| Abstract |
Colon cancer is the third most common cancer causing high mortality rates world-wide. In light of recorded incident, hence, the present study aimed to investigate the effect of RT2, a modified cationic Leucrocin I peptided from Crocodylus siamensis, against HCT-116 human colon cancer cell lines. Using MTT assay, results demonstrated that RT2 at the concentrations of 37.5, 75 and 150 µg/mL exhibited strong cytotoxic effect against HCT-116 cell lines after 24 h of treatment (IC50 = 87.84 µg/mL). This peptide found to be non-toxic to Vero cells. Additionally, RT2 treatment caused a significant reduction in the colony forming ability of cancer cells. A remarkable suppression of cancer cells migration was observed after treatment with RT2, indicating potent anti-metastatic properties. The mechanism involved in cancer cell cytotoxicity of this peptide was shown to be associated with the induction of apoptosis, as evidenced by annexin V-FITC/PI staining flow cytometry analysis. Moreover, the molecular mechanisms of RT2 in apoptosis induction were observed to decrease the mRNA expression levels of Bcl-2 and XIAP and increase expression of Cytochrome C, Caspase-3, and Caspase-9. These collected data clearly demonstrated that RT2 offered great potential in the treatment of human colon cancer cells. |
