ABSTRACT
It has been widely recognized that microRNAs are involved in nearly all cellular processes that have been investigated and contribute to a variety of diseases including cancer. Our prior studies demonstrated the depletion of one-carbon metabolism related B-vitamins, including folate, vitamin B2, B6 and B12, induced a genomic DNA hypomethylation and an elevation of the tumorigenic Wnt signaling in mouse colonic epithelium. The present study aimed to define whether microRNAs serve as mediators between these B-vitamins and the Wnt signaling, and thereby influence intestinal tumorigenesis. MicroRNA expression profiles were measured using miRNA microarray and real-time PCR on colonic epithelial …
