Abstract

Awar awar leaves which have not been optimally utilized in cancer treatment, are potential to be used in combination with doxorubicin (DOX), an agent used for chemotherapy. The aim of this experiment is to find out cytotoxic effect of awar-awar leaves ethanolic extract (ALE) and its combination with DOX towards breast cancer cells of T47D. ALE was prepared by macerating the dried-leaves powder with ethanol 70%. The cytotoxic effect of ALE toward breast cancer cells was tested employing MTT assay to the treatments both as a single agent and as a combination with doxorubicin (ALE DOX). The cytotoxicity was determined as IC50 value, while effectiveness of combination was measured by combination index (CI) to determine whether the effect is synergic, addictive, or antagonistic. Cytotoxic tests on single treatment ALE for a period of 24 hours resulted to a cytotoxic effect with IC so value of 13 µg/mL. ALE-DOX combination showed synergistic effect (CI < 1) on the concentration of 4.88 µg/mL (ALE) and 3.75 nM (DOX). The results showed that ALE is potential to be used as doxorubicin co-chemotherapeutic agent in breast cancer therapy.

Abstract

Doxorubicin is one of the standard regiment for breast cancer chemotherapy, but resistance to this agent is often occured and long period usage will induce cardiotoxicity, Therefore, combination therapy (co-chemotherapy) is needed to improve the efficacy of doxorubicin and to reduce its systemic toxicity. Naringenin is one of the most abundant ilavonoids in citrus fruits which showed cytotoxicity in various human cancer cell lines and has mechanisms through pathways except p53. This research is aimed to examine the effect of naringenin in combination with doxorubicin against T47D breast cancer cell which is resistant to doxorubicin due to p53 mutation. The IC50 dan CI (combination index) values were detennined by the MTT assay, The apoptotic stimulation effect of narigenin and doxorubicin was performed by DNA staining using cthidum bromide-acridine orange. Naringenin and doxorubicin exhibited cytotoxic effect with IC50 of 509 µM and 15 nM, respectively. The CI value in all ratios of naringenin-doxorubicin showed synergistic effect (CI 0.20-0.89). Combination ofnaringenin-doxorubicin with concentration smaller than 12,5 µM-0.6 nM in 1:1 ratio exhibited an additive combination effect, The combined treatment increased the apoptotic effect of doxorubicin.These results show that naringenin is potential to be developed as co-chemotherapeutic agent with doxonibicin, although the molecular mechanism is still needed to be explored.

Abstract

Previous experiments showed that curcumin analogue (PGV-1) inhibited breast cancer cell (T47D) growth at G2-M phase and induced cell apoptosis. This experiment was conducted to investigate the molecular effect of another curcumin analogue, PGV-0 and curcumin on the cell cycle progression and apoptosis as compared to the PGV-1. F lowcytometric method was conducted to analyze the effect of PGV-1 (2,5 µM), PGV-0 (5,0 µM) and curcumin (10,0 µM) on the cell distribution of various phase of T47D cell cycle. Western blot was also conducted to observe the effect of those compounds on proteins that involved in cell cycle (i.e. p21 and Cdc-Z) and apoptosis (Caspase-3/7/9). The results showed that PGV-1, PGV-0 and curcumin induced hyperploidy phenomenon on T47D cell. PGV-1 inhibited the cell cycle specifically on G2-M phase. Molecular observation showed that PGV-1 and PGV-0 were able to increase the expression of p21 protein and the Cdc-2 proteins, whilst curcumin was able to activate the Cdc-2 protein. The compounds have ability to induce apoptosis on T47D cell via Caspase3/7 activation. In conclusion, PGV-1, PGV-0 and curcumin inhibited the T47D cell cycle progression and induced cell apoptosis.

