Abstract
Proximal promoters are located upstream of the transcription start sites of genes, and they contain regulatory sequences on which bind different transcription factors for promoting colorectal cancer progression. Here we describe the comprehensive methodology used previously for the identification and functional characterization of MYC-responsive elements in the integrin α1 subunit (ITGA1) gene using a combination of in silico analysis, site-directed mutagenesis, and chromatin immunoprecipitation.
Keywords:
