In addition, CEABP1 was fused with the DNA-binding domain of human Max protein fused with a CPP to specifically deliver TCF/LEF TFD DNA, in which a TCF/LEF-binding sequence was concatenated with the Max-binding sequence, into CRC cells to competitively occupy the endogenous TCF/LEF in CRC cells, repress overactivated Wnt signaling, and suppress CRC cell proliferation. This evidence concerns the gene MAX and colorectal carcinoma.
