Abstract

Indonesians have a rich tradition of incorporating black rice into their diet as a functional food due to its high antioxidant content. This research investigates the effects of the ethanolic extract of "Sembada Hitam" black rice bran on T47D breast cancer cells, specifically its cytotoxic, cell growth, and apoptotic induction properties. The MTT assay method was used to evaluate the cytotoxicity of the black rice bran extract on T47D cells after 24 and 48 hours of incubation. The acridine orange/propidium iodide (AO/PI) dye double staining method was employed to assess the apoptosis-inducing properties of the extract. Additionally, a cell growth assay was conducted to evaluate the effect of the extract on cell growth, with observations recorded on days 0, 3, and 6. The results revealed that the ethanolic extract of black rice bran "Sembada Hitam," when administered at various concentrations ranging from 7.81 to 1000 µg/mL, did not exhibit cytotoxic effects on T47D cells during the 24 and 48 hours of incubation. The cell growth assay revealed that T47D cells treated with the ethanolic extract of "Sembada Hitam" black rice bran at concentrations of 250 and 500 µg/mL exhibited lower growth rates than the 1% DMSO group from the 3rd to 6th day after incubation. The ethanolic extract of "Sembada Hitam" at concentrations of 250, 500, and 1000 µg/mL resulted in cell death of 10.64 ± 2.98%, 9.99 ± 5.87%, and 5.84 ± 0.78%, respectively. In conclusion, this study found that the ethanolic extract of "Sembada Hitam" black rice bran did not demonstrate significant cytotoxic effects on T47D breast cancer cells and is, therefore, unlikely to be a suitable candidate for an anti-cancer agent.

Abstract

Oxidative stress induced by hydrogen peroxide (H2O2) can lead to cellular damage, contributing to degenerative diseases and aging. Black rice bran is a functional food known for its antioxidant properties, which are crucial in reducing the adverse effects of oxidative stress and maintaining redox balance. In this study, we aimed to investigate the protective effect of the extract of black rice bran (EBRB) 'Sembada Hitam' on Vero cells against H2O2 toxicity. To evaluate the protective effect, a co-culture method was employed, and cell viability was assessed using the MTT assay. Additionally, cell growth was examined through trypan blue staining. Vero cells were exposed to different concentrations of H2O2 and EBRB for a 24-hour period. The results demonstrated that EBRB at concentrations of 15.625, 250, and 500 μg/mL exhibited a protective effect on Vero cells exposed to H2O2 at concentrations of 100, 200, and 400 μM, respectively. Notably, when Vero cells were treated with EBRB at concentrations of 250 or 500 μg/mL for five days in conjunction with H2O2 exposure at concentrations of 200 or 400 μM for 24 hours, a significant decrease in cell viability was observed on day 3. Based on the collective findings, it can be concluded that EBRB has the potential to protect Vero cells against H2O2 -induced toxicity, but primarily during a short-term incubation period. Overall, this study highlights the protective properties of EBRB against H2O2 -induced cellular damage and emphasizes the importance of further investigations to fully elucidate the underlying mechanisms and potential long-term effects of EBRB on cell viability.
