Background: Colorectal cancer (CRC) is a leading cause of cancer mortality worldwide. Mutations in the adenomatous polyposis coli (APC) gene are pivotal in colorectal tumorigenesis. Recently, we demonstrated that aldehyde dehydrogenase
Data from several studies suggest that a diet high in meat, including processed meat and fat, may have an association with the development of colorectal cancer (CRC).
The present study aimed to investigate the relationship between meats, dairy products, fat consumption and the risk of CRC in
OBJECTIVE
Animal studies have demonstrated that dietary supplementation with flaxseed oil inhibits colorectal cancer growth. Recent data indicate that walnuts have strong antiproliferative properties against colon cancer cells in vitro but no previous study has assessed the effects of walnuts in
Rats fed either fish oil (n = 16) or corn oil (n = 16) in calorically and nutritionally balanced diets were injected with 1,2-dimethylhydrazine, which is a colorectal specific carcinogen; differential colorectal tumor induction was then measured. In addition, plasma peroxide concentrations were
Colorectal cancer (CRC) has been linked to dietary consumption of benzo[a]pyrene (B[a]P). 6-Gingerol (6-G), a component of ginger has been reported to possess anti-inflammatory and antioxidant activities, but little is known regarding the mechanism of 6-G in CRC chemoprevention. We therefore
OBJECTIVE
How colorectal cancer develops resistance to gamma-radiation is not fully understood, but the transcription factor nuclear factor-kappaB (NF-kappaB) and NF-kappaB-regulated gene products have been proposed as mediators. Because curcumin, a component of turmeric (Curcuma longa), has been
Excessive consumption of beverages sweetened with high-fructose corn syrup (HFCS) is associated with obesity and with an increased risk of colorectal cancer. Whether HFCS contributes directly to tumorigenesis is unclear. We investigated the effects of daily oral administration of HFCS in adenomatous
Over the past several decades, the incidence of early-onset colorectal cancer (EOCRC; in patients <50 years old) has increased at an alarming rate. Although robust and scientifically rigorous epidemiological studies have sifted out environmental elements linked to EOCRC, our knowledge of the
Human colon carcinoma COLO 205, carrying wild type p53, grown subcutaneously in athymic mice was inhibited 80% by a high fat menhaden oil diet containing a mixture of omega-3 fatty acids compared to the low fat corn oil diet containing omega-6 fatty acids. Feeding a high fat diet of golden algae oil
Traditional Chinese herbal medicines are widely accepted as an option for the treatment of colorectal cancers. Danshen (Salviae miltiorrhizae Radix) is widely prescribed in traditional Chinese medicine for cardiovascular diseases. Tanshinone IIA (Tan-IIA) is extracted from Danshen. Our previous
BACKGROUND
We wanted to investigate the relationship between the fecal levels of granulocyte marker protein (GMP) and the presence of aberrant crypt foci (ACF) and colorectal cancer in rats given injections of azoxymethane (AOM) and fed either of two different diets, a basal diet plus 20% corn oil
Manganese superoxide dismutase (MnSOD) is an important mitochondrial antioxidant. Alteration in the regulation of MnSOD activity has been proposed to play a critical role in the development of many types of tumors. Colorectal cancer is one of the most common human malignancies and has been shown to
Dietary flaxseed has been shown to prevent azoxymethane (AOM)-induced colorectal cancers in male Fisher rats. The present study was designed to investigate the chemopreventive effects of dietary flaxseed on the development of intestinal tumors in Apc(Min) mice. Apc(Min) mice were divided into five
OBJECTIVE
Epidemiological evidence suggests n-3 polyunsaturated lipids may protect against colorectal neoplasia. Consumption of fish oil modulates crypt cytokinetics in humans, and crypt apoptosis in animal models. To explore these effects, we investigated involvement of caspase enzymes and cellular
The effects of saturated and polyunsaturated dietary lipids on intestinal mucosal cell proliferation were investigated in rats. Animals were randomly allocated to three groups of 10, and fed fibre-free diets containing lipid in the form of lard, corn oil or fish oil at a level of 80 g/kg. Total
