Abstract

Rumput mutiara merupakan tanaman yang berguna sebagai obat tradisional, tanaman ini termasuk kedalam famili tumbuhan Rubiaceae. digunakan sebagai obat alternatif penyebab penyakit infeksi yang disebabkan karena masuknya mikroorganisme kedalam tubuh. Salah satu mikroorganisme yang mengakibatkan penyakit ini adalah bakteri ( Amonim, 1993). Antibakteri adalah senyawa kimia yang dapat membunuh atau memghambat pertumbuhan mikroorganisme penyebab penyakit dengan kerusakan minimal jaringan induknya. Dilakukan penelitian aktivitas antibakteri dari ekstrak rumput mutiara (Hedyotis corimbosa (L.) Lamk) terhadap pertumbuhan beberapa bakteri, yang dlilakukan melalui 4 tahapan yaitu tahapan maserasi, tahapan ekstraksi fraksinasi, tahap pengujian fitokimia, dan diteruskan dengan tahap pengujian aktivitas antibakteri menggunakan metode difusi agar, parameter yang digunakan adalah dengan melihat zona terang yang dihasilkan (zona yang tidak terjadi pertumbuhan). Hasil penelitian menunjukkan bahwa dalam ekstrak rumput mutiara terdapat zat aktif yang berfungsi sebagai antibakteri yang terdapat dalam fraksi metilen klorida, pada fraksi ini aktivitas paling baik dihasilkan oleh bakteri S. Disentry dengan diameter daerah hambatan sebesar 27,5 mm.

Abstract

Apoptosis  is  an  important  target  on  anticancer  mechanism. The  purpose  of  this  research  is  to  investigate  apoptosis  induction of Selaginella plana Hieron active fractions on T47D cells. Absolute ethanol  was  used  to  extract Selaginella  plana powders.  Ethanolic extract  was  dilluted  by  methanol:water  (4:1)  and  then fractionated  by  hexane  (S_Hex),  methylene  chloride  (S_MTC), ethyl acetate (S_EA), and buthanol (S_BuOH). The proliferation of T47D  cell  line  was  detected  by  SRB  (Sulforhodamine  B) assay which  was  measured  at  a  wavelength  of  515nm.  Flowcytometry analysis  to  determine  apoptosis  was  examined  by  Propidium Iodide  (PI)  and  Annexin  V  assay  using  T47D  breast  cancer  cell line.  The  result  showed  that  the  IC50 value  of  S_Hex,  S_MTC, S_EA,  and  S_BuOH  on  T47D  cells  were  107  µg/mL,  4  µg/mL,  6 µg/mL,  and  17  µg/mL  respectively.  The  active  fractions  (S_MTC and  S_EA)  at  its  IC50 concentration  significantly  (P<0.05) increased  the  total  number  of  early  apoptotic  cells  in  the  T47D cells  3.39%  and  4.1%  respectively  compared  to  that  of  control (1.95%).  Based  on  the  result,  methylene  chloride  and  ethyl acetate  fraction  of Selaginella  plana induced  apoptosis  on  T47D cell.Keywords: apoptosis, breast cancer, Selaginella

Abstract

Brazilein performs anti­cancer activities on several cancer cells and potentially inhibits metastasis. The aims of this study is to observe the synergistic cytotoxic and migration inhibitory effect of brazilein combined with cisplatin on 4T1 breast cancer cells. Under MTT assay, we found that brazilein revealed cytotoxic effect on 4T1 cells in a dose­dependent manner (IC50=50 ± 0.3 µM). Combination of brazilein and cisplatin showed synergistic effect (CI=0.72). Flowcytometry analysis on the cell cycle progression showed that single treatment of 25 µM brazilein induced G2/M­phase accumulation, 12.5 µM cisplatin induced S­phase accumulation, while combination of brazilein and cisplatin induced S­phase and G2/Mphase accumulation. Combination of brazilein and cisplatin induced apoptosis higher than that of the single treatments. Based on wound healing assay, 12.5 µM brazilein and its combination with 6.25 µM cisplatin inhibited cells migration. Immunoblotting and gelatin zymography analysis showed that combination of brazilein and cisplatin inhibited the expression level of Rac1 and MMP9 proteins. Based on these results, we conclude that brazilein enhanced cytotoxic activity of cisplatin and inhibited migration on 4T1 cells and potentially can be developed as an enhancing cytotoxic and antimetastasis agent.

Abstract

Selaginella sp belongs to the Selaginellaceae family. It has been used in China and Indonesia as a traditional medicine. It hasseveral medicinal properties including antibacterial, anticardiovascular, and anticancer agent. The aim of the present study was to access the anticancer property of the ethanolic extracts of Selaginella plana Hieron. on T47D breast cancer cell line. The proliferation of T47D cell line was detected by SRB (Sulforhodamine B) assay which was measured at a wavelength of 515 nM. The result showed that the IC50 of the ethanolic extract was determined at 7.03 pg/mL. This significant activity was assumed due to its high total flavonoid content. The totalflavonoid content of the ethanolic extract was 23.04%. Flow cytometry analysis indicated that the extract may undergo the cell death via apoptosis pathway. In conclusion, the ethanolic extract of Selaginella plana Hieron: has considerable activity in inhibiting T47D cell line proliferation.Key words: Selaginella plana Hieron., SulforhodamineB, T47Dcells, anticancer flow cytometry
