Abstract

The aim of the present study was to investigate the effect of the essential oil of Javanese turmeric (Curcuma xanthorrhiza, Roxb) on level of low density lipoprotein-cholesterol (LDL-C) and body weight in rats. The groups were induced by high fat diet for 30 days to produce hyperlipidemia. The rats were treated with essential oil 25 mg/kgBW and simvastatin 25 kg/kgBW for 30 days. The LDL-C and body weight were measured on day one before treatment, and on day thirthy of the treatment. The results showed that the essential oil decreased the level of LDL-C and body weight in rats.Keywords: Javanese turmeric, Curcuma xanthorrhiza, essential oil, lipoprotein, simvastatin

Abstract

Watercress (Nasturtium officinale R. Br.) is an annual plant of the Brasicaceae family. Watercress has efficacy in the treatment of a hypo-allergenic, anti-diabetic, antioxidant, anticancer, and treatment of tuberculosis.The purpose of this research was to determine the potential for acute toxicity of ethanolic extract of watercress. This study aims to observe the histopathology liver , kidney , heart mice and to determine the LD50. Test animals used were 40 male mice and 40 female mice were divided into 8 groups. Group 1 as the control group were given Na – CMC 0,5 % b/v and groups 2-8 were given ethanol extract of watercress herb with a doses of  0,5; 5; 50 ; 500 ; 1000 ; 2000; and 4000 mg/kg bw . LD50 test is determined by the number of deaths in the test group during the 14 days of treatment in the form of one administration of the test materials. Histopathological results at the highest doses showed necrosis and hydropic degeneration of the liver, serosis the kidneys, and the heart inflammation with myofibril irregular heart. LD50 test demonstrated the practical test material is not toxic because no test animals died.Keywords: acute toxicity, Nasturtium officinale R. Br., Ethanolic extract

Abstract

Colon cancer is a malignancy in gastrointestinal tract. It causes high mortality rate in global cancer population. However, chemotherapy as its first option therapy is still controversial due to its effectiveness and its adverse effects. Finding supportive and alternative drugs to cure cancer is one of focus in cancer research. A drug which also has anticancer effects is metformin. Metformin is a biguanide antidiabetic which show its potential anticancer benefit in metabolic-related cancers including colon cancer. To investigate anticancer potency of metformin in targeting p53-related molecules. Metformin treatment were divided into 4 groups by 0, 5, 10 and 20 mM concentrations and incubated in 37o C and 5 % CO2 condition for 48 hours. Immunohistochemistry were conducted to asses level of expression of Bax, p21, cyclin D1 and E2F1, respectively. Level of expression were measured by H-SCORE using percentage and intensity calculation. Comparisons of H-SCORE between groups were performed by ANOVA for parametrical data and Kruskal-Wallis for non-parametrical data. Growth inhibition were observed after metformin treatment. Metformin increases Bax expression significantly at all concentrations. p21 expression was also increased after metformin treatment but is not statistically significant. Subsequently, metformin decreases cyclin D1 expression at 10 and 20 mM concentration thus decreased E2F1 expression at 5 and 10 mM concentration. These data suggest that metformin may have potential therapeutic effects in mutant p53 colon cancer cell line by targeting p53-related molecules.Keywords: Colon cancer; p53; Biguanide; Metformin; p53-mutant cell line

