Extracts of Clove (Syzygium aromaticum)‎ Potentiate FMSP-Nanoparticles Induced Cell Death in MCF-7 Cells

Abstract EN

Both nanoparticles and cloves (Syzygium aromaticum) possess anticancer properties, but they do not elicit a significant response on cancer cells when treated alone.

In the present study, we have tested fluorescent magnetic submicronic polymer nanoparticles (FMSP-nanoparticles) in combination with crude clove extracts on human breast cancer cells (MCF-7) to examine whether the combination approach enhance the cancer cell death.

The MCF-7 cells were treated with different concentrations (1.25 μg/mL, 12.5 μg/mL, 50 μg/mL, 75 μg/mL, and 100 μg/mL) of FMSP-nanoparticles alone and in combination with 50 μg/mL crude clove extracts.

The effects of FMSP-nanoparticles alone and combined with clove extracts were observed after 24 hrs and 48 hrs intervals.

The response of FMSP-nanoparticles-treated cells was evaluated by Trypan Blue, 4′,6-diamidino-2-phenylindole (DAPI), and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays, respectively.

We have demonstrated that cancer cell viability was decreased to 55.40% when treated with FMSP-nanoparticles alone, whereas when cancer cells were treated with FMSP-nanoparticles along with crude clove extracts, the cell viability was drastically decreased to 8.50%.

Both morphological and quantitative data suggest that the combination of FMSP-nanoparticles plus crude clove extracts are more effective in treating cancer cells and we suggest that the combination treatment of nanoparticles along with clove extracts hold a great promise for the cancer treatments.
