Project Description

Vitamin D and sodium butyrate, generated by the fermentation of dietary fiber are both regulators of colon maturation and gene expression. They regulate gene expression through a process called transcriptional attenuation. Since the mechanisms of transcriptional attenuation are largely unknown this study sought to examine and characterize the candidate genes for transcriptional attenuation using a novel, custom built microarray analysis to understand the nature and regulatory mechanisms recruited by two nutritional factors that coordinate colonic cell maturation.
