Japan has been moving towards a super aging society, resulting in a rapidly increasing prevalence of lifestyle diseases, including colon cancer.
Japanese patients survey by the Ministry of Health, Labour and Welfare reported 235,000 colon cancer patients in 2015, and this number is quickly increasing due to the change of dietary life style from the typical Japanese food to the westernized style food.
Although the cancer chemotherapy has been widely developing recently, some natural product support, having wide spectra of bioactivity, however mild, are required.
Saffron finds use as folk medicines as well as a flavoring and a coloring agent.
Saffron consists of three main chemical components; red color, crocetin glycosides; a bitter taste, picrocrocin; and spicy aroma, safranal. In this chapter, we evaluate the activities of saffron extracts and a major crocetin glycoside, crocin. against colorectal cancer in in vitroand in vivotrials.
Saffron crude extracts, which contain approximately 40% of crocin, significantly inhibited the growth of colorectal cancer cell lines HCT-116, HT-29 and SW-480, although crocin did not affect for non-cancer cells.
Crocin significantly inhibited the development of colonic adenocarcinomas induced by azoxymethane and dextran sodium sulfate in mice during 18 weeks feeding.
The crocin feeding experiment for 4 weeks evidently inhibits the dextran sodium sulfate induced colitis and, then, the clear suppression for the mRNA expression of tumor necrosis factor , interleukin- (IL-) 1 ,IL-6, interferon , NF- B, cyclooxygenase-2, and inducible nitric oxide synthase, and the increase of Nrf2 mRNA expression in the colorectal mucosa occurred.
From these results we suggest that crocin can suppress chemically induced colitis and colitis-related colon carcinogenesis in mice mainly through the inhibition of inflammation related cytokines, indicating that saffron and crocin are suitable candidates for the prevention of colitis and inflammation-associated colon carcinogenesis.
We further review the supporting phenomena like strong anti-oxidant and anti-inflammation activities of crocin using our previous publications

| Abstract: | Japan has been moving towards a super aging society, resulting in a rapidly increasing prevalence of lifestyle diseases, including colon cancer. Japanese patients survey by the Ministry of Health, Labour and Welfare reported 235,000 colon cancer patients in 2015, and this number is quickly increasing due to the change of dietary life style from the typical Japanese food to the westernized style food. Although the cancer chemotherapy has been widely developing recently, some natural product support, having wide spectra of bioactivity, however mild, are required. Saffron finds use as folk medicines as well as a flavoring and a coloring agent. Saffron consists of three main chemical components; red color, crocetin glycosides; a bitter taste, picrocrocin; and spicy aroma, safranal. In this chapter, we evaluate the activities of saffron extracts and a major crocetin glycoside, crocin. against colorectal cancer in in vitroand in vivotrials. Saffron crude extracts, which contain approximately 40% of crocin, significantly inhibited the growth of colorectal cancer cell lines HCT-116, HT-29 and SW-480, although crocin did not affect for non-cancer cells. Crocin significantly inhibited the development of colonic adenocarcinomas induced by azoxymethane and dextran sodium sulfate in mice during 18 weeks feeding. The crocin feeding experiment for 4 weeks evidently inhibits the dextran sodium sulfate induced colitis and, then, the clear suppression for the mRNA expression of tumor necrosis factor , interleukin- (IL-) 1 ,IL-6, interferon , NF- B, cyclooxygenase-2, and inducible nitric oxide synthase, and the increase of Nrf2 mRNA expression in the colorectal mucosa occurred. From these results we suggest that crocin can suppress chemically induced colitis and colitis-related colon carcinogenesis in mice mainly through the inhibition of inflammation related cytokines, indicating that saffron and crocin are suitable candidates for the prevention of colitis and inflammation-associated colon carcinogenesis.
