Abstract

The development of cancer treatment were initiated by the existence of human’s effort to treat by applying certain materials which is mostly part(s) or extracts of plants, which are now adapted as traditional herbal medicine. The discovery of new drugs was based on intuition and empirical evidence. Thus, high luck factor was involved in a successful treatment with unguaranteed reproducibility. One example of drug being developed through conventional drug development is Taxol. Taxol is an extremely complex natural product and requires a bunch of hard work with high level of serendipity to be discovered as antitumor agent. Recently, rapid development in human biology and technology allow a change in drug discovery strategy by minimizing the luck factor. Targeted therapy has been a very promising strategy of drug development research, especially in cancer treatment. Although cancer has been known as a disease with very complex cellular and histo-pathophysiology, the abundance of studies on proteins, such as receptors and hormones, as the hallmarks of cancer allows us to explore carcinogenesis suppression further based on molecular targeted therapy. Kinases, one type of protein involved in signal transduction regulating cell growth and differentiation, could be the proteins that are proposed to be inhibited in suppressing tumor growth. An interesting example of the drug being discovered based on molecular modeling is the discovery of lapatinib as anti- cancer with specific target on HER-2 and EGFR to overcome the resistance of cancer to Herceptin caused by elevated level of EGFR expression.Keywords : targeted therapy, cancer, translational drug development

Abstract

Leunca (Solanum nigrum L.) has been proven to possess anticancer activity on some type of cancer cells. In vitro study of solamargine found in the herb showed cytotoxic effect against several breast cancer cell lines, such as T47D and MDA-MB-31. Hence, further study on its potential as a co-chemotherapeutic agent needs to be conducted, in order to overcome resistance problem commonly found in cancer chemotherapy. This study aimed to examine the cytotoxic activity of leunca herb ethanolic extract (LEE) alone and its combination with doxorubicin. Single and combinational treatment of LEE and doxorubicin on T47D breast cancer cells were done, and their viability representing cytotoxicity were analyzed by using MTT assay to determine the IC50 value and combination index (CI) to evaluate the combinational effect. Twenty four hours-treatment of LEE alone gave cytotoxicity activity showing a dose-dependent manner with the IC50 of 47 µg/ml, while combinational treatment showed that 4 µg/ml LEE was found to be synergist with 4 nM doxorubicin on T47D cells, with the optimum CI value of 0.59. This result shows that Solanum nigrum L. is potential to be proposed as doxorubicin co-chemotherapeutic agent against breast cancer. Further study on its molecular mechanism needs to be conducted.Key words: Solanum nigrum, doxorubicin, synergist, breast cancer

Abstract

Doxorubicin is one of chemotherapeutic agent widely used in breast cancer treatment, but in high dose doxorubicin gives negative side effect, including vomit, nausea, immune suppression, and cardiac toxicity. This toxicity hopefully could be reduced by combination chemotherapy using natural herbs such as ciplukan herb. This research was conducted to explore cytotoxic activity of single ciplukan herbs ethanolic extract and its combination with doxorubicin on T47D breast cancer cells. Cytotoxic activity of ciplukan herbs ethanolic extract only and its combination with doxorubicin were tested on T47D cells using MTT assay to obtain IC50 value and combination index (CI), respectively. Single extract showed cytotoxic activity on T47D cells with IC50 value of was 160 µg/ml. Thus, combination treatment from ciplukan herbs ethanolic extract and doxorubicin showed synergistic effect (CI<1,0). This effect was reached at concentration of ciplukan herbs ethanolic extract-doxorubicin 80 μg/ml- 2 nM, 80 μg/ml-4 nM, and 80 μg/ml-8 nM. This research indicated that ciplukan herbs ethanolic extract is potential to be applied as co-chemotherapeutic agent in breast cancer therapy.Key word : ciplukan herbs, doxorubicin, co-chemotherapy, T47D cells

Abstract

Naringenin, an abundant flavanon in the peel of citrus fruits is reported to possess anti-proliferative effect in many cancer cells. Herein, we investigated the cytotoxic effect and apoptosis induction of naringenin in combination with doxorubicin on HeLa cells. The cytotoxicity assay of naringenin, doxorubicin, and their combination were carried out by using MTT assay. Cell viability was used as the parameters to evaluate combination effectiveness. Cell cycle distribution was determined by flow cytometry and analyzed using ModFit LT 3.0 program. Apoptosic assay was done by double staining method using Ethidium Bromide-Acridine Orange. Investigation on the expression of Bax and Bcl-2 were determined by immunocytochemistry method. Naringenin and doxorubicin showed cytotoxic effect on HeLa cells with their IC50 values of 195 µM and 1 µM, respectively. Whereas combination of naringenin - doxorubicin showed greater cytotoxicity compared the single treatment of doxorubicin. The strongest cytotoxic activity was observed at a combination of 100 µM naringenin and 0,5 µM doxorubicin. Single treatment of 0,5 µM doxorubicin for 24 hours on HeLa cells induced S-phase arrest while 100 µM naringenin did not affect on HeLa cell cycle. The combination induced S-phase arrest with the increased of sub-G1 phase percentage. In accordance with the flow cytometry results, the double staining apoptosis assay results showed the increase of apoptotic cells. Naringenin, doxorubicin, and their combination also increased the expression of Bax and decreased the expression of Bcl-2. These results concluded that naringenin was a potential co-chemotherapy agent for cervical cancer due to its synergism with doxorubicin.Keywords: co-chemotherapy, naringenin, doxorubicin, HeLa cells, cytotoxicity, cell cycle, apoptosis

Abstract

HER2‐positive breast cancer is an aggressive form of the disease that is associated with poor prognosis and chemo‐resistance. As such, investigation continues into the development of a new HER2‐targeted drug for breast cancer. This study investigated the anti‐proliferative activities of pentagamaboronon‐0‐sorbitol (PGB‐0‐So) in HER2‐overexpressing breast cancer (MCF‐7/HER2) cells. The cytotoxicity of PGB‐0‐So was assessed via MTT assay. Flow cytometry with propidium iodide and annexin‐V‐FITC staining was conducted to investigate the mechanism of PGB‐0‐So in inhibiting the proliferation of MCF‐7/HER2 cells. Finally, FACS analysis with 2′,7′–dichlorofluorescin diacetate staining was performed to examine intracellular ROS production. PGB‐0‐So exerted cytotoxicity towards MCF‐7/HER2 breast cancer cells with an IC50 value of 36 μM. PGB‐0‐So induced S‐phase arrest and apoptosis in MCF‐7/HER2 cells. Moreover, PGB‐0‐So could increase intracellular ROS production in MCF‐7/HER2 cells. PGB‐0‐So exerted anti‐proliferative activity towards MCF‐7/HER2 cells. This compound may be developed as a chemotherapeutic agent against HER2‐overexpressing breast cancer.
