healthy chicken (Gallus domesticus) weighing 1.2 to 1.5 kg was bought to laboratory in frozen condition from local slaughter hou...
Arsenic trioxide (As2O3) has been introduced to the treatment of acute promyelocytic leukemia (APL), and has also been shown to induce apoptosis in a variety of solid tumor cell lines, including non-small cell lung cancer. However, the prohibitively high concentration required for the induction of apoptotic cell death in many solid tumor cells is unacceptable for clinical utilization due to the...
Cyclin-dependent kinase inhibitors CDKN2B and CDKN2A are tumor suppressor genes that are frequently dysregulated in a variety of cancers. Aberrant regulation via DNA hypermethylation causes gene silencing. Arsenic trioxide has been successfully used to treat malignant, hematopoietic diseases and is known to act by induction of apoptosis and inhibition of cellular proliferation. However, arsenic...
Although adoptive cell therapy (ACT) has demonstrated effective and remarkable clinical responses in several studies, this approach does not lead to objective clinical responses in all cases. The function of ACT is often compromised by various tumor escape mechanisms, including the accumulation of immunoregulatory cells. As a result of peritoneal metastasis in the terminal stage, malignant asci...
MRL/lpr mice develop a human-lupus-like syndrome and, as in autoimmune lymphoproliferative syndrome (ALPS), massive lymphoproliferation due to inactivation of Fas-mediated apoptosis. Presently, no effective therapy exists for ALPS, and long term, therapies for lupus are hazardous. We show herein that arsenic trioxide (As2O3) is able to achieve quasi-total regression of antibodyand cell-mediated...
Sphingosine kinase 1 (SphK1) is an important synthetase during the synthesis of sphingosine-1-phosphate (S1P) from sphingosine (Sph). Previous studies demonstrated that arsenic trioxide (As2O3) could reduce level S1P in human gastric cancer cell line MGC-803, indicating As2O3 may inhibit activity SphK1. In this study, effect on SphK1 activation pathway was investigated. Western blot and quantit...
سرم آلبومین انسانی (hsa) یک پروتئین اصلی برون سلولی با غلظت بالا در پلاسمای خون بوده و حامل بسیاری از داروها برای رسیدن به هدف های مولکولی متفاوت می باشد. سرم آلبومین انسانی با سایت های مناسب اتصال و ویژگی پیوندی بالا، یک عامل انتقال دهنده برای انتقال ترکیبات متعدد و داروها در داخل بدن می باشد . اتصال داروها به سطح hsa می تواند ویژگی های بیوفیزیکی و بیوشیمیایی این پروتئین را تغییر دهد. امروزه د...