Abstract

Hedyotis corymbosa has been used for long time as an important component in several folklore medicine formula to clinically treat various types of cancer, including colorectal cancer (CRC). Previously, Hedyotis corymbosa ethanolic extract (HEE) which contain ursolic acid reported to inhibit CRC growth via induction of cancer cell apop­tosis and blocked the cell cycle, preventing G1 to S progression where cyclin D highly espressed in this phase. 5-fluorouracil (5FU), the first line chemotherapy of colorectal cancer have had resistence and possessed several side effects such as neutropenia, immunosuppression, diarrhea, and also constipation. Therefore, the aim of this research is to conduct the antiproliferative effect and molecular analysis of HEE and its combination with 5FU. Molecular docking study was also done to approach the specific protein target of the compound. Antiproliferative effect was conducted by MTT assay, while cyclin D expression  was examined by immunofluorescence. The proliferative effect showed that both HEE and 5-FU had cytotoxic effect with IC50 value of 65 µg/mL and 90 µM respectively, meanwhile the combination of HEE and 5FU have synergism effect with CI = 0.48 on dose HEE = 22 µg/mL and 5FU= 6.25 µM. Immunofluorescence assay showed HEE and its combination with 5FU suppressed the expression of cyclin D. From molecular docking simulation, ursolic acid performed stable interaction with cyclin D. Our findings suggest that HEE may be an effective treat­ment for co-chemotherapic for 5-FU through inhibition of cyclin D expression.Keywords : Hedyotis corymbosa, 5-fluorouracil, colorectal cancer,  WiDr, cyclin D

Abstract

Human Epidermal Growth Factor Receptor 2 (HER2) plays critical role in the initiation of breast cancer cell proliferation. Inhibition of HER2 overexpression is a promising strategy in the treatment of breast cancer. One of the potential natural substances that possess cytotoxic in cancer cells is Secang (Caesalpinia sappan L.). Ethanolic extract of secang heartwood containing brazilein and brazilin shows cytotoxic effect on various cancer cells. Thus this research aims to determine the proliferative inhibition activity of secang heartwood ethanolic extract (SEE) through HER2 expression on MCF-7/HER2 positive. Cytotoxic activity of SEE on MCF-7/HER2 positive cells was observed by MTT assay, meanwhile the inhibition activity of  HER2 on MCF-7/HER2 cells was determined by immunofluoresence assay. Furthermore, to confirm the possible mechanism of brazilein and brazilin for its cytotoxic activity was studied through molecular docking using PLANTS software. Based on this study, SEE exhibited cytotoxic effect on MCF-7/HER2 positive cells with IC50 value of 25 µg/ml, and EES also inhibited HER2 expression, indicated that the antiproliferative effect of SEE was possible through the inhibition of HER2. Docking score of brazilein, brazilin, and native ligand on HER2 were -77; -73; -120 respectively, showed the affinity of brazilein in HER2 was lower than affinity of native ligand, but they had specific amino acid to interaction. Hence, SEE can be developed as one of promising chemopreventive agent from natural products.Keywords: Caesalpinia sappan L., cytotoxic, immunofluorescence, molecular docking, MCF7/HER2 cells

Abstract

Cyclophosphamide (CPA) is an effective chemotherapeutic agent, but has side effect, causing DNA damage (genotoxic). Papaya leaf (Carica papaya L.) is known has flavonoid compound, quercetin. Quercetin is known has DNA protecting effect (antigenotoxic effect) by metabolism modulation. Thus, the aim of this research is to investigate the antigenotoxic effect of ethanolic extract of papaya (Carica papaya L.) leaf (EEPL) on CPA induced mice. The antigenotoxic effect was evaluated by mammalian in vivo micronucleus test. EEPL was orally administered as single treatment at dose 1000 mg/kgBW and in combination with CPA 50 mg/kgBW at dose 250 mg/kgBW; 500 mg/kgBW; and 1000 mg/kgBW. Molecular docking using PLANTS on CYP 3A4 was performed to explore the antigenotoxic effect mechanism. The three different combination dose of EEPL with CPA significantly (P<0.05) decreased the amount of micronucleated polychromatic erytrhocyte (MNPCE)/1000 polychromatic erythrocyte (PCE) and also increased % PCE/(PCE+normochromatic erythrocyte (NCE)), compared with single dose of CPA. Nevertheless, the antigenotoxic effect wasn’t significant compared with each combination dose. The docking score result showed quercetin (-82,41) has more potent interaction to CYP 3A4 than cyclophosphamide (-70,16) and both of them has similar active site at amino acid residue Ile 369 and Thr 309. The results obtained indicated that EEPL at dose 250 mg/KgBB is the optimal dose as antigenotoxic agent by interaction between quercetin with CYP 3A4 based on molecular docking.Keywords: antigenotoxic, Carica papaya L., MNPCE, in vivo
