Nanocrystalline magnesium ferrites (MgFe2O4) were produced with an average grain size of about 20 nm. Their structural, morphological, and magnetic characterizations were studied. The cytotoxic effects of MgFe2O4nanoparticles in various concentrations (25, 50, 100, 200, 400, and 800 μg/mL) against MCF-7 human breast cancer cells were analyzed. MTT assay findings suggest the increased accumulation of apoptotic bodies with the increasing concentration of MgFe2O4nanoparticles in a dose-dependent manner. Flow cytometry analysis shows that MgFe2O4nanoparticles in 800 μg/mL concentration are more cytotoxic compared to vehicle-treated MCF-7 cells and suggests their potential utility as a drug carrier in the treatment of cancer.

Hyptis pectinata (L.) poit, popularly known in the world as “comb bushmint” is a medicinal plant commonly used for the treatment of throat and skin inflammations, bacterial infection, pain and cancer. The objective of this research is to determine the cytotoxic and antiproliferative effect under Hyptis pectinata ethanolic extract (HPE) treatment on breast cancer cells. The effect HPE of on cytotoxicity was examined by MTT assay on MCF-7 breast cancer cells. This assay also used to determine cell proliferation over 3 days of treatment with 1.5 – 100 µg/mL HPE. HPE showed that exhibited cytotoxic effects with IC50 value of 30 µg/mL for 24 hours and changes the physiological morphology on MCF-7 cells. Interestingly, the treatment of HPE for 48 and 72 hours highly decreases cell viability on MCF-7 with dose and time-dependent manner compared to untreated cells. These results indicate that HPE has antiproliferative activities and maybe the potential to be developed as a natural chemotherapeutic agent.Keywords: Hyptis pectinata (L.) poit extract, cytotoxicity, antiproliferative, MCF-7 cells

Curcumin is the active ingredient of Curcuma longa, which inhibits the development of malignant cells. Prevention and treatment of cancer by natural compounds, especially curcumin, and understanding the mechanism of action, is an area of interest in cancer research. In this study, we evaluated the effects of curcumin on cell proliferation, ornithine decarboxylase 1 (ODC1) and adenosine deaminase (ADA) gene expression in human breast cancer cell line (MCF-7) as compared to the non-cancer line (MCF-10A). Both cell lines were subjected to increasing doses of curcumin, ranging from 0 to 30 ?g/mL. Cell viability was quantified by the MTT assay. In vitro clonogenic survival assay was performed on MCF-7 cells. Expression of ADA and ODC1 were analyzed by Western blotting and qRT-PCR. Curcumin inhibited the growth of malignant cells in a time- and dose-dependent manner. The calculated IC50 value for MCF-7 cells in 48 h was 12 ?g/mL. Forty-five to 70% decreases in colony formation were observed in MCF-7 cells treated with 30-60 ?g/mL curcumin, respectively. Our data revealed a dose-dependent downregulation of ODC1 and ADA expression and respective enzyme activities by curcumin, which correlated with decreased proliferation in the MCF-7 breast cancer cell line. These data suggest that curcumin represses the proliferation of breast cancer cells through downregulation of ODC1 and ADA gene expression, which might be another mechanism of curcumin-mediated tumor growth inhibition.

Natural products have proved to be a promising source for the development of potential anticancer drugs. Emodin, a natural compound from Rheum palmatum, is used to treat several types of cancers, including lung, liver, and pancreatic. However, there are few reports regarding its use in the treatment of breast cancer. Thus, the therapeutic effect and mechanism of emodin on MCF-7 human breast cancer cells were investigated in this study. Morphological observations and cell viability were evaluated to determine the anti-proliferation activity of emodin. Network pharmacology and molecular docking were performed to screen the potential targets. Western blot analysis was used to explore a potential antitumor mechanism. The results showed that emodin (50–100 μmol/L) could significantly inhibit the proliferation of MCF-7 cells in a time and dose-dependent manner. Furthermore, virtual screening studies indicated that emodin was a potent aryl hydrocarbon receptor (AhR) agonist in chemotherapy for breast cancer. Finally, when MCF-7 cells were treated with emodin (100 μmol/L) for 24 h, the AhR and cytochrome P450 1A1 (CYP1A1) protein expression levels were significantly upregulated compared with the control group. Our study indicated that emodin exhibited promising antitumor activity in MCF-7 cells, likely through activation of the AhR-CYP1A1 signaling pathway. These findings lay a foundation for the application of emodin in breast cancer treatment.

