Abstract

Ursolic acid has been widely known to possess biological activity against numerous tumor cell lines. Previous studies revealed its cytotoxicity on several cancer cells  in vitro by either inducing apoptosis or cell cycle modulation. This  study was conducted to investigate ursolic  acid’s  cytotoxicity  solely  and  in  combination  with  a  chemotherapeutic  agent, doxorubicin,  on  MCF-7  breast  cancer  cells,  followed  by  observation  on  its  mechanism. Cytotoxicity of single and combinational treatment of ursolic acid and doxorubicin on MCF-7 breast cancer cells were conducted by using MTT assay. Single treatment was then evaluated by  determining  IC50  value,  while  combinational  treatment  was  evaluated  by  analyzing  cell viability  and  evaluating  combination  index  (CI).  To  explore  the  mechanism  underlying cytotoxic  effect  on  respected  cells,  further  analysis  on  cell  cycle  profile  of  single  and combinational treatment was conducted by flow cytometry. Twenty four hours treatment of ursolic  acid  inhibited  MCF-7 cells’ growth with  IC50  value  of  37  µM,  while  combinational treatment  showed  that  several  concentration  combinations  of  ursolic  acid  and  doxorubicin exhibited  synergism  of  cytotoxic  activity  on  MCF-7  cells,  giving  optimum  CI  value  of  0.54. Flow cytometric analysis showed that combinational treatment induced G2/M arrest in MCF-7  cells.  These  results  show  that  ursolic  acid  is  promising  to  be  developed  as  either  single chemopreventive  agent,  or  as doxorubicin’s co-chemotherapeutic  agent  in  breast  cancer treatment.  Observation  on  the  selectivity  as  part  of  safety  aspect  together  with  in silico,  in vitro, and in vivo study on its molecular mechanism should be conducted.Keywords: ursolic acid, doxorubicin,co-chemotherapeutic agent, breast cancer, cell cycle

Metode penelitian yang digunakan dalam penelitian ini adalah penelitian eksperimen. Metode eksperimen digunakan untuk mengetahui efektifitas penggunaan Media Pembelajaran dalam meningkatkan hasil belajar dan siswa di SMA Negeri 1 Sinjai. Desain eksperimen yang digunakan adalah Pre-Experimental. Adapun jenis desain yang digunakan oleh peneliti adalah One Group Pretest and One Group Posttest Design. Berdasarkan hasil analisis data menunjukkan bahwa nilai pretest lebih rendah dari nilai posttest. Ini memperlihatkan sebelum penggunaan Media Pembelajaran dalam proses belajar mengajar nilai rata-rata siswa hanya sebesar 57,13 yang berada dalam kategori cukup. Namun setelah memberikan perlakuan dengan menggunakan Media Pembelajran nilai rata-rata siswa pada posttest menjadi 78,01 yang berada pada kategori baik. Sehingga, terdapat peningkatan yaitu sebesar 36.54%. Hal ini membuktikan, penggunaan Media Pembelajaran pada mata pelajaran sosiologi effektif untuk meningkatkan hasil belajar siswa pada mata pelajaran sosiologi Kata Kunci: Media pembelajaran, hasil belajar, sosiologi, pre-eksperimental

To explore the mechanism underlying cytotoxic effect on respected cells, further analysis on cell cycle profile of single and combinational treatment was conducted by flow cytometry. Twenty four hours treatment of ursolic acid inhibited MCF-7 cells’ growth with IC50 value of 37 µM, while combinational treatment showed that several concentration combinations of ursolic acid and doxorubicin exhibited synergism of cytotoxic activity on MCF-7 cells, giving optimum CI value of 0.54. Flow cytometric analysis showed that combinational treatment induced G2/M arrest in MCF-7 cells. These results show that ursolic acid is promising to be developed as either single chemopreventive agent, or as doxorubicin’s co-chemotherapeutic agent in breast cancer treatment. Observation on the selectivity as part of safety aspect together with in silico, in vitro, and in vivo study on its molecular mechanism should be conducted.Keywords: ursolic acid, doxorubicin,co-chemotherapeutic agent, breast cancer, cell cycle

Abstract

Doxorubicin is a commonly used chemotherapeutic agent in patients with breast cancer. The risk of side effect using of doxorubicin  such as cardiomyopathy and congestive heart failure which can lead to death. One of the  approach to overcome overloaded use of doxorubicin is the combined use with a chemopreventive agent (cochemotherapy), including the leaf extract of marigolds (Cosmos caudatus Kunth.). This research aims to reviewing the effect of the methanol extract of leaves of marigolds on the cytotoxic activity of doxorubicin in modulating cell cycle and apoptosis of breast cancer cells T47D. Determination of the cytotoxic activity of methanol extract of leaves of marigolds and doxorubicin as well as a combination of both conducted by MTT assay. modulation surveillance of cell cycle and apoptosis induction is done by using flowcytometry and analyzed by FACS Calibur program. Cytotoxicity assay single treatment of the methanol extract of leaves of marigolds produce use values of IC50 504,840 μg/ml, whereas IC50 values doxorubicin is 141,055 nM. The synergistic effect was shown a combination of methanol extract leaves marigolds and doxorubicin at concentrations of 84,17 μg/ml -23,5 nM; 84,17 μg/ml -47 nM; 126,25 μg/ml -23,5 nM; 252,5 μg/ml -35,25 nM and 252,5 μg/ml -71 nM with a combination index value (CI) consecutively of 0,5; 0,6; 0,6; 0,6 and 0,6. Observations modulation of cell cycle and apoptosis induction combination of methanol extract leaves marigolds and doxorubicin at concentrations of 84,17 μg/ml -23,5 nM, said that a combination of the methanol extract of leaves of marigolds and doxorubicin to inhibit the proliferation of cells in G2 / M phase and able to induce apoptosis of breast cancer cells T47D.Keywords: methanol extract of leaves of marigolds, doxorubicin, flowcytometry, cell cycle, apoptosis.

Abstract

Ocimum basilicum L has proven to have in vitro cytotoxic activity against breast cancer cells. Pathways that cause cell death can involve one of the proteins, which is BCL-2. This study aims to determine the decrease of BCL-2 protein expressions in breast cancer cells (T47D and MCF-7) tat are treated with the ethanol extract of Ocimum basilicum L. Ocimum basilicum L. was extracted using the maceration method with 70% ethanol solvent. The concentration of ethanol extract of Ocimum basilicum L. used to see the expression of BCL-2 protein in T47D and MCF-7 cells was 199 µg/ml and 388 µg / mL. The observation of BCL-2 protein expression is using immunocytochemical methods of T47D and MCF-7 cancer cells. The results showed that the ethanol extract of Ocimum basilicum L could reduce BCL-2 protein expression in breast cancer cells (T47D and MCF-7) at concentrations of 199 µg/ml and 388 µg/ml, respectively.
