METHOD: This study systematically reviewed articles from 2013 to 2024 across five prominent databases; PubMed, Google Scholar, Web of Science, Scopus, and Science Direct, EMBASE, Cochrane library and DOAJ. The study eligibility criteria include original studies assessing using gastric cancer cell lines and articles utilizing extracted andrographolide from Andrographis paniculata or standard andrographolide source treatment. The following exclusion criteria were articles written in a different language, review articles, book chapters, conference articles, scientific reports. Duplicated articles were removed using Mendeley software.
RESULT: Out of 93 articles, six were relevant, primarily focusing on in vitro analyses with gastric adenocarcinoma cell lines.
CONCLUSION: These studies indicate that andrographolide can hinder the cell cycle, suppress cell proliferation, alleviate oxidative stress, and induce apoptosis by prompting gastric cancer cells to undergo self-destruction, which is a crucial mechanism for controlling and eliminating cancerous growths.
MATERIALS AND METHODS: This study aimed to assess the effects of commercial and recombinant bromelain on the cytokinetic behavior of MCF-7 breast cancer cells and their potential as therapeutic alternatives in cancer treatment. Cytotoxic activities of commercial and recombinant bromelain were determined using (sulforhodamine) SRB assay. Next, cell viability assays were conducted to determine effects of commercial and recombinant bromelain on MCF-7 cell cytokinetic behavior. Finally, the established growth kinetic data were used to modify a model that predicts the effects of commercial and recombinant bromelain on MCF-7 cells.
RESULTS: Commercial and recombinant bromelain exerted strong effects towards decreasing the cell viability of MCF-7 cells with IC50 values of 5.13 μg/mL and 6.25 μg/mL, respectively, compared to taxol with an IC50 value of 0.063 μg/mL. The present results indicate that commercial and recombinant bromelain both have anti-proliferative activity, reduced the number of cell generations from 3.92 to 2.81 for commercial bromelain and to 2.86 for recombinant bromelain, while with taxol reduction was to 3.12. Microscopic observation of bromelain-treated MCF-7 cells demonstrated detachment. Inhibition activity was verified with growth rates decreased dynamically from 0.009 h-1 to 0.0059 h-1 for commercial bromelain and to 0.0063 h-1 for recombinant bromelain.
CONCLUSIONS: Commercial and recombinant bromelain both affect cytokinetics of MCF-7 cells by decreasing cell viability, demonstrating similar strength to taxol.
METHODS: Different methods including flow cytometry, comet assay and reverse transcription-polymerase chain reaction (RT-PCR) were used to show the effects of juice exposure on the level of DNA damage and the reduction of cancerous cells. MTT assay is a colorimetric method applied to measure the toxic effects of juice on cells.
RESULTS: The Centella asiatica juice was not toxic to normal cells. It showed cytotoxic effects on tumor cells in a dose dependent manner. Apoptosis in cells was started after being exposed for 72 hr of dose dependent. It was found that the higher percentage of apoptotic cell death and DNA damage was at the concentration above 0.1%. In addition, the juice exposure caused the reduction of c-myc gene expression and the enhancement of c-fos and c-erbB2 gene expressions in tumor cells.
CONCLUSIONS: It was concluded that the Centella asiatica juice reduced liver tumor cells. Thus, it has the potential to be used as a chemopreventive agent to prevent and treat liver cancer.
