CREPT facilitates colorectal cancer growth through inducing Wnt/β-catenin pathway by enhancing p300-mediated β-catenin acetylation.

ABSTRACT: Using whole genome sequencing, we identified gene amplification of CREPT in colorectal cancer (CRC). In this study, we aim to clarify its clinical significance, biological effects, and mechanism in CRC. CREPT was upregulated in CRC cell lines and in 47.37% (72/152) of primary CRC tumors. Amplification of CREPT was detected in 48.28% (56/116) of primary CRC tumors, which was positively correlated with its overexpression (P < 0.001). Multivariate analysis showed that CRC patients with CREPT protein overexpression were significantly associated with poor disease-free survival (P < 0.05). CREPT significantly accelerated CRC cell proliferation and metastasis both in vitro and in vivo. RNA-sequencing (seq) analysis uncovered that the tumor-promoting effect by CREPT was attributed to enhancing Wnt
