Abstract

Eugenia uniflora Lam. is one of herbal products developed for anticancer. The aim of the present study was to identify the antiproliferative effect of ethanolic extract of Eugenia Uniflora Lam. leaves (EEU) on breast cancer cell line T47D. This Research was initiated by extracting the active contents of Eugenia uniflora Lam. leaves by maceration with ethanol 96%. The extract was then analyzed by thin layer chromatography (TLC). Cytotoxic assay of EEU was carried out by using MTT assay. Apoptosis phenomenon was observed with double staining using acridine orange-ethidium bromide. EEU showed cytotoxic effect on T47D cells with IC50 value of 65 µg/ml. Moreover, EEU 50µg/ml and 100µg/ml induced apoptosis. TLC examination showed that EEU used in this study contain phenolic, flavonoid, and saponin compounds which were suggested to be responsible for antiproliferative effect. Further molecular mechanism underlying EEU antiproliferative effect needs to be done.Keywords: Eugenia uniflora Lam., T47D cells, antiproliferative, apoptosis

The  prognosis  of  breast  cancer  patients  is  closely  associated  with  the  response  of tumor  cells  to  chemotherapy  agent.  Doxorubicin  is  one  of  the  primary  chemotherapeutic agents  used  for  the  treatment  of  breast  cancer.  Resistance  to  chemotherapy  is  believed  to cause  treatment  failure  in  cancer  patients.  Furthermore,  long  time  exposure  to chemotherapeutic  agent  induces  cancer  cells  resistance.  MCF-7  sensitive  cells  used  as chemoresistance  model  have  overexpression  P-gp  (P-glycoprotein).  Chemoresistance  was established by treating MCF-7 cells with 0.5 µg/ml doxorubicin-contained medium for a week. 50% inhibiting concentration (IC50) doxorubicin on MCF-7 cells/DOX were determined using MTT assay. Western blot assay and immunocytochemistry assay was performed to determine the expression of P-gp. Morphological of MCF-7 cell/DOX was changing to become larger and have  lamellapodia.  IC50  value  of  doxorubicin  was  700  nM  on  MCF-7/DOX  and  400  nM  on sensitive MCF-7 cells. The MCF-7/DOX sensitivity to doxorubicin was decreased, shown by 1.5  fold  higher  IC50  of  doxorubicin  on  MCF-7/DOX  compared  to  MCF-7  sensitive  cells. Treatment doxorubicin to sensitive MCF-7 cells leads to the increasing P-gp expression. The P-gp  level  expression  has  strong  correlation  with  the  low  sensitivity  of  MCF-7/DOX  to doxorubicin.Key words: doxorubicin, resistance cells, sensitive MCF-7 cell

Abstract

Kanker leher Rahim merupakan salah satu kanker yang paling terjadi pada wanita. Angka kematian yang tinggi menunjukkan bahwa kemoterapi tidak memberikan hasil yang baik sehingga perlu dikembangkan strategi untuk mengatasinya. Daun alpukat (Persea americana Mill) adalah salah satu produk alami yang memiliki aktivitas antioksidan dengan menangkap radikal bebas dan memiliki aktivitas sitotoksik. Tujuan dari penelitian ini adalah untuk mengevaluasi aktivitas sitotoksik dari ekstrak etanolik daun alpukat pada sel kanker leher Rahim HeLa dan mengidentifikasi senyawa aktif  yang ada pada daun alpukat. Senyawa aktif dari daun alpukat diekstraksi dengan metode maserasi menggunakan etanol 96%. Uji kromatografi dilakukan untuk mengidentifikasi senyawa aktif. Aktivitas sitotosik ekstrak etanolik daun alpukat dilakukan dengan uji MTT. Hasil skrining fitokimia menunjukkan bahwa daun alpukat mengandung senyawa golongan flavonoid, alkaloid dan saponin. Ekstrak etanol daun alpukat menghambat pertumbuhan sel HeLa dengan nilai IC50 sebesar360 µg/ml.

Abstract

Fraksi kloroform daun pandan (Pandanus amaryllifolius) diketahui memiliki efek sinergis sebagai kokemoterapi doksorubisin pada sel kanker payudara MCF-7 dan T47D. Penelitian ini untuk mengetahui efek toksik subkrosis fraksi kloroform daun pandan dikombinasi dengan doksorubisin. Penelitian dilakukan dengan menggunakan tikus Sprague Dawly 1-2 bulan sebanyak 40 ekor dibagi dalam 8 kelompok yang terdiri dari kelompok sehat, kelompok pelarut, kelompok doksorubisin, dan empat kelompok perlakuan kombinasi doksorubisin dan fraksi kloroform. Setelah 30 hari dilakukan pemeriksaan biokimiawi darah  trigliseride, LDL, HDL dan kolesterol. Hasil penelitian menunjukkan kombinasi doksorubisin dengan fraksi kloroform daun pandan tidak menyebabkan toksisitas terhadap jantung dan mampu menurunkan efek toksik doksorubisin terhadap jantung.

