ABCE1 and colorectal cancer: To better validate this observation, we compared the levels of ABCE1 mRNA (Figure 10b) and protein (Figure 10c) in several colorectal cancer cells lines that are characteristic of different stages of colorectal cancer development (CaCo-2, HT-29, DLD-1, HCT116, and SW480) to the ones in a non-tumorigenic colorectal cell line (NCM460).
