Curcumin has been reported with an in vitro the cytotoxic effect on several human cancer cells. However, reports on the mode of action and detail mechanism of curcumin in breast cancer disease are limited. Hence, curcumin’s effect on the human breast cancer cell line MCF-7 and MDA-MB-468 was investigated. The MCF-7 and MDA-MB-468 breast cancer cells line were given curcumin in several doses. The anti-proliferation activity of curcumin was determined using the MTS cell viability test and caspase-3 activity was used to detect apoptosis using flowcytometry. The expression of Ras-association domain family 1 isoform A (RASSF1A) and Bax protein in cells was evaluated by ELISA analysis. Kruskal-Wallis followed by the Mann-Whitney test and the Spearman correlation tests were used to asses correlation among RASSF1A, Bax, and caspase-3. Cytotoxicity of curcumin on MCF-7 was lower than that of MDA-MB-468 (75.73 μg/mL and 380.79 μg/mL). The concentration of curcumin at 80 μg/mL induced apoptosis mainly through the intrinsic pathway by caspase-3 activation. Curcumin also showed an anti-proliferative activity as shown by the increase of RASSF1A and Bax protein. Curcumin mediates anti-proliferative and apoptotic effect through the activation of RASSF1A and Bax. Our research data adds information about the role of curcumin in epigenetic events through RASSF1A protein.Keywords: Bax, caspase-3, curcumin, MCF-7, MDA-MB-468, RASSF1A

Carbonated hydroxyapatite is frequently used as bone graft material in dentistry. It is highly biocompatible, has osteoconductive properties, and functions as a drug delivery system. Propolis is a natural product from bees that has antibacterial and anti-inflammatory effects and is capable of accelerating wound healing. Incorporating propolis into carbonated hydroxyapatite was expected to enhance the wound-healing process by stimulating fibroblast growth and regenerating alveolar bone in the treatment of periodontitis. The aim of this study was to evaluate the effect of carbonated hydroxyapatite with incorporated propolis on the viability of NIH 3T3 fibroblast cells. This study used three treatment groups [carbonated hydroxyapatite with various concentrations of incorporated propolis (5%, 7.5%, and 10%)] and one control group (carbonated hydroxyapatite with no propolis). An MTT assay was carried out to assess cell viability, and absorbance readings were performed by using an ELISA reader. The data were analyzed by using one-way ANOVA. The results showed significant differences between all groups, and carbonated hydroxyapatite with 10% incorporated propolis has the highest cell viability level of all groups, while the control group has the lowest cell viability. In conclusion, adding propolis to carbonated hydroxyapatite could increase the growth of NIH 3T3 fibroblast cells. Keywords: Carbonated hydroxyapatite, Propolis, NIH 3T3 fibroblast cells, MTT assay

Menopause is a hypoestrogenic condition due to decreased function of the ovary. During menopause there is no reserved ovum in the ovary, as a result the synthesis of estrogen by the follicles does not take place. Deficiency of estrogen can lead to discomfort and decrease in the women quality of life. Therefore, supplements from natural resources to reduce menopausal symptoms will be needed. The objectives of the study were to determine the effect of mahogany seeds ethanolic extract (MSEE) on the development of uterus, bone density, and mammae gland proliferation on ovariectomized rats. Extract was made by maceration using 96% ethanol as the solvent, then the study of estrogenic effect was carried out on 30 female rats which were divided into 6 groups. Group 1 (normal control), group 2 (positive control) given estradiol dose of 0.18 mg/kg body weight (BW), group 3 (negative control) given Na-CMC 1% and group 4, 5, 6 given MSEE orally for 14 consecutive days with doses of 50, 100, 200 mg/kg BW. Data were analysed using ANOVA then continued with Tukey HSD Post Hoc test to see the differences between the treatments. The results of the study showed that MSEE was able to increase the weight of the uterus, the length of estrus phase in the estrus cycle, bone density and the mammae gland proliferation of rats. The results concluded that MSEE has phytoestrogenic effect on ovariectomized rats.Keywords: phytoestrogen, ovariectomy, uterus weight, bone density, mammae proliferation

Flavonoid has potential bioactivity as anticancer agents. The flavonoid of cultivated tobacco (Nicotiana tabacum), locally known as “Kasturi”, leaves was screened for its cytotoxicity against MCF-7 human breast cancer cells and non-transformed Vero cells (African normal cell kidney line) in different concentrations. This study aimed to examine the cytotoxic potential of the flavonoid of Kasturi tobacco leaves against MCF-7 human breast cancer cells. Flavonoid obtained from methanolic extracts of Kasturi tobacco leaves, which have been purified from nicotine. The flavonoid of Kasturi tobacco leaves with concentrations of 20 to 640 μg/mL were exposed to MCF-7 and Vero cells for 24 h. Cell viability was evaluated by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. Flavonoid of Kasturi tobacco leaves with concentrations of 160 μg/mL decreased the MCF-7 cell viability more than 50%, with an inhibitory concentration 50 (IC50) value of 148.41 μg/mL. Meanwhile, it inhibited 50% of Vero cell viability at 255.35 μg/mL. The flavonoid of Kasturi tobacco leaves has cytotoxic activity on MCF-7 cells, and might be a potential alternative agent for human breast cancer therapy.Keywords: flavonoid, tobacco leaves, human breast cancer cells, anticancer activity

