Abstract
ABSTRACTDietary components with potent anticancerous property are gaining attention as therapeutic agents due to low cost of therapy and minimal toxic effects. Turmeric is one such miracle spices of Indian and South Asian recipes with multiple medicinal properties. The anticarcinogenic properties of its active compound curcumin have been studied in detail. However, studies on the medicinal properties of crude turmeric used as dietary agents are lacking. Therefore, in this study we investigated the effects of dietary and topical crude turmeric paste on DMBA induced skin tumor of male Wistar rats. We observed the apoptotic effect of crude turmeric paste on DMBA induced tumor with depletion of T cells response. Our results demonstrated the significant expression of major pro-apoptotic genes like caspase-2, 3, 8, 9, PARP, and p53 and down regulation of major pro-inflammatory (NF-κB) and pro-angiogenic factors and (VEGF) in turmeric treated tumor tissues. We also observed significant decrease in CD4+, CD8+, and Natural Killer cell population as compared to the untreated group.