The prognosis of breast cancer patients is closely associated with the response of tumor cells to chemotherapy agent. Doxorubicin is one of the primary chemotherapeutic agents used for the treatment of breast cancer. Resistance to chemotherapy is believed to cause treatment failure in cancer patients. Furthermore, long time exposure to chemotherapeutic agent induces cancer cells resistance. MCF-7 sensitive cells used as chemoresistance model have overexpression P-gp (P-glycoprotein). Chemoresistance was established by treating MCF-7 cells with 0.5 µg/ml doxorubicin-contained medium for a week. 50% inhibiting concentration (IC50) doxorubicin on MCF-7 cells/DOX were determined using MTT assay. Western blot assay and immunocytochemistry assay was performed to determine the expression of P-gp. Morphological of MCF-7 cell/DOX was changing to become larger and have lamellapodia. IC50 value of doxorubicin was 700 nM on MCF-7/DOX and 400 nM on sensitive MCF-7 cells. The MCF-7/DOX sensitivity to doxorubicin was decreased, shown by 1.5 fold higher IC50 of doxorubicin on MCF-7/DOX compared to MCF-7 sensitive cells. Treatment doxorubicin to sensitive MCF-7 cells leads to the increasing P-gp expression. The P-gp level expression has strong correlation with the low sensitivity of MCF-7/DOX to doxorubicin.Keywords: doxorubicin, resistance cells, sensitive MCF-7 cell

Abstract

Colon cancer is one of the most common death-caused cancer. The high mortality rate indicates that chemotherapy has not overcome cancer disease. Strategies and development of colon cancer treatment should be pursued. Compound 1-(2,5-dihydroxyphenyl)-3-pyridine-2-yl-propenone is the 2ʹ,5ʹ-dihydroxychalcone derivative, of which the B ring was substituted with 2-pyridine ring. Chalcone and its derivatives have been reported to have several biological activities, such as cytotoxic, anti-inflammatory, antiHIV, and as a tyrosine kinase inhibitor. The objectives of this research was to determine the cytotoxic activity on WiDr colon cancer cells of 1-(2,5-dihydroxyphenyl)-3-pyridine-2-yl-propenone. Cytotoxic activity was measured using MTT assay. Compound 1-(2,5-dihydroxyphenyl)-3-pyridine-2-yl-propenone inhibited WiDr cell growth with the IC50 of  16 µM. Morphology of WiDr cell showed that compound 1-(2,5-dihydroxyphenyl)-3-pyridine-2-yl-propenone inhibited cell growth in dose dependent.Keywords:  compound 1-(2,5-dihydroxyphenyl)-3-pyridine-2-yl-propenone, WiDr colon cancer cell line, cytotoxic activity

Abstract

Penelitian ini bertujuan untuk mendeskripsikan pelaksanaan pembelajaran berbasis Edmodo pada mahasiswa Pendidikan Matematika Universitas Balikpapan. Subjek dalam penelitian ini adalah 12 mahasiswa Pendidikan Matematika Universitas Balikpapan yang sedang menempuh perkuliahan Teori Bilangan. Teknik pengumpulan data dilakukan dengan observasi (pengamatan terhadap aktivitas chat di dalam Edmodo), dokumentasi, serta tes hasil belajar. Adapun hasilnya didapatkan bahwa pelaksanaan pembelajaran berbasis Edmodo berjalan dengan baik. Hal ini dapat dilihat dari capaian hasil belajar mahasiswa yang menunjukkan secara rata-rata dari 12 mahasiswa memperoleh skor atau ketercapaian 82,53. Selain itu, mahasiswa juga merasa memperoleh pengalaman belajar yang baru melalui Edmodo, dapat lebih berekspresi, suasana belajar (chat) sangat santai, serta dapat diakses dimana saja jika mahasiswa lupa materi yang telah dipelajarinya. Hal ini dikarenakan materi yang disajikan telah diunggah di Edmodo maupun kanal Youtube. AbstractThis study aims to describe the implementation of Edmodo-based learning in Mathematics Education students at the University of Balikpapan. The subjects in this study were 12 University of Balikpapan Mathematics Education students who were taking lectures on Number Theory. Data collection techniques are done by observation (observation of chat activities in Edmodo), documentation, and learning achievement tests. The results were obtained that the implementation of Edmodo-based learning went well. This can be seen from the achievements of student learning outcomes which show an average of 12 students get a score or achievement of 82,53. In addition, students also feel they have gained a new learning experience through Edmodo, can be more expressive, the atmosphere of learning (chat) is very relaxed, and can be accessed anywhere if students forget the material they have learned. This is because the material presented has been uploaded on Edmodo and the Youtube channel.
