Active TGF-β1 correlates with myofibroblasts and malignancy in the colorectal adenoma-carcinoma sequence

Hawinkels, L.J.A.C. (author), Verspaget, H.W. (author), van der Reijden, J.J. (author), van der Zon, J.M. (author), Verheijen, J.H. (author), Hommes, D.W. (author), Lamers, C.B.H.W. (author), Sier, C.F.M. (author), TNO Kwaliteit van Leven (author)

Transforming growth factor-β1 (TGF-β1), a cytokine involved in various stages of cancer, is produced as a latent complex and requires processing to become active. We have determined total and active TGF-β1 levels in homogenates of colorectal neoplasia. In contrast to total TGF-β levels, showing a stepwise increase in the mucosa-adenoma-carcinoma...

Dietary glycemic load, glycemic index and colorectal cancer risk: Results from the Netherlands Cohort Study

Weijenberg, M.P. (author), Mullie, P.F.F. (author), Brants, H.A.M. (author), Heinen, M.M. (author), Goldbohm, R.A. (author), van den Brandt, P.A. (author), TNO Kwaliteit van Leven (author), KvL (author)

Since hyperinsulinemia is implicated in the development of colorectal cancer, determinants of serum insulin levels, like the glycemic load and the glycemic index of the diet, could influence cancer risk. Our objective was to evaluate whether a diet with a high glycemic load or glycemic index is associated with increased colorectal cancer risk....

Adequate intake of folate, methionine, riboflavin, and vitamin B-6 may prevent aberrant DNA methylation and thereby protect against colorectal cancer (CRC). However, previous epidemiological studies investigating associations between dietary intakes of these nutrients and CRC have been inconsistent. We investigated the associations between...

Intake of dietary factors that serve as methyl group donors may influence promoter hypermethylation in colorectal carcinogenesis. We investigated whether dietary folate, vitamin B2 and vitamin B6, methionine and alcohol were associated with mutL homologue 1 (MLH1) hypermethylation and the related molecular phenotypes of MLH1 protein expression,...

High alcohol consumption is related to colorectal cancer (CRC). Our objective was to study associations between alcohol consumption and risk of CRC according to characteristics of aetiological pathways: the chromosomal instability (CIN) and the microsatellite instability (MIN) pathway. We classified CIN+ tumours (tumours with either a truncating...

Nutrition in the prevention of gastrointestinal cancer

van den Brandt, P.A. (author), Goldbohm, R.A. (author), TNO Kwaliteit van Leven (author)

Diet has been hypothesized to play a role in the etiology of gastrointestinal cancer for a long time. Initially, strong evidence of such effects was found in retrospective epidemiological studies. Dietary habits, in particular those from the distant past, are difficult to measure, however. Results from recent, prospective and larger studies of...

The effect of the flavonoid quercetin and its conjugate rutin was investigated on (biomarkers of) colorectal cancer (CRC). Male F344 rats (n = 42/group) were fed 0, 0.1, 1, or 10 g quercetin/kg diet or 40 g rutin/kg diet. Two wk after initial administration of experimental diets, rats were given 2 weekly subcutaneous injections with 15 mg/kg...

The effect of the dietary flavonoid quercetin was investigated on proliferation and differentiation of the human colon cancer cell line Caco-2. Confluent Caco-2 monolayers exposed to quercetin showed a biphasic effect on cell proliferation and a decrease in cell differentiation (0.001<P<0.05). During differentiation Caco-2 cells formed 5 phase...

Heme and chlorophyll intake and risk of colorectal cancer in the Netherlands cohort study

Background: The evidence for red meat as a determinant of colorectal cancer remains equivocal, which might be explained by differences in heme content. Heme is the prooxidant, iron-containing porphyrin pigment of meat and its content depends on the type of meat. Chlorophyll from green vegetables might modify this association. Methods: The...

Background: Studies in animals have suggested that calcium may reduce the risk of colorectal cancer. However, results from epidemiologic studies of intake of calcium or dairy foods and colorectal cancer risk have been inconclusive. Methods: We pooled the primary data from 10 cohort studies in five countries that assessed usual dietary intake by...
