    The cytochrome P-450 (CYP) and glutathione S-transferase (GST) enzyme systems may influence the biological effects of carcinogens. As such, these enzymes may predict the developmental risk of breast cancer, as well as be potential targets for chemoprevention. The purpose of this study was to compare the expression of CYP1A1 and GST* between treatment groups. Expression of CYP1A1 and GST* was quantified in liver tissue from 18 female Sprague Dawley rats aged 40 days, which randomly divided into six treatment groups. Those are base line group (without DMBA and ethanolic extract treatment), DMBA induced cancer group, the other two groups was administrated by DMBA after treated by ethanolic extract in two different doses, 300 mg /kg BW and 750 mg/kg BW. The last two groups were given two doses of extract ethanolic only, without initiated of DMBA. The ingestion of the extract was carried for three weeks and the ingestion of DMBA was performed twice in the third week. The expression CYP1A1 and GST was quantified by immunohistochemistry. CYP1A1 expression was significantly higher (P < 0.05) in cancer group (DMBA) as compared with other groups. On the other hand, GST expression was lower in cancer group (P < 0.05). Result of this study demonstrated that ethanolic extract leaves of G. procumbens in 300 mg/kg BW dose could inhibit CYP1A1 stronger than are other and induced GST* level. Has effect on ethanolic extract leaves of G. procumbens has ability in played role of as blocking agent in preventing initiation stage of carsinogenesis, therefore it should be taken into account for chemopreventing agent in mammary carsinogenesis.Key words : Gynura procumbens, breast cancer, Chemopreventive, CYP1A1, GST

    Eurycomanone is a cytotoxic ingredient found in Eurycoma longifolia Jack. Previous studies have noted its activity against many epithelial cell lines. In this study, eurycomanone had obvious cytotoxic effect on HeLa cells by methylene blue staining assays. After HeLa cells were treated with eurycomanone, typical morphological changes, including cytoplasm shrinkage and decrease of cell volume were observed by light microscope. Chromatin condensation and nuclear fragmentation could be observed by fluorescence microscope after staining with Hoechst 33258 nuclear staining. DNA fragmentation and apoptotic body formation that is characteristic of apoptosis could be determined after treated cells were assayed with TUNEL (terminal deoxynucleotidyl transferase mediated d-UTP nick end labeling). The externalization of phosphatidyl serine (PS) could be determined by flow cytometry analysis using Annexin-V/PI double staining. The result suggested that eurycomanone exerted antiproliferative activity on HeLa cells by inducing apoptosis.Key words : eurycomanone, cytotoxic, apoptosis, HeL

    PGV-1 or 2,5-bis(4'-hydroxy-3',5'-dimethylbenzylidene)cyclopentanone and PGV-2 or 2,5-bis(4'-hydroxy-3',5' diethylbenzylidene)cyclopentanone are two benzylidene cyclopentanone analogues of curcumin. In our study, we investigated the effects of these compounds on the b-hexoaminidase enzyme release from mast cell culture (RBL-2H3 cell line). Thapsigargin and ionomycin were used as intracellular calcium ion stimulants for inducing b-hexoaminidase enzyme release from mast cells. The release of b-hexoaminidase enzyme was determined by colorimetric methods with substrate, p-nitrophenyl-2-acetamido-2-deoxy-b-D-glucopyranocide, and a microplate reader at 405 nm. In present study, treatment of 0.5 mM thapsigargin or 1 mM ionomycin could stimulate the release of b-hexoaminidase enzyme from RBL-2H3 cells by 43.91 ± 1.30 % and 52.93 ± 2.07 %, respectively. PGV-1 and PGV-2 showed inhibitory effects on the b-hexoaminidase enzyme release from RBL-2H3 cells induced by the increase of intraceluller calcium ion in dose dependent manner. At the dose of 100 mM, PGV-1 and PGV-2, respectively, inhibited the b-hexoaminidase enzyme release by 73.51 ± 8.69 % and 66.42 ± 8.63 % on thapsigargin experiments; and by 89.73 ± 3.23 % and 38.57 ± 5.32 % on ionomycin experiments. The IC50 values of their effects on the b-hexoaminidase enzyme release from RBL-2H3 cells, respectively, were 22.20 mM and 22.27 mM on thapsigargin experiment; and 22.77 mM and >100 mM on ionomycin experiment. Based on the results, the inhibitory effect of PGV-1 and PGV-2 on the b-hexoaminidase enzyme release from RBL-2H3 cells involving mechanisms related to the alteration on activation processes of intracellular calcium ion on mast cells.Key words : Curcumin, PGV-1, PGV-2, mast cells, b-hexoaminidase enzym