Abstract

Ekstrak etanol biji buah pinang (Areca catechu L.) menunjukkan efek sitotoksik pada sel kanker MCF7 dan WiDr. Penelitian ini bertujuan untuk mempelajari efek sinergisme antara ekstrak etanol biji buah pinang (AE) dan fraksi kioroforrnnya (ACF) dengan doxorubicin (Dox) dalam pemacuan apoptosis sel MCF7. Ekstrak etanol dipartisi dengan n-heksan dan kloroform untuk mendapatkan fraksi kloroforin. Efek sitotoksik.AE, ACF, dan Dox pada perlakuan tunggal dan kornbinasi ditentukan dengan metode MTT. Penganiatan apoptosis dilakukan dengan pengecatan DNA dengan akridin oranye-etidium bromida (double staining). Imunositokimia dilakukan untuk melihat ekspresi COX-2 dan Bax. Kombinasi Dox 100, 250, 334, dan 500 nM dengan AE 8 µg/ml; Dox 100 nM dengan AE 20 µg/ml; serta Dox 100 dan 250 nM dengan ACF 7 dan 18 µg/ml memperlihatkan efek sinergistis yang kuat (CI 0,1-0,3). Sernentara itu, kombinasi Dox 250, 334, dan 500 nM dengan AE 20, 27, dan 40 µg/ml; Dox 100 nM dengan AE 27 dan 40 µg/ml; Dox 100 nM dengan AE 20 µg/mi; Serta 500 nM dengan ACF 24 dan 35 µg/ml menunjukkan efek sinergistis (CI 0,3-0,7). Secara keseluruhan, kombinasi AE dan ACF dengan Dox memperiihatkan efek sinergistis pada MCF7 dengan indeks kombinasi (CI) kurang dari 0,9 (P<0,05). Periakuan kombinasi juga memacu apoptosis. Penekanan ekspresi Bcl-2 terjadi padaperlakuan kombinasi ACF-Dox. Hasil penelitian ini menunjulckan bahwa koinbinasi AE dan ACF dengan Dox memberikan efek sinergistis dalam pemacuan apoptosis dengan kemungkinan mekanisme meialui penekanan ekspresi Bcl-2.

Abstract

The synergic effects of n-butanolic fraction of secondary metabolite of endophytic fungus 1.3.11 (FB) and doxorubicin (Dox) on cell cycle regulation and the expression of Bcl-2 gene expression were investigated on MCF-7 and T47-D cells by iiow cytometry and immunocytochemical techniques respectively. The results showed that after 12 hours of incubation period with FB at its IC50 dose, MCF-7 cell cycle was inhibited at G1 phase while Dox inhibited the cell cycle at G2/M phase. Similar results were observed in T47-D cells when incubated with Dox and FB individually under the same treatment condition. Further treatment was then performed to these cells where both Dox and FB were combined at their IC50 and lC50 dose and added to incubate with the cells over 12 hours period. Interestingly, the modified treatment combination showed that MCF-7 and T47-D cell cycle regulation were inhibited at G2/M phase. Our immunocytochemical study also showed no significant inhibition suppression of Bel-2 gene expression in both MCF-7 and T47-D cells when compared with their corresponding positive control after treatment with FB and Dox or both combined FB and Dox at 1C50 and IC50 dosage over 15 hours incubation.

Abstract

Treatment of cancer such as surgery, radiotherapy and chemotherapy have many side effects such as cardiotoxicity, hepatotoxicity, and immunosuppressant, therefore selective cochemopreventive agent is needed. Awar-awar (Ficus septica) is a traditional medicinal plant that is known as a potential cancer chemopreventive agent. The purpose of this study was to determine the cytotoxic effect of ethanolic leaves extract of awar-awar (EFs) against 4T1 and MCF7/HER2 breast cancer cells; WIDR colon cells cancer, HeLa cervix cells cancer, and Vero normal cells. The cytotoxic test was performed by MTT assay. The parameter obtained from the cytotoxic test was IC50. Selectivity index was determined from IC50 ratio of cancer cells to normal cells Vero. The results showed that EFs has a cytotoxic activity on cancer cell line with IC50 61,2 µg/mL on 4T1; 48 µg/mL on MCF7/HER2; 122,4 µg/mL on Hela; 75,9 µg/mL on WiDR; and 394,8 µg/mL on Vero. It can be concluded that EFs has high selectivity on various cancer cells with selectivity index more than 3.
