The results showed that AP2/ERF-ERF (CZG_jg5663), LIM (CZG_jg21577), and HB-HD-ZIP (CZG_jg17873) exhibited relatively high expression levels in the core region, possibly contributing to the difference in CRC peel between the core region and other regions (Fig. 7d). This evidence concerns the gene ERF and colorectal carcinoma.
