Antiangiogenesis (inhibition of new blood vessels formation) has become a strategy to inhibit cancer development. The aim of this experiment was to investigate antiangiogenic effect  of  Gynura  procumbens  (Lour)  Merr  focusing  on  the  decreasing  of  the  number  of macrophages  and  heterophils  on  chick  embryo  chorioallantoic  membrane.  Nine-days-aged-eggs  were  divided  into  six  groups  (eight  eggs  each  group).  Group  I  (positive  control)  eggs were  induced  with  bFGF+Tris  HCl.  Group  II  (negative  control)  eggs  were  treated  with DMSO+Tris  HCl.  Group  III  (treatment  I)  eggs  were  induced  with  60  ng  bFGF  and  treated with  ethanolic  extract  of  G.  procumbens  leaves  with  the  dose  of  60  µg.  The  following treatment  groups,  i.e.  group  IV  (treatment  II),  group  V  (treatment  III),  and  group  VI (treatment IV) were treated with increasing dose of extract, starting from 75 µg, 90 µg, and the last was 110 µg. Eggs were incubated until they reach the age of twelve days to observe macrophages, while  to observe heterophils, eggs were incubated until  the  age of seventeen days. Based on haematoxylin-eosin staining, macrophages in the treatment groups were less than the control positive group (bFGF+Tris HCl), but based on giemsa staining, the effect of Gynura procumbens  in decreasing the number of heterophils could not  be observed  because some blood smears. These analysis suggest that  the  ethanolic extract of  Gynura procumbens leaves can perform as antiangiogenic agent decreasing the number of macrophages.Keywords: antiangiogenic, macrophages, heterophils, Gynura procumbens

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, GSTμ

BACKGROUNDMany tumors express on their receptor tyrosine kinases vascular endothelialgrowth factor activity associated with angiogenesis. Inhibition ofangiogenesis through reduction of tyrosine kinase activity is a promisingstrategy for cancer therapy. The present study aimed to determine themechanism and potency of ethyl p-methoxycinnamate (EPMC) isolatedfrom Kaempferia galanga as angiogenesis inhibitor.METHODSA laboratory experimental study was conducted using chorio-allantoicmembranes (CAMs) of nine-day old chicken eggs induced by 60ng basicfibroblast growth factor (bFGF). Ethyl p-methoxycinnamate (EPMC) potencywas determined at dosages of 30, 60, 90 and 120 μg and compared withcelecoxib 60 μg as reference drug and one negative bFGF-induced controlgroup. Neovascularization and endothelial cell count in CAM blood vesselswere evaluated. To predict the antiangiogenic mechanism of EPMC, adocking study was performed with the Molegro Virtual Docker program ontyrosine kinase as receptor (PDB 1XKK).RESULTSAngiogenesis stimulation by bFGF was prevented significantly (p<0.05)by EPMC at dosages of 30, 60, 90 and 120 μg and this activity was dosedependent. Molecular docking showed interaction between EPMC functionalgroups and tyrosine kinase amino acids at Met766, Met793, Thr854, Thr790,Gln791 and Ala743. There was an association between EPMCantiangiogenic activity and docking study results.CONCLUSIONSEthyl p-methoxycinnamate is a potential new angiogenesis inhibitor throughinteraction with tyrosine kinase. EPMC could be a promising therapeuticagent for treatment of angiogenesis-related diseases.
