Nasopharyngeal carcinoma (NPC) is one of the common malignant cancers in China, and radiotherapy or chemotherapy is the main therapy method for NPC. Curcuminoids (or curcumin), natural antioxidants, have been recently shown to produce a potent chemopreventive action against several types of cancer. They have also displayed antioxidant and anti-inflammatory activities. In the present study, the antiproliferation and induced apoptosis effects of curcuminoids have been investigated in Detroit 562 cells (human pharynx carcinoma) and HONE-1 (human nasopharyngeal carcinoma) cells. Results indicated that curcuminoids have produced an inhibition of cell proliferation as well as the activation of apoptosis in these cancer cells. Both effects were observed to increase in proportion with the dose of curcuminoids. The DNA fragmentation, caspase-3 activation,and NF-?B transcriptional factor activity have been studied. By these approaches, apoptosis was induced by curcuminoids in the pharynx and nasopharyngeal cancer cells via caspase-3-dependent pathway. However, a different dependency has been observed, whereas proliferation inhibition and apoptosis depend upon the amount of curcuminoid treatment in the cancer cells.