Oridonin, a natural tetracycline diterpenoid isolated from Chinese herb Rabdosia rubescens, has been reported to be a potent cytotoxic agent against a wide variety of tumors. However, its effect on highly metastatic breast cancer cells has not been addressed. In this study, we investigated the effects of oridonin on growth, migration and invasion of highly-metastatic human breast cancer cells. Our results showed that oridonin induced potent growth inhibition on human breast cancer cells MCF-7 and MDA-MB-231 in a time- and dose-dependent manner. According to the flow cytometric analysis, oridonin suppressed MCF-7 cell growth by cell cycle arrest at the G2/M phase and caused accumulation of MDA-MB-231 cells in the Sub-G1 phase. The induced apoptotic effect of oridonin was further confirmed by a morphologic characteristics assay and TUNEL assay. Oridonin triggered the reduction of Bcl-2/Bax ratio, caspase-8, NF-κB (p65), IKKα, IKKβ, phospho-mTOR, and increased expression level of cleaved PARP, Fas and PPARγ in a time-dependent manner. Immunofluorescent analysis showed that γH2AX-containing nuclear foci were significant in oridonin-treated MDA-MB-231 cells. Meanwhile, oridonin significantly suppressed MDA-MB-231 cell migration and invasion, decreased MMP-2/MMP-9 activation and inhibited the expression of Integrin β1 and FAK. In conclusion, oridonin inhibited the growth and induced apoptosis in breast cancer cells, which might be related to DNA damage and activation of intrinsic or extrinsic apoptotic pathways. Moreover, oridonin also inhibited tumor invasion and metastasis in vitro possibly via decreasing the expression of MMPs and regulating the Integrin β1/FAK pathway in MDA-MB-231 cells.

Silver nanoparticles (AgNPs) have been used as an antimicrobial and disinfectant agents. However, there is limited information about antitumor potential. Therefore, this study focused on determining cytotoxic effects of AgNPs on MDA-MB-231 breast cancer cells and its mechanism of cell death. Herein, we developed a green method for synthesis of AgNPs using culture supernatant ofBacillus funiculus, and synthesized AgNPs were characterized by various analytical techniques such as UV-visible spectrophotometer, particle size analyzer, and transmission electron microscopy (TEM). The toxicity was evaluated using cell viability, metabolic activity, and oxidative stress. MDA-MB-231 breast cancer cells were treated with various concentrations of AgNPs (5 to 25 μg/mL) for 24 h. We found that AgNPs inhibited the growth in a dose-dependent manner using MTT assay. AgNPs showed dose-dependent cytotoxicity against MDA-MB-231 cells through activation of the lactate dehydrogenase (LDH), caspase-3, reactive oxygen species (ROS) generation, eventually leading to induction of apoptosis which was further confirmed through resulting nuclear fragmentation. The present results showed that AgNPs might be a potential alternative agent for human breast cancer therapy.

Phlogacanthus pulcherrimus T. Anderson (PPT) is an edible plant found in the northern and northeastern regions of Thailand. There is limited information about the anti-breast cancer activity of the ethanolic leaf extract of PPT. This study aimed to evaluate the effects of an ethanolic leaf extract of PPT on MCF-7 breast cancer cell lines. The biological effects, including cytotoxicity, cell apoptosis, colony formation, reactive oxygen species (ROS) formation and cell migration, were determined by a means of sulforhodamine B (SRB), acridine orange/ethidium bromide (AO/EB) staining, a clonogenic assay, flow cytometry and a scratch wound healing assay, respectively. The results demonstrated that the PPT extract showed cytotoxic on MCF-7 cells in a dose-dependent manner with 50% inhibitory concentration (IC50) values of 119.9 ± 12.1 and 51.3 ± 4.7 μg/mL at 24 h and 48 h incubation, respectively. In addition, the extract exhibited cell apoptosis in a dose-dependent manner when used at a concentration of 50–100 μg/mL and inhibited colony formation with an IC50 value of 26.0 ± 2.0 μg/mL when compared with the control group. The extract induced ROS formation in a dose-dependent manner when used at a concentration of 50–100 μg/mL. The extract suppressed MCF-7 cell migration, with significant effect at 25 μg/mL. These results indicate that PPT ethanolic leaf extract has an anticancer activity against MCF-7 breast cancer cells and may be useful for prevention and treatment of breast cancer.