Cervical cancer is one of the most leading causes of women death. Currently, paclitaxel is still one of the main therapeutic regimens for cervical cancer patients. However, some patients developed to be paclitaxel-resistant. Hence, studies to find out the novel strategies to resolve this problem are important. Generating resistant cancer cell lines can be utilized as the potent tool to evaluate the efficacy of any therapeutic agent toward cancer drug-resistant problems. Current studies describing the methods to establish chemoresistance are lacking. Moreover, study in Indonesia conducting chemoresistance in cell line is limited. This study was aimed to elaborate the characteristics of HeLa cells during generation of paclitaxel-resistant cervical cancer cells. The parental HeLa cells were exposed to an escalating concentration of paclitaxel for a long time period. Subsequently, cells were divided into two groups for the evaluation of resistance characteristics. The values of inhibitory concentration 50 (IC50) and inhibitory concentration 90 (IC90) were analyzed using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay. Our data showed that the longer exposing periods of paclitaxel, the higher IC50 and IC90 values of HeLa cells are. IC90 of paclitaxel in HeLa Pac RB was increased from 69 pM, 440 pM, 2,561 pM and 10,337 pM on 0th, 1st, 2nd, 3rd and 4th months, respectively. Interestingly, the resistant cells were recovered to be paclitaxel-sensitive when they were not being continuously exposed to paclitaxel. In addition, the paclitaxel resistant cells become less sensitive against 5-FU but not doxorubicin, cisplatin and etoposide. We were able to generate cervical cancer HeLa paclitaxel-resistant cell line. These cell line could potentially be utilized for further studies in order to understand the molecular mechanisms of drug resistance in cervical cancer and as a tool for cancer drug discovery.Keywords: cervical cancer, drug resistant cell line, paclitaxel resistant cells, stepwise escalating concentration.

One of the main modalities of cancer treatment is chemotherapy, which uses chemicals that are generally electrophilic. These xenobiotic compounds sometimes does not produce effective response due to activity of glutathione S-transferase (GST) which inactivate the xenobiotics. Several natural phenolic compounds were reported to inhibit GST activity in vitro. Noni fruit (Morinda citrifolia L.) which contains flavonoids and other phenolic compounds such as scopoletin and morindon is proposed to interfere GST activity. This study aimed to analyze the effect of ethanolic extract of Noni fruit in vivo on GST activity in lung rat using 1,2-dichloro-4-nitrobenzene (DCNB). This substrate is a specific for class mu GST. First, rats were administered with ethanolic extract of Noni and dimethylbenz(α)anthracene (DMBA) for two weeks. The cytosolic fraction of lung was isolated then the GST activity was determined by simple kinetic program which was automatically calculated using spectrophotometer. The results showed that ethanolic extract of Noni in 1 and 5% (w/v) of concentration induced class mu GST activity, whereas 10% (w/v) of concentration inhibited class mu GST activity. After a treatment with DMBA, all tested concentrations of ethanolic extract of Noni inhibited class mu GST activity of lung rat significantly. These results indicated that Noni fruit extract can be further developed as a supportive agent of a chemotherapy drug.Keywords: DMBA, GST, Morinda citrifolia L., spectrophotometer.

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

TNBC, one of the sub type of breast cancers was widely known with high tumorigenic and poor prognosis than others. The development of combination agent (co-chemotherapy) with doxorubicin for chemotherapy of TNBC were carried out to decrease doxorubicin side effect and resistance in cancer. This present study aims to explore the co-chemotherapeutic properties of PGV-0 and investigate induction of doxorubicin on apoptosis, senescence and ROS against TNBC. 4T1 Cell line were used as a TNBC in vitro model. Cytotoxic measurement was performed using MTT assay resulting in IC50 values of 52 μM. Meanwhile, the combination of doxorubicin and PGV-0 showed synergistic effect which decreased cell viability of 4T1 better than single treatment of doxorubicin. Apoptosis analysis was performed using annexin V/PI assay indicated that the combination treatment of PGV-0 and doxorubicin increased apoptosis evidence. Senescence detection was carried out using senescence-associated-β galactosidase (SA-β-gal) assay. The results showed that a single treatment of PGV-0 induced cellular senescence and increased senescence cells in combination treatment. Moreover, DCFDA staining showed that PGV-0 increased ROS level at single treatment, whereas combination treatment increased ROS intracellular compared to the positive control of doxorubicin. Based on these results, PGV-0 has potential as a co-chemotherapeutic candidate on TNBC.Keyword: 4T1, PGV-0, Co-chemotherapy, Cytotoxic, Senescence, Apoptosis, ROS
