introduction: for thousands of years, plants have been used as the main source of drug worldwide. recently, it has been found out that the plant artemisia annua and especially its derivatives such as artemether have anticancer properties. methods: in this study, the anticancer effect of artemether on mcf-7 breast cancer cell line was examined. mtt assay was used to assess the viability of cance...
In this report, we investigated the role and regulation of forkhead box M1 (FOXM1) in breast cancer and epirubicin resistance. We generated epirubicin-resistant MCF-7 breast carcinoma (MCF-7-EPI) cells and found FOXM1 protein levels to be higher in MCF-7-EPI than in MCF-7 cells and that FOXM1 expression is downregulated by epirubicin in MCF-7 but not in MCF-7-EPI cells. We also established that...
In this report, we investigated the role and regulation of forkhead box M1 (FOXM1) in breast cancer and epirubicin resistance. We generated epirubicin-resistant MCF-7 breast carcinoma (MCF-7-EPI(R)) cells and found FOXM1 protein levels to be higher in MCF-7-EPI(R) than in MCF-7 cells and that FOXM1 expression is downregulated by epirubicin in MCF-7 but not in MCF-7-EPI(R) cells. We also establi...
Proline degradation by proline dehydrogenase/proline oxidase (PRODH/POX) contributes to apoptosis or autophagy. The identification of specific pathway of apoptosis/survival regulation is the aim of this study. We generated knocked-down PRODH/POX MCF-7 breast cancer cells (MCF-7shPRODH/POX). PRODH/POX silencing did not affect cell viability. However, it contributed to decrease in DNA and collage...
Cancer cells acquire anticancer drug resistance during chemotherapy, which aggravates cancer disease. MDR1 encoded from multidrug resistance gene 1 mainly causes multidrug resistance phenotypes of different cancer cells. In this study, we demonstrate that JNK1/2 activation by an extract from the root of Morus alba L. (White mulberry) reduces doxorubicin-resistant MCF-7/Dox cell viability by inh...
Objective(s): The significant contribution of nanoparticles to cancer treatment has attracted therapeutic attention. The present study aimed to evaluate the synergistic effects of 5-fluorouracil (5-FU) and zinc oxide nanoparticles (ZnO NPs) as multimodal drug delivery on human breast cancer MCF-7 cells.Materials and Methods: In this in-vitro study, the impact of 5-FU and ZnO NPs in the sin...
High matrix metalloproteinase 1 (MMP1) expression is associated with enhanced breast cancer growth and metastasis and also might predict poor prognosis. In this study, we further investigated the functional role of MMP1 and how it is upregulated in multi-drug resistant (MDR) breast cancer cells. By retrieving microarray data in GEO datasets and the survival data in the Kaplan Meier plotter, we ...
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...
A series of Adriamycin-resistant human breast MCF-7 and human colon DLD-1 cancer cell lines were established by stepwise selection. The concentration of Adriamycin required to inhibit cell proliferation by 50% (IC50) in the parent breast line (MCF-7), Adriamycin-resistant lines (MCF-Ad5 and MCF-Ad10), and a 5-fluorouracil (5-FU)-revertant line (MCF-R) was 0.005, 3.3, 6, and 4.9 microM, respecti...
A new group of 4-(Imidazolylmethyl) quinoline derivatives possessing a methylsulfonyl COX-2 pharmacophore at the para position of the C-2 phenyl ring were designed and synthesized as selective COX-2 inhibitors and in-vitro anti breast cancer agents. In-vitro COX-1 and COX-2 inhibition studies showed that all the compounds were potent and selective inhibitors of the COX-2 isozyme with IC50 value...
