the aim of this study was to develop a novel multifunctional nanoparticle, which encapsulates spion and gemcitabine in plga±peg to form multifunctional drug delivery system. for this aim, super paramagnetic iron oxide nanoparticles (spions) were synthesized and encapsulated simultaneously with gemcitabine (gem) in plga±peg copolymers via w/o/w double emulsification method. optimum size and enca...
Objective (s): In chemotherapy for cancer treatment, the cell resistance to multiple anticancer drugs is the major clinical problem. In the present study, mesoporous silica nanoparticles (MSNs) were used as a carrier for epirubicin (EPI) in order to improve the cytotoxic efficacy of this drug against the P-glycoprotein (P-gp) overexpressing cell line. Materials and Methods: MSNs with phosphonat...
Background: The organochlorine DDT has estrogenic activity but the mechanism underlying the estrogenic activity of this pesticide remains unclear. In the present investigation here, we studied the transcriptional effects of a synthetic organochlorine pesticide o,p’-DDT [1.1.1.-trichloro-2-(o-chlorophenyl)-2-p-chloriphenyl ethane] and its metabolite p,p'-DDE (2-2-bis(4/chlorophenyl)-1-1-di...
Introduction: The use of drug delivery systems can increase the effectiveness of chemotherapy and reduce its side effects in the treatment of breast cancer. This study aimed to evaluate the effect of doxorubicin-containing silk fibroin nanoparticles (NF-DOX) on P53 gene expression in breast cancer cell lines and to measure its toxicity in vitro. Methods: NF-DOX was synthesized and characterize...
Background: ß-carbolines, harmaline and harmine, are the major alkaloids presenting in the seeds of the Peganum harmala L. These alkaloids are known as herbal active principals with potential use in pharmaceutical and medicine. Objectives: To assess the growth inhibitory effect of phyto-alkaloids, harmaline and harmine, on cancer cell lines. Method...
objective(s): acquisition of tnf-α resistance plays role in the onset and growth of malignant tumors. previous studies have demonstrated that mcf-7 cell line and its doxorubicin resistant variant mcf-7/adr are resistant against the cytotoxic effects of tnf-α. in this study, we investigated the role of akt activation in resistance of mcf-7 and mcf-7/adr against tnf-α cytotoxicity. materials and ...
Background & aim: Due to the presence of high amounts of compounds with antioxidant and cytotoxic properties in Foeniculum vulgare mill seed essential oil, the aim of this study was to investigate the toxicity of Foeniculum vulgare mill seed essential oil on MCF-7 breast cancer cell line and A2780 ovarian cancer cell line and to investigate the antioxidant activity of the essential oil of this ...
Several chalcones were synthesized and their in vitro cytotoxicity against various human cell lines, including human breast adenocarcinoma cell line MCF-7, human lung adenocarcinoma cell line A549, human prostate cancer cell line PC3, human adenocarcinoma cell line HT-29 (colorectal cancer) and human normal liver cell line WRL-68 was evaluated. Most of the compounds being active cytotoxic agent...
