摘要：
Aim:LINE-1 DNA methylation is a modifiable epigenetic process linked to colorectal cancer (CRC). However, studies of methylation in the tissue of interest are limited. This research examines associations between CRC risk factors and LINE-1 DNA methylation in healthy colon tissue.Materials & methods:LINE-1 methylation was measured in colon tissue samples from 317 patients undergoing a screening colonoscopy. Associations were examined with established CRC risk factors including alcohol consumption, smoking, BMI, NSAIDs, physical activity and fruit and vegetable consumption.Results:All studied risk factors were not related to LINE-1 DNA methylation in this population.Conclusion:The observed results may reflect that the effect of this set of established risk factors is not mediated through LINE-1 DNA methylation in the healthy colon.
