| Abstract: | The modulating effect of curcumin and ferulic acid was investigated on expression pattern of apoptosis regulatory p53 and bcl-2 proteins in oral squamous cell carcinoma (OSCC). The OSCC was induced in the buccal pouch of golden Syrian hamster by painting with 0.5% 7,12-dimethylbenz[]anthracene (DMBA) three-times a week for 14 weeks. The expression pattern of p53 and bcl-2 proteins was analyzed by immunohistochemical staining. We noticed 100% tumor formation in hamsters painted with DMBA alone for 14 weeks. Overexpression of p53 and bcl-2 proteins was observed in the buccal mucosa of tumor-bearing hamsters. Oral administration of curcumin (80 mg/kg body wt) and ferulic acid (40 mg/kg body wt) to DMBA painted hamsters on days alternate to DMBA painting for 14 weeks completely inhibited tumor formation and down-regulated the expression pattern of p53 and bcl-2 proteins. Our results thus demonstrated the protective role of curcumin and ferulic acid on DMBA-induced abnormal expression of p53 and bcl-2 proteins in the buccal mucosa of golden Syrian hamsters. |
