In a previous study using a new bioinformatic approach based on Chip-Seq data with antibodies to various transcription factors , histone markers , and ChiA-PET and RNA-seq data, 32 potentially regulatory single -nucleotide polymorphisms (SNPs) were associated with colorectal cancer . In this study, a functional analysis of 6 of these polymorphisms was performed using EMSA and the luciferase reporter system. These nucleotide substitutions have been shown to alter the binding of oligonucleotides to nuclear extract proteins and alter the expression of the reporter gene.
