Investigation of apoptotic effect of juglone on CCL-228-SW 480 colon cancer cell line
Background: Colon cancer is a major cause of morbidity and mortality in the world. Juglone is a natural compound which has been isolated from Juglans mandshurica Maxim, and it has various pharmacological effects such as antiviral, antibacterial, and anticancer. In our study, we aimed to investigate the effect of juglone on CCL-228-SW 480 colon carcinoma cell line in monolayer and spheroid culture medium. Materials and Methods: The CCL-228-SW 480 cell lines were cultured in both monolayer and spheroid cultures. Cells were treated with juglone at 24, 48, and 72 h of incubation. ID50 inhibition was determined on the dose for juglone and after it was found 20 μM was applied to the cells to examine the effect of juglone on CCL-228-SW 480 colon carcinoma cell line. After Juglone was applied the BrdU marking index, Transferase dUTP Nick ends Labeling (TUNEL) assay, active caspase-3 assay, apoptosis-inducing factor (AIF) assay were determined by immunohistochemistry in both the monolayer and spheroid cultures. Results: The control group had a healthy pattern of S-phase fraction, and many of the CCL-228-SW 480 cells nuclei were observed to be positive for BrdU. Terminal Deoxynucleotidyl TUNEL-positive cells, active Caspase-3, and AIF were detected after treatment with juglone in both the monolayer and spheroid cultures. Conclusions: The dead cell count was higher in the CCL-228-SW 480 cell lines with juglone applied than in the controls. Juglone significantly inhibits the proliferation and induces the apoptosis of CCL-228-SW 480 cells in vitro.
