Colorectal cancer is one of the most common types of cancer in the world and the study of the role of nutrients in preventing or inhibiting the growth of this cancer is of interest to scientists. In this article, the synergistic effect of deuterium-depleted water(DDW) and crocin at specific concentrations on HT-29 cells was investigated. In this regard, HT-29 cells were grown in RPMI medium containing DDW, alone and in combination with crocin for 24, 48 and 72 h. Cell viability, cell cycle changes and antioxidant enzymes status were determined by MTT assay, flow cytometry and quantitative luminescence methods, respectively. The results of these analyses proved the cell growth inhibitory effect of deuterium alone and its synergistic effect in combination with crocin. The cell cycle analysis showed an increase in the number of cells in the G0 and G1 phases whereas there was a decrease in the number of cells in the S, G2 and M phases. The activities of superoxide dismutase and catalase enzymes also decreased compared to the control group that is a reason to increase Malonyl dialdehyde factor. The results suggested that a combination of DDW and crocin can open a new strategic approach in the prevention and treatment of colorectal cancer.
